Operations Guide – DOC. 7049C Sonnex™ Multiroom Audio System: SWAMP(I)-24X8 1

Sonnex™ Multiroom Audio System Crestron SWAMP(I)-24X8
Features and Functions
(Continued)
Dynamic Range Control—maintains even listening levels in both quiet
and loud ambient environments
Speaker Profiles—allows upload of custom preset speaker settings
Sonnex Speaker Protect™—affords extra headroom while preventing
component damage
Individual zone power control and global standby
Setup and adjustment via front panel or Sonnex Tools software
Remote fault monitoring
Seamless Crestron system integration
Heavy duty detachable terminal blocks ease speaker wire termination
Low power consumption, cool-running operation
Four-space 19” rack-mountable
The Sonnex system topology minimizes speaker wiring distances by allowing
Sonnex Link devices 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.*Contained in a compact 4-space rack, the
Sonnex system also integrates eight zones of high-performance power amplification
and signal processing, while input switching for 24 analog and digital sources.
Integrated Audiophile Amplifier
The amplifiers in the SWAMP-24X8 use a custom hybrid design that achieves the
warmth and neutrality of a fine Class AB amplifier with all of the efficiency benefits
of modern Class D.
Each of the SWAMP-24X8’s 16 channels (configured as eight zones) delivers 140
Watts into 8 Ω, or 240 Watts into 4 Ω. For large, noisy areas, any two adjacent zones
can be bridged (Zone 1 + Zone 2, Zone 3 + Zone 4, Zone 5 + Zone 6, Zone 7 + Zone
8) to produce 400 Watts per channel at 8 Ω. The SWAMP-24X8 uses only four rack
spaces while maintaining 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 a variety of stereo audio sources, both
analog and digital. Sonnex handles the multi-zone outputs from a Crestron ADMS
Intermedia Delivery System™ or CEN-TRACK TunerRack Modular Multi-Tuner
(both sold separately), plus outputs from digital television receivers and other
devices. Sonnex even accepts a direct input from the CEN-IDOCV Interface for
iPod®(sold separately) and other Crestron Home®CAT5 Balanced sources without
requiring a separate converter.
* For connection of the Sonnex Link between the SWAMP-24X8 and each SWAMPE-8, use Crestron
DM-CBL-8G or high-quality CAT5e shielded twisted-pair cable with DM-8G-CONN connectors.
The maximum cable length is 200 feet (61 meters) per run.
2 Sonnex™ Multiroom Audio System: SWAMP(I)-24X8 Operations Guide– DOC. 7049C

Crestron SWAMP(I)-24X8 Sonnex™ Multiroom Audio System
A total of 24 discrete inputs are spread across an array of connectors, including
unbalanced RCA, balanced terminal blocks, and S/PDIF coaxial. For ease of use,
descriptive names can be entered for display on the front panel LCD and push
buttons for every source input and zone output. Via the front panel controls or from a
Crestron®touch screen 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 S/PDIF digital outputs for
sharing stereo sources with centralized audio processors and AV receivers.
Sonnex Digital Audio Transport
Among the many features that set Sonnex apart from all other multiroom systems is
the Sonnex Audio Transport. On the rear of the SWAMP-24X8 are eight Sonnex
Link ports, enabling the connection of up to eight Sonnex Link devices1. 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 feet (61
meters) over a single CAT5e shielded twisted-pair (STP) cable.2, 3
While the Sonnex Link devices 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 Sonnex Link
device 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
needed 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 Sonnex Link device is also embedded in the Sonnex Link,
dramatically simplifying installation and setup through a true one-wire interface.
There is no need to set addresses or write any special programming. Simply connect
each Sonnex Link device to the SWAMP-24X8 and instantly control the complete
system from the SWAMP-24X8’s front panel or Sonnex Tools software.1
Advanced DSP
To truly deliver an ultimate listening experience in every room, Sonnex includes
built-in digital signal processing, providing a virtual 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 touch screen, keypad,
handheld remote, or mobile device as part of a complete Crestron system.
1. If using Cresnet®as the control system interface, system expansion is limited to one Sonnex Link
device. Support for more than one expander requires Ethernet as the control system interface.
2. For connection of the Sonnex Link between the SWAMP-24X8 and each Sonnex Link device, use
Crestron DM-CBL-8G or high-quality CAT5e shielded twisted-pair cable with DM-8G-CONN
connectors. The maximum cable length is 200 feet (61 meters) per run.
3. The length of Sonnex link can be extended to 2000 ft (610 m) over one multimode fiber strand with
the use of the S-EXT1-S (sold separately).
Operations Guide – DOC. 7049C Sonnex™ Multiroom Audio System: SWAMP(I)-24X8 3

Sonnex™ Multiroom Audio System Crestron SWAMP(I)-24X8
Sonnex DSP features include:
User Controls — From a Crestron touch screen 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 more.
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 (DRC) — 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.
Sonnex Speaker Protect™ (SSP) — SSP™ output limiting assures
maximum headroom while preventing damage*to the amplifier or speakers.
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 device.
CAUTION: As speaker ratings vary greatly across manufacturers, there is
no guarantee that Sonnex Speaker Protect protects against speaker damage
in all situations.
5-Band Equalizer — 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 impact.
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 of each bussed
zone for smooth, even coverage of the complete space.
* Excessive audio volume may damage hearing. Crestron advocates enjoying music at a safe listening
level.

Crestron SWAMP(I)-24X8 Sonnex™ Multiroom Audio System
Passive Subwoofer Support
Sonnex provides extended low frequency performance in any room, providing high-
performance biamplification capability to support any 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 filters for further room correction and enhancement. With 400 Watts
available in bridged mode, there is plenty of power on hand to fill any room with
deep, gratifying bass.1
Intelligent Monitoring and Protection
To help ensure the most seamless user experience and long-lived operation, Sonnex
includes several ways to keep tabs on its operating status and health. On its own,
Sonnex possesses the intelligence to protect itself from many 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 touch screen
or mobile device, and integrators can even monitor and track the data remotely
through Crestron RoomView®software to ensure a rapid service response.
Ultimate Integration
Without question, Sonnex delivers unprecedented intelligence from source to
speaker. Via Cresnet®2 or high-speed Ethernet, Sonnex affords incredible integration
potential as part of a complete Crestron system, enabling seamless control of every
room and source through a wide selection of touch screens, keypads, wireless
remotes, computers and mobile devices. Complete setup is afforded via USB or
Ethernet using Sonnex Tools software, part of the Crestron Toolbox™ installer
toolkit.
1. Passive subwoofer support requires one zone output to drive the main left and right (i.e., satellite)
speakers, plus one additional zone output to drive a subwoofer with 140W @ 8 Ω, or two additional
zone outputs bridged to drive a subwoofer with 400W @ 8 Ω.
2. If using Cresnet as the control system interface, system expansion is limited to one Sonnex Link
device. Support for more than one expander requires Ethernet as the control system interface.
