5.4 GPIO Setup and Connection
PowerZone Connect ampliers 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 5g. The connection of GPIO
based remote volume control and standby/mute are
illustrated in Diagram 5h and Diagram 5i respectively.
Note: The GPIO connector must not be used for
any unintended purpose. Amplier damage may
result from incorrect use of GPIO.
Note: Shielded cable must be used when
connecting standby switches and potentiometers
and via GPIO.
Note: GPIO Pin 8 has an output impedance of 1kΩ.
Connected devices must be able to sink 3.3mA.
