Welcome
Thank you and Congratulations...
The JBL Synthesis SDA-2200 and SDA-7120 deliver dynamic Class G amplification with modern network capability,
audiophile sound and exceptional flexibility. With balanced and single ended inputs, RS232 and IP control as well
Dante™ audio networking, the SDA-2200 and SDA-7120 are superb choices for a broad range of applications.
Class G offers greater efficiency and transparency, with less wasted heat energy than Class A. Like a hybrid car engine,
Class G implements multiple power supplies. The first power supply runs in pure Class A, which has no crossover
distortion. If a dynamic signal is received that goes beyond the capability of this first power supply, the secondary
supply is gradually incorporated up to full rated power output as required. This efficient design means additional
power is only used when required. Modern high-speed silicon allows this switch to take place well beyond the audio
bandwidth. Multiple output devices within the amplifier ensure your listening experience is powerful, dynamic and
crystal clear.
The SDA-2200 and SDA-7120 feature Dante™ audio networking so you can connect with the JBL Synthesis
SDR-35 AVR and SDP-55 immersive surround sound processor as well as other Dante-enabled products over
Ethernet-based networks via Cat5e or Cat6 cable. Dante audio networking uses standard IP networks to
transmit high-quality, uncompressed multi-channel audio with near-zero latency. It is flexible, reliable, and
easy-to-manage and eliminates issues with interference, crosstalk and signal degradation associated with
analog cable.

Overview
JBL Synthesis
SDA-2200 and SDA-7120
Ampliers
JBL Synthesis SDA-2200 and SDA-7120 power amplifiers
provide exceptional sound quality for the best
reproduction of your music.
Drawing many years of amplifier design experience,
these products use the best quality components and
engineering practice to produce amplifiers that will
give many years of musical pleasure and reliable service.
With a toroidal based power supply, acoustically damped
chassis, Class G technology and exceptionally low levels
of distortion and noise, the SDA-2200 and SDA-7120
amplifiers are all capable of reproducing music with all
its original detail.
Placing the Unit
Place the amplifier on a level, firm surface, avoiding
direct sunlight and sources of heat or damp.
Do not place the SDA-2200 or SDA-7120 on top of a
power amplifier or other source of heat.
Do not place the amplifier in an enclosed space such
as a bookcase or closed cabinet unless there is good
provision for ventilation. The SDA-2200 and SDA-7120
are designed to run warm during normal operation.
Do not place any other component or item on top
of the amplifier as this may obstruct airflow around
the heat-sink, causing the amplifier to run hot. (The
unit placed on top of the amplifier would become
hot, too).
Power
The amplifier is supplied with a molded AC plug already
attached to the cord. Check that the plug supplied fits
your outlet.
If your AC voltage supply or power cord is different,
please contact your JBL Synthesis dealer immediately.
The amplifier can be switched for operation between
220–240V (switch position 230V) and 110–120V (switch
position 115V).
Note: Ensure that the amplifier is switched OFF and the
power cord removed before changing the position of
the voltage range switch.
Push the IEC plug end of the power cord into the
socket on the back of the amplifier, making sure that it
is pushed in firmly. Plug the other end of the cord into
your AC outlet.
Do not place your record deck on top of this
unit. Record decks are very sensitive to the noise
generated by mains power supplies which will be
heard as a background ‘hum’ if the record deck is
too close.
The normal function of the unit may be disturbed by
strong electromagnetic interference. If this occurs,
simply reset the unit with the power button, or move
the unit to another location.
Interconnect Cables
We recommend the use of high-quality shielded cables
that are designed for the particular application. Other
cables will have different impedance characteristics
that will degrade the performance of your system (for
example, do not use cabling intended for video use to
carry audio signals). All cables should be kept as short as
is practically possible.
It is good practice when connecting your equipment to
make sure that the AC power-supply cabling is kept as
far away as possible from your audio cables. Failure to
do so may result in unwanted noise in the audio signals.
For information on speaker cables, see “Connecting
Sources and Loudspeakers” on page EN-12.

it changes from red to orange then white if mains
power is connected and the unit is switched on.
Pressing the STANDBY button while the unit is powered
on, will place the SDA-2200 or SDA-7120 into standby
mode. Press the STANDBY button again to bring the
unit out of standby.
Automatic Standby
In order to comply with international regulations for
consumer products, this unit is designed to enter
standby mode if no user interaction and no audio input
signal are detected for an extended period of time
(default is 20 minutes). The unit can be brought out of
standby by pressing the STANDBY button on the front
panel, the trigger input or RS232 or Ethernet command.
The standby time out can be adjusted using either
RS232 or IP control commands. Please refer to the
SDA-2200 / SDA-7120 RS232/IP control document,
available for download from www.jblsynthesis.com.
Alternatively, pressing and holding the MUTE button
for more than 3 seconds will toggle the standby time-
out between OFF and 20 Min.
Note: If the standby time-out is set to OFF, the automatic
standby feature will be disabled.
Network and RS322 in Standby
In low power standby mode the network and RS322
functionality is disabled. To enable network and RS232
in standby, send a control or status request command
to the unit while it is powered on. This will enable
whichever control method was used when the unit is
in standby.
Note: To indicate the unit is not in lowest power
standby mode the LED will flash briefly when entering
standby mode.
Note: Enabling network or RS232 control will increase
standby power consumption. To restore the unit to the
default low power standby consumption press and
hold the STANDBY button for more than 3 seconds.
Dante Ports
Dante is a licensed technology from Audinate®. It uses
standard Internet protocols over a 100Mb or gigabit
network and is capable of transporting professional-
quality, low-latency audio. Dante runs on standard
computer networking hardware and does not require
dedicated network infrastructure; Ethernet switches
transmit Dante digital media streams alongside ordinary
data traffic. The physical Dante connections must be
made using Cat5e or Cat6 cables 100m/328ft between
devices when using a gigabit network. The two Dante
(RJ-45) ports on the back of the SDA-2200 and SDA-
7120 can be used to receive high resolution digital
audio from Dante enabled transmitting devices such
as the JBL Synthesis SDR-35 AVR and SDP-55 surround
sound processors.
Dante-enabled devices connected to the same
network
Dante is configured and controlled using the Dante
Controller software whi ch is a free download for
Windows or Mac OS and can be downloaded at
www.audinate.com/products/software/dante-controller.
Dante works independently of the unit control. Be
sure to use the Dante jacks only for Dante networking
applications. For more information on Dante, please
visit www.jblsynthesis.com .
Mode Switches
The various mode switches located on the rear of
the SDA-7120 and SDA-2200 amplifiers allow you
to configure your power amplifier to your specific
equipment setup. See “Connecting Sources and
Loudspeakers”on page EN-12 for more information.
INPUT (SDA-7120 and SDA-2200 only)
This switch selects between the XLR and RCA phono
inputs of the amplifier. Select which ever connection
method you are using to connect your preamp.
GAIN(SDA-2200 only)
This switch allows the gain to be changed from standard
JBL Synthesis gain of 31dB (which matches all JBL
Synthesis amplifiers and receivers) to 26dB. This allows
flexibility to connect multiple SDA-2200 amplifiers in
different modes to multiple speakers.
In normal set-ups this switch should be left at 31dB.
MODE (SDA-2200 only)
This switch selects between the different amplification
modes of the SDA-2200.
STEREO (ST)
This is the standard stereo amplification mode using
two separate preamp inputs driving two separate
speaker outputs.
DUAL MONO (DM)
This mode allows two separate speakers to be driven
from a single preamp input. Alternatively the two
drivers of a single speaker can be bi-amped from a
single SDA-2200.
BRIDGED MONO (BRIDGE)
This mode uses both channels of the SDA-2200 to drive
a single speaker. This the ultimate in high power, high
fidelity amplification.
Muting the Output
The speaker outputs of the SDA-2200 or SDA-7120 can
be silenced by pressing the MUTE button on either the
front panel or by sending the relevent command via
either the RS232 or network connection.
If the unit is muted, front panel power indicator will
change to orange. To cancel the mute, press the MUTE
button again or send the relevent command via either
the RS232 or network connection.

Notes on Making Speaker Connections
Do not make any connections to any amplifier while it is switched on. We recommend
that your amplifier is completely disconnected from the mains supply before starting.
Before switching your amplifier ON for the first time after connecting to speakers, please
check all connections thoroughly. Ensure that bare wires or cables are not touching
each other or the amplifier’s chassis (which could cause short circuits), and that you
have connected positive (+) to positive and negative (–) to negative. Be sure to check
the wiring for both the amplifier and the speaker.
After making connections: switch the amplifier ON then gradually increase the volume
to the required listening level.
If you are unsure as to how your system should be connected, please contact your JBL
Synthesis dealer who will be happy to help you.

Dual Mono / Bi Amp Mode – SDA-2200 Only
Dual mono requires the use of a SDA-2200 for each
channel.
On one of the SDA-2200’s, connect the RED positive
speaker terminal labelled L+ to the positive LF terminal
of your left speaker. Similarly, connect the BLACK
negative speaker terminal labelled L- to the negative LF
terminal of your left speaker.
WARNING: Speakers that support bi-amping
have a metal strip that connects the low
frequency (LF) and high frequency (HF)
terminals. This MUST be removed in a bi-
amped system
Using a second speaker cable connect the RED positive
speaker terminal labelled R+ to the positive HF terminal
of your left speaker. Similarly, connect the BLACK
negative speaker terminal labelled R- to the negative
HF terminal of your speaker.
Repeat this process for the right speaker, using the same
terminals on the other SDA-2200.
In this setup only one interconnect is required to
each power amplifier and it should be connected to
the IN L input. The interconnects can be either XLR
(recommended for longer cable runs) or phono (RCA).
Set the INPUT switch on both of the SDA-2200’s to the
appropriate setting for the cables used.
Note: The IN R input has no function in this
arrangement.
Note:
Make sure INPUT switch
is set to input type RCA
or XLR
Make sure GAIN switch is
set to 31dB.
Make sure MODE switch
is set to dual mono
mode, DM.

Troubleshooting
Problem Check the following
No sound The SDA-2200 / SDA-7120 power amplifier is correctly plugged in and
switched on.
Your audio/video source (e.g. pre amplifier) is correctly connected.
The SDA-2200 / SDA-7120 is not in protection mode, as described in
the next section.
The SDA-2200 and SDA-7120 is not muted.
Sound cuts-out unexpectedly The SDA-2200 / SDA-7120 may enter a protection mode, depending on
the fault being detected. The front panel LED will indicate the fault type,
according to the list below.
FLASHING WHITE: The internal temperature of the unit reached an
unsafe level. Allow the SDA-2200 / SDA-7120 to cool off.
FLASHING RED: The SDA-2200 / SDA-7120 amplifier detected a
speaker short circuit. Should this happen, please inspect all the
speaker cables to make sure none of them are shorted together. This
fault is very common when bare wires are being used to make speaker
connections.
FLASHING ORANGE: SDA-7120 and SDA-2200 only. The amplifier
detected a DC offset.
Following any of the faults described above, the amplifier will turn itself
OFF and power to the speakers will be removed. To continue using the
SDA-2200 / SDA-7120, the fault must be removed and the unit must be
turned OFF then back ON.
