The Power Grid & XLR Audio Box with Dual LP-E6 Plates for Blackmagic Cinema/4K Production Cameras powers your Blackmagic Cinema Camera or 4K Production Camera using two available Canon LP-E6 type batteries, and converts two XLR inputs to 1/4″ TRS plugs that connect with your camera’s audio inputs. The Plate incorporates a clamp so you can mount it to LWS 15mm support rods. The plate itself features a two-sided design that mounts the batteries one on each face, two batteries are required to supply the necessary voltage to power the camera. The batteries securely snap in to the plate, and you must press a small tab to remove them. A blue LED built into the plate lights up to indicate sufficient voltage to power the camera. When used in conjunction with the camera’s internal battery, you can hot swap the batteries without powering down the camera. Made in the USA.
