promise applications where performance and security are the highest priority. A completely new digital architecture was developed for the DSW wireless system. Extended operating range rivals the best analog and Digital Hybrid Wire-

less systems, with remarkable audio quality and only 2.5 ms of latency. The system operates on standard UHF FCC Part 74 frequencies (TV channel band). 256-bit encryption is applied to the transmitted signal stream for security against eavesdropping. The algo-

rithm conforms to the AES 256-CTR standard. DR Modular Receiver The DR receiver is a 1RU modular, six-channel design with a host mainframe that contains the DSP, micro-

processor, antenna multicoupler and control interface. Receiver modules are installed on either side of the mainframe. No tools are required to remove and install the receiver modules. Each module will tune across a 25.6 MHz range. Antenna ports on the rear panel accept input from remote antennas, with a loop-thru output to another mainframe. A high quality internal multicoupler distrib-

utes the RF signal to the receiver modules. For rack mount installations, a kit is available to mount antenna inputs (BNC connectors) on the receiver front panel using a coaxial cable routed through the receiver chassis to the rear panel connections. DB Belt Pack Transmitter The DB belt pack transmitter is encased in a solid machined aluminum housing with a membrane switch panel and backlit LCD interface. The servo bias input circuitry will work with a wide variety of microphones and line level sources, Input gain is adjustable over a wide range in 1 dB steps to optimize the signal to noise ratio and dynamics of the audio. The transmitter tunes across the entire frequency range of the DSW system, from 470 MHz to 691 MHz.

Antenna Cable Front Panel Pass-thru A coaxial cable can be routed from the rear panel BNC connectors to BNC connectors on the left and right side of the front panel. The coaxial cable is routed through the inside of the receiver chassis. Power Supply The receiver is powered from an external power sup-

ply, 10 18 VDC, 4A. Rio Rancho, NM 5 DSW Digital Wireless System Hardware Installation Receiver Modules The DR mainframe/host assembly is a wideband design that coves the entire available frequency range. Individual receiver modules are available in 25.6 MHz frequency blocks. Any module can be installed in any of the six mainframe positions without regard to the frequency tuning range. Module positions correspond to the rear panel audio outputs as shown here. Front panel 4 5 6 3 2 1 Installing Receiver Modules 1. Turn the mainframe power off. The receiver modules interface with the main as-

sembly through multi-pin connectors on either side of the chassis. Insert the module straight down and then slide it toward the main housing to insert the connector pins. The module should sit ush against the side of the housing. Antenna Connections Connect the antennas or coaxial cables to the antenna input connectors labeled IN on the rear panel. Note: The frequency bandwidth of the antennas must cover the range of the modules in use. For multiple unit installations, a loop thru is available to feed two or three receivers from a single antenna pair. Connect coaxial cables from the multicoupler out-

puts on the rst receiver to the antenna inputs on the next receiver in the stack. ANT PWR ANT PWR ANT PWR AES 5 & 6 AES 5 & 6 AES 5 & 6 AES WORD CLOCK AES WORD CLOCK AES WORD CLOCK AES 3 & 4 AES 1 & 2 AES 3 & 4 AES 1 & 2

LOCK PANEL BACK LIGHT ANTENNA POWER NETWORK SETUP RS232 SETUP COMMAND VIEW SYSTEM INFO PROG SWITCH AUTO ON TX PANEL LOCK BATT TIMER TX BACKLIGHT AUDIO OUTPUT MODULE POWER NETWORK SETUP congures the IP address and other credentials for network connections through the ethernet port. RS232 SETUP sets the baud rate of the RS232 port. COMMAND VIEW is used to send hand typed commands from a computer directly to a connected receiver, and display the response that comes back on the computer screen. It is helpful for testing commands during development of programs for 3rd party controllers, and to send a batch of commands from a le to congure or test the receiver. SYSTEM INFO displays the receiver serial number, rmware version and hardware version. Active Alerts will also appear on the list, if there are any. TX MENU Transmitters can be congured in the receiver and the settings can then be sent to the transmitter via the USB cable. SEND SETTINGS transfers the settings for the transmitter conguration that are stored in the receiver to the attached transmitter. The transfer is made via the key cable. TX BATTERY is used to make the battery status monitor more accurate, since the behavior of alkaline and lithium batteries is different across their life during use. TX AUDIO GAIN adjusts the transmitter input gain to optimize the signal to noise ratio and dynamic range of the system with voices or signal sources, different microphones and microphone positions. Rio Rancho, NM 11 SMART NR (smart noise reduction) allows the selection of the noise reduction mode on each channel. Options include NORMAL, FULL and OFF. PHASE inverts the polarity of the analog audio outputs on the receiver. AUDIO OUTPUT selects analog or AES digital modes for the receiver outputs. Adja-

cent modules are paired in the selection. MODULE POWER turns each receiver module on or off. DSW Digital Wireless System

(TX MENU contd) LF ROLLOFF adjusts the point at which the low frequency audio in the transmitter begins to roll off. This knee can be set at 35, 50, 70, 100, 120 or 150 Hz. TX PHASE reverses the polarity of the audio signal in the transmitter to match other microphones in the system that vary with different microphone types and connector wiring. NOTE: The audio polarity on each output channel on the receiver can also be reversed in the RX MENU. PROG SWITCH congures the function of the switch located on the outside of the housing on the transmitter. The switch can be cong-

ured to be an audio mute switch, a power on/off switch or to be disabled. AUTO ON sets the transmitter to either turn back on and resume operation after a battery change, or to require being manually turned back on again. NOTE: The AUTO ON feature works only when the RF output carrier is turned on. TX PANEL LOCK prevents inadvertent changes to be made on the transmitter keypad. The menus can still be browsed to view the settings, but changes cannot be made. BATT TIMER is used to determine the remaining battery life based upon a test of the batteries in use. This is especially useful when rechargeable batteries are being used. Reset the time with the setup screen. Charge the batteries fully, then run them down in the transmitter with the timer running to determine the available runtime. TX BACKLIGHT adjusts the length of time that the backlight remains lit on the transmit-

ter LCD. Options are 30 seconds, 5 minutes or to remain on. RXMENU FREQ ADJUST allows manual selection of the operating frequency. AUDIO LEVEL provides a setup screen with adjustments of the analog audio output level for each channel, plus a tone output on each channel for use in adjusting the input level of a con-

nected device or sound system. MONITOR AUDIO adjusts the level of each channel that appears at the headphone jack on the front panel.

ules as needed. Any module can be installed in any position in the mainframe assembly. When the power is turned on, the modules will be detected during the bootup sequence and an icon for each one will appear on the LCD. Generate Encryption Key On the receiver LCD, navigate to the KEY MANAGE-

MENT item in the Top Menu and press the encoder to enter the setup screen. In this setup screen, the type of encryption key policy can be set, a new key generated or the existing key can be deleted. Select the NEW KEY option and press the encoder to enter the setup screen. NOTE: It is generally more convenient to use a PERSISTENT key during setup, since power may be need to be cycled on and off on the transmitters or receiver until the system is completely set up. The stored key can be deleted manually with the WIPE KEY option. Initial Transmitter Setup Attach the antenna and install the batteries into the transmitters that will be used. Turn the power on and observe the BATT LED on the transmitter. Verify that the batteries are fresh or fully charged (the LED will glow green with good batteries). Transfer Encryption Key to Transmitters On the receiver LCD, navigate to the KEY TRANSFER item in the Top Menu and press the encoder to enter the setup screen. The encryption key policy can be congured as:

A PERSISTENT key will remain in receiver and trans-

mitter memory until it is replaced with a new key or manually deleted using WIPE KEY in the menus. A ONE-TIME ONLY key is used for maximum secu-

rity. The key exists only as long as the power on both receiver and transmitter remains on during a single session. If a transmitter is powered off, but the receiver has remained turned on, the key must be sent to the transmitter again. If the power is turned off on the receiver, the entire session concludes and a new key must be generated and sent to all transmitters. In either key policy, there are 256 instances available each time a new key is generated. Instance refers to a transfer of the key from receiver to transmitter. Each instance contains a unique key. The number of instanc-

es is reduced each time a key is transferred. When the number of instances reaches 10, a warning will be displayed on the LCD. YES indicates the transmitter is connected Connect the transmitter with the key cable and press the encoder to start the transfer. The LED on the top right corner of the keypad will glow blue when the key has been transferred successfully. NOTE: The key can be transferred with the transmitter either fully powered up or in the standby mode with the RF output turned off. 20 LECTROSONICS, INC. Frequency Selection Manual selection may be necessary if frequencies are mandated by an authority, such as a major sporting event. You can manually set the frequencies and set-

tings for the transmitters in the receiver, then connect a transmitter and transfer settings. Or, of course, just manually set the frequency in each receiver channel and transmitter. Using Smart TuneTM is the easiest way to nd and set good operating frequencies. The process scans the tuning range of designated channels, identies a good operating frequency and prompts the operator to connect a transmitter and transfer the settings. The transfer can be completed or skipped, and scanning will then continue with the next receiver. Manual Frequency Selection From the Main Window, press the numbered channel select button under the LCD on the front panel to open the receiver setup screen. Rotate the encoder to select the EDIT option. Press the encoder to highlight the EDIT option and then rotate the encoder to select the left or right hand frequency item. The left hand item adjusts frequency in 1 MHz steps, and the right hand item adjusts frequen-

cy in 25 kHz steps. Selected item is indicated with ruled lines above and below Press the encoder to highlight the selected item and then rotate it to set the frequency. Then press the encoder to de-highlight it, rotate the encoder to select the other frequency item and press the encoder to highlight it. Adjust in 1 MHz steps Adjust in 25 kHz steps DSW Digital Wireless System After adjusting the frequency, press the BACK but-

ton on the front panel or the encoder to de-highlight the item. Then press the BACK button to leave the EDIT option. Use the SEL RX option or return to the Main Window to move to another receiver to adjust its frequency. Selected receiver Select the SEL RX option and press the encoder Press the encoder to de-highlight SEL RX. Select the EDIT option and repeat the above procedure. Using Smart TuneTM for Frequency Selection When new frequencies must be discovered, this auto-

matic frequency scanning and setup function is by far the easiest and quickest way to get up and running. Select the SMART TUNE item in the Top Menu and press the encoder to open the setup screen. A check box next to each receiver indicates whether or not the channel will be included in the scanning and setup process. Press the channel select buttons on the keypad below the LCD to check or uncheck each channel. Normally, a single scan on each channel is adequate to identify good operating frequencies. If you prefer, up to 10 scans can be performed on each frequency. Select the number of scans with the NUM SCAN PASS option. Selects the number of scans on each channel Rio Rancho, NM 21 Attach Microphone and Adjust Transmitter Gain This adjustment is very important to optimize the sig-

nal to noise ratio and dynamic range that the system is capable of delivering. It is best to go through the following procedure with the transmitter in the standby mode so that no audio will enter the sound system or recorder during adjustment. 1) With fresh batteries in the transmitter, power the unit on in the standby mode (see previous section Pow-

ering On in Standby Mode). 2) Navigate to the Gain setup screen. Gain Freq. ProgSw Rolloff Gain 25 Gain 25

-40

-20 0

-20 0 Peak audio level indication 3) Position a microphone the way it will be used in actual operation and have the user speak or sing at the loudest level that will occur during use, or set the output level of the instrument or audio device to the maximum level that will be used. 4) Use the and arrow buttons to adjust the gain until the peak indicator on the audio level display ickers during loud audio passages. NOTE: The peak indicator does not mean the audio is distorted. It simply means full modulation has been achieved. The input limit will cleanly handle increased levels up to 30 dB above this point. 5) Once the audio gain has been set, the signal can be sent through the sound system for overall level adjustments, monitor settings, etc. 6) Always leave the transmitter gain adjustment set according to these instructions. Adjustment only needs to be made if a different person, microphone, microphone placement, or a different instrument is used. Do not change it to adjust the audio output level of the receiver. If the audio output level of the receiver is too high or low, use only the controls on the receiver to make that adjustment. DSW Digital Wireless System Select BEGIN in the setup screen and press the en-

coder to start the process. Scanning will proceed one at a time on each receiver, from the lowest numbered one to the next higher numbered one. Each scan pass takes about 20 seconds. After the scan on the rst receiver is completed, the receiver will be set to the newly identied frequency. A mes-

sage will appear on the LCD, prompting to connect a transmitter and transfer the settings from the receiver. To set up the transmitter, turn its power on, connect it with the USB cable, select SEND TX SET and press the encoder to start the transfer. Transmitter setup can also be skipped at this time and set up later. NOTE: It is best to set up transmitters when prompted, and leave them turned on for subsequent scans, so their signals will be included in nding clear spectrum for new frequencies. Navigate to the TX MENU on the receiver and select the desired channel. Connect a transmitter to the receiver with the USB cable. Select the SEND SET op-

tion at the bottom of the screen and press the encoder. After all frequencies have been selected and settings have been transferred to the transmitters, nish the transmitter setup by adjusting the input gain on each one to match the users voice with the microphone in the position it will be used. 22 LECTROSONICS, INC. DSW Digital Wireless System NOTE: If the transmitter is driven hard into limiting, up to 30 dB, the output level of the receiver will be a few dB above this nominal level. Once the input level on the connected device is set, turn the tone generator off in the menu. The generator will turn off automatically when you return to the Main Window. When the receiver output and connected device input are set up in this manner, there is no need to change these settings from one event to another. As micro-

phones and microphone placement change, and with different voices, the only adjustment needed is the input gain on the transmitter. Adjust Receiver Analog Audio Output Level The analog audio output of the receiver is set at maxi-

mum, and lower levels are achieved with an attenuator to reduce the signal level to match the level require-

ments of other equipment. This means that there is no difference in signal to noise ratio regardless of where the receiver output level control is set. Any time gain is applied to the audio signal, noise is also added. The best approach is to use as much output on the receiver as possible with the least amount of gain on the connected device. Following this principle, it is generally best to use a line input on the connected device to avoid additional gain that might be applied to a microphone input. A tone generator is provided in the receiver to al-

low accurate input level adjustment of the connected device. This steady tone is the same as the maximum level that will appear at the outputs. The outputs can be set between -35 dBu and +8 dBu, in 1 dB steps. For example, if a channel is set at +0, the maximum output that will appear at that output is +0 dBu when the transmitter is driven to full modulation (the onset of limiting). The simple and accurate way to match the receiver output with the input of the connected device is using the following procedure. 1) Turn the output of the DR receiver all the down (-35 but not OFF). 2) Turn the input of the connected device all the way down, but not OFF. 3) Turn the tone on and gradually increase the output level of the receiver while observing the input level meter on the connected device. Increase the level until the input level meter indicates full scale. Input Level Meter on Connected Device
