Arcam P75 - Manual (Page 8)

A65/A75/P75
8
The P75 power amplifi er can be used in conjunction with
the A65 and A75 integrated amplifi ers (or other Arcam
amplifi ers) to bi-amplify loudspeakers that have two pairs of
input connections (i.e. are bi-wireable). The P75 can also be
used with a pre-amplifi er such as the Arcam 9C or an AV
processor or amplifi er with
PRE-AMP OUT sockets.
Loudspeaker connections
Connect up following the instructions for installing the A65 and
A75 integrated amplifi ers (see page 4).
Connecting to other equipment
PWR AMP IN 5
Connect these sockets to your preamplifi er output sockets.
Alternatively, if you are using an integrated amplifi er (as your
pre-amp) such as the A65, A75 or Alpha series amplifi ers,
connect the
PWR AMP IN sockets to the PRE AMP OUT sockets
on those amplifi ers.
MONO LINK 6
The P75 can be adapted to provide two mono loudspeaker
outputs from a single input.
Pull out the U-link 8 supplied and use it to connect the
MONO LINK sockets 6 together.
Installation: P75 power amplifi er
SP1 DIRECT terminals 3
Are switched off when a headphone jack plug is inserted in
the headphone socket
bk on the front of the amplifi er or, by
pressing the MUTE button ( ) on the remote control handset.
SP2 9
Push the button in to select the loudspeakers connected to
the SP2
4 speaker terminals. To disconnect the speakers,
release the switch again.
HEADPHONE socket bk
Accepts headphones rated between 8 Ω and 2kΩ fi tted with
a 6.3mm stereo jack plug. If your headphones are fi tted with
a different plug contact your dealer for a suitable adaptor.
Inserting a headphone jack plug automatically mutes (i.e. cuts
off) the loudspeakers.
POWER bl
Switches the amplifi er on and off.
Power indicator bm
This initially glows orange. After a few seconds, the colour
changes to green and a slight click may be heard as the output
muting relay disengages.
When the indicator glows orange, the speakers are
disconnected and an internal protection circuit is working.
If the indicator glows orange during normal use it may be due
to an amplifi er output overload. Switch the amplifi er off and wait
for 2–3 minutes before switching on again.
If the indicator continues to glow orange, switch the unit off,
remove all the speaker cables and switch on again. If the
indicator goes green on switching on, there is a problem
with the speakers or speaker cables. Check the speakers and
speaker cables for short circuits before reconnecting them.
If the indicator continues to glow orange with no speakers
connected, contact your Arcam dealer.
Utilising one P75 power amplifi er per loudspeaker will enable
you to bi-amplify bi-wireable loudspeakers. This is particularly
benefi cial for top quality stereo installations with a separate pre-
amplifi er, or for the left, centre and right channel loudspeakers
in a fi ve speaker Dolby Pro Logic™ or Dolby Digital™ system.
Contact your Arcam dealer for more detailed information.
DAISY CHAIN
The P75 is capable of driving further P75 amplifi ers (or any
other power amplifi er), to drive more speakers (e.g. those in
other rooms or tri-amplifi ed speakers etc). Connect the extra
power amplifi er inputs to the
MONO LINK outputs 6 left to
left, right to right with suitable high quality phono to phono
cables.
Connecting to a power supply
Connect up following the instructions for installing the A65 and
A75 integrated amplifi ers (page 4).
CIM MODULE 7
The CIM (custom install module) is an optional module that
enables you to adjust the gain of the left and right channels
of the power amplifi er independently and also to switch the
power amplifi er on/off remotely, with a 12 volt trigger. The CIM
module would normally be used in a multi-room set up. When
a CIM module is fi tted into a power amplifi er, the front panel
power switch is disabled.
See your Arcam dealer for further information.
