5. Setup

5.1 Speaker Placement

Place the speakers on a stable, flat surface. For optimal stereo imaging, position the speakers equidistant from your listening position, forming an equilateral triangle. Ensure there is sufficient space behind the speakers for ventilation and cable connections.

5.2 Connecting the Speakers

1. Connect the supplied speaker cable (1.5m) from the L-OUT terminal on the active speaker to the L-IN terminal on the passive speaker. Ensure a secure connection.

5.3 Connecting Audio Sources

You can connect audio sources using either the RCA inputs or the stereo mini input:

• RCA Input (INPUT A): Use the supplied stereo mini to RCA x 2 cable to connect devices with RCA outputs (e.g., CD players, audio interfaces) to the INPUT A jacks.
• Stereo Mini Input (INPUT B): Use a 3.5mm stereo mini cable (not supplied, unless the stereo mini to RCA cable is used with an adapter) to connect devices with a stereo mini output (e.g., smartphones, computers) to the INPUT B jack.

5.4 Connecting Power

1. Connect the supplied AC adapter to the DC IN jack on the active speaker.
2. Plug the AC adapter into a suitable wall outlet. The power indicator LED on the front of the active speaker will illuminate blue.

6. Operating Instructions

6.1 Power On/Off

The speakers power on automatically when the AC adapter is connected to a power source. To turn off the speakers, disconnect the AC adapter from the wall outlet.

6.2 Adjusting Volume

Rotate the VOLUME knob on the rear panel of the active speaker to adjust the sound level. Turn clockwise to increase volume and counter-clockwise to decrease it. Start with a low volume and gradually increase it to a comfortable listening level.

6.3 Input Selection

The PM0.3H(B) supports two audio inputs (RCA and Stereo Mini). If both inputs are connected, the speaker system will mix the audio signals. To listen to a single source, ensure only that source is connected or powered on.

7. Maintenance

7.1 Cleaning

• Before cleaning, disconnect the power adapter from the wall outlet.
• Wipe the speaker cabinets with a soft, dry cloth.
• Do not use abrasive cleaners, waxes, or solvents as they may damage the finish.

7.2 Storage

When not in use for extended periods, store the speakers in a cool, dry place away from direct sunlight and extreme temperatures. It is recommended to keep the original packaging for safe storage and transport.

8. Troubleshooting

If you encounter any issues with your FOSTEX PM0.3H(B) speakers, refer to the following common problems and solutions:

8.1 No Sound

• Check Power: Ensure the AC adapter is securely connected to both the speaker and a working wall outlet. Verify the power indicator LED is blue.
• Check Volume: Confirm the VOLUME knob on the active speaker is not set to minimum (OFF) and the volume on your audio source is turned up.
• Check Connections: Ensure all audio cables (RCA, stereo mini, and the speaker cable between active and passive units) are securely connected.
• Test Audio Source: Try connecting a different audio source to rule out issues with your primary device.

8.2 Distorted Sound

• Adjust Volume Levels: Reduce the volume on both the speakers and your audio source. Overdriving either can cause distortion.
• Check Cable Quality: Ensure audio cables are not damaged or poorly shielded, which can introduce noise.
• Source Quality: Low-quality audio files or streaming can result in distorted sound.

8.3 Only One Speaker Producing Sound

• Speaker Cable: Verify the speaker cable connecting the active and passive units is properly and securely connected at both ends.
• Audio Source Balance: Check the balance settings on your audio source.
• Input Connection: Ensure the stereo mini or RCA cables are fully inserted and not loose.
