The HD I/O 16×16 Analog from Avid is a high-performance Pro Tools HD Series audio interface that is designed to completely integrate with Pro Tools HD systems. Available in three different configurations, this version provides the maximum in analog input and output. Since the interface utilizes all four card slots, expansion is not possible, but customization is.
Although it bears a physical resemblance to previous interfaces, the HD I/O has been completely redesigned with high quality converters and premium input and output circuitry. The interface provides maximum performance, dependability, and control of all inputs, outputs, and routing right from the Pro Tools software interface.
