The SBOX-1N Highly Accurate TC & WC Generator from Betso is an extremely accurate, very compact, and affordable time code and word clock generator. Its main advantages, not-to-mention being the industry leader in time code sync precision, are its surprisingly easy to use “plug and play” feature, along with its 1″ large LED display and well-designed power consumption optimization. With SBOX-1N you will never be out of sync again.

All Time Code and Word Clock Formats

The SBOX-1N can receive, precisely jam, or start to generate new time codes of all existing SMPTE time code formats.

Also, all commonly used word clock formats are supported, including their pull-up and pull-down options.

Extremely Easy To Use

To use, simply connect the cable to the active time code and leave the rest to SBOX-1N!

The automatic turn-on and jamming function provide the most user-friendly and reliable time code syncing as the SBOX-1N will automatically distinguish correct time code format, calibrate internal TCXO to obtain the same time base as your source, and start generating jammed time code.

You will find the time code synched to the source within less than 0.5 frame drifts even after two days of continuous use.

Ultra Highly Accurate TCXO

Embedded high precision temperature compensated crystal oscillator TCXO with frequency accuracy off 0.2 ppm is the fundamental piece of hardware for stable and accurate time code and word clock generator.

The superior quality of TCXO is best suited for changing environmental conditions where temperatures vary a lot during the day. Even in extreme weather conditions, the SBOX-1N will keep time codes in sync.

TCXO Calibration

Thanks to Betso’s sophisticated software methods, the ultra-highly accurate TCXO can be further calibrated to achieve much better than 0.2 ppm accuracy. These methods can be applied both during jamming, when TCXO is calibrated to obtain exactly the same time base as the source of time code or during calibration, from BETSO GPS-1 devices which offer calibrating based on GPS atomic clocks.

This accuracy is almost impossible to beat. And, as you know, accuracy is what TC syncing is all about.

Top Build Quality

Thanks to precise CNC milling manufacturing technology, anodized aluminum alloy materials, original hi-quality connectors, and other components, the SBOX-1N is very durable but still versatile.
