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.
DSP algorithms provide compatibility with Lectrosonics
DSW and Duet digital wireless transmitters, and with
Lectrosonics Digital Hybrid Wireless® transmitters.
The receiver provides a USB port for firmware updates
and an IR port for fast setup. 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 introduces Encryption Keys. Truly entropic encryption keys are first created by the DSQD Receiver. The
key is then synced with an encryption-capable transmitter, via the IR port. The audio will be encrypted and can
only be listened to 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 or white noise.

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 algorithums
for compatibility with Digital Hybrid Transmitters.
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.
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
