The Energy Transformation Systems PA911 Audio Camera Balun is an 18" (45.72cm) long XLR-female to 1/8" (3.5mm)-male cable, that enables professional microphones to be connected to the Canon 5D and 7D DSLR cameras. Energy Transformation Systems' experience in balun technology results in an audio cable that maintains a low-noise, balanced signal for up to 2000' (609m) in range. The PA911 cable accepts dynamic microphones, as well as signals from condenser microphones, providing their own phantom power via battery or power supply (cameras and PA911 do not supply phantom).
