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.
Inphase connection
For optimum sound quality it is inevitable to connect speakers and amplifier inphase. I. e.,
within the respective channel (right or 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.
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 stereo output, with a clear, powerful bass sound. Make sure that each + termi
-
nal 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 distinguish + and -. If you
need to reverse the connections of one speaker to correct the phase, make sure the ampli
-
fier is turned off before you disconnect the speaker.
Make sure that the box that you want to set up to the right of the listening position is con
-
nected to the right channel on the amplifier, and the left box to the left channel.
