Specifications

The following Video Signal Formats are supported by Io XT.

* Note: 720p@23.98 fps and 720p@25 fps are not "over-the-wire" formats. These frame

rates are contained within the larger "over-the-wire" frame rates of 720p@59.94 fps

and 720p@50 fps.

Io XT Audio

Io XT provides up to 16 channels of SDI embedded audio. The front panel has a mini TRS

headphone output with a lockable level control knob.

For analog audio output monitoring, I o XT 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.

Dual Link

Io XT supports Dual Link HD-SDI (4:4:4). Io XT supports the ingest and output of SMPTE-

372M compliant 4:4:4 RGB video and high-bandwidth 4:2:2 1080p 50, 1080p 59.94, and

1080p 60 at 10-bit.

Hardware-based Acceleration

Final Cut Pro 7 users will likely notice the DVCPROHD, HDV, and Apple RT Extreme hardware

acceleration provided by Io XT. This hardware acceleration was developed in close

cooperation with Apple. How does Io XT accelerate DVCPROHD, HDV, and Apple RT Effects?

A precision hardware scalar in Io XT does what the Apple computer's processor would

otherwise have to do, scale less than full-raster HD (DVCProHD and HDV) to full-raster size,

thus speeding up the system considerably—and doing this scaling at full 10-bit broadcast

quality.

When using the Final Cut Pro 7 HDV codec, the Io XT advanced scaling engine takes the

native frame (long GOP 1440 HD) and outputs it via hardware-in real time. Precision AJA
