SYNNER144's unique flexibility comes from being able to use the board in three different ways.

CRYSTAL Vision's new synchronizer card combines a video synchronizer with the ability to track two audio groups along with an embedder or de-embedder and audio routing on one 100mm x 266mm module.

SYNNER144's unique flexibility comes from being able to use the board in three different ways using the audio piggybacks first developed for the TANDEM range of embedders/de-embedders. Without any piggyback fitted, SYNNER144 can accept an untimed feed of video containing up to two groups of embedded audio; and will time the video and audio to the user's system, as well as rearranging the stereo pairs in the embedded audio if required.

By fitting an audio input piggyback, SYNNER144 can accept an untimed feed of video and separate analog or digital audio and produce timed video and embedded audio. The stereo pairs can be shuffled or replaced, to create a new group of embedded audio or overwrite some or all of what is already present.

With an audio output piggyback fitted, SYNNER144 can take an untimed feed of video and embedded audio and produce video and separate analog or digital audio timed to station syncs. A 4x6 stereo router allows the user to select the stereo pairs to de-embed.

The internal audio delay tracks the video delay, running the audio faster or slower to maintain A/V timing and preventing lip sync errors. The new card also features CRYSTAL Vision's robust embedded audio protection. Frame drops or repeats of video synchronization do not affect the selected audio groups. It can also be switched to Dolby E mode to preserve Dolby E encoded audio through the synchronization process.
