The following troubleshooting tips can help diagnose and correct most concerns with the HDP6 or P4. We have attempted to make this list as comprehensive as possible, so some of these may not apply to your issue, but please go through each tip.
- Verify that the power controls for your amp, preamp, and/or AV receiver are powered on and working.
- Check that the volume level of your audio source components or devices are turned up.
- Check the speaker wire connections from your amp to the speakers by removing the speaker wire from each speaker and then reconnecting. Also check the speaker wire polarity by verifying that the wires are going to the same terminals on both speakers.
- Check that the cables from your audio source(s) to the amplifier are properly connected. Confirm this by unplugging the audio cables and then reconnecting.
- Try using different audio input sources and/or devices to see if the problem follows.
- Try swapping inputs to the left and right speaker to see if the issue remains in the same channel or follows the speaker.
- If you are using a computer with your setup, make sure the volume is up on your media players, internet radio, master control, device volume, etc. and that the balance control is centered.
- If you are using a wireless adapter, preamp, or external DAC, remove these (temporarily) and connect the audio source directly to the amp/speakers.
- If your input source has its own EQ (equalizer), please make sure the low end is at a moderate level as having too much bass can cause distortion.
- Move your amp and HDP6/P4 speakers to a different location to see if something is causing interference in the current setup. Something as simple as a wireless internet router, cordless or mobile phone, or halogen lamp nearby can cause interference.
