Firmware v2.3.0 has been released, adding a new speaker polarity testing function to Sync-One2.
The polarity of speaker wiring may be easily verified using a specific test file. By holding Sync-One2 close to each speaker in turn, the polity will either be given as Positive or Negative. The aim is that all speakers should identify the same polarity.
This new feature is a free upgrade for all Sync-One2 v2 users. A simple firmware update is all that is needed.
