When this guide applies

Exact RME ADI-2 DAC FS. ADI-2 DAC FS controls are disabled with the explicit Keys locked! message. Source media is paused. This is local UI unlocking, not firmware or a factory reset.

Connection scope: Device controls / power only. Symptom: Buttons, touch controls or wear detection aren’t working.

This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.

If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.

Checks and possible outcomes

Start at scope. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

Confirm the lock message

Confirm Keys locked! is shown; unknown display state must stop rather than force the controls.

Look for: Observe the named indication or available control; stop if absent.

Release UI lock

Press and hold upper encoder1 as the manual directs to unlock. Do not perform a power-on key combination, which can reset settings.

Possible result

More information is required

An unknown state is not a diagnosis. Record the last visible indication and consult the exact model instructions.

insufficient data

Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

    Possible result

    Continue with source and model support

    Keep the source, connection and last observation. Do not reset, open equipment or change full-scale output to compensate for an unconfirmed result.

    next support

    Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

      Possible result

      Checks completed

      The requested observation was confirmed in this setup. It does not establish a hardware repair or guarantee another source behaves the same.
