The Lassen 32 series are high performance routing switchers for SDI (SMPTE 259) and HD-SDI (SMPTE 292) video signals. These units come in a compact 3U (5.25”) frame and can be ordered with or without analog or digital audio. They can route any or all inputs to any or all outputs. HD-SDI models can input SDI and HD-SDI simultaneously, but there is no conversion between formats.
