STANDBY
The standby functionality is activated using the supplied 6-way Phoenix connector which must be wired to close the contact on the
standby pin on the rear of the ISP unit by connecting it to ground. See connection diagram listed below for a simple connection.
When in standby, the amplifier has entered a power saving mode where no audio will be present at the output. When the standby
connection is removed the amplifier will restart the power amplifier and exit standby.
The amplifier ships with energy saving mode enabled and will enter auto standby if it detects a period of inactivity less than (-40dBV)
for 30 minutes. The amplifier will exit standby mode when the signal level returns above -40dBV. The auto standby function can be
disabled and the timeout period modified in the user interface.
