Connecting Loudspeakers
Step 1, ensure power is disconnected from the amplifier.
Step 2, using speaker cables, connect the red positive terminal of the right speaker output (R+) on the
amplifier to the positive (+) terminal of your right speaker.
Step 3, connect the black negative terminal of the right speaker output (R-) on the amplifier to the negative
(-) terminal of your speaker.
Step 4, repeat the process for the left speaker, using the terminals labelled L+ and L- and on the amplifier.
Top Tips
Check all connections thoroughly. Ensure that exposed wires or cables are not touching each other
or the amplifier’s chassis (which can cause a short circuit), and that you have connected the positive
(+) and negative (–) terminals correctly. Be sure to check the wiring for both the amplifier and the
speakers.
After making connections: switch the amplifier on with no input and reduce the volume to minimum.
Select a source signal, and then slowly increase the volume to a suitable listening level to avoid loud
sounds or product damage in the event of incorrect connection.
If you are unsure as to how your system should be connected, please contact your JBL dealer who
will be happy to help you.
