The Rode NT45-C is an interchangeable cardioid microphone capsule to suit the RODE NT4, NT5, NT55 or NT6 microphones. The Cardioid pattern is ideal for directional audio pickup, while rejecting most back ground noise. Ideal for live and group recording when you want to pick-up 1 audio source. Super easy to fit, simply unscrew the existing capsule and screw on the new NT45-C. Supplied in a padded tin for protection during storage and transport.
