If there is a non-Bose B1/B2 cable, OR if the B1/B2 cable has a defective, loose connection, audio can intermittently mute. It may happen with loud music because the speaker will be vibrating and shake the loose connection. This will sound like a clean muting of all audio for a second or so. There will be no visual indication.

This would only happen on one {{Model II}} at a time. If two dropped out, this is not the issue.

Very low, out-of spec, AC power (less than ~105 VAC on a 120V system, or less than around ~215 V on a 230 V system. The manual states 110 and 220 for good measure) coupled with high signal level. This can be caused by a low power source, or one where the outlets are a very long distance from the electrical panel, extra equipment on the same electrical branch, power sags or dropouts, long or multiple extension cords, or small gauge extension cords.

In this case, loud music increases the current draw, and the voltage drop over the extension cord will lower the voltage enough to cause a reset of the {{T1}}, or the {{Model II}} Power Stand.

If the {{T1}} resets, the LEDs (input trim level, mute LEDs) will turn off. The LCD display will remain blue, but be blank until the unit restarts.

The {{Model II}} Power Stand can reset but it does not show on the indicators.

In either case the answer is to ensure the power supply is solid, and dedicated to the audio equipment, and to have as short cords as possible with large wires.

Also be aware that separate wall outlets may still be on the same breaker.
