SWAMP(I)-24X8
Introduction
The SWAMP-24X8 is the centerpiece of 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 unique system topology, Sonnex minimizes speaker wiring distances by
allowing expansion units to be placed central to the rooms they serve. Twenty-four
stereo channels of uncompressed digital audio and control are routed to each
expander over a single inexpensive shielded CAT5e cable.* Gone is all the clutter of
amplifier interconnects and input loop-thru cables, integrating eight 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.
The SWAMP-24X8 and SWAMPI-24X8 are functionally identical. For simplicity
within this guide, the term “SWAMP-24X8” is used except where noted.
Features and Functions
(Continued on following page)
* For connection of the Sonnex Link between the SWAMP-24X8 and each expander, use Crestron®
DM-CBL-8G or high-quality CAT5e shielded twisted-pair cable. The maximum cable length using
DM-CBL-8G or CAT5e is 200 ft (61 m) per run. For longer distances, use the S-EXT1-S Sonnex

Crestron SWAMP(I)-24X8 Sonnex Multiroom Audio System
Operations Guide – DOC. 7049E Sonnex Multiroom Audio System: SWAMP(I)-24X8 •3
Integrated Audiophile Amplifier
The amplifiers in the SWAMP-24X8 use a custom hybrid amplifier 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 stereo zones) delivers
140 watts into 8 ohms, or 240 watts into 4 ohms. For large, noisy areas around the
pool or patio, or in a game room or gym, any two adjacent outputs 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 ohms. 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 multitude of stereo audio sources,
both analog and digital.
•A total of 24 discrete inputs are spread across an array of connectors,
including unbalanced RCA, balanced terminal blocks, and S/PDIF coaxial.
Sonnex easily handles the multizone outputs from a Crestron ADMS
Intermedia Delivery System™ or TunerRack Modular Multi-Tuner
(CEN-TRACK), plus digital television receivers and other devices.
•Audio return channels are easily added using Crestron AUD-EXT Audio
Extenders to receive signals from remote AV receivers located up to 2000
feet (610 m) away.
•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. 1
For ease of use, descriptive names for every source input and zone output can be
displayed on the front panel LCD and pushbuttons. 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
In addition to its eight amplified zone outputs, the SWAMP-24X8 provides two
additional S/PDIF digital outputs for sharing stereo sources with centralized audio
processors and AV receivers.2These outputs can even be extended to feed remote
AV receivers anywhere in the house using AUD-EXT Audio Extenders.
1. CH (Crestron Home) CAT5 balanced audio is supported using balanced inputs 13 – 16. All other
inputs require an ABAR-1 CAT5 Balanced Audio Receiver.
2. Additional S/PDIF and analog line outputs may be added using the SWE-8 Sonnex Multiroom Audio
Unamplified Expander (sold separately).

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 Multiroom Audio
Expanders (SWAMPE-4 or SWAMPE-8).1Each 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
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 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 expander is also embedded in the Sonnex Link, dramatically
simplifying installation and setup through a true 1-wire interface. There is 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.
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.
The following features are included in Sonnex DSP:
•User Controls allow a Crestron touch screen or other user interface to
provide 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 allow users to 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.
1. If using Cresnet as the control system interface, system expansion is limited to one expander. 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 expander, use Crestron
DM-CBL-8G or high-quality CAT5e shielded twisted-pair cable. The maximum cable length using
DM-CBL-8G or CAT5e is 200 ft (61 m) per run. For longer distances, use the S-EXT1-S Sonnex
Link over Fiber Extender.

Operations Guide – DOC. 7049E Sonnex Multiroom Audio System: SWAMP(I)-24X8 •5
•Dynamic Range Control (DRC) is a user-selectable feature 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) output limiting assures maximum headroom
while preventing damage to the amplifier or speakers. SSP®output limiting
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 SSP protects against speaker damage in all situations.
•5-Band Equalizer 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
The Speaker Profiles feature in Sonnex Tools alleviates many repetitive adjustments
from room-to-room, and project-to-project, by allowing installers to save a complete
set of EQ and SSP settings for each type of speaker, room, and customer. Tuning a
complete project can be as simple as loading the appropriate Speaker Profile for each
zone, effectively pre-tuning the whole system 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 businesses commonly
present multiple adjacent listening zones with no sonic boundary between them such
as 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.
Volume offset adjustments easily allow for balancing the levels of each bussed zone
for smooth, even coverage of the complete space.
Passive Subwoofer Support
Sonnex provides extended low frequency performance in any room, providing high-
performance biamplification capability to support a passive in-wall, in-floor, or
freestanding subwoofer. Configuring Sonnex to handle a 2.1 speaker system is both
simple and powerful, offering the choice of 2nd or 4th order active crossover filters for
each sub and satellite output, plus up to four parametric EQ filters for room
correction and tonal enhancement. With 400 watts available in bridged mode, there
is plenty of power on hand to fill any room with deep, gratifying bass.*
Active (powered) subwoofers are supported using the SWE-8 Sonnex Multiroom
Audio Unamplified Expander (sold separately).
* 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 140 watts @ 8 ohms, or two
additional zone outputs bridged to drive a subwoofer with 400 watts @ 8 ohms.

Unamplified Outputs
For applications requiring line level zone outputs, Crestron offers the SWE-8 Sonnex
Multiroom Audio Unamplified Expander (sold separately). Each SWE-8 provides an
assortment of analog line level, S/PDIF digital, and Crestron Home (CH) CAT5
balanced audio outputs, offering a solution for routing audio to AV receivers,
powered subwoofers, headphone amplifiers, phone systems (for music-on-hold), and
other audio equipment.
70/100 V Option
Any amplified zone output can be converted to 70- or 100-volt output using one or
more Sonnex Output Transformers (SAT-70V/100V-2 or SAT-70V/100V-4, sold
separately). A 70/100 V (constant-voltage) speaker system allows for the connection
of numerous speakers per circuit and long wire runs using small-gauge wire. Typical
applications include outdoor speaker zones, commercial retail spaces, hallways, and
common areas.
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 sent to a system touch screen or
mobile device, and integrators can even monitor and track the data remotely through
Crestron’s Fusion RV®software to ensure a rapid service response.
Ultimate Integration
Without question, Sonnex delivers unprecedented intelligence from source to
speaker. Via Cresnet®* 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.
* If using Cresnet as the control system interface, system expansion is limited to one expander. Support
for more than one expander requires Ethernet as the control system interface.
