The AT2050 is a large-diaphragm side-address externally polarized (DC bias) condenser microphone with three switchable polar patterns:omnidirectional, cardioid, and figure-of-eight. It is designed for home/project/professional studio applications and live performance. The microphone requires 11V to 52V phantom power for operation. The omnidirectional polar pattern is sensitive to sound coming from all directions. Select the omni pattern to pick up several voices or instruments on the same microphone, to diminish proximity effect, and to preserve the location's ambient sound. The cardioid polar pattern is more sensitive to sound originating directly in front of the element, making it useful in controlling feedback, reducing pickup of unwanted sounds and providing isolation between performers. The figure-of-eight polar pattern is more sensitive to sound originating in the front and back of the microphone, rejecting sounds from the sides. It is often used in conjunction with advanced stereo miking techniques. The output of the microphone is a 3-pin XLRM-type connector. The microphone is equipped with a switchable 10 dB pad and a switch that permits choice of flat response or low-frequency roll-off (via integral 80 Hz high-pass filter). The microphone is enclosed in a rugged housing. The included AT8458 shock mount provides superior isolation and permits mounting on anymicrophone stand with 5/8"-27 threads. A soft protective pouch is also included.
Operation and Maintenance
The AT2050 requires 11V to 52V phantom power for operation. Output is low impedance (Lo-Z) balanced. The signal appears across Pins2 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 Audio-Technica emblem and the pattern-selection switch are on the front of the microphone. Position this side of the microphone toward the sound source. The pattern-selection switch provides user-selection of omnidirectional, cardioid, and figure-of-eight polar patterns. To select the omnidirectional polar pattern, slide the switch to the circular polar pattern image. To select the cardioid polar pattern, slide the switch to the heart-shaped polar pattern image. To select the figure-of-eight pattern, slide the switch to the figure-eight shaped polar pattern image. An integral 80 Hz high-pass filter provides easy switching from a flatfrequency response to a low-end roll-off. The roll-off position reduces the microphone's sensitivity to popping in close vocal use. It also reducesthe pickup of low-frequency ambient noise (such as traffic, air-handling systems, etc.), room reverberation and mechanically coupled vibrations.To engage the high-pass filter, slide the switch toward the "bent" line. The microphone is also equipped with a switchable 10 dB pad that lowersthe microphone's sensitivity, thus providing higher SPL capability for flexible use with a wide range of users and system configurations. Toengage the 10 dB pad, slide the switch toward the -10 position. In use, secure the cable to the mic stand or boom, leaving a slack loop atthe 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 highhumidity should also be avoided.
