Product Information
Audio-Technica's ATM75cH is a cardioid condenser headworn microphone engineered for hands-free vocal capture in professional live and broadcast applications. The permanently polarised fixed-charge back plate condenser element delivers a 100–13,000 Hz frequency response optimised for speech and vocals. Available in three cable configurations, the cH variant terminates in a screw-down 4-pin connector compatible with Audio-Technica's cH-style body-pack wireless transmitters, making it a natural fit for touring performers and live sound rigs already invested in that ecosystem.
The flexible boom pivots left or right, positioning the 20.4 mm microphone head away from sightlines whilst the low-visibility headband maintains stable, comfortable fit throughout extended performances. Maximum SPL ratings reach 132 dB under phantom power or 121 dB on battery, with a 96 dB dynamic range and 58 dB signal-to-noise ratio at 1 Pa. The cardioid polar pattern isolates the desired vocal source whilst rejecting off-axis noise. Supplied accessories include both large (AT8139L) and small (AT8139S) windscreens, a clothing clip, and a 1.4 metre permanently attached shielded cable.
The wired battery-powered configuration (1.5V AA) provides 2000 hours of typical runtime at 0.4 mA draw, useful for venues without phantom power infrastructure. A low-frequency roll-off switch at 80 Hz, 18 dB/octave helps suppress rumble and handling noise during stage movement. Total microphone weight is just 60 grams, minimising headband fatigue during multi-hour sets.
