Follow these checks in Audio Fix →When this guide applies
Already working compatible desktop Universal Control, read-only firmware inventory.
Connection scope: USB audio. Symptom: I need to check firmware update requirements.
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 step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
step-0
Does the already installed desktop Universal Control identify this Quantum ES 2?
An unrecognised interface needs its actual USB/driver checks first.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Is no firmware installation currently running?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

Inspect Firmware in the Universal Control Start Page for this device
Do not click Update Firmware or reset controls.
Look for: Perform only the stated operation and confirm whether it was possible.
