The TASCAM CG-2000 Video Sync Master Clock Generatorfrom TASCAM CG-2000 Video Sync Master Clock Generatoris specifically designed for the needs of broadcasting and post production. An OCXO (oven-controlled crystal oscillator) is used for its high precision and because it's not affected by the temperature of the environment. With a clock frequency precision of 0.01 ppm the unit delivers high-precision synchronization with a frequency stability of +/-0.005 ppm or less per day.

The unit is equipped with an external input connector that supports a 10MHz signal that allows it to be connected to a rubidium clock or GPS clock for even higher precision. External clock jitter is reduced using an original circuit design that incorporates a high-performance video clock generator engineered with a FPGA and a PLL (phase-locked loop) circuit with a discrete filter. This enables a stable clock signal to be provided to the video/word outputs, improving system stability.

In addition to twelve Wordclock outputs and four video outputs, the digital outputs include two AES3/AES11 and two S/PDIF outputs, making this unit useful for large-scale audio/video synchronization systems and a wide variety of other applications. Of the twelve Wordclock outputs, two also support x2 Fs, x4 Fs and 256 Fs output, enabling them to be used in systems with Pro Tools and other DAW software.

The unit features multiple functions to support maintenance and the identification of issues if problems occur, allowing the device to provide troubleshooting support. Additionally, a logging function enables issues to be listed, and saved to a CSV file format on a USB flash drive. A self-correction function allows users to conduct maintenance using an external signal input and simple operations.

The GC-2000 provides redundancy for the power supply and the video/audio clock, as well as alarm outputs in the event an error occurs. Amphenol BNC connectors on the chassis use nuts for coupling for extra durability, along with a single circuit board used for each connector. This provides good resistance to the twisting and pulling of cables, and the suppression of interference between connectors.

Q: 1. We lost the power supply to our sync gen, do you sell them? What type of plug does it take? Our 12v power supplies don't fit.

A: The replacement power supply for the Blackmagic Design Sync Generator is listed below. Blackmagic Design PSUPPLY-INT12V10W Power Supply for Mini Converters BH #BLPSMC

Q: 2. So can this generate a time (clock) sync to my 4 BM hyperdeck studio minis? so they all receive the same time whether they are all recording or not? So if one of the rec deck starts recording a later time it will match the other recorders that are currently recoding ? Assuming they are all connected to this device?

A: this is NOT a timecode in a (sync)generator. There is no external timecode input on the Hyperdeck Mini if you would like to embed time code it would have to be imbedded directly into the video using something like the Tentacle Sync Sync E Timecode Generator.

Q: 3. Is there a rack mount bracket for this?

A: Yes! Connectronics 1U Rackmount for Blackmagic Mini Converters - Works Great! Holds 4 Converters.

Q: 4. Do I need to download software for using Sync Generator for Synchronize 4 pieces of Hyperdesk Studio 12G Recorder?

A: No.

Q: 5. How to set the Generator to 1080i60 tri level in this case? I can't find the setting in the manual. There is 1080i 50. No 1080i60 tri level.

A: Page 86 in the manual shows the settings for 1080i60.

Q: 6. If you have more than 6 devices, can you daisy-chain these units?

A: No, these units aren't designed to be daisy chained.

Q: 7. Will this model also have the same limitation of U.S. models being restricted from monitoring during recording?

A: Yes, the Tentacle Sync Sync E Mk2 Sync E Timecode Generator with Bluetooth (Dual Set) has the restriction on monitoring while recording.

Q: 8. BM Website says framerates include 1080/59.940p and 1080/60p, however B&H only lists specs going up to 1080/59.94 interlaced. Is this product listed an old model?

A: It does support 1080P.

Q: 9. Will this give me clean switches on a Blackmagic 16x16 3G HD-SDI switcher?

A: Hi there... I am the user of this Sync Generator but i am not the expertise... As far as i use this, this BM Sync Generator can act same like other Masterclock / SPG... which is to synchronize / lock all the devices (such as camera basestation / vision mixer / universal converter) that need "Ref In" in your Multi-Camera Production system....

Q: 10. Can this Sync Generator support connect with 4 pieces of "Hyperdesk Studio 12G" (2160P / 60 frame) ? How to set the video format ? Just set to PAL or NTSC ?

A: Yes. You can set the Sync Generator to 1080i60 tri level in this case.
