DUAL LINK AMP TO EXTERNAL BRIDGING
The PowerBass XMA Class D Mono amplifiers are equipped with a special Dual Link circuitry that allows you
to link (strap) two like amplifiers together and double the output power at a minimum 2-ohm load. External
Bridging two amplifiers (must be the same models) can be done via the
MASTER
and
SLAVE
switches,
BRIDGGED CONNECTION cable and proper speaker wiring. Doing so will allow only the preamp controls
(Gain, X-Over, Subsonic, Bass EQ, etc) on the
MASTER
amplifier to control both amplifiers. The preamp
controls on the
SLAVE
amplifier will become inactive. This holds true for the Remote Level Control as well, it
will only function with the
MASTER
amplifier.
Follow the preceding diagrams carefully when using the Dual Link function. Make sure the
MASTER
and
SLAVE
switches are properly selected on each amplifier as shown in Fig 16. Failure to do so will result in
damage to the system.
NOTE: This switch should always be set to the MASTER position for standard operation of one
amplifier. Changing the position to SLAVE will result in no output
