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.
