4-Ch. Amplifier - 5-Ch. Mode

A 3-way system with front stage, rear stage and subwoofer in mixed mono
configuration. The 5-speakers system requires a passive crossover between the
front highs and the mono woofer, with capacitors on the front highs positives and
a coil on the woofer positive. All amplifiers channels are full range.

4-Ch. Amplifier - Stereo Mode

A simple 4 channels hookup for a right and left stereo pair. This is the standard
hookup for full range front and rear speakers.

4-Ch. Amplifier - High Power 2-Ch. Mode

Want more power? Instead of 4 channels of 150 watts, you can have two channels
of 500W each by bridging both front and rear amp sections to one speaker each.

2-Ch. Amplifier - 3Ch Mode

It is possible to run the 2-Ch. amps in “3-Channel” mode by running a pair of
speakers for the mids and highs on left and right channels, and at the same time
run a woofer bridged between the L+ and R- terminals as shown. However, since
each channel will see 1/2 the impedance of the woofer you must use a woofer of
no less than 4Ω. The amplifier sees impedance by frequency, so you can have two
2Ω loads but you must use a passive crossover on each speaker in the 3-Ch. mode.
With the crossovers in the line, the amplifier will always see a minimum load of 2Ω
on each channel at all freguencies. Main speakers can be 2Ω~4Ω. Woofer can be
4Ω~8Ω but cannot be less than 4Ω

. A 3-Way hookup requires a coil on the woofer

and capacitors on the highs to act as a crossover and maintain correct impedance.
Consult the speaker manufacturer for correct cap and coil values.

2-Ch. Amplifer - Stereo Mode

A simple 2 channels hookup for a right and left stereo pair.

2-Ch. Amplifier - Single Channel Mode

This method is used most often to drive a mono woofer but can also be used to run
separate amplifiers for the right and left channel. The bridged speaker must be of 4Ω
minimun impedance.
