Frequency response Low cut High frequency boost Out-of-axis frequency response Directional pattern Cardioid Super-cardioid Effective pick-up angle (3dB sensitivity decreasing) cardioid 1300, super-cardioid 300 -400 Sensitivity Dynamic range Sennheiser MKH 416 Power Supply: P or T Sennheiser MKH 60 Sennheiser MKH 70 Sennheiser MKH 416 vs. 60 vs. 70 Sanken CS-1 Short shotgun Very sharp directivity in a 181.5mm length body Flat frequency response beyond 20kHz(on axis) High sensitivity -30dB/Pa Accepts high SPLs. More than 137dB SPL (1% THD). With no distortion in close miking. Narrow angle directivity over the entire frequency range. Overrall rear rejection. 22dB/20kHz. 18dB/10kHz. 27dB/1kHz. 27dB/200Hz. Light weight. Only 100g. Easy to operate on a boom pole. Schoeps CMIT 5 U Low coloration of off-axis sound Even greater immunity to wind noise than a SCHOEPS super-cardioid Directionality increases smoothly with higher frequencies, which results in a very balanced sonic character Capsule and amplifier are built as a single unit Schoeps CMIT 5 U _more The sound quality of the CMIT 5 remains consistent even if t
