Overview:

The Lassen HD routing switchers are designed for forward-looking broadcast and post production facilities preparing for transition to HD. The Lassen 88HD high definition video routing switcher employs mulit-rate video boards capable of handling standard serial digital video signals including SMPTE 310M, SMPTE 259M, SMPTE 344M, ITU-R BT.601 and DVB-ASI up to 540Mbps along with HD serial digital video signals conforming to SMPTE 292M (1.485Gbps single link). At 2RU, 88HD is ideal for remote production units and staging applications.
