Product Description


Sync-One2 gives you, in real-time, the audio-video (lipsync) delay/error in a system such as ProTools or Premiere Pro, Digital Audio Workstation (DAW), a digital or home cinema, an installed AV system, or anywhere where the audio and video take different paths.  You see the error in milliseconds and frames.  Automatically calculated statistics show you the true status of a system.


As display and audio technologies move to more complex and higher resolution systems (4K, UHD, HDR, Dolby ATMOS etc.), the processing requirements can easily cause AV synchronisation issues.  In addition, each component change, software, or firmware update has the potential to alter the AV sync in a system.  Watching content with poor AV sync is one of the most annoying and complained about problems.

Sync-One2 accurately measures the period between an audio beep and video flash (e.g. a 2-pop / flash frame or similar, clearly displaying the delay and if the audio leads or lags with reference to the video.  The error is displayed in milliseconds (1/1000th of a second) and, if desired, also in frames, in real-time.   You may also enable a running average to potentially average 1000s of readings, which is displayed in milliseconds or frames.  A memory buffer of the most recent 60 readings, including average and span statistics, is available to help check overall system stability or drift.

From firmware, v2.3.0 Sync-One2 v2 also offers speaker polarity testing,

Sync-One2 will work with any resolution or type of display, so it is 4K / UHD / HDR-ready, OK with LCD, OLED, Plasma, and Projectors.

  • Self-calibrating to help reduce false readings from ambient light and noise
  • Additional support for testing in spaces with long reverberation times
  • Real-time output in milliseconds/frames, You can also display a rolling real time average in milliseconds or frames
  • Statistics are calculated automatically on the last 60 readings taken for average and span, in milliseconds and frames
  • Fast startup, ready to take measurements in just a few seconds
  • USB Mini-B port for data logging
  • API interface via the USB port to enable remote control, and to supply power
