Overview

ES933

The ES933 condenser hanging microphone is designed for quality sound reinforcement, professional recording, television, and other demanding sound pickup applications. Its low-profile design and excellent response make it ideally suited for suspending over choirs, instrumental groups and theater stages.

The microphone is equipped with a 15.2 m (50') permanently attached miniature cable, terminated with a TA3F-type connector that attaches to compatible Audio-Technica power modules. UniGuard® RFI-shielding technology protects the microphone from radio frequency interference (RFI).

The microphone comes with a two-stage foam windscreen and vinyl-coated steel hanger. Additional interchangeable elements – omnidirectional (360°), cardioid (120°), hypercardioid (100°), and MicroLine® (90°) – are available separately.

Available configurations:

ES933C/MIC: cardioid polar pattern (120° acceptance angle); no power module; low-reflectance black finish.

ES933H/MIC: hypercardioid polar pattern (100° acceptance angle); no power module; low-reflectance black finish.
