Descriptions
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.
 
Features
• 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.
