Qualified SCSI HBA Cards — Pro Tools|24 MIX Systems for Windows XP

For maximum track count, use of a qualified SCSI HBA (Host Bus Adapter) card is required with Pro Tools|24 MIX systems.

The following cards are officially qualified with Pro Tools MIX systems on Windows XP:

Digidesign SCSI|128 Kit /ATTO EPCI-UL3D (Dual Channel Ultra3 SCSI Host Bus Adapter - Model # EPCI-UL3D-000)

• Supports up to 64 tracks of playback and record with Pro Tools|24 MIX Systems
• ATTO ExpressPCI driver and firmware v1.68, available from www.attotech.com/software
• Before upgrading to ATTO 1.66 driver and firmware, disconnect all drives attached to the ATTO SCSI controller card
• Sync Rate set to "160DT (80)" (160 MB/sec at 80 MHz)*
• PCI Burst Rate set to 32*
• Selection Timeout: 16ms*

*Settings available via SCSI BIOS

Note: The 66MHz version of the ATTO EPCI-UL3D (model # EPCI-UL3D-066) is not supported for use with Pro Tools systems, regardless of whether your Pro Tools system is installed on a 33 MHz or 66 MHz PCI bus. The 66 MHz version is tuned for performance on a 66 MHz PCI bus. However, when Pro Tools is installed in a 66 MHz PCI bus, it reduces the speed of the PCI bus to 33 MHz. As a result, you will receive superior performance with the 33 MHz UL3D, because it is tuned for a 33 MHz PCI bus.
