OMNIDIRECTIONAL 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 AT4049b 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 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 traffic, air-handling systems, etc.), room reverberation and
mechanically coupled vibrations.
The AT4049b consists of two modular subassemblies: an
AT4900b-48 body and an AT4049b-EL head capsule (both available
separately). Additional interchangeable capsules are available in
cardioid (AT4051b-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.
