Introduction
Thank you for choosing the PSB Alpha P5 Bookshelf Speakers. These speakers are designed to deliver pristine sound for both home theater and stereo setups. This manual provides essential information for setting up, operating, maintaining, and troubleshooting your speakers to ensure optimal performance and longevity.
Setup
Unpacking
Carefully remove the speakers from their packaging. Inspect them for any signs of damage during transit. Retain the packaging for future transport or storage.
Speaker Placement
The Alpha P5 speakers are versatile and can be placed on stands, shelves, desks, or tables. For optimal sound quality, consider the following:
- Distance from Walls: Placing speakers too close to walls can overemphasize bass. Experiment with distances to find the best balance for your room.
- Stereo Imaging: Position the speakers equidistant from your primary listening position and angle them slightly inward (toe-in) towards the listener for a focused soundstage.
- Height: Ideally, the tweeters should be at ear level when you are in your primary listening position.

Connecting to an Amplifier/Receiver
Ensure your amplifier or receiver is turned off before making any connections.
- Use high-quality speaker wire for the best audio performance.
- Connect the positive (+) terminal (red) on the back of each Alpha P5 speaker to the positive (+) terminal (red) on your amplifier/receiver.
- Connect the negative (-) terminal (black) on the back of each Alpha P5 speaker to the negative (-) terminal (black) on your amplifier/receiver.
- Ensure all connections are secure to prevent short circuits or signal loss.

Operating Your Speakers
Basic Audio Playback
Once connected, turn on your amplifier/receiver and select the appropriate input source. Start playback at a low volume and gradually increase it to your desired listening level. The Alpha P5 speakers are designed for a pure and natural soundstage.
Enhancing Your Audio Experience
- For deeper bass response, consider incorporating a dedicated subwoofer into your system.
- The Alpha P5 can be integrated with other PSB Alpha models to create a more immersive home theater setup.

Maintenance and Care
To keep your PSB Alpha P5 speakers in optimal condition:
- Regularly dust the cabinets with a soft, dry cloth. Avoid abrasive cleaners or solvents.
- If the grilles become dusty, gently remove them and use a soft brush or vacuum with a brush attachment to clean them.
- Avoid exposing the speakers to direct sunlight, extreme temperatures, or high humidity.
- Do not place heavy objects on top of the speakers.
Troubleshooting
If you experience issues with your speakers, refer to the following common solutions:
- No Sound:
- Check all speaker wire connections at both the speaker and amplifier/receiver ends. Ensure they are secure and correctly matched (positive to positive, negative to negative).
- Verify that your amplifier/receiver is powered on and the correct input source is selected.
- Ensure the volume is not set to minimum or muted.
- Distorted Sound:
- Reduce the volume on your amplifier/receiver. If distortion disappears, the amplifier may be overdriven.
- Check speaker wire connections for any loose strands that might be touching, causing a short circuit.
- Ensure the speakers are not placed too close to walls or corners, which can cause bass resonance and distortion.
- Uneven Sound (one speaker louder/softer):
- Check the balance control on your amplifier/receiver.
- Verify speaker wire connections for both speakers.
If the issue persists, consult your amplifier/receiver's manual or contact PSB customer support.
