Phantom power operation (K6 and K6P) Both the K6 and K6P powering modules can be powered by 12-48V DC phantom power via the connection cable (phantom powering). Roll-off filter The bass roll-off filter (B) (see drawing on previous page) effectively rejects rumble, handling, pop and wind noises, as well as reducing the proximity effect when used in close miking situations. * Resultant length: this is the figure you need to add to the capsule length to give the overall length of the complete microphone.
