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 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 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 sporting events, in court rooms or private meetings. For
instances where your audio transmission needs to be
kept secure, without sacrificing audio quality, Lectrosonics implements AES256 encryption in our digital wireless 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.

LECTROSONICS, INC.
Digital Receiver
Digital Hybrid Wireless® Technology
All wireless links suffer 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
multichannel 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 buttons. The high resolution display provides comprehensive 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 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 analog AV installations.
With Dante, existing infrastructure can be used for high
performance audio as well as for ordinary control, monitoring or business data traffic. Digital networks utilize
standard IP over Ethernet offering high bandwidth capable 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

DSQD Manual
Diversity Setup
Diversity is a DSQD feature that safeguards against loss of audio signal caused by RF interference or by power loss
in a transmitter. The DSQD architecture allows three different 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.)
Ratio 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.
• Ratio: 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 fixed on Antenna A and the other receiver in a pair is
fixed on Antenna B. The DSQD automatically uses whichever receiver’s RF signal quality is better.
10
LECTROSONICS, INC.
Digital Receiver
• Frequency: Again, the receiver channels are paired. In this mode, each channel is set to a different 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 ratio diversity for
maximum effectiveness.
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.

NOTE: Smart Noise Reduction is only available for
digital hybrid compatibility modes.
Compatibility Modes
Multiple compatibility modes are available to match various transmitter types.
The following modes are available:
• D2: Encrypted digital wireless channel
• DUET CH1: To receive Channel One audio from a
Duet transmitter
• DUET CH2: To receive Channel Two audio from a
Duet transmitter
• NA HYB: Legacy digital hybrid mode

LECTROSONICS, INC.
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 encryption key is available to be shared (synced) by the
transmitter with other transmitters/receivers via the
IR port.
• Universal: This is the most convenient encryption 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 Lectrosonics 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.
Digital Receiver
3. A message will pop up on the screen warning the
user that all transmitters will need a new key. Select
OK. The creation of a new key is confirmed.
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 via the IR port.
Sync options: Choose to send frequency, send all
settings, retrieve (get) frequency from a transmitter
or retrieve (get) all settings from a transmitter.
Choose Transmitter: Choose one of four Rx chan-
nels by using the Channel Selector Buttons, 1, 2,
3 or 4.
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.
2. The DSQD will then display a warning to indicate
that there is NO KEY! Select CREATE KEY to
generate a new key.
NOTE: You must position the transmitter’s IR port
directly in front of the DSQD IR port, as closely as
possible, to guarantee a successful sync.
Sync Key
Send or retrieve (get) encryption keys.
NOTE: When Universal Key type is selected, there
is no prompt to create key. See Encryption Key

DSQD Manual
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.
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.
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.

panels, and then use them to attach the rear tie
bracket. Do not tighten the screws completely.

(Part #25991)
Slide the other receiver over the tie bracket and in-
sert the screws, but do not tighten them completely
until the rear tie bracket is installed.

the receivers on a flat surface so the that the front
panels are even with each other. Hold the receivers
in place and tighten all cap screws on the front and
rear brackets.

DSQD Manual
Service and Repair
If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment
needs repair. Make sure you have followed the setup procedure and operating instructions. Check the interconnecting
cables and then go through the Troubleshooting section in this manual.
We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connection,
send the unit to the factory for repair and service. Don’t attempt to adjust any controls inside the units. Once set at the
factory, the various controls and trimmers do not drift with age or vibration and never require readjustment. There are
no adjustments inside that will make a malfunctioning unit start working.
LECTROSONICS’ Service Department is equipped and staffed to quickly repair your equipment. In warranty repairs
are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest
flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it does
to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by phone
for out-of-warranty repairs.
Returning Units for Repair
For timely service, please follow the steps below:
A. DO NOT return equipment to the factory for repair without first contacting us by email or by phone. We need
to know the nature of the problem, the model number and the serial number of the equipment. We also need a
phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help speed
your repair through our receiving and repair departments. The return authorization number must be clearly shown
on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the
proper packing materials. UPS is usually the best way to ship the units. Heavy units should be “double-boxed” for
safe transport.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or dam-
age to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
