Architect’s and Engineer’s Specifications
The microphone shall be a fixed-charge condenser designed for
permanent installation or portable applications. It shall have a UniLine
®
(line cardioid) polar pattern with a uniform 90° angle of acceptance
and a frequency response of 30 Hz to 20,000 Hz. It shall be capable of
accepting optional interchangeable elements for additional polar patterns.
The microphone shall operate from an external 11V to 52V DC phantom
power source. 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].
The Audio-Technica U853RU [U853RWU] is specified.
