A robust and reliable solution for video and audio synchronization, the Gen-Lock to Analog Black Burst Module, 1x Loop & 1x Buffered Out, is a high-quality product from the reputable brand, Link Electronics. This advanced module, also known as the 812-OP/C, is designed to accept an analog black burst signal and genlock to an external source, ensuring seamless synchronization of your equipment.
The 812-OP/C is strategically placed in slot number two, serving as the primary sync generator for all other modules in the system. This innovative device produces the necessary lock pulses for all modules in the chassis, ensuring a harmonious operation of your audio and video equipment.
The module's advanced technology includes a phase-lock-loop with an LED indicator that signals green when a horizontal lock is obtained and red when no lock is obtained. This feature ensures the stability of your system, providing real-time feedback on the synchronization status.
The 812-OP/C analog genlock module also features a complex programmable logic device that generates all necessary pulses for the rest of the modules. This device takes in stripped vertical sync and field identification pulses, resetting appropriate counters within the device to develop output pulses that are in proper time and phase with incoming video.
One of the standout features of the 812-OP/C is its video presence detector. This feature controls whether the module is in genlock or free-run mode, with a bicolor LED serving as a video presence indicator. The LED turns green when video is present and red when there is no video, providing a visual cue for the operator.
In the absence of video, the module automatically switches over to a free-run frequency condition. The frequency of the 27 MHz oscillator can be adjusted using a front panel control, which changes the DC voltage of the VCXO. This ensures that the module can adapt to different operating conditions, providing flexibility and reliability.
The 812-OP/C genlock module offers three ways for reference source selection: automatic switch over to its internal reference source when there's no video, manual switch over to its internal reference source, or applying video with the AUTO/INT switch placed in AUTO mode. This versatility makes the 812-OP/C a reliable choice for a wide range of audio and video synchronization needs.
In conclusion, the Gen-Lock to Analog Black Burst Module, 1x Loop & 1x Buffered Out, is a durable, reliable, and high-quality product that offers advanced features and innovative technology for effective audio and video synchronization. Its high review count and reputation as a product from Link Electronics further attest to its effectiveness and reliability.
