e AV950/AVR750/450/380 receivers are designed
to produce a level of performance that will truly bring
music and movies to life.
e AV950, AVR380, AVR450 and AVR750 are
high-quality and high-performance home-cinema
processors and ampliers built to Arcam’s quality
design and manufacturing standards. ey combine
digital processing with high-performance audio and
video components to bring you an unrivalled home-
entertainment centre.
e AV950/AVR750/450/380 allows switching and
control of seven analogue and six digital audio sources
in addition to internal FM (and, in the case of the
AVR450, AVR750 and AV950, DAB) radio – as well as
networked and USB audio sources – making any of the
models an ideal hub for both home-cinema and two-
channel stereo systems.
Since many of these source components are also capable
of generating video signals, the AV950/AVR750/450/380
includes broadcast-quality switching for HDMI,
Composite and Component video signals. Control of the
AV950/AVR750/450/380 is either by front panel control
buttons, IR remote control or RS232 port.
e CR450 remote control supplied with the AV950/
AVR750/450/380 is a twelve-device ‘universal’ learning
remote control which is simple to use, and once set up is
able to control a complete system. It can be programmed
using its vast internal code library to control CD and BD
players, PVRs, TVs and other devices.
e installation of the AV950/AVR750/450/380 in a
listening room is an important process which requires
care at every stage. For this reason, the installation
information is very comprehensive and should be
followed carefully to achieve an unrivalled level of
performance.

AVR750
Placing the unit
< Place the unit on a level, rm surface, avoiding
direct sunlight and sources of heat or damp.
< Do not place the AV950/AVR750/450/380 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 AV950/
AVR750/450/380 will run warm during normal
operation.
< Do not place any other component or item on top of
theamplierasthismayobstructairowaroundthe
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-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
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 AV950/AVR750/450 can be switched for operation
between 220–240V (switch position 230V) and
110–120V (switch position 115V).
NOTE
Ensure that the AV950/AVR750/450 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 AV950/AVR750/450/380 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 AV950/AVR750/450/380 can be switched into
standby mode using the
P
button on the CR450
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-15.
Radio interference
e AV950/AVR750/450/380 is an audio device
containing microprocessors and other digital
electronics. Each model 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 AV950/AVR750/450/380 causes interference to
radio or television reception (which can be determined
by switching the AV950/AVR750/450/380 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
AV950/AVR750/450/380 and its cabling.
< Relocate the receiver with respect to the AV950/
AVR750/450/380.
< Connect the aected device and the AV950/
AVR750/450/380 to dierent mains outlets.
If the problem persists, please contact your Arcam
dealer.
