Follow these checks in Audio Fix →When this guide applies
Exact iFi ZEN DAC 3. Front on/over-ear headphones work but need more level with PowerMatch Low. Rear outputs are unused; this is not sensitive IEM operation.
Connection scope: USB audio. Symptom: Playback is too quiet or uneven.
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 model and connection
Front on/over-ear headphones work but need more level with PowerMatch Low. Rear outputs are unused; this is not sensitive IEM operation.
Look for: Confirm this exact setup and observation before continuing.
- If Yes, I confirm → Accept the PowerMatch loudness risk?
- If No / my setup differs → Continue with source and model support

Accept the PowerMatch loudness risk?
The manufacturer warns that gain changes can damage hearing, headphones or speakers. Continue only with rear outputs unused, volume reduced first and agreement to stop for excessive level.
Look for: Explicit informed acceptance is required before the next action.
- If I accept these effects → Lower the volume dial
- If No / leave this unchanged → Continue with source and model support
- If I cannot confirm → More information is required
