As the hub of any music studio, the HD OMNI digital audio interface from Avid can be used to record high-quality instrument and vocal performances, while providing dedicated cue mixes for artists, monitoring their performance through a discrete mix. No need for multiple interfaces. Everything can be done within the single-space rack HD OMNI.
Overdub and foley recording capabilities are available for post production, in addition to the ability to create monitor mixes with up to 7.1 channels. Furthermore, the user can fold down mixes from 7.1 to almost any channel configuration subset required.
The interface features premium analog-to-digital and digital-to-analog converters that deliver high audio fidelity, extensive dynamic range, super-low jitter, and the lowest possible latency. Built-in sample-rate conversion and a soft-clip feature allow for worry-free performances, while Curv, a built-in soft-knee limiter catches even the fastest transients.
For those occasions when the Pro Tools software doesn’t need to be launched, or when you do not want to turn on the computer, the interface features as a built-in, customizable, 14-input monitor mixer, allowing for the continued monitoring of external sources, such as keyboards, drum machines, and digital music players, independently from the recording setup.
The interface provides maximum performance, dependability, and control of all inputs, outputs, and routing, right from the Pro Tools software interface. The interface and Pro Tools HD hardware will function with other DAW software via full support of Core Audio and ASIO drivers.
