N22 Troubleshooting Tips

The following troubleshooting tips can help diagnose and correct most concerns with the N22. We have attempted to make this list as comprehensive as possible. So, even though some of these may not apply to your issue, please still go through each one.

If the power indicator LED on the N22's external power supply unit is not on, then try these tips:

  1. Connect the AC power cord to the power supply unit and to a working AC power outlet.
  2. Plug the cable at the other end of the power supply into the rear of the N22.

If the power supply light is on but you are experiencing an audio-related issue, try these tips:

  1. Verify that the volume/power control on the front panel is not all the way down or off.
  2. Ensure that your audio source is on and that the volume level is not too low.
  3. Check speaker wire connections from the 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 same terminals on both speakers.
  4. Unplug and reconnect the cable(s) from your audio source(s) to the amplifier.
  5. Try decreasing the volume of the input audio source and increase the volume of the N22 amp.
  6. Try using different audio input sources and/or devices to see if the problem follows.
  7. Listen with headphones if possible to see if the issue is present there as well.
  8. Try swapping your left and right speaker to see if the issue remains in the same channel or if it follows the speaker.
  9. When using the N22 with a computer, make sure the volume is up on your media player, internet radio, master control, device volume, etc. and that the balance control is centered.
  10. If you are using a wireless adapter, preamp, or an external DAC with your N22, remove these (temporarily) and connect the audio source directly to the speakers.
  11. If your input source has its own EQ (equalizer), please make sure the low end is at a moderate level. Too much bass in your signal can cause some unwanted distortion.
  12. Move your N22 and 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.
