Whenever I need to buy new kit this is the place to go. Wendy and her team have excellent knowledge of the equipment they supply, access to information from manufacturers about the kit and an attitude to genuine customer service that is not often found in today's globalised corporate world. I have dealt with all the main UK broadcast suppliers and buying from Wendy's is by far the best experience.
DSQD 4-way backward compatible digital half-rack receiver
DSQD
The DSQD Half-Rack Receiver is a four channel receiver backwards compatible with SM, LT, HM, SSM, HH UM400(a), LM, MM, and WM transmitters. It's part of the D Squared digital wireless system.
Four discrete audio channels are packed into a single half-rack chassis, with balanced analog and Dante® digital network outputs. The receiver tunes continuously across the UHF band from 470.100 to 614.375 MHz.
The digital architecture delivers studio quality audio with ultra-low latency. The receiver includes an extended operating range rivaling the best analog and Digital Hybrid Wireless® systems with tracking filters that stay centered on the selected frequency.
The DSQD is also backward compatible with any Digital Hybrid Wireless® transmitters including the SM Series, LT, HM Series, SSM, HH Series, UM400, UM400a, LM Series, MM Series, and WM.
The receiver provides a USB port for firmware updates, an IR port for fast setup and an ethernet port for control. A large, high resolution, backlit LCD and large membrane switches provide an intuitive interface that is highly visible in daylight or dimly lit conditions.
Wireless Designer software integrates the digital and Digital Hybrid Wireless into a single control panel with site scanning and frequency coordination. The software is free and can be used while connected to equipment or offline in planning a multi-channel system.
Antenna ports on the rear panel accept input from remote antennas, with a “loop-thru” output to another mainframe using the internal multicoupler.
Each DSQD ships with half the rack hardware needed to mount two units together, yielding 8 channels in 1RU.
