Broadcast-Quality Conversion
Io XT/4K features hardware-based full 10-bit broadcast quality motion adaptive
SD to HD up-conversion, HD to SD down-conversion and HD to HD cross-
conversion.
The quality of the conversion features is virtually identical to AJA’s award winning
stand-alone converter products used throughout the post production market.
TheIo XT/4K's built-in up converter uses a full 10-bit path, fully motion adaptive
de-interlacing, and large multi-point digital interpolators. Down-conversion uses
large multi-point digital interpolators, anti-alias filtering and interpolation.
Cross-conversion is high-quality hardware-based and offers true broadcast
picture quality in realtime. Because these functions are in hardware, they are
available full time, all the time—with no CPU load. Such conversions are useful for
cost effective monitoring, making standard definition dubs of an HD project, or
up-converting from a standard definition project to an HD deliverable.

Io XT/4K Audio
Io XT/4K provides up to 16 channels of SDI embedded audio. The front panels
have a mini TRS headphone output with a lockable level control knob.
Io XT/4K also supports HDMI Audio, 2 or 8 channels.
For analog audio output monitoring, Io XT/4K provides a DB25 connector with
eight channels of audio to be used with industry standard Tascam-style audio
breakout cables. The front panel has an eight-channel VU meter display to
monitor output levels.
Io 4K, when in 4K Mode, also supports monitoring mixed audio from Io 4K inputs,
host computer, and controlling application.
