The Denecke JB-1 features a display and menu system, which allows for ease of use and display of timecode and settings. It reads, generates and jam syncs to all standard frame rates including 23.976 for High Definition shoots. The JB-1 features an automatic jam sync capability, which senses the incoming timecode rate. Cross jamming of different rates can be accomplished as well. The advanced Temperature Compensated Crystal Oscillator (TCXO) has ten times the frequency stability than previous products, eliminating the need to jam more than once per day.
