This is a used ART Syncgen Project Series Wordclock Sample Rate Generator. I acquired it as new old stock several years ago. I used it only a few times, but I am now selling it due to equipment consolidation. As shown in photo 3, it comes with the original box and manual. The conversion pins in photo 4 (from left: protective cap, bypass pin, RCA conversion pin) are included as is, as I am unsure of the original quantity. I believe it can be used with audio equipment and PA equipment with clock terminals. Please consider it.
