The AT8024 also comes equipped with a three-position adjustable input pad (-20 dB, -10 dB, 0 dB) to capture even soft and very loud sound passages without distortion. A switchable low-frequency roll-off reduces pickup of undesired ambient noise, room reverberation and mechanically coupled vibrations. The microphone is powered by a single AA battery for optimal performance with high max SPL, and features an integral camera shoe mount that attaches quickly to DSLRs and shoe-equipped camcorders.
