???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 filter 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 AT4053b 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 sourc e such as the Audio-Technica AT8801 single-c hanne l or CP8506 four-channel phantom power supplies.

Out put fro m the mic ropho ne' s XL RM- typ e conn ector 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 positio n reduces the microphone's sensitivity to popping in close vocal use. It also reduces the pickup of low-frequency ambient noise (such as tra ffic, air- handling systems, etc.), room reverberatio n and mechanically coupled vibrations.

The AT4053b consists of two modular subassemblies: an AT4900b-48 body and an AT4053b-EL head capsule (both available separately). Additional interchangeable capsules are available in omnidirectional (AT4049b-EL) and cardioid (AT4051b-EL).

Avoid leaving the microphone in the open sun or in areas where temperatures exceed 110?? F (43?? C) for extended periods. Extremely high humidity should also be avoided.
