Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Exact Topping DX3 Pro+. Bluetooth input is already enabled and selected on this exact DAC. You want to pair one intended source and have the original remote; this is not a multipoint/mixing procedure.
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
Bluetooth input is already enabled and selected on this exact DAC. You want to pair one intended source and have the original remote; this is not a multipoint/mixing procedure.
Look for: Confirm this exact setup and observation before continuing.
- If Yes, I confirm → Accept interrupting the present Bluetooth link?
- If No / my setup differs → Continue with source and model support
- If I cannot confirm → More information is required

pairing-consent
Accept interrupting the present Bluetooth link?
Holding brightness on BT disconnects the current Bluetooth device and starts pairing. Continue only outside calls/recordings and if that interruption is acceptable. This is not a factory reset or permission to erase the source pairing list.
Look for: Explicit informed acceptance is required before the next action.
- If I accept these effects → Pause the old source
- If No / leave this unchanged → Continue with source and model support
- If I cannot confirm → More information is required

Pause the old source
Pause any connected Bluetooth media before deliberately entering pairing.
Look for: Observe the named indication or available control; stop if absent.
- If I completed this check → Hold brightness for pairing
- If I cannot complete this → Continue with source and model support
- If I cannot determine this → More information is required

Hold brightness for pairing
With BT already selected, hold the exact remote brightness button for 3 seconds to disconnect the current Bluetooth link and force pairing mode. Do not remove saved pairings or reset the unit.
Look for: Observe the named indication or available control; stop if absent.

Select the exact DAC
On the intended nearby source choose the exact DAC name in Bluetooth pairing settings, without selecting a similarly named different model.
Look for: Observe the named indication or available control; stop if absent.
