Simple idea in concept: a 12V trigger high/low button that keeps the trigger in the high state regardless of playback through the Wiim. This could be used for room correction calibration, or using the Wiim to turn on downstream gear for use with other source components.
Ideally the high state would still have a timer, but a fairly long one - 4 hours sounds like a sweet spot to me - before reverting to low state.
