If you set the default speaker to this device, you can also use it as a small speaker to play music from your PC But now for the granddaddy, the Polycom RealPresence Trio 8800. It might be expensive, but it might also be worth it. This unit comes with the touch screen controls I mentioned previously, and of course with amazing audio quality expected from Polycom. Polycom touts that this speakerphone is the only one on the market with the capability to share HD content from your own BYOD device for some crazy collaboration. Starting with the bare basics, it would be hard to go wrong with this Jabra 410. With a USB connection, you won’t need an expensive setup to take advantage of fancy touch screens or phone integrations, just plug and play and it’s ready to go. The speaker itself is pretty slim and compact, capable of moving wherever you go, and the physical call controls are a great addition. Of course, a large conference that has a 12-foot-long desk will need more than one microphone. One microphone in the center of the table is not enough. The speaker is going to make a person sitting at one end of the table sound very far away. What Options are Available?

As a well-known name for any audio enthusiast, you know you’ll be buying a quality mic when you go with Audio-Technica. This Pro 44 boundary mic is no different, with a wide-range condenser and what AT calls a “low-mass diaphragm” for a superior performance to other alternative mics. These mics run on batteries with no need for external power, and should provide incredibly clear audio. The included cable should help cut down on the cost of purchasing accessories as well, but the main selling point here is the known quality of Audio-Technica. The MEMS (microelectromechanical systems) microphone is also called a microphone chip or silicon microphone. A pressure-sensitive diaphragm is etched directly into a silicon wafer by MEMS processing techniques and is usually accompanied with an integrated preamplifier. [35] Most MEMS microphones are variants of the condenser microphone design. Digital MEMS microphones have built-in analog-to-digital converter (ADC) circuits on the same CMOS chip making the chip a digital microphone and so more readily integrated with modern digital products. Major manufacturers producing MEMS silicon microphones are Wolfson Microelectronics (WM7xxx) now Cirrus Logic, [36] InvenSense (product line sold by Analog Devices [37]), Akustica (AKU200x), Infineon (SMM310 product), Knowles Electronics, Memstech (MSMx), NXP Semiconductors (division bought by Knowles [38]), Sonion MEMS, Vesper, AAC Acoustic Technologies, [39] and Omron.

It should be compatible with PC, Mac OS, and Windows, among others. It should also support a USB and a Bluetooth connection. Noise cancellation A mute button serves to be of great help while delivering a presentation. If a mic has a mute button, you can mute it whenever you speak something else to someone unrelated to that specific presentation. Long warranty Target Language(s) : The language in which each delegate hears the speech. It can also be called the translation feed. When the audience is diverse enough to need multiple target languages, this can be provided through multiple interpreters using the same system. The rest of the interpreting process remains exactly the same. sometimes referred to as 6.35mm) phone connector on less expensive musician's microphones, using an unbalanced 1⁄ 4in (6.35mm) TS (tip and sleeve) phone connector. Harmonica microphones commonly use a high impedance 1⁄ 4inch TS connection to be run through guitar amplifiers. I didn't think this speaker performed quite as well as from a sound quality standpoint as the Jabra Speak 2 55 (see above), but it is well designed speakerphone that delivers solid performance for its price and does have better battery life than the Jabra (16 hours vs. 12 hours).

But, on the flip side, that massive conference room with a 12-foot-long desk aligned with chairs — just one microphone in the middle of the table is going to make Steve on the other end sound like he’s somewhere out in Guam.

Retrieved July 30, 2013.Some microphones are intended for testing speakers, measuring noise levels and otherwise quantifying an acoustic experience. These are calibrated transducers and are usually supplied with a calibration certificate that states absolute sensitivity against frequency. The quality of measurement microphones is often referred to using the designations "Class 1," "Type 2," etc., which are references not to microphone specifications but to sound level meters. [64] A more comprehensive standard [65] for the description of measurement microphone performance was recently adopted. Aesthetics: The sleek and polished appearance of the systems signals professionalism and respect for all participants. By giving each speaker a personal microphone, it also shows a commitment to valuing each person’s voice.

Range A conference speaker is useless if you can't be heard clearly- which is why our experts test the range of each model. Delegate / Delegate Unit : Refers to all other participants in the meeting who are not the chairman. The delegates each have their own microphone, called a Delegate Unit. These units typically have a push-to-talk button, volume control, voting buttons (optional), and a light that illuminates when the mic is live.

Many microphones have a warranty of two years, but some offer even more warranties. You should buy the ones which have longer warranty periods. What are the different types of conference microphones? Individual microphonesCeiling mics are ideal when cluttering a conference table is not an option. Other types of microphones will take up a lot of space on a table and have visible wires. Having a ceiling mic will help to ensure that conference tables are kept free of annoying wires. Early microphones did not produce intelligible speech, until Alexander Graham Bell made improvements including a variable-resistance microphone/transmitter. Bell's liquid transmitter consisted of a metal cup filled with water with a small amount of sulfuric acid added. A sound wave caused the diaphragm to move, forcing a needle to move up and down in the water. The electrical resistance between the wire and the cup was then inversely proportional to the size of the water meniscus around the submerged needle. Elisha Gray filed a caveat for a version using a brass rod instead of the needle. [ when?] Other minor variations and improvements were made to the liquid microphone by Majoranna, Chambers, Vanni, Sykes, and Elisha Gray, and one version was patented by Reginald Fessenden in 1903. These were the first working microphones, but they were not practical for commercial application. The famous first phone conversation between Bell and Watson took place using a liquid microphone. Enables Language Interpretation: With multi-lingual groups, conference microphone systems are often used with simultaneous interpretation equipment. The individual mics allow the floor feed to be sent directly to the interpreter, so that he/she has a clear audio signal to translate. A frequency response diagram plots the microphone sensitivity in decibels over a range of frequencies (typically 20Hz to 20kHz), generally for perfectly on-axis sound (sound arriving at 0° to the capsule). Frequency response may be less informatively stated textually like so: "30Hz–16kHz±3dB". This is interpreted as meaning a nearly flat, linear, plot between the stated frequencies, with variations in amplitude of no more than plus or minus 3dB. However, one cannot determine from this information how smooth the variations are, nor in what parts of the spectrum they occur. Note that commonly made statements such as "20Hz–20kHz" are meaningless without a decibel measure of tolerance. Directional microphones' frequency response varies greatly with distance from the sound source, and with the geometry of the sound source. IEC60268-4 specifies that frequency response should be measured in plane progressive wave conditions (very far away from the source) but this is seldom practical. Close talking microphones may be measured with different sound sources and distances, but there is no standard and therefore no way to compare data from different models unless the measurement technique is described.
