Lectrosonics DSQD Receiver
MPN #DSQD
Half Rack Receiver with analog and digitalDante network audio outputs utilizes the Lectrosonics signature digital architecture with remarkable audioquality 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.
The DSQD Receiver is a four-channel design with a host mainframe that contains the DSP, microprocessor,
antenna multicoupler and control interface.
Antenna ports on the rear panel accept input from remote antennas, with a "loop-thru" output to another
mainframe using the internal multicoupler. A kit is also available to mount antenna inputs (BNC connectors)
on the front panel.
DSQD Front Panel
Headphone Monitor
Monitor any individual audio channel, or a stereo mix between pairs. Volume knob recesses into front panel.
LCD Control Panel
Easy navigation of all setup parameters is provided by a full color, backlit, LCD screen and membrane push
buttons. The high resolution display provides fantastic monitoring of all receiver parameters.
2-Way IR
A bidirectional IrDA interface allows quick syncing of settings and encryption keys to transmitters with the
push of a button.
USB Port
Easily interface to Wireless Designer or third-party software via the standard USB port, greatly accelerating
setup time and expanding system monitoring capabilities.
LED Indicators
Two LEDs provide positive indication of antenna bias power state.
DSQD Rear Panel
Antenna Ports
Antenna inputs and outputs to an additional DSQD allow "stacking" of up to three mainframes with a single
pair of antennas.
Audio Outputs
Four full-size XLR jacks provide analog outputs.
Dante Ethernet Ports
Dual Dante Ethernet ports provide the ability to daisy chain multiple DSQDs onto a Dante Audio Network.
Ethernet Port
Easily interface to Wireless Designer or third-party software via the control Ethernet port, greatly accelerating
setup time and expanding system monitoring capabilities.
Power Supply Input
The DSQD is powered by 7 to 18 VDC from an external source capable of 2.5 amps.
