Audio Technica ES945 Omnidirectional fixed charge condenser boundary microphone

The new Engineered Sound.

This low-profile omnidirectional condenser boundary microphone is designed for clear, highly intelligible sound reinforcement, professional recording and teleconferencing in table-, ceiling-, or panel-mount applications. The microphone is equipped with a self-contained power module with an XLRM-type output connector, eliminating the need for an external power module. The microphone offers unsurpassed immunity from radio frequency interference thanks to Audio-Technica's UniGuard® innovations. Protected by a rugged all-metal case with a two-layer steel mesh grille, the microphone has a 360º pickup angle, and is available in two colors: black (ES945) and white (ES945W).

Designed to deliver easy, flexible control in conference and boardroom installations, the versatile U891Rx 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.

With three cardioid condenser elements in a single housing, the phantom-powered U843R offers a remarkably versatile tool for surface-mount installations. Levers on the microphone base allow easy reorientation of two elements to offer 360° or 300° coverage. Since elements can be powered and used individually or in any combination, further flexibility is easily achieved. For example, with two elements powered, the microphone can provide a figure-of-eight polar pattern; with a single element powered, the microphone functions as a standard cardioid boundary microphone. Installation and repositioning are extremely quick, thanks to four recessed pathways on the base of the microphone that enable the user to route the cable as required to accommodate any installation requirements; no tools or disassembly are needed. The microphone also offers Audio-Technicaʼs innovative UniGuard® RFI-shielding technology.

C 562 CM 

Small, low-profile boundary layer microphone
Wide frequency range
High sensitivity
Ideal for inconspicuous installation in a room
Suited for surveillance or recording
 
The C 562 CM flush-mount boundary microphone uses the same transducer as the C 562 BL.
The C 562 CM has been designed specifically for permanent, "invisible" mounting in ceilings,
walls, tables, stage props, etc.
Owing to its high sensitivity, the C 562 CM is a perfect tool for surveillance or live recording
since a single microphone can cover an entire room. The supplied XLR phantom power adapter
connects to the microphone cable through a miniature connector so installation holes can be
smaller than the diameter of the phantom power adapter.
