Avid Pro Tools HDX — 3-Card System with Sonnet Echo Express III
Three Avid Pro Tools HDX PCIe cards installed in a Sonnet Echo Express III Thunderbolt 2 chassis. Sold as a complete bundle only.
Cards and chassis have been in climate-controlled storage. Previously owned by composer Guy Moon (Fairly OddParents, Danny Phantom, Cow and Chicken). Pulled from his professional studio. Signs of being in a professional studio. Unable to fully test without a Pro Tools Ultimate license. When plugged into my computer the sonnet and all three cards were recognized by the OS. Chassis shows scratches on top and bottom panels from rack use. Front panel is clean.

- 3x Avid Pro Tools HDX PCIe cards
- Sonnet Echo Express III Thunderbolt 2 chassis
