mitters over 15 years in the making. Its broadband no-tune design allows 87.5 - 108MHz operation without requiring tuning or calibration. The inclusion of four-band DSPX audio processing means stations without a ded-

icated processor sound great, right out of the box. Those who already have external pro-

cessing benefit from BW Broadcasts unique dual-loop virtual VFO exciter and field proven ultra-low distortion modulator integrated into a great performing, highly stable FM transmis-

sion system. Features such as slide-in power supplies, and unique solder-free Gold-Clamp transistors (on most models) make in-field maintenance simple. A high resolution OLED screen displays RF, audio and system parameters. The control wheel and three front panel buttons allow easy navigation of the menus. Help tips for every param-

eter make setup simple. Every TX-V2 Transmitter features a LAN connection for Ethernet local or remote control. The LAN connection also supports SNMP, telnet, and email alerts via either SMTP or BW Broad-

casts mail server. Where a LAN connection is not available, the RS232 connection can be used. Intelligent alarms and email alerts ensure busy engineers can manage their stations with min-

imal intervention. A real time clock and comprehensive logging is available for those who like to see more detailed status. Also present are 4 rear panel opto-isolated triggers that al-

low external equipment to control the transmitter. It is advised that this manual is read to learn all of the advanced features of the TX-V2 Trans-

mitter. 9 Warranty 2 Please ensure the Warranty Registration process is completed upon receipt of this product. To do so go to www.bwbroadcast.com/warranty with your products serial number to hand.

Never power on an FM transmitter without a suitable antenna or dummy load connected. The V2 Transmitters protection circuitry will prevent any internal damage, but it is not advis-

able to run an FM transmitter without a load connected. Setting up a V2 Transmitter couldnt be any easier. First connect either analogue audio to the left and right back panel connectors (10 and 11), digital audio AES/EBU into the left hand connector (10) or feed the MPX input (13) from an audio processor. Connect the RF output

(18) to a 50Ohm antenna of the correct power handling capability. Connect the required remote control / monitoring ports (Ethernet, RS232, Alarms/Triggers Port). The transmitters frequency and power are both set from the RF Settings menu:

Input selection, pre-emphasis, processing and the stereo parameters are set in the audio set-

tings menu:

Input Selects analog or digital input to the transmitters built in stereo encoder/audio proces-

sor. For analog, connect to left and right XLR Inputs. For digital, connect an AES/EBU connec-

tion to the left hand XLR input. Pre emphasis Sets pre emphasis to off, 50S (Europe/Japan) or 75s (Americas). Processing Preset Selects the processing preset on the integrated 4-band DSPX audio proces-

sor. 26 Encoder Selects the stereo generator mode, from either: Stereo, Mono L+R, Mono L, Mono R and Swap L + R. MPX Source Selects if the MPX source for the exciter is internal or external. If using the V2 trans-

mitter with no external equipment (RDS, audio processor etc) then set to internal. If using any external equipment set to external. When set to internal, the MPX In and MPX Out connectors are internally connected. which routes the internal stereo generator directly to the exciter. When set to external, the internal the internal stereo generator and audio processor are still functioning, but the MPX in and MPX out connections are not internally connected, allowing MPX signals to be routed to and/or from external equipment. 7.2 Examples of Use 7.2.1 Transmitter with an external RDS encoder and internal audio processing 1. Place the transmitter in a well ventilated space. 2. Connect the antenna to the RF output connector on the back of the transmitter. 3.

In this setup, the stereo multiplex is generated in the audio processor, it is then fed through the RDS encoder where the RDS subcarrier is added. It is then fed directly into the transmitters exciter. Note that the transmitters onboard processing will have no effect on the signal in this configuration. 7.2.4 Transmitter with an external audio processor and RDS (Side Chain Connection) 30 1. Place the transmitter in a well ventilated space 2. Connect the antenna to the RF output connector on the back of the transmitter. 3. Connect the MPX output of your audio processor (or stereo generator) to the MPX input on the back of the transmitter. 4. Connect the Pilot output of your audio processor (or stereo generator) to the pi-

lot/reference input on your RDS encoder. 5. Connect the MPX output of your RDS encoder to the SCA input on your audio processor. 6. Plug the power cord into the power supply module on the rear panel of the transmitter. 7. Connect the required remote control Alarms/Triggers Port).

(Ethernet, RS232, 8. Once the transmitter is operating, set the correct carrier frequency and power from the RF settings menu. Check reflected power is OK. 9. In the RF settings menu, set MPX source to external. 10. Check the modulation level - if the modulation level is low, adjust the MPX output level on your audio processor (or stereo generator) and/or the MPX input level on the back of the transmitter. The maximum modulation should not exceed 75kHz. 11. Check the documentation that came with your audio processor on how to set/check the proper pilot injection level. 12. Check the documentation that came with your RDS encoder on how to set/check the proper RDS injection level. In this setup, the audio stereo multiplex is generated in the audio processor. The RDS data is fed into the audio processor where it is combined with the audio multiplex. This combined signal is fed directly into the transmitter exciter. Note that the transmitters onboard process-

ing will have no effect on the signal in this configuration. This is the best connection in terms of pilot and RDS subcarrier phase synchronization and MPX spectrum cleanliness. 31 Part III System Configuration 32 Operation Guide 8.1 RF Settings 8 N.B. Never power on an FM transmitter without a suitable antenna or dummy load con-

nected. The V2 Transmitters protection circuitry will prevent any internal damage, but it is not advisable to run an FM transmitter without a load connected. 8.1.1 Basic Setup 1. Select the required Frequency. Note that the frequency displayed on the Status box will flash for a few seconds, indicating that the system is out of lock and hast not reached the frequency. Once locked, the value will become steady. 2. Select the required Power. The system will take some time to ramp the power to the se-

lected value. During this time, the value displayed in the Status box will flash. 3. Set the MPX Source parameter. This selects the source for the exciter. Select Internal if the analog/digital inputs are used. (which are connected to the built-in audio proces-

sor) or External if the transmitter is used with an external audio source connected to its MPX BNC input. 4. Select whether you require the unit to send the FSK ID every hour. If enabled, enter the FSK ID. 5. If the unit is required to mute the RF output on silence detection, then select set RF Mute on Silence to the amount of time after which the transmitters output will be muted if the transmitter is transmitting silence. (Note that the unit understands silence as a signal that produces less than 30 kHz modulation. Look at the Deviation meter DEV: on the status box). 6. RF Mute (Manual) must be switched to off (once the unit is set-up) to begin transmission. 8.1.2 Power Scheduler This feature will switch the output power of the unit to an alternate value set at Power Sched-

uler ) Power during the selected time interval. This feature is intended to allow users to lower the power of their transmission at night time to reduce power consumption and avoid in-

creasing the range of the transmission due to the change in atmospheric conditions. In order to setup the feature:

1. In Power, select the power that the unit will use during the scheduled interval 2. Select the Start Time at which the unit will switch to the alternate scheduled power. 33 3. Select the Finish Time at which the unit will switch to the normal power RF Settings ) Power. 4. Current Time is the system time. This is displayed here as a reference for selecting the start and finish times. It can also be adjusted if required. 5. Set Enable to Enabled. The power Scheduler is now running. 8.2 Audio Settings BW Broadcasts range of award winning DSPX audio processors has become known for their features, performance and value for money. Integrated within all V2 Transmitters is the 4-

band DSPXmini FM SE. The analogue and digital inputs (XLRs) are connected to the proces-

sor. Set up:

1. Select MPX source as required. Set to Internal if the analog or digital inputs (XLRs) are used or external if the MPX in BNC socket is used (e.g.: to connect an external audio processor). When set to Internal, the built-in audio processor will be used. In this case:

1. Set the Audio Input to Analog or Digital. 2. Set the required Processing preset. 3. Select the desired Pre-emphasis characteristic (off, 50us (for EU) or 75us (for Americas)) 4. Select the Audio Mode (Stereo, Mono L+R, Mono L, Mono R, Swap L/R). Selecting mono disables the stereo pilot and subcarrier. 8.3 Triggers V2 Transmitters have a comprehensive monitoring and control system consisting of 3 alarms and 4 trig-

gers. Pin 2 of the connector is hardwired to RF mute. Connecting this pin to ground will mute the transmit-

ter. The alarms and triggers port can also be used to control the unit through a telemetry interface system. Trigger pins are designed to work with relay contacts to ground or 5 V drivers able to sink 15 mA (per trigger pin). 34 Figure 8.1: Alarms and Triggers Port Triggers are used to control certain parameters on the V2 Transmitter using the relevant pins on the rear alarms and triggers connector. To fire a trigger, the pin must be pulled low. To set up a trigger:

1. Connect the required trigger pin to the required source. Make sure that the voltage and current levels are compatible. 2. Navigate to the Triggers folder and enter the required trigger folder (Trigger 1, ..., Trigger 4). 3. Set Enable to Enabled. 4. Select the Action that the trigger will perform. Options are: Frequency Up, Frequency Down, Power Up, Power Down, RF Mute and Reboot. Frequency Up, Frequency Down, Power Up, Power Down and reboot will perform the action on falling edges of the signal on the trigger pin. RF Mute acts based on voltage levels. RF Mute will be engaged for as long as the trigger signal is pulled low and unmute when the signal is high. 5. If you require email alerts, set Send e-mail to Yes. Make sure e-mails are setup correctly.

(Refer to the e-mails section in this manual) 6. If Send e-mail is set to Yes, enter the (ON) Message that the trigger will send when fired. 8.4 Alarms Alarms on the V2 Transmitter indicate that a failure condition is met. They can be set to go off on Mod-

ulation level, Forward power, Reverse power and PLL lock fail. Upon triggering they will toggle the relevant pin on the rear alarms and trigger connector. They will also write a notification to the RS232, write to the system log and send an e-mail if required. Alarm pins can be configured as open-collector Outputs (when working as alarms) or as Analog outputs (for reporting system parameters as analog voltages). When used as alarms, 10 kOhm external pull-up resistors to 12 V should be placed on each pin to be able observe voltage changes in the alarm pins. To set up an Alarm pin as Alarm:

tion Bar and Transmitter Controls. Status Bar The Status Bar displays the current status of the Transmitter (Frequency, FWD power in Watts, REV power in Watts, peak Deviation in kHz). Alarms and Notifications The Alarms and Notifications Section displays the status of the alarms and the number of times that the alarms were fired in the last 24 hours. The Notifications section reports the num-

ber of emails sent by the unit within the last 24 hours. Navigation Bar This Bar Contains shortcuts that bring up the relevant windows connected to the feature:

43 A Status/Config This Brings up a box with all the relevant Status and configuration settings. There are: RF Status, Audio Status, Unit Status, Trigger Status, Trigger Config, Alarm Status, Alarm Con-

fig, Location, Contact, Date and Time, Uptime, Network, Web Portal, Telnet, RS232, Sys-

tem Details. B Audio Meters This Brings up a box with a graphical representation of the Audio Meters (Input, AGC, Limiters, Output, MPX). C Log Files This brings up a box with a collection of all the logs stored in the unit. The latest log (to-

days log) is displayed by default (TX-V2.log). Older logs can be selected from the list. If the unit has been switched on all the time, TX-V2.log.1 corresponds to yesterdays log, TX-V2.log.2 corresponds to the log written two days ago and so on. Note that if the unit is switched off, It will not write to the log and it will not create a new log file for the number of days it is off, so the older log files in this case will correspond to previous logs (written several days ago). Another way of accessing the logs, which may be useful in some cases where the log file contents need to be copied, is by browsing to a specific URL: http://IPAddress/TX-

V2.log For example (IPAddress = 192.168.5.32). For todays log:

Note that all the user settings will be lost and unit will load the default values for all the parameters. 61 Parameter Guide 9.1 RF Settings 9.1.1 Frequency 9 This sets the transmission frequency. The range for this parameter depends on the Band. For normal Band II transmitters the range is 87.5 MHz to 108 MHz. The normal step size is 50 kHz. Other frequency ranges and step sizes are also available on request. Please contact a sales representative for more information. 9.1.2 Power This sets the RF output level in watts. The range and the step size for this parameter depend on the model of the transmitter. The following table lists all the ranges for the different models in Watts:

Transmitter Model Minimum Power Maximum Power Step Size TX5 TX50 TX300 TX600 TX1000 TX1500 0.05 5.4 30.8 60.5 152 162 5.05 50.4 310.8 610.5 1102 1512 0.05 0.45 2.8 5.5 9.5 13.5 Note that when setting the power, the unit will automatically adjust the power output to reach the selected value. This may take a few seconds. During this time, the FWD power indi-

cator in the Status Box will flash to indicate that the unit is still adjusting to reach the selected power. 9.1.3 MPX Source This selects the source for the exciter. Options are Internal or External. Internal selects the in-

ternal generator, i.e. the output from the internal audio processor. This option must be se-

lected when the digital or analog inputs are used. External selects the MPX BNC input. This option must be selected when the transmitter is used with an external audio processor con-

nected to the MPX BNC input. 62 9.1.4 FSK (for translators in the USA) V2 Transmitters support automatic station identification using frequency shift keying (FSK). FSK sends a user defined ID once every hour using Morse code and shifting the carrier frequency up by 12.5kHz at 20 words per minute. FSK ID If enabled, the FSK ID will be sent once every hour. The required station ID must be entered in FSK ID (up to 16 characters). 9.1.5 RF Mute on Silence This selects the time after which the transmitters RF output will be muted if the transmitter is transmitting silence. Options are: off, 1 min, 10 min, 30 min and 1h. The transmitter identifies silence as a signal that produces a deviation of less than 30 kHz for the time period selected. The Status box will indicate that the output of the transmitter is muted:

9.1.6 RF Mute (Manual) This will manually mute the transmitter. The Status box will indicate that the output of the trans-

mitter is muted as shown in the picture above. 9.1.7 Power Scheduler This feature allows the unit to be configured for transmitting different RF power levels at dif-

ferent times of the day. The unit will normally transmit the signal at the power specified in RF Settings ) Power. If the power scheduler is disabled, the unit will keep transmitting at this power level all of the time. If the Power Scheduler is enabled, the unit will switch to the se-

lected scheduled power (Power Scheduler ) Power) when the time matches the Start Time and will return to normal power when the time matches Finish Time. This feature is intended to allow users to lower the power of their transmission at night time to reduce power consumption and avoid increasing the range of the transmission due to the change in atmospheric conditions. Please adhere to your licensing restrictions on power. 63 Enable Enables/disables Power Scheduling. Power Selects the power that the transmitter will produce during the scheduled interval. Start Time Selects the time at which the output power will change from normal power to scheduled power. Finish Time Selects the time at which the output power will change from scheduled power to normal power. Current Time Current time set in the unit. It can be modified to adjust the time in the Real Time Clock. 9.2 Audio Settings 9.2.1 MPX Source This is the same parameter as described in RF Settings. It has been placed in the Audio set-

tings menu for convenience of access. This selects the source for the exciter. Options are Internal or External. Internal selects the internal generator, i.e. the output from the internal audio processor. This option must be selected when the digital or analog inputs are used. Ex-

ternal selects the MPX BNC input. This option must be selected when the transmitter is used with an external audio processor connected to its MPX BNC input. 9.2.2 Audio Input Selects Digital or Analog as the audio input. These are the XLR connectors in the back panel. Note that the MPX Source parameter must be set to Internal to use the analog or digital in-

puts. 64 9.2.3 Processing Preset BW Broadcasts range of award winning DSPX audio processors has become known for their features, performance and value for money. Integrated within all V2 Transmitters is the 4-

band DSPXmini FM SE. This parameter selects the audio processing preset that the internal au-

dio processor will use. Options are: Bypass, AC, CHR, Tight, Hot, Loud, Smooth, Clean, Bright, RockNRoll, Low Bass, Urban, Talk, Classic Bright, Classic Bright2. Each processing preset pro-

vides a different overall sound. Try and experiment with different presets to find out which one is more suitable for your program material. Each processing preset is loaded live as the user scrolls through the menu allowing for easy comparison between them. A dedicated me-

tering screen (Audio Status) indicates the input levels, 4 band automatic gain control and limiters, along with audio level and MPX level meters. The Bypass preset can be used to by-

pass the internal processing. This is useful when using an external audio processor connected to the digital/analog inputs. In this case, an 8dBu signal on the back panel analogue input

(or -18DBFS on AES inputs) should be used to align to the safety clipper thresholds of the inter-

nal processor. Make sure Pre-emphasis is off when using the Bypass preset. Another option for bypassing the internal audio processor is to use the external MPX input. In this case, the MPX Source parameter must be set to External. 9.2.4 Pre-emphasis This parameter allows you to select the desired preemphasis characteristic (off, 50us or 75us). Make sure Pre-emphasis is Off when using an external processor connected to the analog or digital inputs and select Bypass as the Processing Preset. 9.3 Triggers V2 Transmitters have a comprehensive monitoring and control system consisting of 3 alarms and 4 trig-

gers. Pin 2 of the connector is hardwired to RF mute. Connecting this pin to ground will mute the transmit-

ger pin). Triggers are used to control certain param-

eters on the V2 Transmitter using the relevant pins on the rear alarms and triggers connector. To fire a trig-

ger, the pin must be pulled low. 9.3.1 Enable Enables/disables the trigger. 65 Figure 9.1: Alarms and Triggers Port 9.3.2 Action Selects what the trigger will do when it is detected. Options are: Frequency Up, Frequency Down, Power Up, Power Down, RF Mute, Switch to Int MPX, Switch to Ext MPX, Switch to Mono, Switch to Stereo, Reboot. Frequency Up, Frequency Down, Power Up, Power Down and Re-

boot will perform the action on falling edges of the signal at the trigger pin. RF Mute acts based on voltage levels. RF Mute will be engaged for as long as the trigger signal is pulled low and unmute when the signal is high. Note that the RFMute pin (Pin 2) mutes the unit unconditionally. (Triggers set to RFMute will not be able to unmute the unit if this pin is connected to ground). 9.3.3 Send e-mail Selects if an e-mail will be sent when the trigger is fired. Make sure that the unit is connected to the network and that E-mails have been set up correctly System ) E-Mail to use this fea-

ture. 9.3.4 (ON) Message Sets the message that will be sent when the Trigger changes to ON. This parameter accepts text up to 300 characters. Sample e-mail:

Trigger 1 transitioned to ON. Equipment: TX-V2, Serial Number #8790 Location:

Local IP Address: 192.168.5.31 If you require off-air emergency technical support, please contact the BW Broadcast 24/7 support team:

International Phone: +44 208 2530295 US Toll Free: 1-888-233-1663 Email: support@bwbroadcast.com Please note that this is an automatic email alert generated by a BW Broadcast TX-V2. To pre-

vent further emails please clear the cause of the alarm or turn off alarm emails on the TX-V2s control system. 66 9.4 Alarms Alarms on the V2 Transmitter are used to indicate that a failure condition is met. They can be set to trigger on Modulation level, Forward power, Reverse power and PLL lock fail. Upon triggering they will toggle the relevant pin on the rear alarms and trigger connec-

tor. They will also write a notification to the RS232, write to the system log and send an e-mail if required. Alarm pins can be configured as open-collector Out-

puts (when working as alarms) or as Analogue out-

puts (for reporting system parameters as analogue voltages). When used as alarms (open-collector out-

puts), 10 kOhm external pull-up resistors to 12 V should be placed on each pin to be able observe voltage changes in the alarm pins. 9.4.1 Type Figure 9.2: Alarms and Triggers Port Alarms can be configured as either alarms (open collector pins that will show 0 volts or open collector depending on the result of the condition tested); or as analogue outputs, which will report a parameter as an analogue voltage. The parameter Type allows this selection by pro-

viding the options Alarm and Analogue Out. Alarms pins as Alarms A Type When the alarm Type is set to be Alarm, the system will look at the specified failure con-

dition in the Source parameter and trigger the alarm if the condition has been present for longer than the specified On Delay time or release the alarm if the condition has not been present for longer than the specified Off Delay time. B Source Selects the failure condition that alarm will watch for. Options are: Mod Level <, Mod Level >, Fwd Power <, Fwd Power >, Rev Power <, Rev Power > and PLL Lock Fail.

- Mod Level observes conditions in the modulation (or deviation) level of the transmitted signal.

- Fwd power observes conditions in the Forward power

- Rev power observes conditions in the Reverse power

- PLL Lock Fail observes if the PLL lock has failed and the system cannot tune to the re-

quired frequency. 67 C Threshold Selects the threshold value that will be used to detect the error condition. This doesnt apply to the PLL Lock Fail alarm. D Pin Polarity Selects whether the alarm output pin is active high or active low. When +ve is selected, the output will act as a 430 Ohm resistor to ground when the alarm is active and as a 100 KOhm resistor to ground when the alarm is not active and vice-versa if -ve is selected. E On Delay Selects how long the failure condition must be present for before the alarm is fired. This can be set from 2 seconds to 600 seconds. F Off Delay Selects how long the failure condition must have stopped for before the alarm is re-

leased. This can be set from 2 seconds to 600 seconds. G Send e-mail Selects if an e-mail will be sent when the alarm state changes. Ensure that the unit is connected to the network and that E-mails have been set up correctly System ) E-

Mail to use this feature. Examples of alarm uses and set-up Example 1: We would like the system to fire alarm A with normal polarity when the forward power has dropped below 40.5 watts for longer than 20 seconds. We would like the alarm to be release if the power rises above 40.5 watts for longer than 10 seconds. Setup:

1. Navigate to Alarms ) Alarm A 2. Select Type = Alarm 3. Select Source = Fwd Power <

4. Set Fwd Power Threshold to 40.5W 5. Set Pin Polarity to +ve 6. Set On Delay to 20s 7. Set Off Delay to 10s 8. Set Send e-mail as required. Make sure emails are set up correctly if the feature is en-

abled (consult the relevant section in this manual) 68 Example 2: We would like the system to fire alarm B with inverted polarity when the modula-

tion level has dropped below 30 kHz for longer than 15 seconds and release alarm B when the modulation level rises above that level for 5 seconds. This is a way of detecting that silence being transmitted. Setup:

1. Navigate to Alarms ) Alarm B 2. Select Type = Alarm 3. Select Source = Mod Level <

4. Set Modulation Threshold to 30kHz 5. Set Pin Polarity to -ve 6. Set On Delay to 15s 7. Set Off Delay to 5s 8. Set Send e-mail as required. Make sure emails are set up correctly if the feature is en-

abled (consult the relevant section in this manual) Example 3: We would like the system to fire alarm C with normal polarity when the reverse power increases above 10.35 watts for longer than 20 seconds. We would like the alarm to be release if the reverse power decreases below 10.35 watts for longer than 10 seconds. Setup:

1. Navigate to Alarms ) Alarm C 2. Select Type = Alarm 3. Select Source = Rev Power >

4. Set Fwd Power Threshold to 10.35W 5. Set Pin Polarity to +ve 6. Set On Delay to 20s 7. Set Off Delay to 10s 8. Set Send e-mail as required. Make sure emails are set up correctly if the feature is en-

abled (consult the relevant section in this manual) 69 Alarms pins as Analogue Outputs When the alarm Type is set to be Analog Out, the alarm pin will report the status parameter selected in Source as an analogue voltage on the alarms pins. This setup is typically used to connect the unit to remote control equipment (also known as telemetry interfaces). The Souce can be set to any of the following parameters: Fwd Power, Rev Power, PA Volts, Aux Volts, Peak Modulation, PA Temp, RF Mute. Use the following equation to translate voltage levels into parameter values:

CurrentValue =

VOut 1.2 NominalValue 5

(9.1) Where:

VOut is the voltage on the pin in Volts. NominalValue is defined in the following table:

Parameter FWD Power REV Power PA Volts Aux Volts Peak Mod PA Temp

*RF Mute NominalValue For TX50 = 50Watts For TX300 = 300 Watts

... Same as FWD Power For TX5 = 15 Volts For TX25 and TX50 = 24 Volts For TX300 or greater = 48Volts 15 Volts 100 kHz 100C

* This parameter does not use the above equation. Its representation is:

If RF Mute = On, VOut = 5 Volts If RF Mute = Off, VOut = 0 Volts For example, if the measured Voltage level is 4.166 Volts on a TX50 reporting Forward Power, the actual current value will be:

Power (watts)= (4.166*1.2*50)/5 = 49.992 Watts (Approx. 50 Watts) 9.5 System 9.5.1 Date System Date. This is backed up by an internal battery. 70 9.5.2 Time System Time.

Please ensure that you are using the correct mains voltage as specified in the transmit-

ters technical manual.

On the menu, check that the unit is not set to RF mute or that the alarm ports at the back are not set to RF mute.

If the unit has a slide-in power supply, please check that the power supply is pushed in correctly at the back of the unit.

Check that the set power on the menu to the desired RF power. (BW Broadcast trans-

mitters are set to minimum output power when they leave the factory. This can be ad-

justed on the front panel via RF settings ) Power. You may want to increase this pa-

rameter to the desired power.

Check that the Power Scheduler feature is disabled (if not required). Or set-up correctly if required. Check that the System time is correct. All these settings are contained in the folder: RF Settings ) Power Scheduler VSWR fault light is on

The front panel VSWR fault LED illuminates when there is high reverse RF power from the antenna. This is usually caused by factors external to the transmitter. In this case, please check the antenna, cable and connectors, as well as the antenna itself. I am not able to change any settings on the unit (Passcode)

This usually means that the front panel screen has been locked with a 4 digit passcode. The original 4 digit code has to be entered before any settings can be changed. Once the correct code is inserted, press the middle button on the right hand side to confirm the passcode. I have no modulation

Please check that the correct input source has been selected on the front panel con-

troller Audio Settings ) MPX Source. If you are using the digital or analog inputs (XLR connectors), this option must be set to Internal. If you are using the external MPX BNC input, this option must be set to External. 79 Modulation level is too low

Most professional signal sources will be able to drive BW Broadcast transmitters to full de-

viation. Some battery-powered or weaker sources, such as PC sound cards, may not be able to provide enough drive to achieve full modulation in the transmitter. If using the XLR inputs and the internal audio processor then we advise that you check the meters screen in the Front Panel (Please press the bottom button on the right until meters screen appears). Assuming that the transmitter preset is not set to Bypass, then you should be able to observe movement on the meters labeled LIM and AGC. If you they do not move, then you should increase the level in your audio source so that they do. If you are not able to increase your audio level from your external audio source you can increase it by adjusting the level pot located on the left hand side of the 2 BNCs on the rear panel. I am using the MPX input and have strange sound issues

Ensure that Audio Settings ) MPX Source is set to External.

Leaving it switched to Internal will feed the internal stereo generator audio into the ex-

citer. This will result in distortion and interference with the signal you are feeding from your external composite source connected to the MPX input of the transmitter. Transmitter occasionally changes RF power

Please check tat the Power Scheduler feature is not enabled (RF Settings ) Power Scheduler). If this feature is required, ensure it is correctly set-up and the time in the sys-

tem is correct. Please refer to Operation Guide ) RF Settings ) Power Scheduler on this manual to properly configure this feature. Temp fault light is on

Please ensure that the fans are running and not obstructed and the transmitter is in a well ventilated area. Other Issues If your issue is not covered in this guide or you have tried the above and still having trouble, you can contact our 24 Hour Support Team:

tions by reducing the output power. The reduction will start at 71 C. At 81 C, the power will be reduced to 50% and at 85 C to around 6%. 11.1.7 VSWR Protection The VSWR protection circuitry will protect the unit against high VSWR conditions by reduc-

ing the output power. This protection will reduce the output power to 50% when the reverse power is 10% of the forward power. 83 11.2 Model-Specific Specifications 11.2.1 TX5 V2 485mm x 350mm x 45mm 2kg 100 - 265 VAC IEC Size Weight Votlage input Power connector Switched mode approvals UL / TUV / CE Power Consumption Power Power Supply Connector Approvals:
