Audio Technica U891RCX Push to Talk Boundary Condenser Microphone

<p>Designed to deliver easy, flexible control in conference and boardroom installations, the versatile U891R cardioid condenser boundary microphone features a touch-sensitive on-off switch that can be set to three modes: press-on/press-off, press to talk, and press to mute. The phantom-powered microphone is equipped with a unique PivotPoint™ rotating output connector and an LED status indicator. UniGuard™ innovations offer unsurpassed immunity from radio frequency interference; interchangeable elements are available in cardioid, hypercardioid and omnidirectional polar patterns; an 80 Hz low-cut UniSteep® filter reduces pickup of low-frequency ambient noise. The microphone’s heavy die-cast case and silicon foam bottom pads minimize coupling of surface vibration to the microphone. The unit’s self-contained electronics eliminate the need for an external power module.</p><p>* Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations<br />* Ultra-quiet electronic switch can be set to any of three operating modes: “touch-on/ touch-off,” “touch-to-talk” and “touch-to-mute”<br />* PivotPoint™ rotating output connector allows cable to exit from either the rear or the bottom of the microphone<br />* Superior off-axis rejection for maximum gain before feedback<br />* UniGuard™ RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)<br />* Small-diameter UniPoint capsule near boundary eliminates phase distortion and delivers clear, high-output performance<br />* Heavy die-cast case and non-slip silicon foam bottom pads minimize coupling of surface vibration to the microphone<br />* Low-profile design with low-reflectance finish for minimum visibility<br />* Available in two colors: black (U891R) and white (U891RW)<br /><br /><b>SPECIFICATIONS: </b></p><ul> <li>ELEMENT Fixed-charge back plate, permanently polarized condenser</li> <li>POLAR PATTERN Half-cardioid</li> <li>(cardioid in hemisphere above mounting surface)</li> <li>FREQUENCY RESPONSE 30-20,000 Hz</li> <li>LOW FREQUENCY ROLL-OFF 80 Hz, 18 dB/octave</li> <li>OPEN CIRCUIT SENSITIVITY –34 dB (19.9 mV) re 1V at 1 Pa</li> <li>IMPEDANCE 200 ohms</li> <li>MAXIMUM INPUT SOUND LEVEL 130 dB SPL, 1 kHz at 1% T.H.D.</li> <li>DYNAMIC RANGE (typical) 104 dB, 1 kHz at Max SPL</li> <li>SIGNAL-TO-NOISE RATIO 68 dB, 1 kHz at 1 Pa</li> <li>PHANTOM POWER REQUIREMENTS 11-52V DC, 4 mA typical</li> <li>SWITCHES Touch-sensitive control: on/off;</li> <li>Switch function: touch on/off, momentary on, momentary off;</li> <li>Flat, roll-off</li> <li>WEIGHT 9.3 oz (264 g)</li> <li>DIMENSIONS 4.25" (108.0 mm) long,</li> <li>3.31" (84.0 mm) maximum width,</li> <li>0.91" (23.0 mm) height</li> <li>OUTPUT CONNECTOR TB3M-type</li> <li>CABLE 25.0 (7.6 m) long, 0.13" (3.2 mm) diameter, 2-conductor, shielded cable with TA3F and XLRM-type connectors</li> <li>OPTIONAL INTERCHANGEABLE ELEMENTS UE-H hypercardioid (100°);</li> <li>UE-O omnidirectional (360°)</li> <li>ACCESSORY FURNISHED Soft protective pouch</li></ul>
