Features, Applications
The Device incorporates the SRS (Sound Retrieval System) under licence from SRS Labs, Inc.

1 STEREO INPUT ATTENUATION CONTROL IN 0.5dB STEP MUTE FUNCTION MONO MODE (SRS 3D MONO) STEREO MODE (SRS 3D STEREO) SPACE AND CENTER ATTENUATORS ARE AVAILABLE ALL FUNCTION ARE PROGRAMMABLE VIA SERIAL BUS (I2C BUS)

nents and it is not affected by internal process spreads. The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers according to the SRS labs specification. Control of all the functions is accomplished by serial bus. Thanks to the used BIPOLAR/CMOS/ DMOS technology, Low Distortion, Low Noise and DC stepping are obtained.

DESCRIPTION The is a SRS (Sound Retrieval System) audio matrix. It reproduces SRS sound processing stereo and mono sources both. The SRS sound is guaranteed by external compoPIN CONNECTION (Top view)
