Home cinema systems using subwoofer/satellite combinations are becoming increasingly
popular because their convenient size makes them easy to configure (Fig. 5). These systems
are normally wired as shown in Fig. (3); however, please study the instructions of your Dolby
surround sound decoder carefully before actually making the connections.
BI-WIRING AND BI-AMPING
In conventional systems the speaker connection cables carry all the frequencies together. The
bass signals have much more power, however, and this can cause losses in overall sound
quality. „Bi-wiring", which means dividing the signal and using one set of cables for the high
frequencies and another for the basses, can bring an audible improvement in sound quality.
„Bi-amping" goes one step further by using separate amplifiers as well as separate cables for
the high and low frequency ranges. This method eliminates sound losses caused by the
widely-different current levels in the lower and upper frequency ranges by separating the
signals right from the very start.
MAGNAT speakers have specially-designed connection terminals that can be used both for
conventional operation and for bi-wiring/bi-amping. This means that lf you wish, you can
use separate connections for the woofer and the mid/tweeter units. There are four screw
terminals on each speaker: the top two are for the mid-range and tweeter units, the bottom
two for the woofers. When the speakers are delivered from the factory the upper and lower
terminals are connected with jumpers for operation in conventional mode (see above). lf you
just wish to use one cable simply leave the jumpers in place and connect the cable to either
the upper or the lower terminals - which pair you use makes no difference (Fig. 6).
lf you wish to operate the speakers in bi-wiring/bi-amping mode you must first remove the two
jumpers from each speaker.
For bi-wiring you need two cables for each speaker and amplifier channel, or a special bi-
wiring cable. Connect the two cables to the amplifier outputs in parallel - i.e. connect both
positive leads to the positive output terminal and both negative leads to the negative output
terminal. Then connect the other ends of one cable to the mid/tweeter terminals and those of
the other cable to the woofer terminals on the speaker (Fig. 7).
A bi-amping setup uses two amplifiers, with the first handling the mid and high range frequencies
and the second the low range. The correct connections are very important: Connect the left
output of the first amplifier to the upper terminals of the left speaker, and the right output of the
same amplifier to the upper terminals of the right speaker. Proceed in the same way to connect
the outputs of the second amplifier to the lower terminal pairs on the speakers (Fig. 8).
