The is a bass boost IC developed for use in minicomponent stereo systems, TV sets, and radio/cassette player products. The cutoff frequency is determined by external capacitors, and the boost gain, addition level, and boost on/off state can be controlled by a microcontroller.
Left and right channel boost addition on/off Bass output pin for use in 3D systems Boost on/off LED on/off 8-bit serial microprocessor interfaceFeatures
The bass boost gain is variable over a maximum range in 5-dB steps, and the addition level into the left and right channels can be controlled over 35 dB range in 3-dB and 5-dB steps. This allows an optimal boost for the source and volume to be acquired using microprocessor control. Includes two AGC circuits on chip: a level limiter (2 V rms) for the maximum input in low-frequency boost mode and a non-clipping limiter (i.e. clip prevention) circuit. Can be switched between 2D and 3D systems.
