CARDIOID CONDENSER MICROPHONE
- Specially engineered to meet the most critical acoustic requirements of
professional recording, broadcast and sound reinforcement
- Direct-coupled, balanced output results in a clean signal even under
high-output conditions
- Transformerless circuitry virtually eliminates low-frequency distortion and
provides superior correlation of high-speed transients
- Switchable 80 Hz hi-pass lter and 10 dB pad
- Rugged turned-brass microphone housing for enduring dependability
- State-of-the-art design and manufacturing techniques ensure
compliance with A-T’s stringent consistency and reliability standards.
The AT4051b 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 CP8506 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 high-pass 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 AT4051b consists of two modular subassemblies: an AT4900b-48
body and an AT4051b-EL head capsule (both available separately).
Additional interchangeable capsules are available in omnidirectional
(AT4049b-EL) and hypercardioid (AT4053b-EL).
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.
