Audio-Technica Debuts Hand-Built AT5045 Cardioid Condenser Microphone at AES2014


AT5045Leeds, UK, 09-10-2014: Audio-Technica is to unveil the latest addition to its flagship 50 Series studio microphone range at the AES Convention in Los Angeles on October 10. The AT5045 is a hand-built, large-diaphragm, stick-design side-address condenser instrument microphone with a cardioid polar pattern designed to deliver natural, well-balanced sound with exceptional realism and depth. Available separately or as stereo pairs (AT5045P), the mics are engineered to meet the most critical requirements of professional recording.

The AT5045’s large diaphragm design allows for fast transient response, low noise, high SPL handling (149 dB SPL) and impressive dynamic range (141 dB). Such specifications make it an ideal instrument microphone, particularly suited to use on overheads, percussion, acoustic guitar, strings and other acoustic instruments requiring the capture of dynamic, detailed sound.

Featuring a proprietary breakthrough in element design, the AT5045 employs a large rectangular element, crafted by Audio-Technica engineers to improve transient response and increase response bandwidth. Discrete components were carefully selected for the AT5045 to maximise performance and its two-micron-thick, vapour-deposited gold diaphragm has been aged to achieve optimum sonic characteristics that will remain constant over years of use.

Another key AT5045 design feature is its advanced internal shock mounting, which effectively decouples the capsule from the microphone body. For additional isolation, the AT5045 comes with an innovative isolation clamp, engineered not only to isolate the microphone but also to provide versatile positioning while offering effective damping of mechanical noise and resonances that could be transmitted to the microphone. The cardioid polar pattern of the microphone is more sensitive to sound originating directly in front of the element, making it effective in reducing pickup of unwanted sounds and providing isolation of the instrument.

The AT5045 is enclosed in an elegant, rugged aluminium and brass housing, which also allows it to be used for live-sound applications. The included AT8481 isolation clamp permits mounting on any microphone stand with ⅝” threads. An AT8165 windscreen and custom hard-shell carrying case are also included.
