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.

Digital Hybrid Wireless® Technology
All wireless links suffer from channel noise to some de-
gree, and all wireless microphone systems seek to mini-
mize the impact of that noise on the desired signal. Con-
ventional analog systems use compandors for enhanced
dynamic range, at the cost of subtle artifacts (known as
“pumping” and “breathing”). Wholly digital systems defeat
the noise by sending the audio information in digital form.
To support the installed base of Digital Hybrid Wireless
systems, the DSQD receiver includes DSP algorithms
for compatibility with Digital Hybrid Transmitters.
The DSQD receiver uses a DSP generated ultrasonic
pilot tone to reliably mute the audio when no RF carrier
is present. The pilot tone must be present in conjunc-
tion with a usable RF signal before the audio output
will be enabled. 256 pilot tone frequencies are used
across each 25.6 MHz block within the tuning range of
the system. This alleviates erroneous squelch activity in
multichannel systems where a pilot tone signal can ap-
pear in the wrong receiver via IM (intermodulation).
LCD Screen
Easy navigation of all setup parameters is provided by a
full color, backlit LCD screen and membrane push but-
tons. The high resolution display provides comprehen-
sive monitoring of all receiver parameters.
Diversity Reception
Three different receiver diversity schemes can be
employed depending on the needs of the application,
including antenna switching (during packet headers
for seamless audio), Digital Ratio Diversity, or Digital
Frequency Diversity.
Infrared Sync
The DSQD has a bi-directional IrDA interface which
allows quick syncing of settings and encryption keys
to transmitters (including legacy transmitters) with the
push of a button. The receiver also offers tuning groups
to allow the user to set up a list of frequencies, allowing
for easy tracking of frequency tuning in the transmitters.
What is Dante?
Audinate’s patent pending Dante™ technology is a
flexible Internet Protocol (IP) and Ethernet based digital
AV network technology that eliminates the many bulky
cables needed to provide point-to-point wiring for ana-
log AV installations.
With Dante, existing infrastructure can be used for high
performance audio as well as for ordinary control, moni-
toring or business data traffic. Digital networks utilize
standard IP over Ethernet offering high bandwidth ca-
pable of transporting hundreds of high quality channels
over Gigabit Ethernet.
Set-up and configuring the system is made easy as
well, saving enormous installation costs and long term
cost of ownership on a digital network. The physical
connecting point is irrelevant: audio signals can be
made available anywhere and everywhere. Patching
and routing now become logical functions configured in
software, not via physical wired links.
Summary of Dante Benefits
• Plug-and-play technology – automatic discovery
and simple signal routing
• Reduced Cost & Complexity- No special skills
required to set up audio networking
• Sample accurate playback synchronization
• Add/remove/rearrange components at will
• Deterministic latency throughout the network
• Support mixed bit depths and mixed sample
rates over one network
• Scalable, flexible network topology, supporting a
large number of senders and receivers
• Supports 1Gbps networks
• Supports a single integrated network for audio,
video, control, monitoring
• Uses inexpensive, off-the-shelf computer
networking equipment

cy coordination (coming soon).
Power Inlet
The locking DC coaxial inlet requires 7-18 VDC and
draws a maximum of 2.5 A at 7 V (with all channels
powered, Dante module powered, and antenna bias
power on both channels).
Operating Instructions
To begin using the DSQD quickly, follow the steps be-
low. The other settings can be adjusted as needed.
1. Set Channel Frequency: Assign a frequency to
each channel, which will correlate to the accom-
panying (1-4). From Channel Selector Button
the Quick Access Menu RF Setup Menuor the ,
manually set frequency on the RF Frequency
screen or scan for available frequencies and assign
a frequency to each channel from the Frequency
Scan screen.
2. Set Compatibility Mode: From the Quick Access
Menu Audio Setup Menuor the , set compatibility
modes for each channel.
3. Set Encryption Keys: From the IR Sync & En-
cryption Menu, select a key type and then create a
key (if needed).
NOTE: See for Encryption Key Management
more instruction.
4. Sync Settings: From the Quick Access Menu or
the , initiate sync for IR Sync & Encryption Menu
each channel via the IR port. Hold the target trans-
mitter close to the IR port on the front panel of the
DSQD. Select . A message will appear SEND ALL
on the main screen letting you know the sync was
successful. Messages will appear letting you know
if the sync was successful.
NOTE: See for more instruction.Sync Settings
5. You can also quickly check a channel’s status by
pressing a from the Channel Selector Button
DSQD home screen. This screen allows you to
change a variety of settings, including status of the
compatibility mode, diversity setting, transmitter bat-
tery status, audio level and audio mute status.

4. Insert two (2) cap screws (Part #28885) through the
rack handle (Part #27082) holes and install the rack
handle onto the flange bracket through the holes in
the unit’s front panel. Firmly tighten the cap screws
using the hex key (Allen wrench) as shown.
5. If antennas will NOT be mounted on the front panel
of the receivers, install the hole cap (Part #35959)
by aligning the flat on the cap with the flat on the
opening.
Installing two DSQD
Receivers into a Single
Rack Space
The DSQD receiver occupies a half rack space, and
comes with hardware to mount two receivers into a
single rack space.
1. Remove the Trim Cap (Part #P1330) from both
sides of the front panel on both receivers.
2. Remove the breakaway tabs on both sides of the
chassis side panels. Use a flat blade screwdriver
to pry the tabs outward and snap them off of the
chassis.
3. Insert the flange bracket (Part #27076) into the
open slot in the side of the chassis cover panel.
NOTE: The retaining nuts on the panel and tie
brackets are “tensioning lock nut” types designed
to prevent the screws from coming loose due to
vibration. You will usually feel resistance as you
tighten the screws - this is normal.
