It shall be capable of handling sound input levels up to 135 dB with a dynamic range of 115 dB. Nominal open-circuit output voltage shall be 17.7 mV at 1 V, 1 Pascal. Output shall be low impedance balanced (250 ohms). It shall offer outstanding rejection of radio frequency interference (RFI).

The microphone shall have a permanently attached 7.6 m (25') miniature cable terminating in a special TA3F-type output connector designed

to optimize RFI immunity. The output connector shall connect to a TB3M-type jack on the included power module. The power module shall contain a recessed switch to permit choice of flat response or 80 Hz low-frequency roll-off. The output of the power module shall be a 3-pin XLRM-type connector.

An adjustable steel wire hanger shall be provided for suspended installations. The steel wire hanger shall attach to the microphone body and allow for the positioning of the microphone without the need for tools. A two-stage foam windscreen and a 5/8"-27 stand adapter shall also be included.

The microphone shall be a hanging design, with an overall length of 156.0

mm(6.14") and a head diameter of 12.2 mm (0.48"). Weight shall be 30 grams (1.1 oz) without cable. The microphone, cable and steel hanger shall be black [white].

Audio-Technica U853RWU, U853RU manual Architect’s and Engineer’s Specifications

U853RU, U853RWU specifications

Audio-Technica is a name synonymous with high-quality audio equipment, and its U853RWU and U853RU models exemplify this commitment to excellence in sound reproduction. Designed primarily for professional applications, these condenser microphones are ideal for podiums, presentations, and theater performances, offering superior performance and versatility.

The Audio-Technica U853RWU is a boundary microphone that excels in capturing clear and natural sound. One of its standout features is the half-cardioid polar pattern, which effectively isolates sound sources while minimizing background noise. This feature is particularly beneficial in environments where multiple speakers are present, ensuring that the microphone captures only the desired audio.

Another significant aspect of the U853RWU is its innovative design, which incorporates a low-profile enclosure. This allows for discreet placement, making it an excellent choice for aesthetic-sensitive settings such as conference rooms and auditorium stages. Additionally, the U853RWU offers a wide frequency response range of 30 Hz to 20 kHz, providing exceptional detail and clarity across the audio spectrum.

Similarly, the U853RU model shares many features with the U853RWU but is tailored for different applications. It also boasts high sensitivity and low self-noise, making it suitable for capturing nuanced vocal performances and instrument sounds. Both microphones are equipped with a robust construction designed to endure the rigors of stage use, ensuring longevity.

Audio-Technica employs advanced technologies in the U853RWU and U853RU, including a high-quality internal acoustic windscreen that minimizes popping sounds from plosives, further enhancing audio clarity. The frequency response can be tailored using optional accessories, allowing users to customize the mic's performance to better suit specific needs.

In summary, the Audio-Technica U853RWU and U853RU are powerful tools for audio professionals seeking reliability and high-fidelity sound. With features like half-cardioid polar patterns, wide frequency response, and durable construction, these microphones are designed to meet the demands of both live performances and studio recordings. Whether used in corporate environments or artistic venues, these models are primed to deliver exceptional audio quality.
