Lectrosonics DSQD Datasheet

DSQD

4 Channel Digital Receiver

TECHNICAL DATA

• Four-channel, half-rack design

• Continuously tunable tracking filters
covering 470.100 - 614.375 MHz

• Compatible with DSW, Duet and
Digital Hybrid Wireless® transmitters

• Built-in wideband antenna multicoupler with
loop-thru for additional receivers

• Antenna bias power enabled from the
front panel (fused and over-temperature
protected)

• IR bi-directional port for transmitter setup

• Analog and Dante® audio outputs with
TalkBack (in applicable RX modes)

• Ethernet and USB interface

• Offline full-system frequency coordination

The DSQD Half Rack Receiver with analog and digital
Dante® network audio outputs utilizes the 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.

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.
