Connecting the leads (supplied)

Connecting the speaker leads

The speaker output mode can be two-channel (stereo), one-

channel (mono), or three-channel (stereo + mono}. Connect

the speaker leads to suit the mode. To connect the speaker

leads to the speaker terminals of the amplifier, see the

connection diagram for each channel. Be careful with the

polarity (+ and -}, and with which channel ts which (left [L]

and right [R]).

• If the amplifier is used in three-channel mode, inductors

and capacitors are needed. For more information, see

"Three-channel mode (stereo + mono)".

diagram, please have the work done by your nearest authorized

Pioneer installation specialist.

Three-channel mode (stereo + mono)

The power amplifier is basically a two-channel/one-channet

bridgeable amplifier, but three channels can be achieved by

combining the stereo and mono modes using inductors

and capacitors. Some typical examples are given below.
