Placing the unit
< Place the unit on a level, rm surface, avoiding
direct sunlight and sources of heat or damp.
< Do not place the AVR400 on top of a power
amplier or other source of heat.
< Do not place the amplier in an enclosed space
such as a bookcase or closed cabinet unless there is
good provision for ventilation. e AVR400 will run
warm during normal operation.
< Do not place any other component or item on top of
the amplier as this may obstruct airow around the
heat-sink, causing the amplier to run hot. (e unit
placed on top of the amplier 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
e amplier is supplied with a moulded mains plug
already tted to the lead. Check that the plug supplied
ts your supply – should you require a new mains lead,
please contact your Arcam dealer.
If your mains supply voltage or mains plug is dierent,
please contact your Arcam dealer immediately.
e AVR400 can be switched for operation between
195–265V (switch position 230V) and 85–132V (switch
position 115V).
NOTE
Ensure that the AVR400 is switched o 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 amplier, making sure that it
is pushed in rmly. Plug the other end of the cable into
your mains socket and, if necessary, switch the socket
on.
e AVR400 can be turned on using the
POWER switch
on the front panel. While switched on, the front panel
LED will glow green.
Standby power
e 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 amplier. is is perfectly normal. However,
if the unit is to be le 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 dierent 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
e AVR400 is an audio device containing
microprocessors and other digital electronics. It has
been designed to very high standards of electromagnetic
compatibility.
is 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 o and on), the following measures should be
taken:
< Re-orient the receiving antenna or route the antenna
cable of the aected receiver as far as possible from
AVR400 and its cabling.
< Relocate the receiver with respect to the AVR400.
< Connect the aected device and the AVR400 to
dierent mains outlets.
If the problem persists, please contact your Arcam
dealer.
