Overview
JBL Synthesis
SDA-2200 and SDA-7120
Amplifiers
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.
