Placing the unit
Place the unit on a level, firm surface, avoiding direct
sunlight and sources of heat or damp.
Do not place the Receiver 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 (see page EN-2). The
Receiver will 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.)
Make sure the remote-control receiver on the front
panel display is unobstructed, otherwise this will
impair the use of the remote-control. If line-of-sight
is impractical, a remote-control repeater can be used
with the rear panel connector (see page EN-34).
Do not place your turntable on top of this unit.
Turntables are very sensitive to the noise generated
by mains power supplies which will be heard as a
background 'hum' if the turntable is too close.
Power
The amplifier is supplied with a molded AC plug already
attached to the cord. Check that the plug supplied fits
your outlet – should you require a new power cord, please
contact your JBL Synthesis dealer.
If your AC voltage supply or power cord is different, please
contact your JBL Synthesis dealer immediately.
The Receiver can be switched for operation between
220–240V (switch position 230V) and 110–120V (switch
position 115V).
NOTE: Ensure that the Receiver 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.
The Receiver can be turned on using the power switch on
the front panel. While switched on, the front panel LED will
glow white.
Standby power
The Receiver can be switched into standby mode using
the 2 button on the remote control. While in standby mode
the front panel LED will glow red and (with default settings)
power consumption is less than 0.5 Watts.
While in Standby mode, it may be possible to hear a slight
residual hum coming from the mains transformer inside the
amplifier. This is perfectly normal. However, if the unit is to be
left unused for an extended period, we recommend that you
disconnect it from the AC outlet to save power.
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, please refer to the
'Speakers' section, beginning on page EN-16.
EN-7
Radio interference
The Receiver is an audio device containing microprocessors
and other digital electronics. Each model has been designed
to very high standards of electromagnetic compatibility.
This is a Class A product. In a domestic environment this
product may cause radio interference, in which case the user
may be required to take adequate measures.
If the Receiver causes interference to radio or television
reception (which can be determined by switching the
Receiver off and on), the following measures should
be taken:
Re-orient the receiving antenna or route the antenna
cable of the affected device as far as possible from the JBL
Synthesis Receiver and its cabling.
Relocate the affected device with respect to the JBL
Synthesis Receiver.
Connect the affected device and the Receiver to different
mains outlets.
If the problem persists, please contact your JBL Synthesis
dealer.
