Q:ES945 / LED microphone omnidirectional
A: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.
Q:Room size and coverage question
A:Please contact the Audio-Technica Audio Solutions Team with your inquiry. You may email them at email@example.com, or you may call them at 330-686-2600.
Q:Designing a video conference room with boundry mic(s) in the ceiling
A: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.
Q:using multiple ES945 mics
A: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.
Q:Do you have an AutoCad drawing
A:Thank you for your inquiry. Please contact our Audio Solutions Team at 330-686-2600 ext 5000. They will help with this.
Q:Can this be plugged in a video camcorder?
A:If your camera has a 3.5mm TRS (Stereo) microphone input, then you will NEED the following:
Q:Ceiling Mount for Conference Table
A: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.
Q:What is the pick-up of this microphone?
A: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.
Q:what you mean by phantom power?
A: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.
Q:How can I determine quantity required per room size?
A: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.
