Sonnex™ Multiroom Audio System
"Sonnex™ redefines what multiroom audio can be. Engineered by
Crestron® — the pioneer in audio distribution control systems."
Finally—a fully-scalable audio distribution system that delivers
high-output audiophile sound quality to every room with significantly
reduced cabling, low power consumption, advanced DSP, and
integrator-friendly setup. The Sonnex™ Multiroom Audio System takes
audio distribution to a higher level, facilitating massive systems
with up to 74 zones and over 30,000 Watts of power!
Employing a whole new system topology, Sonnex minimizes speaker wiring
distances by allowing expansion units to be placed central to the
rooms they serve, routing 24 stereo channels of uncompressed digital
audio and control to each expander over a single inexpensive shielded
CAT5e cable[1]. Gone is all the clutter of amplifier interconnects
and input loop-thru cables, meticulously integrating 8 zones of
high-performance power amplification and signal processing, plus input
switching for a generous 24 analog and digital sources, all in one
compact 4-space rack-mountable package.
Integrated Audiophile Amplifier
With Sonnex, you get more power to the speakers—without
compromising the electric bill or hogging precious space in your
equipment rack. Taking its cues from our PROCISE™ PROAMP line of
professional surround sound amplifiers, the SWAMP-24X8 boasts a custom
hybrid design that achieves the warmth and neutrality of a fine Class
AB amplifier with all the efficiency benefits of modern Class D.
Designed to appease the most demanding listener, Sonnex possesses the
sonic integrity of a world-class stereo amplifier eight times over to
deliver faithful, eminently satisfying audio reproduction in every
room from all your music sources.
Each of its 16 channels (configured as 8 zones) delivers an
unprecedented 140 Watts into 8 Ohms, or 240 Watts into 4 Ohms. And,
for those large, noisy areas around the pool or patio, or perhaps in a
game room or gym, any two adjacent zones can be bridged to produce a
gratifying 400 Watts per channel at 8 Ohms. As impressive as that is,
you'll be equally pleased to know that Sonnex accomplishes its
class-leading performance in a mere four rack spaces while maintaining
highly effective cooling with no need for extra clearance above or
below. Each zone is individually controllable, saving further energy
by turning off any unused channels.
24x8 Matrix Switcher
Designed with flexibility and expansion in mind, the Sonnex Multiroom
Audio System provides numerous inputs to manage all your stereo audio
sources, both analog and digital. Sonnex easily handles the multi-zone
outputs from a Crestron ADMS Intermedia Delivery System™ or CEN-TRACK
multi-tuner, plus all your digital television receivers and other
devices. Sonnex even accepts a direct input from the CEN-IDOCV
Interface for iPod® and other Crestron Home® CAT5 Balanced sources
without requiring a separate converter.
A total of 24 discrete inputs are spread across an array of
connectors, including unbalanced RCA, balanced terminal blocks, and
SPDIF coaxial. For ease of use, descriptive names can be entered for
display on the front panel LCD and pushbuttons for every source input
and zone output. Via the front panel controls or from a Crestron
touchpanel or remote, any input can be selected for listening in any
zone or group. Additional features include mono summing for
distribution to non-stereo zones, scaling factor settings for defining
minimum and maximum volume levels, source signal detection, and
source gain compensation to assure a consistent level when switching
between disparate sources.
Bonus Zones
Sonnex leaves no zone behind, providing two additional SPDIF digital
outputs for sharing stereo sources with centralized audio processors
and AV receivers.
Sonnex Digital Audio Transport
Among the many exceptional features that set Sonnex apart from all
other multiroom systems is the remarkable Sonnex Audio Transport. On
the rear of the SWAMP-24X8 are eight Sonnex Link ports, enabling the
connection of up to eight SWAMPE-8 expanders[2]. Each link
transports professional-quality 24-bit, 48 kHz digital audio from all
24 inputs simultaneously to each expander, supporting wiring distances
up to 200 ft (61 m) over a single CAT5e shielded twisted-pair (STP)
While the expanders can be installed centrally with the SWAMP-24X8,
the ease of running just one tiny wire instead of 16 heavy speaker
cables clearly affords a much better decentralized system approach.
Installing each expander local to the rooms it serves, whether on a
different floor, another wing, or a completely separate building,
significantly reduces the amount of speaker wiring you'll need to
install. The benefits of reducing speaker wiring include faster,
easier and less expensive installation, as well as overall higher
performance and efficiency by minimizing the signal loss inherent in
long speaker runs.
Plug and Play Expansion
Control for each expander is also embedded in the Sonnex Link,
dramatically simplifying installation and setup through a true
one-wire interface. There's no need to set addresses or write any
special programming, simply connect each expander to the SWAMP-24X8
and instantly control the complete system from the SWAMP-24X8's front
panel or Sonnex Tools software.[2]
Advanced DSP
To truly deliver an ultimate listening experience in every room,
Sonnex includes built-in digital signal processing providing a virtual
SWAMP-24X8 Sonnex™ Multiroom Audio System
arsenal of controls and adjustments, intelligently deployed to
streamline both the installer setup procedure and day-to-day user
operation. Key setup functions are accessible via the front panel,
while more advanced settings are provided via Sonnex Tools software.
Naturally, the essential user controls can be made available on any
Crestron touchpanel, keypad, handheld remote, or mobile device as part
of a complete Crestron system.
passive in-wall, in-floor, or freestanding subwoofer. Configuring
Sonnex to handle a 2.1 speaker system is both simple and powerful
using its parametric equalizers, offering the choice of 2nd or 4th
order active crossover filters for each sub and satellite output, plus
up to four additional EQ filters for further room correction and
enhancement. With 400 Watts available in bridged mode, there's plenty
of power on hand to fill any room with deep, gratifying bass.[4]
Sonnex DSP features include:
Intelligent Monitoring and Protection
To help ensure the most seamless user experience and long-lived
operation, Sonnex includes several ways to keep tabs of its operating
status and health. On its own, Sonnex possesses the intelligence to
protect itself from all types of faults including over temperature,
over current, over voltage, under voltage, and DC offset on any
channel. In the event of a fault, the front panel LCD provides clear
fault indication to speed the troubleshooting of incorrect wiring,
poor rack ventilation, and other unforeseen issues. Fault alerts may
also be broadcast to a system touchpanel or mobile device, and
integrators can even monitor and track the data remotely through
Crestron RoomView® software to ensure a rapid service response.
• User Controls - From a Crestron touchpanel or other user interface,
Sonnex provides the essential controls for day-to-day listening.
Controls include room volume, bass, treble, balance, loudness, mute,
zone on/off, and five selectable tone profiles. Through the control
system program, many advanced user functions are possible including
priority modes (who can control which sources), zone grouping (source
sharing), paging, do-not-disturb, alarm clock, sleep timer, and much
• Tone Profiles - With one touch, users can select from five preset
EQ curves including Classical, Jazz, Pop, Rock, or Spoken Word, each
tailored for a different type of material or listening preference.
• Dynamic Range Control - When you listen to music or watch TV, you
want to enjoy it at a volume level that lets you hear everything
clearly - which can be difficult to do if there are competing
background noises or someone resting in the next room. Not only that,
but the level from one song to the next, and between TV programs and
commercials, can fluctuate wildly. Sonnex provides user-selectable DRC
to help keep everything at a consistent level, whether in a quiet
bedroom, a loud swimming pool, or an outdoor patio, facilitating a
more cohesive listening experience without disturbing the neighbors.
• Sonnex Speaker Protect™ - When the occasion calls for cranking the
volume[3], exclusive SSP output limiting assures maximum headroom
while preventing damage to the amplifier or speakers. More
sophisticated than conventional limiting, SSP lets the installer set
the protection to match the speakers' power handling capability,
achieving a transparent effect right up to the limits of the speaker
• 5-Band Equalizer - To tailor the sound of your speakers to the
unique acoustical environment of each room or space, Sonnex provides
the choice of graphic or parametric 5-band EQ. Using Sonnex Tools
software and a wireless laptop, the installer can easily move from
room to room, sculpting the sound for optimal audio clarity and
Speaker Profiles
AV system integrators typically rely on just a few select speaker
models for the majority of installs, and subsequently find themselves
repeating many of the same adjustments at each project. The Speaker
Profiles feature in Sonnex Tools alleviates the repetition, allowing
installers to save a complete set of EQ and SSP settings for every
type of speaker, room, and customer listening preference. So, tuning
the next room or project can be as simple as loading the appropriate
Speaker Profile for each zone. Using Speaker Profiles, a complete
Sonnex system can be effectively "pre-tuned" before a single note of
music or test signal is even played.
Output Bussing
The spacious, open floor plans typical of today's homes and offices
commonly present multiple adjacent listening zones with no sonic
boundary between them - e.g., a kitchen and dinette, a living room and
dining room, or an outdoor pool and terrace. One click in Sonnex
Tools instantly busses adjacent zones together to function as one
group while preserving the individual speaker profile settings for
each. Volume Offset adjustments easily allow for balancing the levels
