1. High Impedance Input (Low Level Input)

This unit is provided with RCA input jacks for high impedance. Couple the RCA input with the car
stereo or equalizer outputs using RCA type connec tor cables.

2. Input Gain Control.

These are NOT Your amplifiers volume controls. They are a sophisticated device which is to be
utilized when matching the input signal of your head unit or equalizer to their amplifier.

Some people automatically set the gain to maximum because they want their music loud, by doing
this they are also increasing the chance of burning out their amplifiers input stage should the
source signal already be of a high value. Please follow the precise instructions found later in this
manual to help match the signals correctly.

Your system can also become extremely sensitive to noise conditions when you have a high signal
level coming into the amplifier and you also have a high gain set on the amplifier. So avoid lots of
problems and match your system correctly!

3. Bridging Capability.

The PLMRA200 can be bridged to a high power one channel unit. Make sure that you have a
speaker or series of speakers on the bridged channel capable of handling at least 100 Watts or
RMS power.

4. Low Impedance Input (High Level Input)

This unit is provided with terminal inputs for low impedance. Couple the terminals with a standard
car stereo output system wither common ground to floating ground type originally output to speak­ers. The speaker wires of the car stereo should be connected to “L-” and “R-” terminals respec­tively. If the car stereo comes out with three wires only, connect the “COMMON” wire to both “L”
and “R” input of the amplifier.

5. Power Supply Terminal

Connect the +12V DC power supply into the terminal by lugs and screws accessible at the panel of
this amplifier.

BATT +12V

Connect +12V DC power supply wire into the terminal from the terminal of the battery.

GROUND
Ground terminal connect the ground wire to the chassis of the automobile

REMOTE
Remote terminal connects the control wire which provides remote turn-on and off of the amplifier
by the radio/cassette play or equalizer

6. Power On LED.

When the PLMRA200 is properly grounded and has proper power and is receiving its remote power
signal the green LED will light up indicating power conditions are correct.

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
expectanc y 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 cir­cuitry 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.
