Connecting the Loudspeakers to the Amplifiers
In order to avoid damage of the speakers or other connected devices, please establish all
connections while the amplifier is switched off.
In phase connection
For optimum sound quality it is inevitable to connect speakers and amplifier in phase. I. e.,
within the respective channel (front right / left, centre, rear right / left)
- the „+ terminal” of the amplifier must be connected to the „+ terminal” of the box, and
- the „— terminal” of the amplifier must be connect to the „— terminal” of the box.
If the speakers are out of phase (i.e. the + terminal of one amplifier channel is connected to
the – terminal of one speaker, and the – terminal of one amplifier channel is connected to
the + terminal of one speaker), the sound will be affected and the speakers may be
damaged.
If the phase is reversed, the stereo image will be unstable, and the bass components will not
be clearly reproduced. Correctly connected (“in-phase”) speakers will give you a stable,
well-defined surround output, with a clear, powerful bass sound. Make sure that each +
terminal of the amplifier is correctly connected to the + terminals of the appropriate
speaker. Most speaker cables have one ridged or striped part, to help you disti and
-. If you need to reverse the connections of one speaker to correct the phase, make sure the
amplifier is turned off before you disconnect the speaker.
Make sure that the surround box that you want to set up to the rear right of the listening
position is connected to the right surround channel on the amplifier, and the rear left box to
the left surround channel.
