TETRAgnatha is a Linear bar building on the Spiider and Tarrantula technology.

Generating an ultra-tight 4.5° beam from each of the 18 pixels, they combine to produce a bright, defined "sheet" of light, desired by Lighting Designers. Seamless curtains of light can be constructed using several fixtures.

With the addition of two exclusive Robe patented  MCFE™ – Multi-Coloured Flower Effects, the pixel-driven Tetra sets itself apart from others by projecting charismatic in-air animations.

The compact, detailed design, allows end to end placement on stage or truss, maintaining equal spacing between pixels. The homogenised beams, together with the smooth 10:1 zoom, provide; a wash out to 45°, a footlight, a wall graze or dynamic in-air effects with fast paced sweeping movements.

Utilizing the latest Robe proprietary technology, including; L3™ - (Low Light Linearity) for an imperceptible fade to black, 18 bit control for ultra-smooth colour mixing and Cpulse™ for flicker free film and television - including the very latest cameras.

An embedded Ethernet switch and wide range of protocols (sACN, Art-Net or Kling-Net) allow a quick network installation and ease of control from media servers, DMX or the internal effects engine.
