  • Overview

    The new Engineered Sound. Contractor-exclusive innovations for every acoustical challenge. And safe haven from Radio Frequency Interference (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).

  • Q & A

    Is this product still available and if not is there a recommended replacement line?


    Yes, the ES945 is available through authorized Audio-Technica Sound Contractors.


    Where can I purchase this Mic? i cannot find a distributor anywhere in Canada. Thanks


    I would recommend contacting our Canadian Representative: Head Office: 21000 TransCanada Highway Baie D'Urfé Québec, Canada H9X 4B7 Tel: (514) 457 2555 Fax: (514) 457 0055


    I am looking for a canadian reseller. can you recommend one?

    Will this work with the ATW-T1007 Microphone Desk Stand Transmitter for System 10 PRO as an omnidirectional option? My situation requires an omni mic solution for multiple round table discussions.


    Yes, you may use an omni microphone with the ATW-T1007. The ES945 will not direclty plug into the mount though. You may either use a gooseneck microphone plugged directly into the ATW-T1007 with an omni element or use the ES945 and a standard XLR cable between the microphone and transmitter. Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at for assistance with this.


    I am looking for a latching mute switch or a mute switch that is latched to mute and frees up the mic when it needs to be in use. I want to mount this into a wall using a single gang stainless steel faceplate. Can you help me identify the right switch to use? Thank you.


    There is no latching mute switch to use but you may use in conjunction with the AT8657/LED where the switch and muting functions may be controlled via a contact closure. Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at for additional assistance with this.


    I am using a Cannon Vixia HF R600 Camcorder that has a 3.5mm TRS Microphone input jack. I need a self-powered "ceiling mounted" Microphone that will connect to the camcorder. I am also looking at daisy chaining 2 microphones if needed for adequate coverage. My conference room is 10' wide and 20' long and will have one 8 person conference table in the middle of the room. I will also need a 20' to 25'cable to connect the Mic or Mic(s) to the camcorder. Do you have any suggestions on what will work. The ES945 description say it is self powered- but the .pdf says you will have to supply phantom power in order for it to operate correctly so I'm a bit confused. Any help you can provide would be greatly appreciated. Thank You, Tim Beck

    ES945 / LED microphone omnidirectional I have a few questions regarding this microphone, in the process of designing a new integrated conference room AV System. Looking for professional sound voice pickup. Would the ES945 omni-directional pickup pattern be optimal for this table layout (4.5' feet wide x 13' feet long, 14 seated chairs) I was thinking of deploying a total of 6 individual ES945 microphones, permanently installed down the middle - center of a wood table. Each seated participant at every 2 chairs, would have 1 mic in front of them at about 2.25' feet away ( 27" inches to edge of table). Do you think this range is too far for voice pickup? I do not want to rely heavily on the DSP programming for increasing gain. Verify if wired to a Biamp DSP, they are fully compliant? Logic to include: Crestron mute, individual mic voice gain increase / decrease, visual indicator lit on microphone if pressed ES945/LED Omnidirectional Condenser Boundary Microphone with Mute Switch and LED Indicator Thank You


    The ES945/LED will not provide a logic in/out for the Biamp DSP. To achieve remote capabilities over Logic, you would use the AT8657/LED Socket and add the ES945 (non-LED version of the mic) to it as the microphone element. Will these microphones be used only for conferencing? Will you be trying to provide voice lift / sound reinforcement in the local room? Six omnidirectional microphones within a 13 foot span is too many microphones. You would have some phase issues. if a person is to be seated at each end of the table, we recommend placing a mic 2.5 feet from each end, then placing a third mic in the center of the table which will be 4 feet from either mic.


    Room size and coverage question I have a 30' x 30' classroom with 9 foot drop-tile ceilings. Participants will be seated. How many microphones would I need to cover the entire room? And which would work better -- the omni or cardioid model? Thanks for your help!


    Please contact the Audio-Technica Audio Solutions Team with your inquiry. You may email them at, or you may call them at 330-686-2600. Thanks!


    Designing a video conference room with boundry mic(s) in the ceiling The video display will be wall mounted with sound reinforcement speakers on each side. How do I determine proper microphone coverage and will the sound reinforcement be a problem.


    Thank you for your inquiry. Folks seated at a table will be at least 4.5 feet away from a mic (with 9 foot ceilings). The mics will pick up the voices, but will also pick up a lot of the room and sound somewhat "distant". This may be ok with for your application, but I'm afraid you may not be too happy with the sound. These work much better when mounted in the table top. Another option is hanging microphones such as our U853R becuase you can hang them closer those speaking.


    using multiple ES945 mics Hi - is it possible to 'daisy chain' 2 or 3 ES945 mics or does each mic have to be routed through a mixer many thanks


    Thank you for your inquiry. It is best to home run each mic to its own channel for several reasons. First, you can control and EQ each on their own. Secondly, when you "Y" two mics together you change the impendence of the mics which will alter their performance, mostly in volume. Thirdly, depending upon the phantom power supply on the mixer you could put a strain on its limits and also affect the performance of the mic. It may very well work "ying" them together, but it is not optimal.
