OPERATION MODES

Active Mode is indicated by a Blue LED, the amplifier is connected to power and ready to pass signal.

Mute mode puts the amp into a “light sleep” and occurs when the Standby option has been selected and no signal has been
detected for 10mins, if the amplifier detects signal it will wake within 1ms. When no signal has been detected for 25 mins full sleep
mode will activate.

The Orange LED’s indicates the amplifier is in Standby, a power saving mode. This mode can be enabled by toggling the under
panel A-STBY switch from Off to On. In this mode if no signal is detected for 25 mins the amplifier will “sleep” and wake within
660ms of detection of signal.
