DSW Digital Wireless SystemRio Rancho, NM 3IntroductionDSW (Digital Secure Wireless) is designed for no-com-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 ReceiverThe 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 TransmitterThe 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.Table of ContentsEssential Setup Steps ..........................................................1Introduction ............................................................................3Receiver Front Panel .............................................................4Headphone output ...............................................................4LCD and control Interface ....................................................4Encryption key and settings transfer port .............................4USB Port ..............................................................................4Comm LED ..........................................................................4Alert LED .............................................................................4Power LED ...........................................................................4Receiver Rear Panel ..............................................................5Antenna connections ...........................................................5Audio Outputs ......................................................................5Ethernet Port ........................................................................5AES Word Clock ..................................................................5RS-232 Port .........................................................................5Antenna Cable Front Panel Pass-thru ..................................5Power Supply .......................................................................5Hardware Installation ............................................................6Receiver Modules ................................................................6Antenna Connections ...........................................................6Audio Output Wiring - Analog ...............................................6Audio Output Wiring - AES3 Digital ......................................7Connections for Computer Interface ....................................7RS-232 Port Pinouts ............................................................7Ethernet Port ........................................................................7Receiver LCD Interface .........................................................8Navigating the Menus ..........................................................9Menu Map and Icons .........................................................10Software Installation ...........................................................13Windows Installation ..........................................................13Mac Installation ..................................................................14Connecting to a Network ....................................................14Using DHCP for IP Address Assignment ...........................14DB Transmitter .....................................................................15Features and Functions .....................................................15DB Transmitter LCD Interface ............................................15Powering On in Operating Mode ........................................16Powering On in Standby Mode ..........................................16Powering Off ......................................................................16Power Menu .......................................................................16Navigating Menus ..............................................................17Adjusting LCD Backlight ....................................................17Locking/Unlocking Changes to Settings.............................17Selecting Programmable Switch Functions........................17Other Menu Items ..............................................................17DB Transmitter Menu Map .................................................18Copying Transmitter Settings To and From the Receiver ...19System Setup .......................................................................20Specifications ......................................................................24Service and Repair ..............................................................25Returning Units for Repair .................................................25FCC Notice ...........................................................................26

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.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 SetupAttach 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 TransmittersOn the receiver LCD, navigate to the KEY TRANSFER item in the Top Menu and press the encoder to enter the setup screen. YES indicates the transmitter is connectedConnect 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.
DSW Digital Wireless SystemRio Rancho, NM 21Frequency SelectionManual 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 find and set good operating frequencies. The process scans the tuning range of designated channels, identifies 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 SelectionFrom 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 belowPress 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 stepsAfter 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 receiverSelect the SEL RX option and press the encoderPress the encoder to de-highlight SEL RX. Select the EDIT option and repeat the above procedure.Using Smart TuneTM for Frequency SelectionWhen 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
DSW Digital Wireless SystemLECTROSONICS, INC.22Select 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 first receiver is completed, the receiver will be set to the newly identified 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 finding 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, finish the transmitter setup by adjusting the input gain on each one to match the user’s voice with the microphone in the position it will be used.Attach Microphone and Adjust Transmitter GainThis 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.GainFreq.ProgSwRolloff -40 -20 0Gain25-40 -20 0Gain25Peak audio level indication3) 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 flickers 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 SystemRio Rancho, NM 23Adjust Receiver Analog Audio Output LevelThe 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. OVROVR-200-10-200-10Input Level Meter on Connected DeviceNominal levelIf the receiver output is turned all the way up and the nominal level on the input meter is not achieved, turn the gain on the connected device input up gradually until a full scale reading is indicated.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.
