A novelty of the ADI-2/4 Pro SE is the option to use the Rear TRS Line Outputs independently from the XLRs, for channel 3/4.

Currently plugging ‘phones into front TRS 1/2 or 3/4 either mutes both TRS and XLR Line Outs, or non, there’s no option for separated 1/2 and 3/4 ‘Phones / Line switching.

In Detail:

“Mute v. TRS 1/2”
- it should be possible to NOT mute Line Out 3/4 if the option “Rear TRS source Ph. 3/4” is active and ‘phones are plugged to PH 1/2.

With “Rear TRS source Ph. 3/4” it should be possible to keep both path’s independent and still have the option to mute the Line Outs, independently.

So the functions “Mute v. TRS 1/2” “Mute v. TRS 3/4” should have the options: “Off”, “On”, “Both”, but only if “Rear TRS source Ph. 3/4” is on.

Connected to this:

For maximum flexibility the 3/4 path should get an additional I/O Menü “Line Output 3/4“, if “Rear TRS Source Ph. 3/4” is active.
Same like 1/2 has.
This way both path’s would be fully equivalent.
