Protect Indicator Led - Art SLA-4 User Manual

PROTECT INDICATOR LED

The LED will glow when the channels associated with it go into protect
mode. In protect mode, the output signal to the speakers will be muted
(channel specific). If there is a fault condition at the speaker outputs
(due to a severe load or short) the LED will light until the fault is
removed.
Channels One and Two share a Protect LED, as do channels Three
and Four on the SLA-4.
The protect lights will also light during power up and down, to indicate
that the signal is muted.
