  • 1Description

The Denecke JB-1 Syncbox Timecode Generator is an ultra-compact, lightweight syncbox powered by an internal LiPo battery lasting up to 150 hours.

Weighing only two ounces, the JB-1 includes an LED status and low/dead battery display. It provides an easy-to-use menu and is updatable via Mac or Windows using its micro-USB port.
