Connection Of The Loudspeaker - ELAC 4 PI PLUS.2 Bedienungsanleitung

Connection of the loudspeaker

Page 8 von 12
There are 2 loudspeaker terminals with cables on the rear of this add-on tweeter. This enables the connection to main
speakers. Connect the 4 PI PLUS.2 in parallel to the main speaker. Connect the " +" pole of the add-on tweeter to the
"+" pole of the main speaker. Do the same with the negative pole "-" (see figure A).
If the main speaker is provided with a bi-wiring terminal with 4 input sockets, always 2 input sockets are connected in
parallel when cable suspension bridges are used. In this case, the cable of the 4 PI PLUS.2 can be connected to the
other pair of input sockets (see figure B).
If the main speaker is operating in bi-wiring mode, (i. e. two cable pairs run from the amplifier, cable suspension
bridges are opened) the 4 PI PLUS.2 must be connected to the tweeter unit of the main speaker (see figure C).
It is also possible to connect the 4 PI PLUS.2 directly to the amplifier.
If your amplifier offers 2 loudspeaker terminals, the second terminal can be used for the ELAC 4 PI PLUS.2. In this
case, you have to adjust the selector switch for loudspeakers on your amplifier (e.g. speakers A + B). This way, the 4
PI PLUS.2 can be easily switched on/off.
Cables with a length of approx. 4 meters should provide a cross-section of 2 x 1.5 qmm. Cables with increased lengths
should provide a cross-section of 2 x 2.5 qmm. For low-resistance main speakers, it is recommended to use cables
with a cross-section of 2 x 4 qmm.
It is recommended, to use low-inductance cables. Cables with a low-inductance structure provide several tight, cross-
wise interwined conductors and return conductors. The ELAC 4 PI PLUS.2 should be used with this certain type of
cable when long cable lines are required.
