Placing The Unit; Interconnect Cables; Radio Interference - Arcam AVR400 Handbuch

Placing the unit

Place the unit on a level, firm surface, avoiding
<
direct sunlight and sources of heat or damp.
Do not place the AVr400 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 AVr400 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-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 AVr400 can be switched for operation between
220–240V (switch position 230V) and 110–120V
(switch position 115V).
NOTE
Ensure that the AVr400 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 AVr400 can be turned on using the switch
POWER
on the front panel. While switched on, the front panel
LED will glow green.
Standby power
The AVr400 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 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-18.

Radio interference

The AVr400 is an audio device containing
microprocessors and other digital electronics. It 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 AVr400 causes interference to radio or television
reception (which can be determined by switching the
AVr400 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
AVr400 and its cabling.
relocate the receiver with respect to the AVr400.
<
Connect the affected device and the AVr400 to
<
different mains outlets.
If the problem persists, please contact your Arcam
dealer.
