Operation
Switching On
The
POWER
button switches the unit ON and OFF. The
status indicator LED indicates the state of the amplifier:
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 which 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

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.
