7. Protection LED
This is indicator is illuminated when built-in protection circuitry is activated.
8. Power Fuse
Power fuse protects both this amplifier and the automobile electrical system from wrong electrical
conditions.
9. Speaker Terminals.
The speaker terminals are 14K Gold Plated for high conductivity and minimum impedance loss.
The terminals are facing upwards for easy wiring in tight situations. Be sure to strip just enough
insulation off your speaker wires that will fit under the screw plate to help ensure against speaker
wire short circuits.
The PLMRA200 can support an impedance load as low as 2 ohms per channel or 4 ohms in the
bridged mode, though a 4 ohm stereo load and 8 ohms bridge load will greatly increase the life
expectancy of the amplifier.
10. Crossover Frequency Circuit
Lets you adjust the crossover frequency from 40-450 Hz for both channels.
11. Crossover On/Off Switch
Lets you set the amplifier to drive a connected subwoofer.
12. Mute Turn On Circuit
The PLMRA200 features an anti-thump delay circuit. This circuit eliminates irritating thump noises
some times experienced with cheaper amplifiers when they are turned on.
13. Short Circuit Protection.
Advanced protection circuits have been designed into all PLMRA200 amplifiers. The protection cir-
cuitry will disable the amplifier if it senses an input overload, speaker short circuit or extreme high
temperature conditions. When the protection circuit is in operation the LED indicator on the unit
will light indicating that the amplifier has gone into a self preservation mode. At this time please
check your system to see what is causing the protection circuit to fire. The amplifier can be reset
by turning the remote power off and then on again. If the system shuts down because of a thermal
overload condition, allow the amplifier to cool down before restarting. If the amplifier shutdown
because of an input overload or speaker short circuit please be sure to correct these conditions
before restarting the amplifier.
WARNING!
Do not play your music at a level which will inhibit your hearing necessary traffic safety sounds!
Long term listening at extreme high levels may cause loss of hearing.
