Trigger connectors
The trigger connectors ( & ) provide an
TRig Z1 TRig Z2
electrical signal whenever the amplifier 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 DVD player
whenever the unit was switched
on.
There are two trigger output
sockets on the unit, 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.
tip: Trigger output
sleeve: 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.
noTE
Sockets with the prefix 'Z2' refer to connections
used in multi-room installation. For more
information on these connectors, see page 54.
Infra-red (IR) connectors
The infra-red inputs ( and ) allow the
Z1 iR Z2 iR
connection of external IR receivers, either when
the unit's 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 unit, each designed for
stereo or mono 3.5mm jacks. Tip is the modulated signal,
sleeve is ground.
tip: Modulated signal
sleeve: Ground
Z1 IR
This input is intended for use with a local IR receiver
when the front panel of the unit is blocked.
Connecting an IR receiver to will disable to front
Z1 iR
panel IR receiver to prevent problems with multiple
commands if the front panel IR receiver is only partially
obstructed.
Z2 IR
This input is intended for use with an IR receiver in
Zone 2 to allow remote control of the unit from a second
room.
IR OUT
This output is an electrical
combination of the Z1 (or front
panel) + Z2 infra-red signals
above. It can be used to drive
external IR emitters or can be
connected directly to other
Arcam equipment which have
an IR input. This function can
be useful as an IR 'repeater' so
that someone in any of the zones
can control the functions of a
CD player in the main zone, for
example. Tip is the modulated
electrical IR signal, sleeve is ground.
A supplier of infra-red receivers and emitter accessories
and systems is Xantech. See www.xantech.com
more information, or ask your Arcam dealer.
NOTE
The IR inputs on the unit 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.
