C2 should be polyester film capacitors with no secondary resonance (non-inductive), to assure stable operation. Notes: 1. Standby Power is turned on when a signal of 3.5 V or 0.05 m A is impressed at pin 2. When pin 2 is open or connected to GND, standby is turned on (output off). 2. Muting Muting is turned off (output on) when a signal of 3.5 V or 0.2 m A is impressed at pin 10. When pin 10 is open or connected to GND, muting is turned on (output off). 3. TAB (header of IC) connected to GND.
