==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
* 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
* 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
* AMP OFF:  Short – speaker in shutdown mode, Open – Speaker in operation mode

FAQ

Q1. How to use the pin header marked “PWR ON” , “SPK MUTE” and “AMP OFF”?.

A:

  • 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
