Tascam CG-2000 Master Clock Generator

The TASCAM CG-2000 is a professional master clock generator for broadcast, post-production, recording studios, live sound and large audio/video synchronisation systems. It uses a high-precision OCXO oscillator, jitter management and glitch-free relocking to provide stable clock signals.
