Sync-One2 has undergone a major refresh and become Sync-One2 v2. Highlights of the changes are an Audio input port, USB-Mini B for data logging with an API interface for remote control / automation.
- Work in Post Production, need to ensure your
workspace is correctly setup and your workflow doesn’t introduce any synchronization problems?
- Professional AV installer needing a quick and easy way to check spaces for correct synchronization?
- Lip-Sync problems in a theater / home cinema?
- Offer TV color calibration, thought about also providing an enhanced service with audio synchronisation checks?
- Works with any output device, i.e. TVs and Projectors
Sync-One2 version 2 measures audio visual (or lip-sync) delays / errors and so help you
make the correct adjustments to ensure everything remains in sync,
without resorting to guessing. It accurately measures the time span
between an audio beep and video flash (e.g. a 2-pop / flash frame or
similar), giving the length of the delay and if the audio leads or lags
with reference to the video. With this reading you can set the audio
delay in an AV amp or audio delay unit, adjust your workflow, or be
assured everything is OK. Sync-One2 version 2 displays the error, in
milliseconds / frames, in real time, and enables a suitable adjustment
to be made quickly and easily. Statistics are also calculated on the
most recent 60 readings taken to help check overall system stability or
drift. More details on the features and specifications pages. Trying
to check any system manually is always prone to error, as it relies on
the subjective view of the person doing the testing. App based
solutions require manually assisted measurements, which are prone to
error and much less accurate. They also only take snapshot of the
system under test, which is not a true reflection of how a system is
actually performing. Sync-One2 is quick, easy, accurate, and an
essential tool for professional Audio Visual installers, post production
houses, and those interested in the correct setup of a home cinema, and
theatre environments.
General - Dimensions (H x W x D), 144mm x 90mm x 30mm (5.6" x 3.5" x 1.2”)
- 165g (5.8oz) excluding batteries
- 16x2 OLED display for easy viewing, fast response, and low power consumption
- Operating temperature from 5 to 50 Celsius (41 to 122 Fahrenheit)
Power - 2 x AA (LR6) batteries, rechargeable AA batteries are fine too
- Reverse battery protection
- Battery life from standard AA batteries is around 50 hours of continuous operation
- A
tiny current of less than 0.1 micro amps is used when off. Even so
when not being used for a while it is always best to remove the
batteries
- Low battery indication and auto shutdown when batteries become too low to maintain accuracy
Accuracy - Measurement of audio visual delay up to ±750 milliseconds
- Display
is rounded to the nearest 1 millisecond or 1/100th of a frame, internal
timing resolution of 0.05 milliseconds between light and sound pulse
- Self calibration adjusts for ambient noise and light, including fluorescent light flicker
- Automatic microphone gain adjustment during calibration process

For a generic quick test, there is a test file available on YouTube by clicking here (opens a new window), by clicking on the embedded video below, or a downloadable version of the file is available here
(right click and Save As). The test file is 1080p at 24 frames/second
using the H.264 Codec with a 10 second lead in, followed by a synchronized flash and beep every 2 seconds and lasts for 60 seconds in
total. A wider selection of test files, in a variety of resolutions, frame rates, and codecs are available for download from the Test Files page. A general FAQ over Sync-One2 and synchronisation in general can be found here.

Features
- Easy one handed operation, systems can be checked in a couple of minutes
- Measurement of audio visual delay up to ±750 milliseconds (or 2/3 of a second)
- Self calibrating to help reduce false readings from ambient light and noise
- Output
in milliseconds and also, if required, in frames to an accuracy of
1/100th of frame for any rate input between 1 and 99 (readings over 10
frames are displayed to 1/10th of a frame)
- Real time output in milliseconds / frames, a rolling real time average can also be displayed in milliseconds or frames
- Easy to read 16x2 OLED display with a wide viewing angle
- Large number display option for easy reading when taking measurements
- Buffer
of the most recent 60 readings, with statistical analysis including
average and span in milliseconds and also in frames if required.
Readings can also be removed from the buffer as required
- User adjustable offset can be applied to readings, up to ±99 milliseconds and if a frame rate is selected also in frames
- Adjustable
sensitivity levels for audio and video, default is the most sensitive
setting with four lower settings available for each
- Detection test for setup assistance when testing, shows when audio and/or video input is triggered
- Speaker distance input for correction of readings in large spaces, such as lecture theatres, up to 20m (65’ 7”)
- Easy to use menus to set the various options and functions
- Settings and options stored in flash memory so retained even if the batteries are removed, memory buffer is cleared at shutdown
- Runs on common AA (LR6) batteries, including rechargeable
- Low battery indication, with automatic shutdown if they get too low
- Adjustable inactivity shutdown from to 1 to 60 minutes, which can also be disabled if required
