D122 integrated stereo class-D amplifier
 D-123 stereo class-D amplifier

We offer an alternative being a complete set with the possibility to connect a passive subwoofer. The amplifying part then holds two D-122 modules, where one of them is functioning as a "bridge" amplifier. This is combined with a special control unit having an active filter for the bass amplification. This control unit is supplied with special (discrete!) shunt regulators.

The picture (at left) shows the control amp on the left with its separate bass preamp. The bass level can be fixed with the blue preset potentiometer. The volume is controlled with a reliable Alps potentiometer.
