d3 4U v2.5

The d3 4U v2.5 system is our flagship hardware solution providing industry leading integration and performance for the most demanding projects in the world.


Power for performance

The d3 4U v2.5 server is for those who need power, integration, storage, and flexibility for their productions. With graphics power capable of 12HD playback of any resolution, the d3 4U is a highly scalable solution for installations and productions which require synced pixel-perfect playback.
With four DisplayPort 2560 × 1600 outputs and two HD-SDI input cards the system is industry leading in its video processing capabilities.

Ships with the d3 software

d3 4U v2.5 servers come loaded with the latest d3 software. That means that you get exactly the same user interface and platform as d3 Designer but integrated into a dedicated hardware platform.
To run the show, just copy the project file developed in d3 Designer to the d3 server and fully utilise the next level of networking, integration, and optimised playback performance.
Together, the d3 Designer and the d3 4U server form a very effective workflow and production environment that will save you time and money with every show.

The d3 rack-mount is packed with input/output capabilities.
With 2 x Gigabit ethernet ports, you can have one Art-Net and one device network simultaneously. The 6 x USB 2.0 slots give you the external device or backup hard-drive access at super quick speeds. Firewire 400 and 800 is there in case you need it, plus 2 x COM ports for those who prefer analogue. d3 is DMX (via Art-Net), MIDI, OSC and serial compliant.

Industrial Ruggedised Components

d3 systems are built on industrial components, so they are rugged and hardy, even in the long term.
Our chassis is among the most rugged cases on the market, with special customisations to make sure the internal components stay where they should, even if you bounce it around the country on the back of a truck.
Only industrial components are in the d3 product range, developed over years by people like you, we are committed to continuing to offer the right product for the job.


Graphics Power

The d3 4U v2.5 features the very best ATI 4 output digital GPU, featuring 2Gb VRAM, with up to 2560×1600 DisplayPort or 1920×1200 DVI (using the active DisplayPort adapters provided).
d3 4U’s graphics card is so powerful, you can cross-fade 2 × 8k video files while running through a sequence of 8k png images, and simultaneously scrub up and down the time-line without skipping a frame.



The on-board synchronization module allows the GPU to be used in demanding applications that require synchronization to external sources (Genlock) or synchronization multiple GPUs in different systems (Framelock), even across multiple machines.
This combination means that the user can guarantee Framelock across outputs, across multiple machines, while all the time locked to the single reference of your choice.


Latest i7 Processor

The new 4U 2.5 System comes equipped with the very latest Intel Core i7, featuring 4 cores with 8 concurrent threads when using Hyper-Threading, it operates at 3.40GHz, and is designed to work with DDR3-1333 memory and feature an 8MB L3 cache.
This means you are no longer limited to only our proprietary DXV codec for 4k and above textures, where the previous limit was 6 × 1080p using the GPU decompression technique. Now you can also use .pjeg and even .anim in multiple layers with this kind of performance.


Flexible Video Input

The d3 4U offers video capture from uncompressed 8-bit and 10-bit HD-SDI and standard definition SDI cameras.
With two card installed as standard, you’ll get up to 2 x HD-SDI or 4 x SD-SDI per machine, as multi-channel capability allows simultaneous capture from two independent SDI cameras, or to switch between two HD-SDI cameras on each card.
Supports 525 NTSC, 625 PAL, 720p and 1080i; SMTPE 292M, SMPTE 344M and SMPTE 259M.


Solid State Media Storage

Built with the quality, reliability, and durability that lives up to the OCZ name, the Vector Series easily integrates into the d3 System and features TRIM support to optimize performance over the drive’s lifespan as the ultimate Windows 7 companion.
With read rates of up to 550Mb/s this device will give you the ability to store more, play more and deliver more.


Removable Media Drives

Both 2U and 4U feature a 4 bay removable Media Drive array, meaning you can swap your drives around at will.
Coming as standard with a single 480Gb SSD there is plenty of room for all that high-res content. But, when you want to back up, quickly swap out a show, duplicate or copy, just add another drive to the media drive bay for instant access to complete peace of mind.


Broadcast Quality Audio

The d3 4U contains the world’s most versatile PCI Audio Interfaces: 192 kHz AD- and DA-converters with more than 110 dB signal to noise ratio, all inputs and outputs simultaneously operational and easy-to-install optional hi-quality analog expansion boards.
With balanced XLR in/out analogue audio, you can use its on-board MIDI interface to sync to MTC, LTC or receive MIDI notes or MSC for complete show integration.
