TholusOS Enterprise
Everything you need. One system.
TholusOS combines multi-projection, playback, and daily operations. Set up the room once, then let the team open, schedule, and control it without rebuilding the workflow.
More than mapping
Content, playlists, preload, crossfades, loops, and immersive formats live in the same control room.
Easy for the whole team
Staff manage schedules, content, and playback without working directly on the media server.
Set up. Schedule. Open.
-
01
Synchronise the outputs
Connect the video controller, set the surface, and size up to 8 projectors for the required resolution, frame rate, and content.
-
02
Calibrate the surface
The assisted process prepares warp, blend, black-level, and colour maps consistently.
-
03
Load and schedule
Organise media and playlists, choose days and times, and let TholusOS start the session.
-
04
Manage it remotely
Administrators and operators control system health, content, and playback from a browser.
Multi-projector, without the complexity.
Outputs, calibration, and playback stay in the same project, from one surface to an immersive room with 8 projectors.
- Custom layouts from one to eight projection regions.
- Warp, edge blending, black-level compensation, and colour correction.
- Assisted calibration profiles for consumer, standard, and metric setups.
- Standard, equirectangular, domemaster, and mirror-dome output.
- Local playback with preload, crossfade, loop, seek, and hold-last-frame.
- Blending from two to eight projectors requires a compatible video controller: separate native Mac mini outputs are not genlocked.
The whole team can run the room.
The web console gives administrators and operators the right level of access. Content, schedules, and playback can be managed from any browser, even remotely.
Daily operations
- Content, playlists, and distribution to the media server.
- Weekly calendars, time windows, and overnight schedules.
- Play, pause, volume, next content, and event commands.
- A local staff panel available on the venue network.
Control and diagnostics
- Heartbeat, output state, and available storage.
- Calibration, download, and playback status.
- Administrator and operator roles for browser access.
- Safe restart and return to schedule after manual control.

Three plans. Start with what you need.
Core covers local operation. Pro adds remote control and interaction. Enterprise completes the system for larger installations and organisations.
Core
€9 / month €90 / 12 monthsContent library, playlists, scheduler, playback, and the local staff panel.
Pro
€19 / month €190 / 12 monthsCore plus event control, phone interactions, analytics, and multi-user remote management.
Enterprise
€39 / month €390 / 12 monthsPro plus white label, advanced diagnostics, and dedicated profiles for support and larger organisations.
Hardware, only if you need it.
Use a compatible Mac or add a preconfigured system. Blending from 2 to 8 projectors requires a compatible video controller; BTSX is the dedicated option.
Optional hardware
Ready TholusOS media server
€1,900
+ VAT
Configured Mac mini, BTSX controller for systems with up to 8 outputs, and one year of TholusOS Pro included.
- Ready-to-run hardware
- Blending for up to 8 projectors

Optional hardware
BTSX controller
€600
+ VAT
The controller sits between a compatible media server and the projectors, providing up to 8 synchronised outputs for blending.
- BTSX controller
- Up to 8 video outputs
- Media server and TholusOS not included
All prices exclude VAT. Projectors, installation, and on-site calibration are not included. Effective output count depends on resolution, frame rate, and content.
Questions before designing the system
Can I connect two projectors directly to the Mac mini?
For independent images, yes. For one continuous edge-blended image, no: separate native Mac mini outputs are not genlocked. The projectors can refresh at different instants, revealing tearing or discontinuities in moving content. Any blended system from two projectors onward therefore needs a compatible video controller that derives synchronised outputs from the same canvas.
What does the BTSX controller do?
BTSX receives the media-server canvas and divides it into as many as 8 synchronised outputs. Total resolution and frame rate must be chosen before installation for the content and projector count.
What contrast ratio should the projectors have?
For deeper blacks and less visible overlap, we recommend a real native or static contrast ratio of at least 2,000:1, preferably higher. Compare values measured with the same method, not dynamic-contrast claims in the hundreds of thousands or millions to one: those depend on an iris or light source changing between scenes and do not describe the simultaneous black performance required for a blend.
Can I use inexpensive projectors?
Yes, if they are chosen for static contrast, brightness in the colour mode you will actually use, suitable optics, stable inputs, and available overlap. High lumen output or a huge dynamic-contrast figure cannot compensate for raised blacks, poor uniformity, or the wrong lens.
Do all projectors need to be identical?
Using the same model and lens, consistent firmware, and light sources with similar operating hours is strongly recommended. TholusOS can correct geometry, gamma, black level, and colour, but it cannot fully remove large physical differences between projectors.
How do I prepare a stable blend?
Plan optical overlap before mounting. Run every projector at the same resolution, refresh rate, colour mode, and light-source setting. Disable dynamic contrast, automatic brightness, and self-adjusting corrections during calibration, then inspect white, solid colours, dark scenes, and real moving content.
Why can a seam appear in dark scenes?
A projector cannot emit absolute black, so the black floors of both images add together in the overlap. Compensation can even out the area, but it cannot create a black deeper than the projectors, screen surface, and ambient light allow. This is why static contrast and uniformity matter.
Is TholusOS only projection-mapping software?
No. It is a media server for permanent installations, combining mapping with playback, content, playlists, scheduling, commands, diagnostics, and remote operation.
Can several people manage the venue?
Yes. The remote console provides administrator and operator access, so the team can work from a browser without using the Mac connected to the projectors.
Which content formats are supported?
Standard, equirectangular and 360° video, domemaster or fisheye, mirror-dome workflows, playlists, and interactive Tholus experiences.
