The second thing we did was redesign the {{L1}} software so that it could "filter out" the effects of momentary crosstalk and not cause the problem. That way future L1's would not have the issue.

The user manual states 5 amps or greater, so six amps is a good approximation. For that reason, we recommend only up to two L1 MII’s on a single 15A circuit breaker in the US.

This would only happen on one L1 MII at a time. If two dropped out, this is not the issue.

2. 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 L1 MII base.

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

The L1 MII base can reset but it does not show on the indicators.
