System Standby Function
Standby Mode is a feature that reduces power consumption after the amplifier has not been used to amplify audio
signal for a period of two hours. After entering the automatic standby mode, the amplifier displays an amber light
at power button.
Normal ON mode may be resumed by
1. speaking into a microphone that is on,
2. sending an audio signal into one of the line inputs *such as a projector or flat panel audio signal), or
3. pressing the power button once.
It may take a few seconds for the normal mode to resume after one of these actions is taken. A page signal can
also “wake” the amplifier, but to hear the full first page of a morning, be sure to wake it first with one of the methods
above since, or the initial several seconds may be missed if there are no other paging speakers provided to deliver
the page audio.
