Description

Lectrosonics DSQD 4 Channel Digital Receiver

  • 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 Lectosonics 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 Lectosonics  DSQD is powered by 7 to 18 VDC from an external source capable of 2.5 amps.
