Connecting Speakers - Arcam AV860 Handbook

Connecting speakers

To connect each of the speakers, unscrew the
corresponding terminals on the back of the Receiver,

and screw the terminals back up. Make sure that the

It is important that no stray strands of wire from these
connections are allowed to touch another cable or the
product casing. Failure to ensure this can cause a short
circuit and damage your Receiver.
Do not over-tighten the loudspeaker terminals, or use a
wrench, pliers, etc., as this could damage the terminals
and this would not be covered under the product's
warranty.
Speaker cables
The speakers should be connected to the amplifier using
good-quality, high-purity, low impedance copper cables.
Cheap speaker cables should be avoided – they are a
false economy and can significantly degrade the sound
quality.
The cable runs to the speakers should be as short as
practicable. Connections to the speaker terminals
should always be finger tight, whether using bare wires
or spade connectors.
Bi-amping the Front Left & Front Right speakers
Bi-amping is the use of two amplifier channels per speaker. Bi-amping can
provide better sound quality than conventional single wiring. If you do not have

Surround Back speakers (i.e. you have a 5.1 surround system, not a 7.1 system)

then you can use the spare Surround Back speaker outputs to bi-amplify the
front left and right speakers, if your speakers support bi-amping. The spare
TRIG Z1 channels can alternatively be used to power stereo speakers in another room

(Zone 2).

Speakers that support bi-amping have two sets of +/- terminals per speaker,

To bi-amp the front left and right speakers, remove the metal strips from
the speaker terminals. Connect the woofer or LF terminals to the FL and FR
terminals on the Receiver. Connect the tweeter or HF terminals to the SBL and
SBR terminals on the Receiver. Finally, navigate to the Setup Menu 'Spkr Types'

Connecting subwoofers
The Receiver also allows up to two active subwoofer to be connected to the
outputs. Refer to your subwoofer handbook for the correct setting up and

Using external power amplifiers
The internal power amplifier of the Receiver (SR250
L, R, Sub only) can be supplemented or replaced with
external power amplification, such as the Arcam P49
(recommended gain 31dB). Connect the
sockets to your power amplifier inputs:
FL, FR
Connect these to the equivalent Right and Left front
channels of your power amplifier. For the SR250, only
this and the sub outputs are available

All preamplifier analogue outputs are buffered, have
a low output impedance and are at line level. They are
able to drive long cables or several inputs in parallel if
required.
