10- and 12-bit, up to UltraHD and 4K 60p

AJA's T-TAP Pro provides video professionals with an inexpensive, extremely compact device that utilizes the power of Thunderbolt 3 to deliver high-quality 10- and 12-bit up to UltraHD or 4K 60p video and embedded audio output from any compatible Mac or PC.

HDR Support

T-TAP Pro directly supports HDR dependent monitoring workflows across a number of HDR formats, including HLG (Hybrid Log Gamma), PQ and HDR10, with support for Dolby Vision possible via additional third party application integration. 

AJA’s Desktop software v16 now offers HDR over SDI with VPID signaling of SDR and HDR characteristics. A new HDR Tab in AJA Control Panel, now signals HDR over both SDI and HDMI simultaneously.

For playback, AJA Control Room reads HDR metadata embedded in .mov files and uses that to auto-set Control Panel to signal HDR accordingly, simplifying the workflow chain.

With T-TAP Pro and the appropriately captured/rendered HDR files, AJA Control Room can automatically detect the HDR format and T-TAP Pro can automatically adjust it’s output accordingly via both 12G-SDI or HDMI.

4K Closed Caption Support

AJA Control Room software now supports ingest and playback of 4K content that carries Closed Captions when using T-TAP Pro.

Thunderbolt 3 Connectivity

Simple to set up and use, T-TAP Pro’s Thunderbolt 3 port easily connects to a wide range of Apple and Windows laptops and desktops, providing instant professional video and audio output from your favorite creative application.

Thunderbolt 3 is ubiquitous across both Mac and Windows computers, and supports the massive bandwidth needed for professional 4K video, audio, data and more.

Professional Outputs

T-TAP Pro features 12G-SDI and HDMI 2.0 outputs. The SDI output can be used to feed professional monitors or recording gear, while the HDMI output is able to feed directly into consumer HDMI monitors. Both HDMI and SDI are active at all times, so you can simultaneously work with professional and consumer monitors.

Easy Integration

T-TAP Pro offers immense power in a very small footprint and features industrial design for silent desktop operation. This workflow example shows T-TAP Pro at the heart of a feature rich system, with a host laptop providing Thunderbolt 3 connectivity between the two. Broad software support means that T-TAP Pro can output video from the timeline of your NLE or post production software simultaneously via the 12G-SDI and HDMI 2.0 outputs, here shown as an AJA Ki Pro Ultra 12G digital video recorder and a standard 4K/HDR compliant HDMI consumer monitor. Streaming content can also be enhanced, allowing an editor to share their NLE timeline output directly with viewers in real-time, at any resolution required up to 4K 60p via the appropriate third party software.

Flexible Audio Control

With T-TAP Pro, a 3.5mm stereo analog audio connection is available on the front left of the device for headphone monitoring. This is an invaluable feature for editors or digital artists working from home, easily creating privacy with no compromise to performance. You're able to plug in headphones directly, or else route the signal to an external analog audio mixer for more options. T-TAP Pro provides an elegant solution to monitoring audio with off-the-shelf tools readily available, and also avoiding cumbersome dis-embedding.

As with other AJA Thunderbolt-connected devices, the monitor audio presented is selected via AJA Control Panel and is controlled via the Audio Setup Tab. Any pair of channels can be monitored from 1&2 to 7&8 up to 15&16 with a single click and selection. The diagram above shows the signal flow and control options for T-TAP Pro.

The front panel of the T-TAP Pro also features audio reference meters to further enhance it’s monitoring capabilities.

Extensive Software Support

T-TAP Pro is compatible with a broad array of software, including but not limited to Apple Final Cut Pro, Adobe Applications such as Premiere Pro and After Effects, plus Avid Media Composer and Pro Tools. AJA’s driver support ensures that you are up and running with the latest releases, with an ongoing commitment to future updates and enhancements via free, new firmware updates.
