Robe Tetra2 Intruduction a powerful linear bar with 4°-45° zoom

Here today we would like to introduce one powerful linear bar with 4°-45° zoom from ROBE-Tetra2.

TETRAgnatha’s are linear bars, built on the highly successful Spiider and Tarrantula technology. TETRA2™ is the larger format of the TETRAgnatha duo.

Generating an ultra-tight 4° 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 as the detailed design allows any combination of TETRA1™ and TETRA2™ to be placed end to end on stage or truss, whilst maintaining equal spacing between pixels. With the addition of two exclusive Robe patented MCFE™ – Multi-Coloured Flower Effects, the pixel-driven Tetra1 sets itself apart from others by projecting charismatic in- air animations.

The homogenised beams, together with the smooth 11:1 zoom, provide; a wash out to 45°, a footlight, a wall graze or dynamic in-air effects with fast paced sweeping movements. Utilizing our latest L3™ (Low Light Linearity) dimming system for an imperceptible fade to black, the 18-bit control provides ultra-smooth colour mixing across the full colour spectrum. 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.
