Audio-Technica AT2050 LEX780034 Dépliant
Codici prodotto
LEX780034
• Three switchable polar patterns: omni, cardioid, figure-of-eight
• Dual-diaphragm capsule design maintains precise polar pattern
definition across the full frequency range of the microphone
• Switchable 80 Hz high-pass filter and 10 dB pad
• State-of-the-art surface-mount electronics ensure compliance with
A-T's stringent consistency and reliability standards
• Dual large diaphragms are gold-vaporized and aged to achieve
optimum characteristics over years of use
The AT2050 is intended for use in professional applications where
remote power is available. It requires 11V to 52V 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 traffic, air-handling systems, etc.), room reverberation and
mechanically-coupled vibrations.

In use, secure the cable to the mic stand or boom, leaving a slack
loop at the mic. This will ensure the most effective shock isolation
and reduce the possibility of accidentally pulling the microphone out
of its mount.

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.
