At its core, Sync-One2 measures the time between an audio beep and video flash, such as a 2-pop/flash frame or similar. Displaying the delay/offset and if the audio leads or lags with reference to the video. The delay/offset is displayed in milliseconds (1/1000th of a second) and, if desired, in frames, all in real time.

You can enable a running average of readings displayed in milliseconds or frames, which can average 1000’s of readings.  A memory buffer holds the most recent 60 readings to check overall system stability or drift. Statistics are calculated for average and span, available in milliseconds or frames.

Sync-One2 v2 also offers speaker polarity testing from firmware v2.3.0 or above.  All firmware updates, including new features, are free.

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.

Sync-One2 has the following features.

  • Simple one-handed operation, turn on Sync-One2, and it’s ready to go
  • Easy to read OLED display
  • Internal microphone and external audio input via a 3.5mm audio jack
  • A simple menu system to adjust settings and set options
  • Settings and options are retained, even if the batteries are removed, although the memory buffer is cleared at shutdown
  • 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
  • The ability to add a custom startup splash text via the API interface or Sync-One2 can be ordered with permanent startup splash text.
  • Firmware is upgradeable for new features and bespoke customisation is available.
