A80/P80
5
This means that even though the power switch is off, it may
be possible to hear a slight hum coming from the mains
transformer inside the amplier. This is perfectly normal. If the
unit is to be left unused for an extended period, we recommend
that it is disconnected from the mains supply by switching it off
at the wall socket, or by disconnecting the power lead.
Connecting to other equipment
The use of high quality interconnect cables to and from your
amplier is recommended to ensure the best sound quality.
Sockets marked L (and R) on your amplier should only be
connected to sockets marked L (and R) on other equipment. All
the line inputs have the same sensitivity and may be used with
equipment other than that labelled, if needed.
LINE OUT
6
– Connect this output to the audio inputs of any
unit with a line-level input, e.g., tape deck, etc.
TAPE1/RECORD OUT
7
– Connect these output sockets
to the input sockets of your cassette deck (usually labelled
RECORD).
TAPE1/PLAY IN
8
– Connect these input sockets to the
output sockets of your cassette deck (usually labelled PLAY). If
you do not have a cassette deck you can use this input for other
(line level) equipment, such as a CD player, tuner, VCR, etc., but
not a turntable.
DVD
9
– Connect this input to the audio outputs of a DVD
player.
AV
bk
– Connect this input to the audio outputs of audiovisual
equipment such as a VCR, laserdisc player, satellite or Nicam
tuner.
TUNER
bl
– Connect this input to the audio outputs of your
radio tuner.
CD
bm
– Connect this input to the audio outputs of your CD
player or DAC (digital to analogue converter).
AUX
bn
– Connect this input to the audio outputs of any unit
with a line level output, e.g. tape deck, tuner, etc.
PHONO
bo
– Connect this input to the output of your record
player. This input provides RIAA equalization and is compatible
with most high output moving magnet (MM) cartridges.
Phono earth terminal – For connecting your turntable earth
lead (if tted). Note that this terminal must not be used as a
safety earth.
TRIG OUT AND REMOTE IN
3
(12V in and out) – These
connections are intended for use in multi-room installations.
TRIG OUT – This output provides a 12V signal whenever the unit
is switched on (i.e., not off or in standby). This signal can
be used to switch on automatically power ampliers (or
other equipment) connected to the A80, as they will come
on when the A80 is activated. This is useful if the power
amplier is remote from the A80, or otherwise difcult to
access. If you are bi-amping with a power amplier and
wish to power both units on or off simultaneously, see
page 10.
REMOTE IN – This allows remote control signals to be received
by the A80 if the remote sensor is covered (or otherwise
not ‘visible’ to the remote control). An external sensor is
used to receive the signals from the remote control, which
are then fed to the A80 (into this input) using a suitable
cable. Remote control signals acceptable to the A80
must be in modulated RC5 format, with a voltage level of
between 5V and 15V.
Note that in normal use there is no need to make any
connections to these sockets. If you would like to make use of
these features, please contact your dealer for more advice on
how to make the connections and on what type of cable to use.
Pre/power amplier connections
If you wish to use your A80 as a power amplier, please consult
your Arcam dealer.
PRE OUT
5
– To use your amplier as a pre-amplier,
connect the PRE OUT sockets to the input sockets of your
power amplier. With a power amplier of the correct gain (e.g.
the P80 power amplier) you can bi-amplify (‘bi-amp’) suitable
loudspeakers, giving signicant improvements in sound quality
(see page 12).
The different output types
The distinction between PRE OUT, LINE OUT and RECORD OUT
output types is subtle but important.
PRE OUT: This is the output that should be connected to your
power amplier. The output level varies with the volume
control.
LINE OUT: This output is taken before the volume control, i.e.,
the source being listened to is routed directly to this
output. If you wish, this output may be connected to a
recording device, such as a cassette recorder. Under
no circumstances should this output be connected to a
power amplier.
RECORD OUT: The output from the RECORD OUT connectors
is dependent on the conguation of the amplier. Full
instructions for this output are given on page 7; briey,
if the amplier is congured to ‘REC SOURCE’, then
this output will carry the same signal as the LINE OUT
connection. If the amplier is congured so that you are
recording a different source than the one you are listening
to, then the RECORD OUT connections will carry the
source being recorded.
