[QUOTE="Daniel Postilnik, post: 212305, member: 184"] Hi folks, I'm responsible for the AV system in a meeting room that has high concrete ceilings, 2 bare walls, and a long glass facade. The original system was spec'd with two Clearone hanging array mics about 5 feet above the table - each is a little capsule with 3 mic elements that are processed by a Clearone processor. I trust that the processor is doing its job - we have one running with table mics in a different room and it's great - but the audio quality on conference calls is abysmal, probably because the mics are picking up mostly reflections. I saw that Shure put out a wireless boundary mic ([URL]http://www.shure.com/americas/products/wireless-systems/ulxd-systems/ulxd6-boundary-microphone-transmitter[/URL]) that seems to compete with the Revolabs systems, but much cheaper. The conference room has two ~6 ft tables abutting against each other for roughly 12 ft total length, and there is about 4 feet on each side of the table until the wall. How many mics would be appropriate to cover people seated at the table? I would probably choose the cardioid option to minimize reflections in the signal. Our user base would not mind moving the mics around to bring them closer to a speaker if needed. Would 4 cut it? Will I likely get better results than the ceiling mics? Thanks in advance for help!
