VL2C Luminaire Sound Baffle and Sound Blanket
The original VL2C sound baffle was modified from a rectangle to a truncated rectangle so that the luminaire will fit on
a stage truss with little interference to other equipment. In addition, a sound blanket was designed to fit over the
luminaire upper enclosure and sound baffle to provide additional sound isolation. It is a two piece plastic shell with an
inner foam lining and attaches to the luminaire with two side buckles and three nylon straps with buckles. The sound
blanket can only be used with the truncated rectangle sound baffle. The older style rectangular sound baffle can still
be used without the sound blanket. Kits are available to convert rectangular sound baffles to truncated sound baffles.
The modified sound baffle and sound blanket were designed primarily for the VL2C luminaire’s louder cooling fan.
