Bi-wiring

If you are using bi-wiring, remove the “bridges” between

the two sets of terminals.

You can connect the cables together to one set of output

terminals on the amplifier, or, if the amplifier has two sets

of output terminals, connect one cable to terminal set “A”

and the other cable to terminal set “B”.

Bi-amping

In bi-amping the loudspeakers are connected to two power amplifiers.

Here you have two options:

1. Connect amplifier “1” to the tweeter/midrange.

Connect amplifier “2” to the woofer.

(When different amplifiers are used).

- or -

2. The two amplifiers are used for the left and right channels, respectively, i.e. the tweeter/midrange units are connected to one

channel on the amplifier, and the woofer is connected to the other. (Typically when identical amplifiers are used)

Consult your Jamo dealer for further information.

Always make sure that the loudspeakers are in proper phase;

The + terminal on the loudspeaker is connected to the + terminal on the amplifier.

The - terminal on the loudspeaker is connected to the - terminal on the amplifier.

Loudspeaker cable is usually marked on one cord; this cord is normally used to connect the + terminals, this way it is easy to ensure that

the loudspeakers are in correct phase.
