Notes on use
ATM75 wired version includes a power module AT8531 that requires 11V to 52V DC
phantom power, or a 1.5V AA battery for operation. A battery need not be in
place for phantom power operation. The output of the power module is a 3-pin
XLRM-type connector.
An integral 80Hz high-pass filter provides easy switching from a flat
frequency response to a low-end roll-off. The roll-off position reduces the
pickup of low-frequency ambient noise (such as traffic, air-handling systems,
etc.), room reverberation and mechanically coupled vibrations.
ATM75cW and ATM75cH wireless versions do not contain power module and includes
clothing clip and metal-frame pop filter only. 1.4 m cable terminated with
locking 4-pin connector. The connector is also compatible with Audio-Technica
cW and cH type body-pack transmitters.
Avoid leaving the microphone in the open sun or in areas where temperatures
exceed 43°C for extended periods. Extremely high humidity should also be
avoided.
