The Power Grid & XLR Audio Box with Dual LP-E6 Plates for Blackmagic Pocket Cinema Camera provides power to your Blackmagic Pocket Cinema Camera using two available Canon LP-E6 type batteries (not included) and converts two XLR inputs to a 3.5mm stereo audio output to provide two channels of audio directly to your camera. The Power Grid System incorporates a clamp so you can mount it to LWS 15mm support rods and it features a right angle power plug to keep the cable neat and snug on the camera. The Power Grid 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 into 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 for 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.
