The SCSI|128 kit, which includes the ATTO UL3D Dual Channel Ultra3 SCSI Host Adapter and two cables, accomplishes two significant tasks. First, it offers 128 tracks of record and playback with Pro Tools|HD on both Mac and Windows when used with LVD drives.Second, its built-in LVD support results in improved data integrity, and allows for longer cable lengths up to 12.5 meters (41 feet) per bus to accommodate effective placement of your LVD-supported SCSI drives in your studio environment.
