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 microphones 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 compliantfree 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.
