11V to 52V DC phantom power source. It shall be capable of handling
sound input levels up to 130 dB with a dynamic range of 104 dB. Nominal
open circuit output voltage shall be 19.9 mV at 1 V, 1 Pascal. Output
shall be low impedance balanced (200 ohms). It shall offer outstanding
rejection of radio frequency interference (RFI).
The microphone shall be equipped with an activation switch that can be
set to any of three operating modes: “press-on/press-off,” “press-to-talk”
and “press-to-mute”.
The microphone shall incorporate self-contained electronics, eliminating
the need for an external power module. A 7.6 m (25') miniature output
cable with TA3F-type to XLRM-type connectors shall be supplied.
The output of the microphone shall be a TB3M-type connector. The
microphone shall include a switch to permit choice of at response or 80
Hz low-frequency roll-off.
The microphone shall be equipped with an integral rotating output
connector that allows the cable to exit from either the rear or the bottom
of the microphone without the need to disassemble the microphone or
use tools to change the cable exit location.
The microphone shall have a maximum width of 84.0 mm (3.31"), a
maximum length of 108.0 mm (4.25") and a maximum height of 23.0
mm (0.91"). Weight shall be 264 grams (9.3 oz). The microphone shall
be housed in a die-cast case with a perforated steel grille. Finish shall
be low-reectance black [white]. The microphone shall include a soft
protective pouch.
The Audio-Technica U891Rx [U891RWx] is specied.
In the interest of standards development, A.T.U.S. offers full
details on its test methods to other industry
professionals on request.
