Control of all the functions is accomplished by serial bus. The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers. Thanks to the used BIPOLAR/CMOS Technology, Low Distortion, Low Noise and DC stepping are obtained. solete roduc LP1 b P HP1 O te HP2. le REAROUT REARIN so VAR_L b BASSO_L O VAR_R LP PS1 PS2 PS3 PS4 VS CREF R_IN4 R_IN3 R_IN2 R_IN1 44 43 42 41 40 39 38 37 36 35 34 1 33 2 32 3 31 4 30 5 29 6 28 7 27 8 26 MONITOR_R MONITOR_L L_IN1 L_IN2 L_IN3 L_IN4 AUXOUT_L AUX...
