FAQ

1. How to use the pin header marked “PWR ON” , “SPK MUTE” and “AMP OFF”?.

• PWR ON: Short - Auto power on when power applied, Open – Using an external latching switch to control power on/off
• SPK MUTE: Short – Speaker un-muted, Open – Mute enabled and it is controlled by GPIO22 with additional software setting e.g high = speaker unmuted, Low=speaker muted
• AMP OFF: Short – speaker in shutdown mode, Open – Speaker in operation mode
