DESCRIPTION
The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers according to the SRS laboratories MIDDLE_LO BASS_RI MIDDLE_RI TREBLE_L BASS_RO MIDDLE_RO MIDDLE_LI TREBLE_R AGND SDA SCL LPVC D96AU483C PS1 PS2 PS3 PS4 LP specification. Control of all the functions is accomplished by serial bus. Thanks to the used BIPOLAR/CMOS Technology, Low Distortion, Low Noise and DC stepping are obtained.
