DSW System DR Receiver/DB Transmitter INSTRUCTION MANUAL Rio Rancho, NM, USA www.lectrosonics.com Fill in for your records: Serial Number: Purchase Date: Essential Setup Steps 1) Install receiver modules, antennas and connect to a power supply (see page 6) 2) Generate an encryption key (see page 20) 3) Install transmitter batteries and antennas (see page 15) 4) Transfer encryption key to transmitters (see page 20) 5) Identify and set operating frequencies on the receiver using Smart Tune TM (see page 21) (the procedure includes transferring frequency settings to the transmitters) 6) Attach microphones and adjust transmitter input gain (see page 22) 7) Verify operation with a walk test through the area where the system will be used DSW Digital Wireless System LECTROSONICS, INC. 2 DSW Digital Wireless System Rio Rancho, NM 3 Introduction DSW (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 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.
