Introduction
The latest digital radio technology is employed in the
DSQD receiver to set a new standard for performance
and exibility. Four discrete audio channels are packed
into a single half-rack chassis, with balanced analog and
Dante®digital network outputs. The receiver tunes con-
tinuously 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 op-
erating range rivaling the best analog and Digital Hybrid
Wireless®systems with tracking lters 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 rmware updates,
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 vis-
ible 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
oine 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 sporting
events, in court rooms or private meetings. For instances
where your audio transmission needs to be kept secure,
without sacricing audio quality, Lectrosonics imple-
ments AES256 encryption in our digital wireless micro-
phone systems. High entropy encryption keys are rst
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 match-
ing 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 suer from channel noise to some degree,
and all wireless microphone systems seek to minimize the
impact of that noise on the desired signal. Conventional
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 conjunction
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 multichan-
nel systems where a pilot tone signal can appear 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 comprehensive
monitoring of all receiver parameters.
Diversity Reception
Three dierent receiver diversity schemes can be em-
ployed depending on the needs of the application,
including antenna switching (during packet headers for
seamless audio), Digital Vector Diversity or Digital Fre-
quency Diversity.
NOTE: Ratio Diversity instead of Vector Diversity
is available in earlier models, which is explained
on page 10.
Infrared Sync
The DSQD has a bi-directional IrDA interface which al-
lows quick syncing of settings and encryption keys to
transmitters (including legacy transmitters) with the push
of a button. The receiver also oers 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
exible Internet Protocol (IP) and Ethernet based digital
AV network technology that eliminates the many bulky
cables needed to provide point-to-point wiring for analog
AV installations.
With Dante, existing infrastructure can be used for high
performance audio as well as for ordinary control, moni-
toring or business data trac. Digital networks utilize
standard IP over Ethernet oering high bandwidth ca-
pable of transporting hundreds of high quality channels
over Gigabit Ethernet.
Set-up and conguring 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 congured in software, not via
physical wired links.
Summary of Dante Benets
• 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

RF Level Status
RF level status (and things you may need to check) is
indicated by the color that appears in the status bar.
• Green: The receiver is successfully demodulating the
signal and correctly supplying audio.
• Yellow: The receiver is able to see the signal but the
audio is currently squelched, either becuase of poor
signal quality or encryption issues. Pilot tone and/or
digital packet headers are present.
• Red: The receiver sees RF energy but cannot
comprehend it in the current Compatibility mode. this
means no Pilot tone in Hybrid modes and no Packet
Headers in digital modes. Can be caused by external
interference.

Diversity Setup
Diversity is a DSQD feature that safeguards against loss of audio signal caused by RF interference. The DSQD archi-
tecture allows three dierent types of diversity reception. Once chosen, the diversity mode is shown on other screens
with a link icon. (Visit the DSQD page on lectrosonics.com for a video with more details on Diversity.)
Vector Diversity
Icon
Frequency Diversity
Icon
• Switched: Of the two antennas available on the DSQD, the receiver selects the antenna with the best signal. In
this mode, there are four receivers available.
• Vector: In this mode, two receiver channels can be “paired” as one receiver. Either Channels 1 and 2 or channels 3
and 4 can be combined into a pair. One receiver in a pair is xed on Antenna A and the other receiver in a pair is xed
on Antenna B. The DSQD automatically and optimally combines the intermediate frequency signals.
NOTE: Vector diversity is available in units with serial numbers higher than 6500661 in DSQD and 6500601 in
DSQD/AES3. In units with earlier serial numbers, ratio diversity is available.

Digital Receiver
Rio Rancho, NM 11
• Frequency: Again, the receiver channels are paired. In this mode, each channel is set to a dierent frequency.
The DSQD automatically uses whichever receiver’s RF signal quality is better. The use of separate frequencies
helps minimize dropouts caused by multi-path phenomenon. This technique uses both switched and vector
diversity for maximum eectiveness.
NOTE: To maximize frequency diversity, choose frequencies separated as far apart as possible.
When using Frequency Diversity, performance can be optimized by using a calibration technique to balance the audio
levels between the two transmitters in the pair. Follow these steps:
1. Plug headphones into the DSQD front panel monitor jack.
2. Select CALIBRATE on the Diversity Setup screen.
3. The Calibrate TX Gain pop-up screen will appear.
4. Adjust the microphone gain on each transmitter to balance the audio level while observing the green bar on the
screen. When audio level is balanced, the green bar is minimized.
WARNING: Use caution when calibrating. Resulting headphone volume may be very loud.
WARNING: Transmitter gain should also be set in accordance with transmitter manual to achieve correct
modulation.

Audio Setup Menu
Audio Level
Set audio output level with the level control. The mute
button is a toggle used to mute or unmute the audio out-
put. The TONE check box is used to generate a
1 kHz test tone at the audio output.
Audio Polarity
Select normal or inverted polarity for each
audio channel.
Smart Noise Reduction
Three levels of noise reduction are available: High, Nor-
mal and O.
NOTE: Smart Noise Reduction is only available
for digital hybrid compatibility modes.
Compatibility Modes
Multiple compatibility modes are available to match vari-
ous transmitter types.
The following modes are available:
• D2: Encrypted digital wireless channel
• DCHX: Two channel encrypted mode.
• DUET CH1: To receive Channel One audio from a
Duet transmitter
• DUET CH2: To receive Channel Two audio from a
Duet transmitter
• HDM: High density mode
• NA HYB: Legacy digital hybrid mode
• EU HYB: Used only for certain digital hybrid trans-
mitters marketed in the European Union
• NU HYB: Digital hybrid mode for current Lectro-
sonics transmitters
• JA HYB: Used only for certain digital hybrid trans-
mitters marketed in Japan
Talkback Setup
Talkback is a special function that re-directs the audio
output of the transmitter in use to a dierent receiver
output when talkback is selected on the transmitter. The
normal use is to provide a “comm” channel so the person
using the transmitter can have a direct line to the crew or
production sta. When selected, the audio will appear at
the designated talkback channel rather than the channel
used for program audio.
IR Sync & Encryption Menu
Encryption Key Management
The DSQD has three options for encryption keys:
• Standard: This is the highest level of security.
The encryption keys are unique to the DSQD and
there are only 256 key instances available to be
transferred to a transmitter. The receiver tracks the
number of keys generated and the number of times
each key is transferred. Once a Standard key has
been transferred 256 times, you will be alerted that
a new key must be created.
• Shared: There are an unlimited number of
shared keys available. Once generated by the
DSQD and transferred to a transmitter, the encryp-
tion key is available to be shared (synced) by the
transmitter with other transmitters/receivers via the
IR port.
• Universal: This is the most convenient en-
cryption option available. All encryption-capable
Lectrosonics transmitters and receivers contain
the Universal Key. The key does not have to be
generated by the DSQD. Simply set a Lectroson-
ics encryption-capable transmitter and the DSQD
to Universal, and the encryption is in place. This
allows for convenient encryption amongst multiple
transmitters and receivers, but not as secure as
creating a unique key.
Encryption Keys
The DSQD generates high entropy encryption keys to
sync with encryption-capable transmitters. The user
must select a key type and create a key in the DSQD,
and then sync the key with a transmitter.
1. Begin by selecting a key type.

Digital Receiver
Rio Rancho, NM 13
2. The DSQD will then display a warning to indicate
that there is NO KEY! Select CREATE KEY to gen-
erate a new key.
NOTE: When Universal Key type is selected,
there is no prompt to create key. See Encryption
Key Management for more information.
3. A message will pop up on the screen warning the
user that all transmitters will need a new key. Se-
lect OK. The creation of a new key is conrmed.
4. Sync new key with transmitter (see Sync Key). The
transmitted audio will then be encrypted with the
new key.
Sync Settings
Allows sending or retrieving setup data, including fre-
quency, name and talkback settings, via the IR port.
There are two ways to initiate a sync.
Sync options: Choose to send frequency, send all
settings, retrieve (get) frequency or retrieve (get) all
settings from a transmitter. Use the UP and DOWN

updates are available by simply clicking on an item in the
Help Menu.
NOTE: If Wireless Designer is already installed,
you must uninstall it before attempting to install
a new copy.
Firmware Update Instructions
Firmware updates are made with a le downloaded from
the web site and the DSQD connected via USB.
The USB port on the transmitter requires a micro-B male
plug on the connecting cable. The other end of the cable
would normally be a USB A-Type male connectorto t the
most common type of USB jack used on computers.

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 at blade screwdriver
to pry the tabs outward and snap them o of the
chassis.
3. Insert the ange 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.
