2002, Shure Incorporated MODEL MX183, MX184, MX185 MICROPHONES OVERVIEW Models MX183, MX184, and MX185 are wired lavalier electret condenser microphones designed for speech and vocal pickup, general purpose sound reinforcement, record- ing, and remote monitoring applications. They can be clipped to neckties, lapels, and other articles of clothing. Interchange- able cartridges make it possible to easily reconfigure micro- phone coverage as the need arises. FEATURES  Wide dynamic range and frequency response for accurate sound reproduction across the audio spectrum  Interchangeable cartridges that provide an optimal choice for each application  Rotatable tie-clip that pivots in 90 increments for place- ment flexibility  Supplied snap-fit foam windscreen that controls breath noise and stays on securely  Balanced, transformerless output for increased immunity to noise over long cable runs  Supplied dual tie clip holds two microphones for dual miking applications MODEL VARIATIONS MX183 (Omnidirectional): Provides low handling noise. Pickup angle = 360°. MX184 (Supercardioid): Provides high rejection of ambi- ent noise and narrow pickup angle. Use of windscreen highly recommended. Pickup angle (–3 dB) = 115°. MX185 (Cardioid): Provides good rejection of ambient noise. Use of windscreen highly recommended. Pickup angle (–3 dB) = 130°.
