LINE + GRADIENT CONDENSER MICROPHONE

- Overall length of 539mm with an extremely narrow, highly directional

pickup pattern

- Designed for use in broadcasting, lm/TV production, and theater

sound reinforcement applications

- Direct-coupled, balanced output ensures a clean signal even in

high-output conditions

- Transformerless design for improved pickup of transients

- Rugged housing made of lightweight structural-grade aluminum

alloy

- Interference tube design for narrow acceptance angle

- Transformerless design for improved pickup of transients

- Switchable 80 Hz high-pass lter & 10 dB pad

The BP4071L is intended for use in professional applications where

remote power is available. It requires 48V DC phantom power, which

may be provided by a mixer or console, or by a separate, in-line

source such as the Audio-Technica AT8801 single-channel or AT8506

four-channel phantom power supplies.

Output from the microphone’s XLRM-type connector 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.

An integral 80 Hz hi-pass filter provides easy switching from a flat

frequency response to a low-end roll-off. The roll-off position reduces

the microphone's sensitivity to popping in close vocal use. It also

reduces the pickup of low-frequency ambient noise (such as trafc,

air-handling systems, etc.), room reverberation and mechanically-

coupled vibrations.

The BP4071L is also equipped with a switchable 10 dB pad that

lowers the microphone's sensitivity, thus providing higher SPL

capability for flexible use for a wide range of speakers/performers

and system congurations.

The microphone is RoHS compliant–free from all substances

specied in the EU directive on hazardous substances.

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.
