iFi ZEN One Signature: pair a new source with documented memory-overwrite consent
iFi ZEN One Signature — pair a new source with documented memory-overwrite consent. Use the stated exact hardware and connection scope.
Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Exact iFi ZEN One Signature. BT is selected and you want a new nearby source on ZEN One Signature. The exact physical unit can be identified and its fixed line outputs feed an amplifier with its own functioning level control.
Connection scope: Bluetooth. Symptom: My devices won’t pair or reconnect.
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
BT is selected and you want a new nearby source on ZEN One Signature. The exact physical unit can be identified and its fixed line outputs feed an amplifier with its own functioning level control.
Look for: Confirm this exact setup and observation before continuing.
- If Yes, I confirm → Accept BT interruption and possible oldest-pairing deletion?
- If No / my setup differs → Continue with source and model support
- If I cannot confirm → More information is required

overwrite-consent
Accept BT interruption and possible oldest-pairing deletion?
ZEN One Signature stores8pairings. Pairing a ninth deletes the oldest stored device, which must later be paired again. Continue only if you accept that possibility and interruption of current BT media, with downstream amplification muted.
Look for: Explicit informed acceptance is required before the next action.
- If I accept these effects → Pause current media
- If No / leave this unchanged → Continue with source and model support
- If I cannot confirm → More information is required
