cations in Hi-Fi systems.  
TWO SURROND MODES AVAILABLE  
Selectable input gain is provided. Control of all the  
- MUSIC  
functions is accomplished by serial bus.  
The AC signal setting is obtained by resistor net-  
works and switches combined with operational ampli-  
fiers.  
PSEUDO STEREO  
ALL FUNCTION ARE PROGRAMMABLE VIA  
SERIAL BUS  
Thanks to the used BIPOLAR/CMOS Technology,  
Low Distortion, Low Noise and DC stepping are ob-  
tained.
