The Denecke JB-1 Syncbox Timecode Generator is an ultra-compact, lightweight syncbox powered by an internal LiPo battery lasting up to 150 hours. Supporting all standard frame rates including 23.976, the JB-1 automatically senses the incoming timecode rate and features a single bidirectional BNC connector.

The JB-1 generates, reads, and jam syncs timecode, offering six preset and two user-selectable output levels. Its Temperature Compensated Crystal Oscillator (TCXO) eliminates the need to jam more than once per day. A large backlit display enables you to easily read your timecode and settings, even when shooting outside.

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.

Q: 1. Does this work with Sony FS5?

A: The Denecke Dcode SB-4 Syncbox Timecode Generator will not work with the Sony FS5.

Q: 2. What setting is used to output timecode to a Lectrosonics SPDR recorder?

A: To send timecode from the Denecke JB-1 Syncbox Timecode Generator, set the mode for Jam One (JO) and then set the Frame Rate as desired. Here is a link to the user manual: https://www.bhphotovideo.com/lit_files/644705.pdf

Q: 3. Do you need another device to wirelessly sync this to a camera like the Arri Amira?

A: Timecode generators with wireless communication can be paired with the Denecke TS-C Compact Timecode Slate (Color Clapper, EL Backlit) and camera for sync, such as from Tentacle Sync and those from Ambient. The Denecke TS-TCB offers wifi communication with timecode buddy products.

Q: 4. How can I get a new battery cell of JB-1?

A: You will want to reach out to Denecke for assistance with this issue. Tel: 661-607-0206 Email info@denecke.com

Q: 5. Can you use this with a tentacle sync box so you can use this on a c70 and the tentacle sync on a bmpcc 4k?

A: For best results, it is recommended to use matching timecode generators for maximum compatibility, for Tentacle systems and for Denecke Dcode SB-4 Syncbox Timecode Generator systems. For use with a Blackmagic Pocket Cinema Camera 4K and a Canon C70, we would recommend 2 of the Tentacle Sync units. Tentacle also uses a proprietary software for matching the jammed signals.

Q: 6. What cable do I need to jam time code into my RED DMSC2 with this device?

A: All you need is a quality SDI BNC to BNC cable. Here is one suggestion. Canare 1' L-3CFW RG59 HD-SDI Coaxial Cable with Male BNCs (Black) BH #CA35HSVB01 • MFR #CA35HSVB01

Q: 7. Does the TC-3 slate have this device built into it?

A: The Deneke TS-3 Time Code Slate reads and displays SMPTE/EBU Time Code; it utilizes an internally mounted SB-2 Syncbox Time Code Generator.

Q: 8. What happens with the timecode when I am recording at 60fps?

A: From the manufacturer; 60fps is the Video Frame Rate. The TC frame rate will be half of that. So, 60 fps Video = 30 fps TC. Please note, that many times the video frame rate is referred to as '60' when it is actually '59.94'. In this case, the timecode rate is 29.97fps. I have a strong hunch that this is the case here. 30\60 is very rarely used theses days.

Q: 9. What's the highest FPS for this timecode generator? 30 FPS?

A: This unit offers frame rates of 23.97, 24, 25, 29.97 and 30fps.

Q: 10. Will this work with Convergent Design's Apollo to insert time code when ISO recording?

A: according to the manufacturers manual connect the JB-1 to LTC I/O port, as long as you are using that time-code port as the selected time-code source, the time-code that's generated by JB-1 will be read and show up on the Apollo.
