Placing The Unit; Interconnect Cables; Radio Interference - Arcam AV860 Manuel

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. 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 E-14).
<
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.
Power
The amplifier is supplied with a moulded mains plug
already fitted to the lead. Check that the plug supplied
fits your supply – should you require a new mains lead,
please contact your Arcam dealer.
If your mains supply voltage or mains plug is different,
please contact your Arcam 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 lead removed before changing the position of
the voltage range switch.
Push the IEC plug end of the power cable into the
socket on the back of the amplifier, making sure that it
is pushed in firmly. Plug the other end of the cable into
your mains socket and, if necessary, switch the socket
on.
The Receiver can be turned on using the POWER switch
on the front panel. While switched on, the front panel
LED will glow green.
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 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 mains
supply to save power.

Interconnect cables

We recommend the use of high-quality screened 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 mains 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 cabling, please refer to the
'Speakers' section, beginning on page E-15.

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 receiver as far as possible from
Receiver and its cabling.
<
Relocate the receiver with respect to the Receiver.
<
Connect the affected device and the Receiver to
different mains outlets.
If the problem persists, please contact your Arcam
dealer.
