Overview
Lectrosonics DSQD, 4-Channel Digital Receiver with Dante & Analog
The Lectrosonics DSQD is a half rack receiver with analog and digital Dante® network audio outputs that utilize Lectrosonics signature digital architecture with remarkable audio quality and ultra-low latency. The receiver includes an extended operating range rivaling the best analog and Digital Hybrid Wireless ® systems with continuously tunable tracking filters covering 470.100 - 614.375 MHz. Antenna ports on the rear panel accept input from remote antennas, with a "loop-thru" output to another mainframe using the internal multi coupler.
