PLMRA220 – 2-Channel Amplifier Control Functions

Crossover Mode Selector: When used with normal full-range systems, set this switch to “FULL.” If you wish to use the internal crossover to power a driver of a specific frequency range, use the “LOWPASS” or “HIGHPASS” settings.
Input Level Control: Use this control to match the output of your head unit to the amplifier. Start with your head unit set at about the 2 o’clock position, increase the amp level control until distortion begins, and then reduce slightly.
Low Pass Frequency Control: When the crossover selector switch is in “LOW PASS” mode, this control sets the upper-frequency limit for the audio program sent to the speakers.
High Pass Frequency Control: When the crossover selector switch is in “HIGHPASS” mode, this control sets the lower frequency limit for the audio program sent to the speakers.
Bass Boost Level Control: This control permits adjustment of the bass level up to an increase of approximately 18 dB.
Low-Level Inputs: This amp features gold-plated RCA input jacks for high-impedance input. Use these with car stereo outputs that utilize RCA-type connector cables.
High-Level Inputs : If your car stereo lacks RCA-type output jacks, you may connect the speaker output leads to these input connectors.
Power LED: This indicator lights up when power is applied.
Protection LED: This indicator lights up when the built-in protection circuitry is activated.
Power Fuse: The fuse protects the amplifier and your car’s electrical system from short circuits.
Power Terminals: Use these connectors to deliver power, ground, and remote turn-on control to the amplifier. Speaker Connections: These terminals are 14K gold-plated to guarantee high conductivity and minimize signal loss.

Mounting and Installation

Mounting
Your new Pyle Marine Series amplifier comes with all the necessary mounting hardware. When choosing a location in your vehicle, keep in mind that the amplifier is a high-power electronic device that generates significant heat.
Key Considerations for Mounting

Choose a location with low vibration, adequate ventilation, minimal dust, and no moisture.
Ensure there is sufficient airfow around the cooling ns.

Steps for Mounting

Position the amplifier: Place the amplifier where you want to install it.
Mark Screw Holes: Use a scribe or one of the mounting screws to mark the mounting surface through the screw holes. If the surface is carpeted, measure the hole centers and mark them with a felt-tip pen.
Check for Obstructions: Before drilling, check for any wires, lines, or other components behind the mounting surface.
Drill Pilot Holes: Drill the pilot holes in the marked locations.
Secure the Amplifier: Insert and tighten the mounting screws securely.

Wiring Tips
When connecting your amplifier, follow these guidelines:

Power and Ground Connections: Use at least 8 gauge wire.
Direct Connection: Wire the amplifier directly to the car battery.
Grounding: Use the shortest possible wire to connect to a good chassis ground point.
Remote Connection: Wire the Remote connection to the auto start lead of your head unit, equalizer, or power antenna.

About Power Fuses
Pyle Marine Series amplifers have a built-in fuse system to protect both the amplifier and your vehicle’s electrical system from faults. Fuse Replacement: If you need to replace a fuse, use one with the same type and rating. Using a different type or rating could cause damage or a free.

Precautions

Mounting: Do not operate the amplifier when it is unmounted. Securely attach all audio system components within the vehicle to prevent damage, especially in case of an accident.

Wiring Protection: Ensure the wire connections are protected, not pinched, and not likely to be damaged by nearby objects.

Battery Disconnection: Before making or breaking power connections, disconnect the vehicle battery. Make sure your head unit or other equipment is turned off while connecting the input jacks and speaker terminals.

Fuse Replacement: If you need to replace the power fuse, only use a fuse identical to the one supplied with the amplifier. Using a different type of rating may result in damage that isn’t covered under the manufacturer’s warranty.

Protection Circuitry
The built-in protection circuitry in the Marine amplifers will disable the amplifier if it detects:

Input overload
Speaker short circuit
Extreme temperature conditions

Protection LED:
When the protection circuit is activated, the Protection LED will illuminate.

Steps to Follow:

Thermal Overload: If the shutdown is due to thermal overload, allow the amplifier to cool down before restarting.
Input Overload/Speaker Short Circuit: If the shutdown is due to input overload or a speaker short circuit, correct the issue before restarting.
Restarting: Turn the remote power OFF and then ON again to restart the amplifier.

Troubleshooting

No Output:

Ensure all terminal strip connections are secure and tight.
Check both in-line and built-in fuses. Both the +12V and the Remote terminals must have +12V referenced to the chassis ground.
Verify that the audio signal source (car radio, equalizer, etc.) is connected and supplying an output signal.
To check if the amp is supplying a signal, unplug the cables from the signal source (but leave them plugged into the amp). Briefly tap the center pin of each disconnected RCA plug with your anger. This should produce a noise (feedback) in your speakers.

Only One Channel Works:

Ensure all terminal strip connections are secure and tight.
Check the Balance control on the head unit (or other source) to ensure it is set to the midpoint.
If using the Low-Level RCA input, reverse the input plugs at the amplifier (i.e., switch the L with the R). If the silent channel switches to the other side, the problem is either in the head unit/other source or the connecting cables. Weak Output: Adjust the Input Level Control(s) to better match the input signal.

Noise in the Audio:

Whine (Engine Speed-Dependent): Ensure that the amplifier and any other signal sources (head unit, etc.) are properly grounded.
Clicking/Popping (Engine Speed-Dependent): This usually indicates that the vehicle has resistor spark plugs and wires, or the ignition needs servicing.
Check Wiring: Ensure that the speaker and input wires are not near wires that interconnect lights and other accessories.
If these steps don’t resolve the noise interference, consult a professional mobile audio installer.
