its correct use. Keep this manual for future reference.

INTRODUCTION

The PLMRA402 has been designed using the latest electronic technology available.

The PLMRA402 is with engineered features allowing you to produce high quality

stereo repro duction in mobile applications. This innovative system has been

designed a 12 volts DC negative ground power supply.

Easy installation with mounting hardware is provided. The PLMRA402 has two

input levels. The high or low impedance input can be connected to units which

incorporate BTL circuity or common-ground types.

FUNCTIONS

1. POWER ON LED: Lights up when the remote on system is energized.

2. INPUT GAIN CONTROL: Adjust high impedance input gain from 1 V to 300mV

for best matching with PREAMP output for your car stereo.

3. LOW IMPEDANCE INPUT (HIGH LEVEL INPUT): This unit is provided with two

terminal inputs (Front & Rear) for LOW impedance. If your car stereo has four

speaker outputs (LF, RF, LR, RR). Wire input as per FIG. 3 & FIG 3A.

If your car stereo has two speaker outputs, please wire as per FIG 4 & FIG 4A.

4. HIGH IMPEDANCE INPUT (LOW LEVEL INPUT): This unit is provided with gold

plated RCA input jacks for high impedance. Couple the RCA input with the car

stereo output using RCA type connector cables. If your stereo has only left and

right 2 channels outputs. You must use a Y-adaptor for connection (FIG 2).

5. POWER FUSE: Power fuse protects both this amplier and the automobile

electrical system from wrong electrical conditions.

6. POWER SUPPLY TERMINAL: Connct the +12V DC power supply wire into this

terminal. By lugs and screws accessible at the panel of this amplier (Fig. 5).

A. BATT + : Connect +12V DC power supply wire into this terminal from the (+)

terminal of the battery.

B. GROUND: Ground terminal connects the ground wire from the chassis of the

automobile.

C. REMOTE: Remote terminal connects the control wire which provides remote

turn-on and o of the amplier by the RADIO/CASSETTE players power

antenna wire.

7. SPEAKERS TERMINALS: Speakers can be easily connected to signal barrier strip.

You may use 4 to 8 ohms speakers. Before connecting, please check speaker

connection diagrams.

NOTE: High and low impedance input cannot be used at same time.

B. SPEAKER CONNECTION

Connect the speaker output terminals to the corresponding speakers. (Figure 5)

The speakers must be high quality and capable of handling high power.

Separated return paths and strong wires are required. (Fig. 5)

NOTE:

This amplier has built-in short circuit protection. If you mistakingly connect any

speaker wires to ground, or positive power (+) and (-) wires short together, the

protection circuit will operate automatically and cut-o output. In case of this,

you must switch OFF the whole system immediately double check speaker wire

connections and isolation before switching on the amplier again.

C. POWER CONNECTION

1. Connect the B+12V pole of power supply directly to the battery (+) position

terminal.

2. Connect the GND pole of power supply directly to the (-) negative ground

battery terminal or car chassis.

3. To make a good grounding and prevent motor boating noise problem connect

another 12 gauge minimum wire from the (-) negative battery terminal to

chassis of stereo unit.

4. Connect the 'Remote' pole to external switch for positive 12V ON/OFF.

This may be connected to the receiver power antenna lead.

INSTALLATION

This amplier comes complete with mounting hardware, if the unit is used in the

line level (high impedance) mode, it is recommended to use gold plated RCA

connection cables with the length as short as possible and mount the unit as

close as possible to the receiver. This will lower the chance of stray magnetic pick

up that may cause noise in the system.

1. Choose a suitable location.

2. Check the clearance behind and above the mounting area.

3. Wire unit according to the proper wiring digram.

4. Using the hardware provided, attach the unit to mounting surface.

MAINTENANCE

Your PYLE power Amplier is an example of superior design and craftsmanship.

The lowing suggestions will help you care for your amplier so you can enjoy it

for years.

Keep the amplier dry. If it gets wet, wipe it dry immediately.

Liquids can contain minerals that corrode electronic circuits.

Use and stre the amplier only in normal temperature environments.

Temperature extremes can shorten the lile of electronic devices and

distort or melt plastic parts.

Handle the amplier gently and carefully. Dropping it can damage circuit

boards and cases and can cause theamplier to work improperly.

Keep the amplier away from dust and dirt which can cause premature

wear of parts.

Wipe the amplier with a damp cloth occasionally to keep it looking new.

Do not use harsh chemicals, cleaning solvents, or strong deter gents to

clean the amplier.

TESTING

1. After all the connections have been made, turn ON your stereo and listen for the

amplier to turn ON. If there are any unusual noises from the speakers then turn

the system o and recheck all the wiring.

2. After you have connected your radio or equalizer to the amplier, you may

adjust the gain control to match the output level of your radio.

A. Set the volume control on your radio to 2/3 position.

B. Adjust the gain control for an average listening level.

C. Turn the radio volume all the way down and listen for background noise.

D. Start your vehicle and listen for electrical noise.

E. Making ne adjustments to the sensitivity can reduce background noise and

some engine noise.

F. CAUTION: Never turn the sensitivity up any farther than you need to get clear

sound at 2/3 volume.

G. This adjustment only needs to be made once.
