Audio-Technica U.S., Inc. Lavalier/Instrument Microphone PRO 70

This miniature condenser microphone achieves full-sounding pickup and is known for outstanding consistency and dependable performance. Supplied with both a clothing clip and guitar mount, it provides natural and articulate vocal reproduction when used as a clip-on lavalier and excels in pickup of acoustic guitar. The PRO 70 is designed to make music and speech clearly and comfortably audible, yet never draw attention to itself or its operation. The microphone is equipped with a low-frequency roll-off switch that allows for reduced pickup of room noise. The versatile PRO 70 may be powered by either battery or phantom power. Its cardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of the desired sound source.
