Audio-Technica''s Line and Gradient Condenser Microphones combine a directional capsule (gradient) and an interference tube which removes the sound from the rear. Generally, the interference tube of this type of microphone can be extended to reduce the acceptance angle and thus increase the sound capture distance. Short condenser microphones do not have as long a range as shotgun models, but in some cases are preferred for their greater acceptance angle, when the accuracy of the source is less important. Features 369mm Shotgun Microphone, designed for video production and broadcast (ENG/EFP) audio acquisition Provides the narrow acceptance angle desirable for long-distance sound pickup Captures sound with high intelligibility in noisy environments with its excellent sound rejection from the sides and rear of mic Two power modes (battery or phantom power) for versatility 80Hz low-frequency roll-off, with a slope of 18dB / octave to reduce pickup of low-frequency ambient noise Effective protection against interference from nearby mobile phones and other unwanted radio frequencies Equipped with a foam windscreen, the AT8035 comes with a 1.5V AA battery, a stand clamp and a carry case Specifications Element: Fixed-charge back plate, permanently polarized condenser Polar Pattern: Line + gradient Frequency Response: 40-20,000 Hz Open Circuit Sensitivity: Phantom: -38 dB (12.5 mV) re 1V at 1 Pa Battery: -39 dB (11.2 mV) re 1V at 1 Pa Impedance: Phantom: 250 ohms Battery: 300 ohms Maximum Input Sound Level: Phantom: 132 dB SPL, 1 kHz at 1% T.H.D.
