Connecting Loudspeakers
There are many different ways of connecting
loudspeakers to your SA10/SA20 amplifier. The following
section describes how to connect the speakers and
amplifier for the most common configurations.
Single Wiring
If each speaker has more than one pair of connecting
LET
terminals, use the terminals labelled 'LF' or 'Low
Frequency' on your speakers.

VOLTAGE
Connect the red positive terminal of the right speaker
connection on the amplifier (labelled R+) to the positive
terminal of your right speaker. Similarly, connect the

on the amplifier (labelled R-) to the negative terminal
of your speaker. Repeat the process for the left speaker,
using the terminals labelled L+ and L- on the amplifier.
WARNING: If your speakers support bi-wiring, there
will be a strip of conductive metal connecting the low-
frequency (LF) terminals to the high-frequency (HF)
terminals; this MUST NOT BE REMOVED in a single-
wired system.

Notes On Making Speaker Connections
Do not make any connections to any amplifier while it is switched on. We recommend that your amplifier is
completely disconnected from the mains supply before starting.
Before switching your amplifier on for the first time after connecting to speakers, please check all connections
thoroughly. Ensure that bare wires or cables are not touching each other or the amplifier's chassis (which could
cause short circuits), and that you have connected positive (+) to positive and negative (–) to negative. Be sure to
check the wiring for both the amplifier and the speaker.
After making connections: switch the amplifier on, select a source signal, then gradually increase the volume to
the required listening level.
If you are unsure as to how your system should be connected, please contact your Arcam dealer who will be
happy to help you.
