5
Temp LED
The Temp LED lights when a channel’s output relay is open, discon-
necting the speaker(s) because of an overheating condition. Once the
channel temperature has returned to a safe level,the LED will turn off
and the speaker(s) will be reconnected.
6
DC LED
The DC LED lights when the channel’s output relay is open, discon-
necting the speaker(s) when the amplifier senses a DC voltage or sub-
sonic signal at its output.
7
Active LED
The Active LED indicates that a channel’s output relay is closed and
operational. It lights under normal operation and remains on, even
when the channel is in ACL gain reduction. These protection features
leave the output relay closed. If the Active LED goes off, there will be
no signal at the output connector(s).
8
Airflow Outlet Grille
Pro 200 Series amplifiers are cooled by dual, variable-speed, rear-
mounted fans. Cool air flows over the heat sink and exhausts through
the front grille. Make sure this outlet remains clear to allow unre-
stricted airflow.
9
AC Power Switch/Circuit Breaker
Pro 200 Series amplifiers have a combination AC switch/circuit break-
er on the front panel. If the switch shuts off during normal use, push
it back to the ON position once. If it will not stay on, the amplifier
needs servicing.
