6ch Electronic Volume for 5.1ch Car Theater Systems

The BD3433K high performance 6ch electronic volume processor integrates a soft switching circuit that mitigates switching shock noise during a range of conditions, including due to high amplitude input. This makes it particularly well-suited for 5.1ch car surround sound/theater systems.

Features

Soft switching circuit eliminates switching shock noise

ROHM's soft switching circuit represents a significant improvement over conventional switching circuits by gradually adjusting the amplitude of high amplitude signals, eliminating switching shock noise. In addition, unlike conventional circuits, complicated control and external parts are not required, simplifying design considerably.
