[SML] ETC Sensor Dimmer rack running 120 circuits

[Matthew Breton]

Dimmer doubling is a possibility, but should give you 192 circuits, not 120.

Is it possible there's a second rack (perhaps disguised as an architectural or relay rack) that's driving those additional 24 circuits?  Or perhaps some lights -- front of house or in the pit -- are driven by a separate rack?

Subject: [SML] ETC Sensor Dimmer rack running 120 circuits

As you may know, I began my return to educational theatre last week at a small university in central Iowa and have run across something that I am confused about regarding the lighting system.  It appears to be an older ETC system with a single Sensor rack (96 dimmers).  However, we are somehow driving discrete 120 circuits (there are a couple that are labeled as duplicates, but not enough to account for the 24 extra circuits)

Can anyone explain how this might work?
