16 x 1 HD SD SDI Video with Analog Audio Follow, (OP/B)

The AVS-816/HDA is an HD SD SDI video switcher with Analog audio follow. This unit is a wide bandwidth video/audio vertical interval switcher designed for the video professional in mind. It features compact modular design which allows it to handle HD SD SDI video and analog audio. The unit has sixteen channels of HD SD video and stereo audio. Digital and analog switching modules for both video and audio may be mixed in any combination for complete system flexibility. The inputs are non-looping and offer outstanding return loss performance. For HD SD digital applications, an optional analog monitoring output is available for analog audio.

Audio and video break-away are selected by a single switch on the front panel. Dual LED’s on the source selection and follow switch indicate follow or break-away. The AVS-816/HDA allows the user to efficiently and economically route or delegate multiple video and audio signals.

The analog audio inputs use standard 3-pin Weco connectors. The Weco 3-pin connectors are fast disconnect for ease of setup.

The analog audio I/O features full transformer isolation to eliminate the possibility of ground loop interference. Switching is accomplished during the vertical Interval by using the vertical sync derived from the video at the output stage. In a similar fashion, digital audio switching takes place during the audio sample preamble. Up to 32 switchers can be controlled by the computer software.

The AVS-816/HDA may be controlled by a serial data feed of either RS-232 or RS-422/485 interface standards, selectable by a simple internal DIP switch. A remote control panel is also available which utilizes the common RJ-11 modular connector along with the RS-485 interface standard. For automated system applications, an optional GPI interface is available.

The serial communication protocol is compatible with existing Link video and audio switchers and remote control panels. For integration into existing systems, the AVS-816/HDA can be preset to respond to that instruction set as well. The AVS-816/HDA meets SMPTE 310 and DVB-ASI specifications.
