Product Description

The U891RCx is a wide-range condenser microphone with a cardioid polar pattern. It is designed for surface-mount applications such as high-quality sound reinforcement, conferencing, distance learning and other demanding sound pickup applications.

The microphone features an activation switch, a programmable external contact closure and an LED indicator. The activation switch can be set to any of three operating modes: “press-on/press-off,” “press-to-talk” and “press-to-mute.” The microphone’s external contact closure capability permits control of remote devices. The contact closure can also be configured to operate independently of the microphone element for applications that require a constant signal from the microphone element. A switch on the bottom of the microphone allows selection of local or remote operation. (In remote operation, the LED and activation switch operate independently of the microphone.) A third position on this switch enables the LED to be controlled from an external source.

The microphone requires 11V to 52V phantom power for operation. The microphone is equipped with UniGuard RFI-shielding technology, which offers outstanding rejection of radio frequency interference (RFI). The microphone’s cardioid polar pattern provides a 120° angle of acceptance (cardioid in hemisphere above mounting surface). Additional interchangeable elements with omnidirectional (360°) and hypercardioid (100°) pickup patterns are available(Can be ordered separately).

The microphone includes a 7.6 m (25') output cable terminating in a special TA5F-type connector at the microphone end. The equipment end is stripped and tinned for connection to an electronic device. The microphone is equipped with Audio-Technica’s unique PivotPoint rotating output connector.

A switch permits choice of flat response or low-frequency roll-off (via integral 80 Hz high-pass UniSteep filter) to help control undesired ambient noise.

The microphone’s heavy die-cast case and non-slip silicone foam bottom pads minimize coupling of surface vibration to the microphone. The microphone includes a soft protective pouch and features a low-reflectance Black finish.

Features
