- Page 20 AUDIO DISTRIBUTION Configuration Diagram 6O 6.5 GPIO Setup and Connection GPIO Settings Menu The AMP-4-125 and AMP-8-125 amplifiers provide a GPIO socket that enables remote control of volume, standby, mute and trigger functions. The GPIO connector pin functions are described in the GPIO Settings menu illustrated in Diagram 6O. The connection of GPIO based remote volume control and standby/mute are illustrated in Diagram 6P and Diagram 6Q respectively. Note: The GPIO connector must not be used for any unintended purpose. Amplifier damage may result from incorrect use of GPIO. Note: Shielded cable must be used when connecting standby switches and potentiometers via GPIO. Note: GPIO Pin 8 has a low output impedance and is able to supply a maximum current of 10mA. Note: GPIO Pin 1 and Pin 3 both offer ground connections: Pin 1 is connected directly to the amplifier chassis. Pin 3 is connected to the chassis via a 220 Ohm resistor. The ‘soft ground’ connection of Pin 3 is potentially useful for managing ground loops that may cause audible hum.
