APPENDIX A. Bridge mode operation
To operate in bridge mode, follow these steps:
1. Switch off the amplifier.
2. Turn volume control potentiometers on the front panel to minimum position (fully counter-clockwise).
3. Connect input signal to channel A.
4. Set mode switch to “BRIDGE”.
5. Connect speakers as follows:
If the selected output voltage is 100 V, the two speaker cables must be connected to the 100 V
terminal outputs.
6. A jumper must be connected between 0 volt terminals.
7. Turn volume control potentiometers on the front panel to maximum position (fully clockwise).
8. Control volume levels from the mixer or pre-amp only.
NOTE 1: Always use Class II cables.
NOTE 2: Do not connect low impedance loads to a 70 V/100 V line amplifier.
The following are several examples of bridge mode operation with distributed lines:
The first one is an example for a amplifier, which delivers 300 W in bridge mode at 100 V.
The load is 10 x , and the power selectors are at 100 V/30 W.
