The Audio-Technica ES905CL is a professional cardioid condenser gooseneck microphone designed for sound reinforcement, broadcasting, and recording applications. Featuring a fixed-charge back plate permanently polarized condenser element, it delivers a uniform cardioid polar pattern with 120° acceptance angle. Frequency response ranges from 60 Hz to 20 kHz with an 80 Hz low-cut UniSteep® filter (18 dB/octave) to reduce low-frequency ambient noise. The rigid-pipe construction with ball-in-socket base allows flexible positioning, while the metal base mounts securely to tables, desks, or podiums. Requiring 11-52V DC phantom power, the microphone provides superior off-axis rejection and features UniGuard® RFI-shielding technology. Dimensions: 523.4 mm long with 24.6 mm head diameter.
