| 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
