Lectrosonics DSQD 4-Channel Digital Receiver, Half-Rack

Utilizing Lectrosonics' signature digital architecture for remarkable audio quality and ultra-low latency, the DSQD Half-Rack Receiver provides both analog and digital Dante® network audio outputs. It also provides an extended operating range that rivals the best analog and Digital Hybrid Wireless® systems available on the market, with continuously-tunable tracking filters covering 470.100 - 614.375 MHz. Additionally it includes a 4-channel design with a host mainframe that contains the microprocessor, DSP, control interface and antenna multicoupler. Antenna ports located on the rear panel accept input from remote antennas, with a "loop-thru" output to connect to another mainframe using the unit's internal multicoupler. A kit is available that enables the mounting of antenna inputs (BNC connectors) on the front panel.
