touch-screen controllers).
Network connector
Networking is a large subject and only the briefest
guidelines are presented in this handbook. Please
contact your Arcam dealer or specialist installer for
more information about introducing the AV950/
AVR750/450/380 into your computer network.
For information on how to use the AV950/
AVR750/450/380’s network features, the USB socket,
and for a list of supported file types, refer to see page
E-37.

Ethernet
If an Ethernet cable is connected, the AV950/
AVR750/450/380 will automatically attempt to connect
to your network.
You should use CAT5 cable plugged into the RJ45 socket
labelled
ETHERNET
on the rear panel.
If your network uses static IP addressing rather than
DHCP, you will need to provide IP address, gateway and
DNS; see page E-32 for information on setting up the
network.
USB connector
The AV950/AVR750/450/380 can play files stored on a
USB mass storage device, typically a pen drive, but any
USB device that complies with the ‘mass storage device‘
class is compatible.
The AV950/AVR750/450/380 only supports the direct
connection of USB devices and will not support devices
connected through a hub. If regular access to the
USB
socket is required, you may find it convenient to use
a USB extension lead; see page E-37 for details of
supported file types.

COMPONENT
The trigger connectors (
TRIG Z1
and
TRIG Z2
) provide an
electrical signal whenever the AV950/AVR750/450/380
is switched on and the relevant zone enabled.
The trigger signal can be used to switch on and off
compatible pieces of home entertainment equipment,
for example, you could set up a trigger to turn on
your television and BD player whenever the AV950/
AVR750/450/380 was switched on.
There are two trigger output sockets on the AV950/
AVR750/450/380, each capable of outputting a 12V,
70mA switching signal. The socket is designed for mono
3.5mm jacks: tip is the trigger output, sleeve is ground.
TRIG Z1
Use for remotely turning on and off power amps or
source equipment for Zone 1. On = 12V, Off = 0V.
TRIG Z2
Use for remotely turning on and off power amps or
source equipment for Zone 2. On = 12V, Off = 0V.

The infrared inputs (
Z1 IR
and
Z2 IR
) allow the
connection of external IR receivers, either when the
AV950/AVR750/450/380 front panel IR receiver is fully
or partially obstructed or to allow the use of a remote
control in Zone 2.
There are two IR inputs on the AV950/AVR750/450/380,
each designed for stereo or mono 3.5mm jacks. Tip is the
modulated signal, sleeve is ground.
Z1 IR
This input is intended for use with a local IR receiver
when the front panel of the AV950/AVR750/450/380 is
blocked.
NOTE
Sockets referring to ‘Z2’ relate to connections used
in multi-room installation. For more information on
these connectors see page E-38.
Z2 IR
This input is intended for use with an IR receiver
in Zone 2 to allow remote control of AV950/
AVR750/450/380 from a second room.
A supplier of infra-red receivers and emitter accessories
and systems is Xantech. See
www.xantech.com
for
more information, or ask your Arcam dealer.
NOTE
The IR inputs on the AV950/AVR750/450/380 are
designed for modulated signals. If the external IR
receiver demodulates the IR signal, it will not work.
Also the unit does not provide power for external
receivers on the IR jack, therefore an external power
source will be required.

speakers
The AVR750/450/380 allows you to connect up to seven
speakers and an active subwoofer in the main system.
The output channels correspond to speakers installed in
the front left, centre, front right, surround left, surround
right, surround back left, surround back right and an
active subwoofer.
The configuration and placement of your speakers
is very important
. All speakers, with the exception of
the subwoofer, should be arranged around your normal
viewing/listening position. The subwoofer should be
placed in a position which gives an even frequency
response in all listening positions. Incorrect placement
leads to bass boom in some areas. Often the only
way to find a good position for your subwoofer is by
experimentation. A good place to start experimenting
is close to a wall but at least 1m away from any corners.
You can also consult your subwoofer handbook for
placement suggestions.
Front left and right
Position your front left and right speakers to
achieve a good stereo image for normal musical
reproduction as well as for the multichannel
modes. If they are placed too close together there
will be a lack of spaciousness; if they are placed
too far apart a stereo image will appear to have a
large ‘hole’ in the middle and will be presented in
two halves. If there is no practical alternative to
placing the speakers widely apart, this effect can
be overcome in music reproduction by using the
centre sound extraction from the left and right
speakers (see Dolby Pro Logic II Music mode).
Centre
The centre speaker allows for a more realistic
reproduction of dialogue. The centre speaker
should have a similar tonal balance to the front
left and right speakers and be positioned at a
similar height.
Surround left and right
The surround left and right speakers reproduce
the ambient sound and effects present in a
multichannel home cinema system and should be
installed slightly higher than the listener’s ears.
Surround back left and right
The surround back left and right speakers
are used to add extra depth and better
sound localisation and should be installed
approximately one metre higher than the
listener’s ears. Place the two surround
back speakers such that there is an arc of
approximately 150 degrees between each
surround back speaker and the centre speaker.
The surround back speakers should face the front
of the room as shown in the diagram to provide
the largest ‘sweet spot’.
Subwoofer
A subwoofer will greatly improve the bass performance of your
system. This is useful for reproducing special cinema effects,
especially where a dedicated LFE (Low Frequency Effects)
channel is available, as with many discs encoded with Dolby or
DTS technologies.
More than one subwoofer unit may be required for larger
installations, particularly in rooms of a timber frame
construction. Multiple subwoofers will require a splitter cable
and need care in placement because there may be cancellation
effects between the units and you may require expert advice.
