Audio-Technica Professional PRO70 Cardioid Lavalier Microphone SKU# PRO70

The Audio-Technica PRO70 is a cardioid lavalier microphone designed for vocal or instrument capturing in recording or sound reinforcement applications. The frequency response favors the mid-range frequencies of instruments and vocals while minimizing noise registering at high and low frequencies.

The cardioid polar pattern is effective in minimizing pickup at the off-axis sections of the microphone capsule. The result is improved signal before feedback response and minimal ambiance pickup. A low frequency roll-off switch further reduces low frequency noise due to hum, wind etc. The provided UM3 power supply provides phantom power with a single 1.5V AA battery or external phantom power source. The UM3 provides a standard 3-pin XLR output connection to mixers, preamplifiers, cameras etc.
