BP892 & BP892-TH

The donut-shaped moisture guard is provided to protect the element from sweat and moisture. Position the moisture guard as close to the element as possible to provide maximum protection. To remove the moisture guard, first remove the element cover and place it out of harm’s way. Gently slide the moisture guard over the element. Replace the element cover.

Avoid leaving the microphone in the open sun or in areas where temperatures exceed 110° F (43° C) for extended periods. Extremely high humidity should also be avoided.

Architect’s and Engineer’s Specifications

The microphone shall be a fixed-charge condenser designed for headworn use. It shall have an omnidirectional polar pattern and a frequency response of 20 Hz to 20,000 Hz. The microphone shall operate from an external 11V to 52V DC phantom power source. It shall be capable of handling sound input levels up to 135 dB with a dynamic range of 104 dB. Nominal open- circuit output voltage shall be 3.5 mV at 1V, 1 Pascal. Output shall be low impedance balanced (250 ohms). The microphone shall be RoHS compliant.

The microphone shall have a 1.4 m (55") permanently attached miniature cable terminating in a locking 4-pin output connector. The output connector shall connect to a jack on the included power module. The output connector shall also connect to any Audio-Technica UniPak® body-pack wireless transmitter. The power module shall contain a recessed switch to permit choice of flat response or 80 Hz low-frequency roll-off. The output of the power module shall be a 3-pin XLRM-type connector.
