Audio-Technica Pro 70 Cardioid Lavalier Microphone Cardioid condenser lavalier/instrument microphone The Audio-Technica Pro 70 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. Accurate Vocal and Acoustic Guitar Reproduction The tailored frequency response favors the mid-range frequency response associated with vocal intelligibility and presence. Cardioid Polar Pattern The cardioid pattern is effective in signal isolation. Audio signal at the off-axis sections of the capsule are attenuated, minimizing noise and improving gain-before-feedback response. Low Frequency Roll-Off A low frequency roll-off filter switch minimizes low frequency noise and rumble due to wind, hum and proximity effect.
