Bazooka RBCM-RS

The RBCM-RS remote control module is compatible with RS series powered Bazooka tubes whose model numbers end with the letters "HP," as well as BT 200 Series models BTA1020, BTA6200, and BTA8200.
The included cable (16 feet, 4 inches long) has a 6-pin connector on each end — one end plugs into the module, while the other end plugs into the 6-pin plug found on the compatible tubes.
The module has one knob which controls the amp's gain setting, and a second knob which selects the crossover point (50-120 Hz).

This remote control is only compatible with:
RS Series powered Bazooka tubes whose model numbers end with the letters "hp" such as: RS6A-hp, RS8A-hp, and RS10A-hp
BT Series A200 powered Bazooka tubes (with 200-watt max amplifier) such as: BTA6200, BTA8200, and BTA10200
Marine BT series (with 200-watt max amplifier): MBTA8200 and MBTA10200
Also works with older Marine HP high powered amplified tubes: SM8A-hp and SM10A-hp
