Compatibility
Supported software versions
Cuore One connects to your Audiotec Fischer DSP and relies on the DSP's own software and firmware to communicate. ACO firmware is tied to a specific DSP PC-Tool version, so we test specific combinations of the two and publish our results below.
Our recommendation
- If you don't need to upgrade your DSP's software or firmware, don't — Cuore One works on the combinations confirmed here.
- If you do upgrade, use only a combination listed as Confirmed below.
- When a new version is released, don't rush to upgrade — wait until we've confirmed it here. A new version can change how the DSP communicates and, in some cases, leave Cuore One unable to connect, so anything not confirmed here is at your own risk. We add new combinations to this page as we validate them.
- If unsure, contact us before upgrading.
This page covers your DSP's software (DSP PC-Tool and ACO firmware). It does not refer to Cuore One's own firmware, which updates safely over the air through the DGA Control app.
Version combinations
Each row pairs a DSP PC-Tool version with the ACO firmware it requires — a PC-Tool version won't run until your DSP's ACO firmware matches.
