Output board

Modula SDI Digital Video enclosures are built to hold up to sixteen boards.

Although primarily used for SD-SDI and HD-SDI digital video boards, enclosure

34-33 can also hold stereo audio boards (each with four stereo pair connectors).

Each enclosure holds a maximum of eight input and eight output boards,

accommodating connector configurations up to a maximum of 32x32, as well as

subsets (for example, 12x4 or 8x32).
