Follow these checks in Audio Fix →When this guide applies
Exact iFi ZEN CAN 3. ZEN CAN3 current analog source actively works and the intended destination is also already connected correctly. Front conventional headphones only, xMEMS OFF and rear line output unused.
Connection scope: Analog line / headphone audio. Symptom: Switching between devices isn’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.
scope
Confirm the model and connection
ZEN CAN3 current analog source actively works and the intended destination is also already connected correctly. Front conventional headphones only, xMEMS OFF and rear line output unused.
Look for: Confirm this exact setup and observation before continuing.
- If Yes, I confirm → Accept changing the analog source?
- If No / my setup differs → Continue with source and model support
- If I cannot confirm → More information is required

Accept changing the analog source?
Input switching interrupts current media. Continue only outside calls/recordings with agreement to pause both sources and lower headphone level first.
Look for: Explicit informed acceptance is required before the next action.
- If I accept these effects → Pause both sources
- If No / leave this unchanged → Continue with source and model support
- If I cannot confirm → More information is required

Pause both sources
Pause the actively connected source and intended destination media.
Look for: Observe the named indication or available control; stop if absent.
- If I completed this check → Lower the headphone dial
- If I cannot complete this → Continue with source and model support
- If I cannot determine this → More information is required

Lower the headphone dial
Reduce the analog volume dial; rear line output must remain unused.

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
