Description
The AT8022 is a fixed-charge condenser microphone with an X/Y stereo polar pattern. It is designed for broadcast, recording and field use. The microphone requires 11V to 52V phantom power or a 1.5V AA battery for operation. A battery need not be in place for phantom power operation. The microphone offers an innovative coincident capsule configuration. This allows for a smaller housing while producing an X/Y stereo image with the spatial impact and realism of a live sound field.
The microphone includes two cables: a 2 m (6.5') balanced cable terminating in a 5-pin XLRF-type and two 3-pin XLRM-type connectors; a 0.6 m (2') unbalanced cable terminating in a 5-pin XLRF-type and a 3.5 mm TRS connectors. The output of the microphone is a 5-pin XLRM-type connector. A switch permits choice of flat response or low-frequency roll-off (via integral 80 Hz high-pass filter) to help control undesired ambient noise.
The microphone is enclosed in a rugged housing. The included AT8405a stand clamp permits mounting on any microphone stand with 5/8"-27 threads. A windscreen, a battery and a soft protective pouch are also included.
