Connecting speakers
To connect each of the speakers, unscrew the
corresponding terminals on the back of the Receiver,
insert the speaker wires through the hole in each post
and screw the terminals back up. Make sure that the
red (positive/+) terminal of the speaker is connected to
the red (positive/+) terminal on the back panel, and the
black (negative/–) terminal of the speaker is connected
to the black (negative/–) terminal on the back panel.

PREAMP OUT
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
e speakers should be connected to the amplier using
good-quality, high-purity, low impedance copper cables.
Cheap speaker cables should be avoided – they are a
false economy and can signicantly degrade the sound
quality.
e cable runs to the speakers should be as short as
practicable. Connections to the speaker terminals
should always be nger tight, whether using bare wires
or spade connectors.

Bi-amping the Front Left & Front Right speakers
Bi-amping is the use of two amplier 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 le and right speakers, if your speakers support bi-amping. e spare
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,
usually linked together by metal strips. ese metal strips MUST be removed
when bi-amping; failure to remove them will result in damage to the amplier
that is not covered under warranty.
To bi-amp the front le 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’
and set the ‘Use Channels 6+7 for’ menu option to ‘BiAmp L+R’; see page E-26.
Using external power amplifiers
e internal power amplier of the Receiver (SR250
L, R, Sub only) can be supplemented or replaced with
external power amplication, such as the Arcam P49
(recommended gain 31dB). Connect the PREAMP OUT
sockets to your power amplier inputs:

Height 1 and Height 2. Connect these to the Height 1
and/or Height 2 power amplier inputs.
All preamplier analogue outputs are buered, have
a low output impedance and are at line level. ey are
able to drive long cables or several inputs in parallel if
required.

e Receiver also allows up to two active subwoofer to be connected to the
SUB outputs. Refer to your subwoofer handbook for the correct setting up and
