Using the Aux Port
The Aux port can be used for basic monitoring of the amplifier and for remote standby (sleep). The port is a 3-pin block connector with pin 2 used as ground.

Sleep
The amplifier can be put to sleep by connecting pins 1 and 2 together on the Aux port. When applying this connection, the amplifier will shut down and remain in standby
until the connection between pins 1 and 2 is opened. When the connection between pins 1 and 2 is opened, the amplifier will revert to its last configuration and begin to
output audio within ~20 seconds. Network communication will be re-established once the network interface card boots. While the amplifier is in standby, the front-panel
Power
button is disabled and, if pressed, the blue
Power
indicator will blink twice to indicate the device is in standby.

Amp Status
Amp Status can be used for basic monitoring of the amplifier. Monitoring of the amplifier can determine if it is operating within optimal parameters or if it has been shut off
or is in fault.
There will be either a +5VDC potential or a 2Hz square wave (heart beat) between pins 2 and 3. This option can be set from the Amplifier Information panel, which can be
accessed by clicking the
Amp Info
button on the amplifier's Configuration panel (see
).
