Trigger connectors
The trigger connectors ( TRig Z1 , TRig Z2 and TRig Z3 )
provide an 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 three 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.
Infra-red (IR) connectors
The infra-red inputs ( Z1 iR , Z2 iR
and Z3 iR ) allow the 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 or Zone 3.
There are three 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
Z1 iR will disable to front
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.

Z3 IR
This input is intended for use with an IR receiver in
Zone 3 to allow remote control of the unit from a third
room.
IR OUT
This output is an electrical combination of the Z1 (or
front panel) + Z2 + Z3 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 for
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.
TRIG Z3
Use for remotely turning on and off power amps or
source equipment for Zone 3. On = 12V, Off = 0V.
noTE
Sockets with the prefix ‘Z2’ or ‘Z3’ refer to
connections used in multi-room installation. For
more information on these connectors, see page 48.
