BP4002

Omnidirectional Dynamic Microphone

Features

Description

The BP4002 is a dynamic microphone with an omnidirectional polar

pattern. It is designed primarily for on-location interviews.

The output of the microphone is a 3-pin XLRM-type connector.

The microphone is enclosed in a rugged housing. The included AT8470

Quiet-Flex™ stand clamp permits mounting on any microphone

stand with ⅝"-27 threads. A foam windscreen, carrying case and soft

protective pouch are also included.

Operation and Maintenance

Output is low impedance (Lo-Z) balanced. The signal appears across

Pins 2 and 3; Pin 1 is ground (shield). Output phase is “Pin 2 hot”—

positive acoustic pressure produces positive voltage at Pin 2.

To avoid phase cancellation and poor sound, all mic cables must be

wired consistently: Pin 1-to-Pin 1, etc. For a high-impedance (Hi-Z) mic

input, connect a Lo-Z balanced cable to a Hi-Z matching transformer at

the equipment input.

Take care to keep foreign particles from entering the windscreen. An

accumulation of iron or steel filings on the diaphragm, and/or foreign

material in the windscreen’s mesh surface, can degrade performance.

Operation and Maintenance

The microphone shall be a moving coil dynamic designed for handheld

or stand use. It shall have an omnidirectional polar pattern and a

frequency response of 80 Hz to 20,000 Hz. Nominal open-circuit output

voltage shall be 1.5 mV at 1V, 1 Pascal. Output shall be low impedance

balanced (300 ohms).

The output of the microphone shall be a 3-pin XLRM-type connector.

The microphone shall be 240.8 mm long and have a head diameter of

40.0 mm. Weight shall be 276 grams. The microphone shall include a

foam windscreen, stand clamp, carrying case and soft protective pouch.

The Audio-Technica BP4002 is specied.
