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).
- Designed for surface-mount applications such as high-quality sound reinforcement, professional recording and teleconferencing
- Low-profile element provides uniform omnidirectional polar pattern with 360º acceptance angle
- Mounts unobtrusively in table-tops, ceilings and wall panels
- Self-contained power module with XLRM-type output connector
- Rugged all-metal case with a two-layer steel mesh grille
- Isolators provide mechanical dampening of mounting-surface vibration
- Requires 11V to 52V DC phantom power
- UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
- Available in two colors: black (ES945) and white (ES945W)
- RoHS compliant—free from all substances specified in the EU directive on hazardous substances

Thank you for your inquiry. This microphone is phantom powered. As for the cost, this microphone is only sold through authorized sound contractors and is not available in stores. You will need to contact an authorized sound contractor for pricing information.Age:Â 45-54

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.

We have conference room, and we're designing a conference table where mic is embedded to it. What is the ideal distance of each mic and the distance from the users?

Answer:Â
Thank you for your inquiry. This depends on several factors. If this is just for audio/video conferencing use with no reinforcement in the room, generally a microphone placed 18 to 24 inches from the edge of the table will pick up 2 to 3 people in a row very well.Age:Â 45-54

I need a solution to enable video conferencing for a rectangular table with 14 seated participants. Has to be cieling mounted, 8' high, due to wiring separation issues. Is the distance from cieling to speakers too far; between 5' and 10' if I use 2 mics? I want to be sure before purchasing whether this is the right product or is there a better model?

Answer:Â
This is a very common request but almost always results in a poor experience. First, 10' is way too far for this microphone and 5' is pushing it. Also, you want to avoid multiple microphones that cover the same area as this results in comb filtering which will make the audio sound even more distant and hollow. You need a balance between room acoustics and the microphone placement and selection. Because the distance between the source (person speaking) and the mic is so far in a ceiling application room acoustics are critical (try for an RT60 time of .5s or less). Speaking of critical... the critical distance will help you determine the useful distance of a mic. Personally, I would recommend you either use microphones which can hang down from the ceiling or you use directional microphones each focused at a specific area and avoid overlap. Check out the 3:1 rule for microphones for additional info. AT makes great mics but I'd have to recommend the Audix M40 for a ceiling-mounted application. You'll need an audio DSP with AEC and adaptive auto-mixing as well. If the performance of the room is important then I would recommend contracting an AV systems integrator or AV/acoustics consultant handle the planning.User Type:Â Live Sound
