Troubleshooting

No Power

  • Make sure the power cord is connected to both the AC mains connector and an AC wall outlet.
  • Try to change for another power cord.
  • Check the AC mains voltage indication on the back of the unit and see if it corresponds to your local power voltage.

No Sound or Low Output

  • Examine all cables to ensure a solid connection between the POLARIS and associated components.
  • If you are using the USB port, make sure the playback software’s volume is set to an audible level and not muted.
  • Make sure all associated components are powered on.
  • Make sure the associated components connected to the selected input has an audible output signal.
  • Try rebooting the POLARIS (power off the POLARIS, then power on again).

Distorted or Partial Sound

  • Check the output cables between the POLARIS and the preamplifiers / power amplifiers / active loudspeakers, make sure all are well connected.
  • Make sure that all speaker connections are tight and that no stray strands of wire shorting exist within the speaker terminals.
  • Try rebooting the POLARIS (power off the POLARIS, then power on again).

Noise / Hum

  • Check the output cables between the POLARIS and associated components, make sure all connections are well done.
  • Make sure the output cables between the POLARIS and the power amplifiers are not settled near any AC cables, power transformers, or other EMI inducing devices.
  • It may be helpful to plug all associated components into the same AC circuit in order to share a common ground.
