Topic: ADI-2/4 Pro SE–Switching between 3 monitoring states

Hi everyone,

I’m trying to set up a mastering workflow on the ADI-2/4 Pro SE and would appreciate some guidance on whether this is possible (and the best way to approach it).

Constant routing (must stay always active)
USB Playback 3/4 → Rear TRS Outputs 3/4
This feeds my analogue chain and returns into Analog Inputs 1/2

This part works fine and should remain unchanged in all cases.

What I’m trying to achieve

I need 3 monitoring “states”:

State 1 – Main monitors (ADAT)

ADAT Out active
XLR 1/2 muted
Phones muted
TRS 3/4 stays active (insert return)

State 2 – Second monitors (XLR)

XLR 1/2 active
Phones muted
ADAT ideally muted BUT still clocking (my Trinnov Nova loses lock if ADAT is fully disabled)

State 3 – Headphones

Phones active (front TRS 1/2)
XLR muted
ADAT muted

Main issues / questions
Is there a way to store and quickly recall such output configurations?

Can ADAT be “silent” but still maintain clock (so connected monitors don’t drop)?

What’s the recommended way to handle multi-monitor switching on this unit?

Am I approaching this wrong—should this be done differently within the ADI-2/4 architecture?

The routing itself isn’t the problem—it’s the switching between these states that’s slowing me down.

Any advice or workflow suggestions would be greatly appreciated.

Thanks!

Re: ADI-2/4 Pro SE–Switching between 3 monitoring states

The HARDWARE optical digital interface you call “ADAT” is called TOSLINK.
TOSLINK can carry the digital formats “ADAT”, or “SPDIF”, which likely is the one you are using for your monitors.

The option:
• SETUP / Options / Device Mode/DSD / Digital Out Source: Main Out
sends the processed signal Line Out 1/2 to the digital outputs AES, SPDIF COAX and OPTICAL, for example to connect active monitors having digital inputs.

Switching between XLR 1/2 and SPDIF OPTICAL is done at:
• SETUP / Options / Phones / Toggle Ph/Line: Line/Digit
Clock stays active even if SPDIF is muted.

An IR Remote- or ADI-2 hardware-button can be assigned for fast switching between XLR 1/2 vs. digital outs:
• SETUP / Options / SPDIF/Remap Keys / Remap Keys: Remote or ON
• SETUP / Options / SPDIF/Remap Keys / [select key]: Toggle Ph/ Line

To mute the speakers to listen on phones PH 1/2:
• SETUP / Options / Phones / Mute v. Ph 1/2: ON
Plugging phones to PH 1/2 now mutes XLR / Optical, no key can be assigned to this.
