If such noise occurs, adjust the output level of the receiver so that highest sound pressure level going into the microphone transmitter causes no input overload in the mixer, but permits the mixer level control to operate in the normal range (not too high and not too low). This provides the optimal signal-to-noise for the entire system.

the unit is not to be used for a long period as the transmitters draw a tiny residual current to maintain the programmed settings, even when turned off. Also, since batteries installed for a long time can sometimes corrode and/or leak, causing damage, it is generally recommended that batteries be removed whenever the transmitters are not being used.

when an electric guitar with dirty pots or connections is used with a wireless system. Therefore, the supplied capacitor provides rst-order ltering of the RF signal from the cord into the guitar and eliminates virtually all scratchy noises. Should your equipment still produce scratchy noise, we suggest these steps to eliminate prob-

lems:

1) Make sure all guitar volume and tone pots are clean and all contacts are solid. This is very important. 2) Solder a 47pF capacitor across the pot to ground terminal of the guitars volume and tone pots to provide extra ltering. 18 powered on and red for low battery needing replacement lapel mic (LT), Headmic (LT/HM), or instrument (GT) cable 38.

SYSTEM OPERATION 7. CAUTIONS AND TROUBLESHOOTING U-800 RECEIVER Button Function The POWER ON Button (1) is used to power receiver ON or OFF. When the power button is pressed, the POWER LED (2) and the white backlight on the LCD DISPLAY (5) will light up indicating the receiver is ready. Press the Power button again to turn off the receiver. The power LED and the backlight on the LCD will be off indicating the receiver is off. At power-off the U-800 receiver will store the last settings entered and re-display them at power-on. It can be reprogrammed to any new Group/Channel, or Mute level. The default factory setting is Group 11, Channel 01 and Mute 0 on the rst LCD menu screen. The UP BUTTON (16) is pressed one step at a time to SCAN, IR or to increase GROUP, CHANNEL, MUTE by one level each time The DOWN BUTTON (17) is pressed one step at a time to decrease GROUP, CHANNEL, MUTE by one level each time The MENU BUTTON (18) is pressed one step at a time for Auto Scan Frequency or to Automatic GR/CH ASC Sync, or if pressed repeatedly the LCD DISPLAY (5) menu will cycle through the following screens. Press the MENU BUTTON (18) and the UP BUTTON (16) at the same time to lock or unlock the keyboard/buttons. During manual programming, press the MENU BUTTON (18) to conrm the selection and advance to the next menu before the Auto Programming Function takes over after 5 sec. Feedback Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume, transmitter location and speaker placement. Please also note the pickup pattern characteristics of the microphone selected. Unidirectional microphones are more resistant to feedback. However, they pick up sound sources best that are directly in front of the microphone. Also, mics that are farther from the sound source (such as a handheld) require more acoustic gain and thus are also more prone to feedback than close-source mics. No or Low Audio If you are not getting audio through the system, carefully re-check all setups. Especially note that the receiver and transmitter must be set to operate on the same RF channel. Also conrm that the transmitters AUDIO MUTE (36, 40) is not in the OFF position. The receivers UNBALANCED LINE OUT (19) is adjustable so make sure the VOLUME CONTROL (21) is set properly. RF Interference and Finding Open Channels The FCC mandates the following information be provided to all end users of this equipment:

Consumer Alert Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50mW); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit www.fcc.gov/cgb/consumerfacts/wirelessmic_factsheet.html. Rack Mounting the Receiver There are 2 options available for rack mounting the U-800 receiver: singly or side by-side with another U-800 receiver. a. Single mounting: Remove the receiver SIDE MOUNT CLIP (24) from each side of the receiver (as shown) and slide in the optional ERM-12 RACK EARS (25). b. Side-by-side double mounting: After removing the SIDE MOUNT CLIPS (24) and attach the ERM-22 RACK EARS (27) as shown.

(Note: Do not mount the receiver in a rack directly above an amplier or other source of high heat this could degrade the performance of the U-800. Always ensure ad-

equate airow and heat dissipation in any rack conguration.) from both U-800 receivers join the two receivers with the EJC-3 JOINING CLIP (26) If you encounter slight receiving interference when the transmitter is far from the receiver (from other than an operating TV station on the same frequency), it can often be overcome by adjusting the receivers MUTE LEVEL/SQUELCH (13) Adjusting the Mute Level / RFSquelch. If receiving interference on a selected channel with the transmitter off, or if you en-

Selecting Group/Channel, IR Programming and Simultaneous Multichannel Operation open channels. 8 17 Receiver/Transmitter ASC IR Sync Manual Programming To manually program the pre-selected Group/Channel (frequency) from the receiver to the transmitter, place the transmitters IR RECEPTOR SENSOR WINDOW (37, 44) 6-12 away from the receivers IR WINDOW (4). Press the MENU BUTTON

(18) four times to the IR Screen Display and then press the UP BUTTON (16) to start IR programming. The ashing IR INDICATOR (10) icon indicates IR transmission is in progress. When the synchronization is completed successfully (usually in less than 2 seconds), the RF INDICATOR (8) and the diversity A or B INDICATOR

(9) on the receiver will display, indicating that the IR linking is completed. The LCD DISPLAY SCREEN (5) will show the selected channel. If the UP button is not pressed during the two seconds of active data transfer, the IR INDICATOR (10) will not ash, the LCD Display will revert to the main menu, the receiver will not link to the transmitter, and the transmitters previously programmed channel remains unchanged. Instructions for Setup of Simultaneous Multichannel Operation This U-800 receiver is capable of nding an open channel with its autoscan capability. This built-in feature is a quick, convenient way to set up many wireless systems at the same location for simultaneous multichannel operation. If you are using multiple transmitters at the same location, set up the rst transmitter and leave it ON and keep 10 feet away from the receivers and 1 foot away from transmitter to transmitter. This avoids possible duplicate selection of the same channel as already se-

lected for the rst receiver. Then start the autoscan function on the second receiver. Repeat this procedure for all receiver/transmitters to be used in your system. Finally with all the transmitters ON, perform a range walk test in the location these systems will be used in to check for potential crosstalk interference in this application. If you are not satised with any of the channels scanned, repeat the autoscan procedure for that receiver again anytime for nding another free channel. This process can be simplied if you select channels within Factory SELECTED Groups 11 to1A, as the channels within those groups are mutually compatible (unless there is outside interference on any of the selected frequencies). If there is any such interference in your location, select as many channels as you can using these 10 groups and then select additional open channels as needed (depending on number of systems to be operated simultaneously) from Groups 1B to 1F. As noted above all these groups will retain in memory the previously selected channels for that group for easy setup subsequently in that same location. Powering the Receiver Plug the AC/DC ADAPTER (23) provided into the DC INPUT JACK (20) on the back of the receiver. Then plug the power supply into an AC outlet. (Note:

Any 22V DC source with 400mA capability can also be used.) Press the POWER SWITCH (1) once to turn on the receiver. The POWER ON LED (2) and the LCD DISPLAY (5) will now light and the receiver is operational. Adjusting Antennas The U-800 has two permanently attached, exible-elbow ANTENNAS (3) for diver-

sityreception. Unfold and rotate these antennas to operate the receiver. The optimal positions of the antennas are ared 45 out from the receiver sides and 90 from each other. For maximum range, it is always best to maintain a line-of-sight (no obstructions) between the receiver antennas and the transmitter at all times whenever possible. Adjusting the Mute Level/ RF Squelch The MUTE LEVEL/RF SQUELCH (13) can be changed anytime during the main screen display to quiet the receiver in high noise environment condition. The control ranges are from level 0 to level 5. The level should be adjusted to a lower number for the minimum RF squelch setting at which the RF INDICATOR (8) will remain on while your transmitter is in normal use, up to the maximum operating range anticipated in use for your application. However, in areas of high RF activity, the squelch control may need to be adjusted to a higher number. If the transmitter is off and the receivers signal RF INDICATOR (8) or the diversity A or B INDICATOR (9) ickers or stays on continuously, the squelch should be adjusted to a higher number to stop the ickering. Be careful not to select too high a number setting as this may reduce the operating range to below what is needed. A range walk test will help in selecting the proper level. If the range is not critical, note that a higher level (maximum squelch) setting will also yield a quieter mute function, which might be desired in certain applications. The squelch level is factory preset at maximum sensitivity and operating range (i.e. level 0 for minimum squelch levelmaximum usable range). Note: For easier intuitive operation, the MIN and MAX indications for this control refer to the minimum and maximum operating range settings, not to the actual mute levels selected, which are the opposite as per above. Keyboard/Buttons Lock Function Use keyboard/Buttons Lock Function to lock or unlock the receiver controls, preventing accidental adjustment during use: You can push and hold MENU BUTTON (18), then push UP BUTTON (16) to lock; push and hold MENU BUTTON (18), then push UP BUTTON (16) again to unlock. The Keyboard/Buttons must be unlocked before you can make a selection: AUTO SCAN, Group/Channel or MUTE levels. 16 9 Audio Level and Peak LED Indicator The U-800 receiver has a 5 bar AF LCD (7) display that typically shows a few bars indicating normal level audio signal from the transmitter. Occasional ickering of the fth AF LCD (peak level) on loud inputs to the transmitter is normal. If the AF LCD lights up full bars continuously decrease the input audio level to the transmitter or overload distortion may result. Connecting the Audio Output The U-800 receiver has two type of outputs available, an adjustable level UNBALANCED LINE OUT (19) and a xed level MIC out BALANCED MIC OUT XLR JACK (22). The unbalanced line out is controlled by the VOLUME CONTROL (21). For unbalanced line output connection, plug an audio cable with a mono

(Tip/Sleeve) plug into the Unbalanced Line Out jack and plug the other end into your mixing board or amplier. Adjusting the Volume control will increase or decrease the audio level at the Unbalanced Line Out only.

(Note: When using the UB-800 instrument transmitter system, connect the Unbalanced Line Out directly to your instrument amp or preamp. At maximum receiver volume setting, the system output is approximately +4dB higher than a direct cord-to-amp connection.) For balanced Output connection, plug an audio cable with an XLR connector into the Balanced Mic Out XLR Jack socket and plug the other end into your mixing board or amplier and control the audio levels from there. Both the Unbalanced Line Out and the XLR Balanced Mic Out can be used at the same time to connect to your mixing board, effect, or amplier. Please follow below drawing for the audio cable/

connector wiring. F-XLR 1/4 Plug SLEEVE TIP Pin 2: +

Your U-800 receiver is now operational and ready to use. Proceed to the following instructions for the UH-800 handheld microphone transmitter or UB-800 bodypack transmitter included with your system. Note: As when making any connection, make sure the amplier or mixing board volume is at the minimum level before plugging in the receiver to avoid possible sound system damage. Note: Only one transmitter can be used with one receiver. It is not possible to use two transmitters on the same frequency and mix the output of these transmitters into one wireless receiver. after receiver is powered off. This facilitates easy setup by enabling quick selection of stored channels for any group, i.e, selecting any group will automatically display the last channel selected for that group. See section 11. U-800 Frequency Lists for available channels in each group. The previous group and channel used is stored in memory automatically when receiver and transmitter are turned off after operation. Selecting a different group on the receiver in subsequent use will display a differ-

ent channel as previously selected for that group, however, the transmitter will need again to be synced to that new frequency to complete the system setup for operation. Receiver ASC/IR Sync GR/CH (Frequency) If different frequencies than previously stored in both the receiver and transmitter memories are needed, there are three ways to program the receiver and then sync

Use the UP/DOWN Buttons to change the channels (frequencies) that are available in each group. [Note: for Group11 to 1A, the CH (12) display will in-

dicate the channel number chosen, and for Group 1B to 1F only the letter U and the frequency chosen will be displayed. See section 11. U-800 Frequency Lists for available channels in each group]. After nishing channel selection, press the MENU BUTTON once or wait a few seconds for IR MENU, and then press UP BUTTON to start IR programming. This completes the GP/CH (frequency) programming. The next section outlines the procedure for syncing the receivers programmed channel to the transmitter. 10 15 Connecting Input Audio Source Lapel/Head Mic Uses (UB-800 LT/HM) The mini 3.5mm locking INPUT JACK (39) is for connecting the audio input from a lavaliere/lapel Mic (LT), a Head Mic (HM), or an instrument (GT) cable, depending on which transmitter version is being used. Secure the connection to the cable by tighten-

ing the cable mini plugs outer ring counterclockwise. When ready to play, slide the AUDIO MUTE ON/OFF SWITCH (40) to the ON position to un-mute the audio. Adjust the INPUT VOLUME LEVEL (43) on the transmitter for suitable level. Instrument Use (UB-800 GT) Secure the connection of the GT (instrument) cable by tightening the mini plug outer ring counterclockwise onto the 3.5mm locking INPUT JACK (39). When ready to play, slide the AUDIO MUTE ON/OFF SWITCH (40) to the ON position to un-mute the audio. Adjust the volume on the receiver for one-to-one unity gain with a hardwired cord or select up to an added 4-5dB boost by adjusting the receiver volume to maximum for normal use with guitars and bass guitars. Note: The audio level should be adjusted on the instrument as when using a hardwired cord. Programming the UB-800 to the Selected Group/Channel (frequency) The transmitter must be programmed to the same frequency as selected for the receiver via automatic synchronization using the IR ASC Sync function. It cannot be pro-

grammed on the transmitter itself. See next section 6. Selecting Group/Channel, IR Programming and Simultaneous Multichannel Operation. 6. SELECTING GROUP/CHANNEL, IR PROGRAMMING AND SIMULTANEOUS MULTICHANNEL OPERATION Note: Note: The transmitter should be turned ON and ready for the IR communica-

tions with the receiver IR receptor for the following process. Note: If no button is pressed within the ve seconds period during a selection, the program is terminated and the process needs to be repeated. Note: For normal operation, the transmitter should have the same channel as dis-

played on the receiver. Choosing Group/Channel for the System The receiver offers a choice of 15 groups: 10 that are Factory PRESET (Group 11 to 1A) and 5 that are User SELECTABLE (Group 1B to 1F). If the Factory PRESET Group mode is chosen, only a limited numbers of channels are available in these groups. For most convenient setup, each of these groups offers from 3 to 14 channels

(depending on group selected) to choose from that are factory preset for simultaneous multichannel operation compatibility and are retained in memory after the receiver is powered off. For the User SELECTABLE Group 1B-1F mode, a letter U will lit up on the LCD DISPLAY (5) instead of the CHANNEL (12) number as in the Factory PRESET Groups. Each User SELECTABLE Group has 800 channels to choose from either by manually selecting a channel or using the Auto-Scan in 1MHz segment increments at a time within the frequency band and they are retained in memory Programming the U-800 to the Selected Group/Channel (frequency) The Receiver must be programmed for a Group/Channel (frequency) rst then auto-

matic synchronization using the IR ASC Sync function to the transmitter. For system set up procedures, see next section 6. Selecting Group/Channel, IR Pro-

gramming and Simultaneous Multichannel Operation UH-800 Handheld Microphone Transmitter (HT) Setting up the UH-800 Transmitter The UH-800 requires two AA alkaline or NiMH batteries to operate (do not mix types). Installing batteries by unscrewing counterclockwise the BATTERY COVER

(29) and slide down, exposing the BATTERY COMPACTMENT (32). Insert two fresh AA BATTERIES (31), observing the correct polarity as marked, and screw the cover back on to the microphone. Make sure the cover is screwed clockwise complete-

ly. Fresh alkaline batteries can last up to 10 hours in use, but in order to ensure optimum performance, it is recommended that you replace the batteries after every 6-8 hours of use. Powering the UH-800 Transmitter On/Off Turn on the UH-800 by sliding the AUDIO SWITCH (36) to the OFF position rst. Then slide the POWER SWITCH (35) to the ON position. The POWER ON LED

(33) will stay on, indicating that the transmitter is now on. The BATTERY LED (34) will stay off, indicating usable battery strength. In the case of a dead or low battery, the low battery LED will light red continuously, indicating that the batteries should be replaced with fresh ones. To preserve battery life, turn the transmitter off when not in use. To turn the transmitter off, slide the RF POWER (35) switch to the OFF position. The POWER ON LED

(33) is not lit up, indicating the unit is off. The MUTE ICON (6) on the receiver should be on, muting the audio out. At power off the transmitter will store the last settings entered and re-display them at the next power on. The default factory setting is Group 11, Channel 01. For optimum performance, an AUDIO INPUT LEVEL (30) is provided. Adjust the gain by turning the control with a small screwdriver. It is recommended that the level be set at about 1/2 maximum. Experiment and set for maximum possible gain without audible distortion on the high level peaks. (Note: Turning down the gain too much can compromise the signal-to-noise and it is not recommended.) The microphone is now ready to use. The diversity A/B INDICATORS (9) on the U-800 receiver should now be on, indicating a received signal from the transmitter. When ready to speak, slide the AUDIO MUTE (36) to the ON position. The MUTE ICON (6) on receiver should be off. Adjust the volume of the receiver as per the Au-

dio Output Microphone Connection section of the above U-800 receiver instructions. 14 11 Note: The windscreen of the UH-800 functions as a built-in antenna. For proper operation, never remove the windscreen during use, or exchange with another type. For optimum range maintain line-of-sight between the transmitter and the receiver whenever possible. Holding the microphone tightly, bridging across the windscreen and Mic tube, will also lessen range. Hold by the Mic tube housing only for optimum operation. Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that acoustic feedback (howling or screeching) will be avoided. Operating the UH-800 Handheld Transmitter The RF POWER (35) and the AUDIO MUTE (36) switches have two positions for power ON/OFF and audio mute ON/OFF respectively. During normal operation with the unit powered on standby, slide the RF POWER (35) switch to the ON posi-

tion. You will feel a slight click indicating the ON position is selected. The receivers RF Indicator (8) and diversity A/B INDICATOR (9) should now be on, indicating a received RF signal from the transmitter. When ready to transmit audio, slide the AUDIO MUTE (36) to ON to un-mute. To mute, slide the switch to OFF again. Adjust the volume of the receiver per the previous section, Connecting the Audio Output. Note: Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume, transmitter location and speaker placement. Programming the UB-800 to the Selected Group/Channel (frequency) The transmitter must be programmed to the same frequency as selected for the receiver via automatic synchronization using the IR ASC Sync function. It can not be programmed on the transmitter itself. See in next section 6. Selecting Group/

Channel, IR Programming and Simultaneous Multichannel Opera-

tion. UB-800 Bodypack Microphone Transmitter (LT, HM or GT) Setting up the UB-800 Transmitter The UH-800 requires two AAA alkaline or NiMH batteries to operate (do not mix types). To install the batteries, lift the LATCHING BATTERY DOOR (46) and open up, exposing the BATTERY COMPARTMENT (45). Insert two fresh AAA batteries according to the polarity indicated on the transmitter body. Close the battery cover back onto the microphone, making sure it is secure. Fresh alkaline batteries can provide up to 8 hours of operation, but in order to ensure optimal performance it is recommended that the batteries be replaced after 4-6 hours of use or as indicated necessary by the BATTERY STATUS LED (41) lit RED. Powering the UB-800 Transmitter On/Off Turn on the UB-800 by sliding the AUDIO MUTE (40) to the OFF position rst. Then slide the POWER ON/OFF (42) to the ON position. The BATTERY STATUS LED (41) will stay on GREEN and the transmitter is now on, indicating usable battery strength. In the case of a dead or low battery, the LEDs will not go on at all or the BATTERY STATUS LED (41) will stay on RED continuously, indicating that the batteries should be replaced with fresh ones. To preserve battery life, turn the transmitter off when not in use. To turn the transmitter off, slide the POWER ON/OFF (42) switch to the OFF position. The BATTERY STATUS LED (41) is not lit up, indicating the unit is off. The MUTE ICON (6) on receiver should be on, muting the audio out. At power off the transmitter will store the last settings entered and re-display them at the next power on. The default factory setting is Group 11, Channel 01. For optimum performance, an INPUT VOLUME LEVEL (43) is provided (for LT/

HM input mode operation only). Adjust the gain by turning the control with a small screwdriver. It is recommended that the level be set at about 1/2 maximum. Experiment and set for maximum possible gain without audible distortion on the high level peaks. (Note: Turning down the gain too much can compromise the signal-to-noise and it is not recommended.) The microphone is now ready to use. The diversity A or B INDICATORS (9) on the U-800 receiver should now be lit, indicating a received signal from the transmitter. When ready to speak, slide the AUDIO MUTE ON/OFF SWITCH (40) to the ON position. The MUTE ICON (6) on receiver should be off. Adjust the volume of the receiver as per the Audio Output Microphone Connection section of the above U-800 receiver instructions. Note: The transmitter has a removable ANTENNA (38). For best operating range, it should be attached (screwed on tightly counterclockwise, or exchange with another type.). For best transmitting power during use, make sure it is not blocked. For optimum range maintain line-of-sight (no obstructions) between the transmitter and the receiver whenever possible. A walk test before use will determine the operating range in your application. Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that acoustic feedback (howling or screeching) will be avoided. Operating the UB-800 Transmitter The POWER ON/OFF SWITCH (42) and the AUDIO MUTE ON/OFF SWITCH (41) switches have two positions for power ON/OFF and audio mute ON/Standby respectively. During normal operation with the unit powered on standby, slide the RF POWER (35) switch to the ON position. You will feel a slight click indicating the ON position is selected. The receivers RF INDICATOR (8) and diversity A/B INDICATOR (9) should now be on, indicating a received RF signal from the transmitter. When ready to transmit audio, slide the AUDIO MUTE (36) to ON to un-mute. To mute, slide the switch to OFF again. Adjust the volume of the receiver per the previous section, Connecting the Audio Output. Note: Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume, transmitter location and speaker placement. 12 13 c o n n e c t e d
