Setup and Installation
Follow these steps for proper installation of your Pyle PLMPA35 amplifier:
1. Mounting the Amplifier
Choose a suitable location for mounting the amplifier. Ensure it is a dry, well-ventilated area, away from direct heat sources or excessive vibration. The compact design allows for discreet placement. Use appropriate screws (not included) to secure the amplifier through its mounting tabs.
2. Power Connection (12V DC)
The amplifier requires a 12V DC power source. Use the provided power wiring harness.
- Red Wire (Constant Power): Connect this wire to a constant +12V DC power source (e.g., car battery positive terminal). It is recommended to use an inline fuse (not included) for protection.
- Black Wire (Ground): Connect this wire to a solid chassis ground point (e.g., car chassis). Ensure a clean, secure connection.
- Orange Wire (Remote Turn-On): Connect this wire to a switched +12V source that turns on when your audio source (e.g., car stereo) is activated. This allows the amplifier to power on and off with your main unit. Alternatively, you can connect this directly to the Red Wire for constant power, but this means the amplifier will always be on when connected to power.

The heat sink fins are visible on top, and a control knob is on the side. This image illustrates the overall design and key labeling of the unit.
3. Audio Input Connection
Connect your audio source to the amplifier using the 3.5mm auxiliary input jack. This allows you to connect devices such as smartphones, MP3 players, laptops, or other digital music players.
4. Speaker Output Connection
Connect your speakers to the amplifier using the provided speaker wiring harness. Ensure correct polarity (+ to + and - to -) for each speaker. The amplifier supports two speakers.

Operating Instructions
- Power On/Off: The amplifier will power on automatically when the remote turn-on wire receives +12V (if connected to a switched source) or when the main power is supplied (if connected for constant power). There is no separate power switch on the unit.
- Adjusting Gain Control: Use the rotary knob on the side of the amplifier to adjust the gain (volume) level. Start with a low setting and gradually increase it to your desired listening level, avoiding distortion.
- High/Low Range Filtering Switch: The switch on the unit changes between high and low range filtering. This allows you to optimize the audio output for different types of speakers or sound preferences. Experiment with both settings to find the best sound quality for your setup.
Maintenance
- Keep the amplifier clean by wiping it with a soft, dry cloth. Do not use liquid cleaners or solvents.
- Ensure adequate ventilation around the unit to prevent overheating. Periodically check that the heat sink fins are free from dust and debris.
- Regularly check all wiring connections to ensure they are secure and free from corrosion.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | No power; incorrect wiring; audio source issue; gain too low. | Check 12V DC power and ground connections. Verify remote turn-on wire. Ensure audio input cable is securely connected. Increase gain control. Check speaker connections. |
| Distorted sound | Gain set too high; faulty speakers; poor audio source quality. | Reduce gain level. Test with different speakers. Ensure audio source is providing a clean signal. |
| Amplifier gets hot | Lack of ventilation; prolonged high-volume use. | Ensure amplifier has adequate airflow. Reduce volume or allow unit to cool down. This is normal during use. |
| Unit does not turn on | No 12V DC power; remote turn-on not connected or faulty. | Check all power connections (Red, Black, Orange wires). Verify fuse if used. |
