Aputure INFINIMAT 2×4

Overview

The clear airbag is a physical support for interchangeable diffusion. Older INFINIMAT kits used a different softbox arrangement, so identify the supplied airbag and cloth before comparing published output or ordering replacement parts.

Strengths and limitations

Strengths

• A shallow diffused face is useful where a deeper softbox would obstruct the set.
• Removable diffusion, skirt and grid allow the output and spill to be adjusted as a package.
• Full-colour and pixel control support practical-light and moving-colour motivation.

Limitations

• This mat uses the full nominal 400W capacity of its standard controller. Spare physical sockets do not imply spare capacity for another mat.
• The lamp-mat weight excludes the controller, airbag, accessories and support.
• The inflatable component needs protection from abrasion, punctures and unsuitable contact surfaces.

Practical uses

Setup	Working approach
Single-person interview key	Place the long rectangle close to the subject, then feather and grid it to keep the background under control.
Over-table soft source	Use an approved overhead rig, skirt the face and meter each seat. A broad overhead source can still create eye sockets if its angle is poorly chosen.
Car or confined set	Plan around the complete inflated dimensions and available mounting structure. A shallow face helps clearance, but the bracket, controller and cable still need space.

Output and colour

The readings below refer to the current clear airbag with its named diffusion cloths. They should not be substituted for the older softbox table. Rigid-softbox configurations also have separate published figures.

Choose the diffusion from the required source appearance, then meter at the subject. The labels “1 stop” and “2 stop” identify cloth options; the complete airbag, cloth and grid combination determines the measured output and spread.

CCT	Distance	1-stop (lux)	1-stop + grid (lux)	2-stop (lux)	2-stop + grid (lux)
3,200K	1m	8,070	4,640	6,380	4,390
3,200K	3m	967	797	787	635
5,600K	1m	8,820	5,100	7,020	4,830
5,600K	3m	1,057	876	864	699

Tests and demonstrations

Identify the airbag generation during prep. Compare the published configuration with the actual diffusion, grid, colour and distance before relying on its exposure figure. For matching, look at skin, wardrobe and reflective set materials through the production camera.

Power and batteries

The published maximum consumption for this configuration is 400W. The nominal 400W fixture label and the controller model name do not describe the same electrical quantity.

INFINIMAT controllers can operate supported combinations of mats. Both total capacity and the permitted load at each port matter; the number of sockets is not the number of full-power mats that can always be connected. Use the configuration table for the exact controller.

For battery or other DC operation, confirm the controller version, approved voltage/current, cable and permitted output level. Do not assume a small camera-battery pair can deliver the AC photometric specification. Include the controller’s conversion losses and power limit when estimating runtime.

Control, cooling and camera operation

The control box provides local operation, Sidus app control, wired DMX/RDM, CRMX reception and Ethernet lighting protocols. The mat connects to that controller; it is not an independent Bluetooth fixture.

This size has 4 controllable pixels. Select the matching personality and confirm orientation before programming a moving effect. Keep the pixel map and channel footprint in the lighting notes.

The mat has no local fan assembly like a conventional monolight, but the controller uses cooling fans. Keep the controller ventilated and listen to it at the microphone position. Test low fades and any high-speed camera settings with the installed firmware and the complete cue.

Modifiers, rigging and the working package

Component / accessory	Package considerations
Raised lamp package	The mat, airbag, diffusion and mounting bracket form the raised assembly. Keep the 7.2kg controller accessible and supported separately from the lamp cable.
Controller	400W package; 7.2kg. Position and support it independently of the lamp cable.
Diffusion and spill control	Correct-size clear airbag, 1-stop or 2-stop cloth, skirt and grid.
Head cable	Use the supported cable and connector for this mat/controller class; include cable weight and strain relief in the rig.
Air pump and repair kit	Allow setup access to valves, the specified pump and the supplied patch materials.
Mat-only versus complete kit	An LED & Clear Softbox Pack omits the controller; verify the exact rental or purchase contents.

An inflated airbag is not a structural suspension point unless the manufacturer specifically identifies it as one. Use the approved frame, bracket or rigging points, and protect the airbag from sharp edges.

Leave room to inspect inflation and lower the fixture for service. A large soft surface also catches air movement; weather sealing of the electronics does not remove the mechanical effect of wind.

Alternatives and related fixtures

Fixture	When to compare it
amaran F22c	A smaller full-colour mat package for a lighter travel requirement.
LiteMat Spectrum 4	A rectangular soft-light comparison; include controller, mounting and diffusion.
Nova P600c	A rigid full-colour panel when fast stand mounting is more important than a folding mat.

Rental and used-fixture checks

• Confirm the mat size, controller model and supported port configuration.
• Identify clear-airbag versus older softbox components and match the diffusion and grid.
• Inflate the airbag and inspect valves, seams and contact points before installation.
• Inspect mat backing, mounting hardware, cable strain relief and connectors.
• Test every pixel and the required DMX or wireless-control path.
• Warm the controller, check fan noise and test the intended dimming cue.
• Include all brackets, cables, pumps, patch materials and cases in the order.
