CONNECTING LOUDSPEAKERS
There are many different ways of connecting
loudspeakers to your SA750 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 terminals, use the terminals labelled
" " or "
Low Frequency
" on your speakers.
Connect the red positive terminal of the right
speaker connection on the amplifier (labelled )
to the positive terminal of your right speaker.
Similarly, connect the black negative terminal
of the right speaker connection on the amplifier
(labelled ) to the negative terminal of your
speaker. Repeat the process for the left speaker,
using the terminals labelled
and
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 JBL dealer
who will be happy to help you.
