The Dcode SB-4 from Denecke is a compact and lightweight (at 4 oz) syncbox which generates, reads, and jam syncs timecode at all standard frame rates. It features a large display with a backlight, that allows you to comfortably read your timecode and settings, even in sunlight.

The SB-4 is equipped with an advanced Temperature Compensated Crystal Oscillator (TCXO) which offers ten times the frequency stability than that of the company's previous products, eliminating the need to jam more than once per day. The unit provides indication of drift/inaccuracy, a useful feature for troubleshooting bad timecode, and selectable output levels to easily match the sync input of other devices in your system.

The Dcode SB-4 is effortlessly controlled using a simple joystick/button, and runs on two AAA batteries or external power. It operates between 15 and 30 hours on a full charge.

Q: 2. Does this work with Sony FS5?

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

Q: 3. What's the best cable to sync timecode with a Zoom F4?

A: This Ambient Recording 5-pin Lemo to BNC will work: https://bhpho.to/3gmJdTq

Q: 4. 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: 5. 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: 6. Will this allow me to jam timecode if I am shooting on a URSA mini 4k (first edition) and recording audio to a Zoom H4N Pro (2020 edition)? any noticeable downfalls with this setup that you know of? Denecke said it would work with the URSA mini but didnt know about the Zoom H4N Pro

A: We are not aware of this working for that purpose.

Q: 7. 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: 8. 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.

Q: 9. 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: 10. Will this work with a bmpcc 4k and a canon c70?

A: We would only recommend using the Deneke Dcode SB-4 Syncbox Timecode Generator with a camera that has dedicated timecode ports. The Canon C70 does feature a dedicated timecode port through it's BNC adapter and would be compatible with this Timecode Generator.
