Lectrosonics DSQD/AES3 Receiver

The DSQD Half Rack Receiver with analog and digital Dante network audio outputs utilizes the Lectroson- ics 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 acceler- ating setup time and expanding system monitoring capabilities.

LED Indicators Two LEDs provide positive indication of antenna bias power state.
