Introduction

The latest digital radio technology is employed in the

DSQD receiver to set a new standard for performance

and ﬂexibility. Four discrete audio channels are packed

into a single half-rack chassis, with balanced analog

and Dante

digital network outputs. The receiver tunes

continuously across the UHF band from 470.100 to

614.375 MHz.

The digital architecture delivers studio quality audio with

ultra-low latency. The receiver includes an extended

operating range rivaling the best analog and Digital

Hybrid Wireless

systems with tracking ﬁlters that stay

centered on the selected frequency.

The DSQD is also backward compatible with any Digital

Hybrid Wireless® transmitters including the SM Series,

LT, HM Series, SSM, HH Series, UM400, UM400a, LM

Series, MM Series, and WM.

The receiver provides a USB port for ﬁrmware up-

dates, an IR port for fast setup and an ethernet port for

control. A large, high resolution, backlit LCD and large

membrane switches provide an intuitive interface that is

highly visible in daylight or dimly lit conditions.

Wireless Designer™ software integrates the digital and

Digital Hybrid Wireless

into a single control panel with

site scanning and frequency coordination. The software

is free and can be used while connected to equipment

or ofﬂine in planning a multi-channel system.

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.

General Technical

Description

Encryption

When transmitting audio, there are situations where

privacy is essential, such as during professional sport-

ing events, in court rooms or private meetings. For

instances where your audio transmission needs to be

kept secure, without sacriﬁcing audio quality, Lectroson-

ics implements AES256 encryption in our digital wire-

less microphone systems. High entropy encryption keys

are ﬁrst created by the DSQD Receiver. The key is then

synced with an encryption-capable digital transmitter,

via the IR port. The audio will be encrypted and can

only be decoded if both DSQD and transmitter have the

matching encryption key. If you are trying to transmit

an audio signal and keys do not match, all that will be

heard is silence.
