Description

The latest digital radio technology is employed in the DSQD receiver to set a new standard for performance and flexibility. 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.
