CONNECTING TO OTHER EQUIPMENT
The use of high quality interconnect cables to and from your
integrated amplifier is recommended to ensure the best sound
quality (sonic performance).
The sockets carrying messages from your integrated amplifier are
marked L (left) and R (right), for identification. Sockets marked L
on your integrated amplifier should be connected to sockets
marked L on other equipment. All the line inputs (not PHONO)
have the same sensitivity and may be used with equipment other
than that labelled, if you need to do so.
bk
PROCESSOR/TAPE 1 RECORD OUT
Connect this output to the input sockets of your tape deck
(RECORD) or the tape or line input sockets of your AV processor.
bl
PROCESSOR/TAPE 1 PLAY IN
Connect this input to the output sockets of your tape deck
(PLAY) or the tape or line output sockets of your AV processor.
bm
VCR/TAPE 2 RECORD OUT
Connect this output to the input sockets of your tape deck
(RECORD).
bn
VCR/TAPE 2 PLAY IN
Connect this input to the output sockets of your tape deck
(PLAY).
bo
DVD
Connect this input to the audio outputs of a DVD player.
bp
AV
Connect this input to the audio outputs of an Audio-Visual
product such as a VCR, Laserdisc player or Nicam tuner.
bq
TUNER
Connect this input to the audio outputs of your radio tuner.
br
CD
Connect this input to the audio outputs of your CD player
or DAC (digital to analogue convertor).
bs
AUX
Connect this input to the audio outputs of any unit with a
line level output, eg. tape deck, tuner etc.
Please note:The AUX inputs MUST NOT be used if the
phono module is fitted. When the phono module is fitted
AUX becomes an output carrying the equalised phono
signal at line level.

PHONO OPTION - Please note:The phono inputs are on a
separate plug-in module which your Arcam dealer or
distributor can supply and fit.This module is compatible with
most high output moving coil and moving magnet cartridges
(MM) and low output moving coil cartridges (MC). MM or
MC is selected via an internal switch.Your cartridge type
should be specified when the module is fitted.
bt
MM
For connecting a turntable fitted with a high output moving
coil or a moving magnet (MM) cartridge.
ck
MC
For connecting a turntable fitted with a low output moving
coil (MC) cartridge.
cl
GROUND TERMINAL
For connecting your turntable earth lead (if fitted).

REMOTE CONNECTION
These connections are for use in multi-room installations. In
normal use there is no need to make any connections to
these sockets. If you are biamping with an Arcam power
amplifier see section 'Remote Switching' for details of how to
power both units on/off simultaneously.
8
GAIN
This switch allows you to change the sensitivity of the
amplifier to match the gain when biamping to external
power amp.The normal position is suitable for use when
biamping with Arcam power amplifiers.
The low gain position is suitable for certain specialist
home theatre systems. Before making any connections
ensure that all equipment is switched off at the mains wall
socket.

PRE/POWER CONNECTIONS
PWR AMP IN - To use your integrated amplifier just as a
power amplifier, connect the output of your pre-amplifier to
the PWR AMP IN sockets.The integrated amplifier's internal
selector switch must be changed to disconnect the pre-amp
stages of the unit. Contact your dealer or Arcam for more
details. Under these circumstances it has exactly the same
specification and performance as an Arcam power amplifier.
PRE-AMP OUT - To use your integrated amplifier as a
preamplifier, connect the PRE-AMP OUT sockets to the
input sockets of your power amplifier. With a power
amplifier of the correct gain (e.g. An Arcam P25)
this allows you to bi-amplify ('bi-amp') suitable loudspeakers,
giving significant improvements in sound quality (see section
on BI-WIRING/ BI-AMPING).

Bi-wiring your speakers

cl
Bi-wiring improves the sound of your system because it divides the
high and low frequency signal currents into separate speaker
cables.This avoids signal distortions arising from the high and low
PHONO OPTION
frequency currents interacting with one another within a single
MM
MC
L
cable, as in conventionally wired systems.
R
YOU WILL NEED
Speakers which have four terminals (connection points for
wires) on the back of each one. That's eight in total.
If you have four terminals on each speaker they will be marked HF
bt
(High frequency) and LF (Low Frequency).
Loudspeaker cables
Two pairs of loudspeaker cables per loudspeaker (which may be
joined at the amplifier end if your amplifier only has one pair of
output terminals per channel).
Or, a suitably terminated cable set (group of bound cables,
probably prepared by your dealer) capable of being used for
bi-wiring in one length.
WARNING
Do not make any connections to your amplifier while it is switched
on or connected to the mains supply. Please check all connections
thoroughly, make sure bare wires or cables are not touching the
amplifier in the wrong places (shorts) and you have connected
positive (+) to positive (+) and negative (-) to negative (-) before
attempting to re-connect the mains power supply.
Always ensure that the volume control on your amplifier is set to a
minimum before switching on.
HOW TO BI-WIRE LOUDSPEAKERS
1.
Remove the wire clips or bars which connect the pairs of terminals
together (terminal links) on each of the red and black terminals
on the rear of your loudspeakers.
THIS IS ESSENTIAL OR DAMAGE TO YOUR AMPLIFIERS
MAY RESULT WHICH IS NOT COVERED UNDER
WARRANTY.
2.
Connect the cables as shown in one of the pictures opposite,
dependant on the cables and the number of free amplifier
terminals you have, ensuring correct polarity at all times.
The positive (+) terminals on the right loudspeaker must go to the
positive (+) terminals on the right of the amplifier and the negative
(-) terminals on the right loudspeaker must go to the negative (-)
terminals on the right of the amplifier etc.

If you are using one pair of bi-wireable speakers and another pair
that is not, you should connect your bi-wireable speakers as shown
above, to just one set of the amplifier terminals. This leaves the
second set of terminals to connect the non bi-wireable speakers to.
