Audio-Technica AT4053b - Manual

• 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

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
a s t ra f f i c, a i r - h a n d l i n g s y s t e m s, e t c . ) , r o o m r eve r b e ra t i o n a n d
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.
