ES945 Omnidirectional Condenser Boundary Microphone
The new Engineered Sound. Contractor-exclusive innovations for every acoustical challenge. And safe haven from RFI.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 360° pickup angle, and is available in two colors: black (ES945) and white (ES945W).

Answer:Â
Thank you for your inquiry. You did not mention the height of the ceiling and if the participants would be seated or standing. I will assume a ceiling of 8 feet and participants seated. If this is the case, placing the microphones 10.3 feet apart from each other should be sufficient.Age:Â 45-54

it's written in the specification that it is 3 pin connector.
2 pin are differential signal ouptut, tird one is the ground.
then is there any battery inside? or another power plug that I dont see?

Answer:Â
Phantom power is DC voltage sent down the microphone cable to power the preamplifier of a condenser mic capsule - sometimes through a power module. The power module attached to the mic unit converts the 9 - 52VDC into a small bias voltage that the mic capsule’s FET needs for the microphone to operate.A balanced mic cable has three conductors; Pin 1 is ground, Pin 2 is audio positive, and Pin 3 is audio negative. Most microphones produce a positive voltage on Pin 2 when sound pressure is applied to the diaphragm.
Phantom power is 9 - 52VDC applied across Pin 1 and Pin 2 - and at the same time applied across Pin 1 and Pin 3. The term 'phantom power' was assigned because if you take a measurement across the two audio lines - Pin 2 and Pin 3 - you find 0 Volts DC. The voltage does not affect the mic signal.
