LASSEN 88HD 8x8

LASSEN HD™ 8 SERIES ROUTING SWITCHERS

LASSEN HD 88 SERIES SERIES

HD-SDI AND SDI VIDEO.

DESCRIPTION

The Lassen 8 series are high performance routing switchers for SDI (SMPTE 259) and HD

SDI (SMPTE 292) video signals. These units come in a compact 2U (3.5”

)

frame and can

be ordered with or without 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.
