AJA Software & Utilities
Io X3 operates with AJA’s Desktop software package, developed for powerful integrated video/audio capture, editing, and production with a variety of 3rd- party software. AJA software is distributed as a unified package which includes all the software, firmware, plugins, and utility programs for the Io X3, as well as AJA’s Io, KONA, and T-TAP products.
Two retail packages are available, one for Mac and one for Windows.

Mac and Windows Packages

These packages include:

Drivers
AJA device drivers for tightly integrated hardware/software operation.

AJA Control Panel
The Control Panel provides:

Source selection and control of your AJA hardware.
A block diagram to show visually what routing and processing is being performed.

AJA Control Room
Control Room is a cross-platform software application for capture, playback and output with AJA products.

AJA System Test
AJA System Test is a utility for measuring system performance. The application includes:

System Disk Test
AJA Device Test
System Report
The application tests Read and Write, Capture and Playback speeds tests in both Megabytes per second and Frames per second. The disk speed tests differ from standard disk I/O performance applications in that they specifically test the system under conditions typically encountered with video capture, playback, and editing.
NOTE: Theoretically the best test is to fill your storage disk to 80% and then test capture at the highest data rate you will use.

3rd-Party Plugins
Plugins for popular 3rd-party Professional Video Applications from Adobe, Avid, Apple, OBS, Telestream, and others.

System Requirements

NOTE: On macOS, the Io X3 supports Apple’s M1 chip, as well as earlier Intel processors.

Cable Connections

Connector Descriptions

Thunderbolt 3
The Io X3 provides the third-generation Thunderbolt 3 (USB-C) ports to support increased bandwidth between host computer and I/O device. Two ports are provided for daisy-chained network configurations.
The left port with the special logo is meant to identify the downstream Thunderbolt 3 port. The port on the right with the standard logo is meant to indicate the upstream port that is to be connected to the host computer. Despite a regulatory need to label one of these ports as downstream, the Io X3 actually has a fully symetric Thunderbolt implementation. Either port can be used for either an upstream or downstream connection.

NOTE: Io X3 does not support host computer charging through the standard logo ‘upstream’ Thunderbolt port.

Bi-directional SDI I/O
Four bidirectional BNC connectors can be configured in a variety of ways via the AJA Control Panel, including:

Two HD/SD inputs (SDI 1 and SDI 2) and two outputs (SDI 3 and SDI 4)
Four HD/SD inputs (SDI 1, SDI 2, SDI 3, SDI 4)
NOTE: Some third-party applications (examples: OBS Studio, Wirecast, Vmix) may support other input/output configurations. Please see the relevant AJA Quick Start Guide document for the application you are using.

HDMI Input and Output

Two HDMI connectors provide input and output of HDMI video and multi-channel embedded audio.

HDMI 1.4b input and output (using HDMI 2.0 implementation) supporting resolutions at up to 60p (4:2:2), 10-bit
Supports two or eight channel HDMI audio input and output
HDMI output also supports:
HDR 10 Support – HDR Infoframe metadata, compatible with HDMI 2.0a/CTA-861.3
HLG Support – compatible with HDMI 2.0b/CTA-861-G
NOTE: HDCP is not supported on either input or output. HDMI output does not have HDCP, and input sources having HDCP are not supported.
The HDMI input is designed to support long cable runs—up to 100 ft. when using 22 or 24AWG HDMI cable, or up to 50 ft. using 28 or 30AWG HDMI cable. The HDMI output supports standard HDMI cables only.

RS-422 Machine Control
A female DB-9 connector provides connection for VTRs, camcorders, disk media servers, and other devices using RS-422 SMPTE (Sony) protocol.

Reference Video
A dedicatec BNC connector provides reference Input. Supplying a reference signal to the Reference input allows you to synchronize Io X3 outputs to your house analog reference video signal (or black burst). When connecting a reference video source, the locking signal should be the same as the input format. It is possible in some circumstances to use an alternate format video signal as long as the basic frame rate is compatible.

LTC Input and Output
Two BNC connectors provide dedicated LTC input and output.

Balanced Analog Audio Input and Output
A 25-pin connector provides 8-channel balanced analog audio, 24-bit 48kHz sample rate D/A and A/D. This will require an industry standard 8x XLR on DB-25 breakout cable (not supplied). The eight analog audio channels can be configured four different ways:

Ch 1-8 Output
Ch 1-4 Input and Ch 5-8 Output (default)
Ch 1-4 Output and Ch 5-8 Input
Ch 1-8 Input

12V Power Connector
A standard 4-pin XLR type connector is provided for either battery or line source power using the supplied AC power adapter.

Installing Software

NOTE: If your computer has previously had another video capture or multimedia device installed, ensure you uninstall any related software before installing Io X3. This will prevent any hardware or software conflicts.

Before installing the software package, ensure that your capture/editing application is installed as detailed in its user documentation. Before using Io X3 an NLE application, it is best practice to have installed and run the software at least once on your workstation. Next, install the AJA software package.
If at a later date you add any Io X3 supported applications that require drivers, you must run the AJA install program again to install them.

macOS Installations
macOS High Sierra (10.13), macOS Mojave (10.14), macOS Catalina (10.15), macOS Big Sur (11.x) and macOS Monterey (12.x) all have security requirements that may present dialogs during installation. Please refer to the Release Notes for guidance.
