English
Placing the unit
< Place the unit on a level, firm surface, avoiding
direct sunlight and sources of heat or damp.
< Do not place the unit on top of a power amplifier or
other source of heat.
< Do not place the unit in an enclosed space such as
a bookcase or closed cabinet unless there is good
provision for ventilation. The unit 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 17).
< 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 amplifier can be switched for operation between
195–265V (switch position 230V) and 85–132V (switch
position 115V).
NOTE
Ensure that the unit 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 amplifier 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 unit can be switched into standby mode using
the 2 button on the CR102 remote control. While in
standby mode the front panel LED will glow red and
power consumption is around 3 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 23.
Radio interference
The AVR500, AVR600 and AV888 are audio devices
containing microprocessors and other digital
electronics. They have 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 unit causes interference to radio or television
reception (which can be determined by switching the
unit 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
the unit and its cabling.
< Relocate the receiver with respect to the unit.
< Connect the affected device and the unit to different
mains outlets.
If the problem persists, please contact your Arcam
dealer.
