Another Solo Problem SOLVED!
« on: June 12, 2026, 08:33:58 PM »
Hello,
I was working on a 4072 G+ at another studio and noticed that a single channel does not mute the other channels (Cut) when the LF Solo switch is engaged,
nor do the Cut lights illuminate.
If a second channel is also switched to Solo, all other channels are muted and the Cut lights do light up.
Same behaviour on all Channels.

Today I recapped almost the whole Center Section (all Cards but the top four Cards).
The Bottom Logic Card with the Ribbon Cables attached looks fine.

Any ideas where to look?

Thanks,
Tilmann

Okay,
it turned out that the problem occurred when not all buckets were switched on.
Only 24 channels were active, the remaining channels were switched off.

With 24 channels active and "Solo Isolate" enabled for channels 41–48 and 49–45, the solo function worked perfectly.
Is this normal, or is it something that should be investigated further?

Thanks,
Tilmann
