Amplifier Bridging Configuration

 

1.

Set the Bridge DIP switch (13 and 14) on the rear of the unit to the ON position (1+2 or

 

 

3+4).

 

2.

Restart the amplifier, as the value of the DIP switches is only read during powering up.

 

3.

Wiring the outputs; The two channels being bridged together should have the commons

 

 

(0V) connected together, and then either the 4/8/70V/100V taps off the two channels are

 

 

then used for the + ve and the – ve to the speaker cable.

 

 

 

Warning!

! Bridging the 70V and 100V lines, the voltage will be 140V and 200V respectively.

Caution!

!Be sure that the higher voltage does not create a problem for the speakers used:

If any problem exists, this may be solved with the use of a 2:1 step down transformer
