Set the energy safe option (APD)
The APD (Auto Power Down) automatically places the amplifier into a low power standby
mode after a period of inactivity when signal, such as a music source, is not present for an
extended period.
The threshold level of the APD is -45 dBu* and will automatically activate standby if the
signal is constantly below this level for 25 min across all inputs.
The amplifier is woken from APD to full activity by:

APD is configured as either ON or OFF using the APD DIP switch at the rear of the device.
