EV Electrovoice Professional Wireless & Wired Performance Mics AudioTechnica is the WORLDs 2nd largest Microphone Manufacturer Audio2000 Wireless Mics, Wired Mics & Studio Mics Wireless & Wired Microphones from Other Great Manufacturers

MadProAudio has extensive experience in Karaoke, live performance and announcement PA microphones; both wired and wireless. Our staff has been selling wireless and corded karaoke microphones for over ten years and when you specialize in karaoke equipment, you tend to also become well-versed in live performance, recording and PA equipment. We currently are authorized-direct dealers for Electrovoice, AudioTechnica, Audio2000, Best Media and SoundBarrier Pro Audio microphones. But, if you're looking for a Shure, Sennheiser, Audix, AKG, Countryman, Gemini or any other microphone manufacturer, we are vendors for all of the major Pro Audio Distributors in the U.S.. So, we can get you whatever you're looking for at MINIMUM ADVERTISED PRICING. Just call us at
216-251-4444 to check availability.


We're going to tell you up-front that we don't have any EV, AudioTechnica, Shure, Sennheiser, Audix, etc... wired or wireless microphones in many of our online stores and we don't plan on putting any on there, soon, due to the proliferation of counterfeit or knock-off microphones being sold on internet auction sites and/or unscrupulous, unauthorized sellers who set their pricing with no regard for pricing at, at least the minimum of what the manufacturer says the product is worth. We're not saying that all of the microphones on auction sites are suspect, it's just that when trying to sell authentic microphones in a market where pricing for a new microphone is less than our dealer cost (regardless of the reason), we simply refuse to waste our time swimming in a pool of sellers where we either have to compete against questionable products or compete against un-authorized sellers that don't give a damn about this industry and sell product with no pricing guidelines from the manufacturer and fail to inform the purchaser that by buying from them makes the warranty worth less than the paper it's written on. . Caveat Emptor: "Let the Buyer Beware".


EV Electrovoice is the Leader in Professional Microphones

Our MadProAudio staff has been selling EV Electrovoice microphones for around 8 years and have never had one complaint about any of their microphones. . . Oh wait, we had a guy buy a Cardinal mic because it looked cool. Only to find out that he didn't have the proper board to run it (phantom). Other than that, all has been good with EV whether it has been live bands on stage or in the studio, a serious karaoke host that wants his/her customer to sound as good as they possibly can (???), in a church that needs to mic the podium and choir or the CEO that wants a boundary mic to make sure all of his people can hear him clearly on the other side of the world. If you need a wireless or wired microphone that you know is good, try EV.

These are the EV microphones that we normally recommend to our customers. EV has just released the NEW R300 series wireless microphone around the $300 price-point. If you know anything about the price of an Electrovoice wireless mic, then you know they don't really do cheap. But, they decided to take their Clear-Scan technology and apply it to a less expensive line to reach more people. Give us a call if you're interested in any of these microphones or even ones that you don't see here.

FIGURE 1 - Dynamic Microphone Element
Dynamic Microphones
Comparison of microphone types to loudspeakers may help you more readily understand their operation. Dynamic microphones can be considered as similar to conventional loudspeakers in most respects. Both have a diaphragm (or cone) with a voice coil (a long coil of wire) attached near the apex. Both have a magnetic system with the coil in its gap. The difference is in how they are used.

With a speaker, current from the amplifier flows through the coil. The magnetic field created by current flowing through the voice coil interacts with the magnetic field of the speaker's magnet, forcing the coil and its attached cone to move back and forth, producing sound output.

A dynamic microphone operates like a speaker "in reverse." The diaphragm is moved by changing sound pressure. This moves the coil, which causes current to flow as lines of flux from the magnet are cut. So, instead of putting electrical energy into the coil (as in a speaker) you get energy out of it. In fact, many intercom systems use small speakers with lightweight cones as both speaker and microphone, by simply switching the same transducer from one end of the amplifier to the other! A speaker doesn't make a great microphone, but it's good enough for that application.

Dynamic microphones are renowned for their ruggedness and reliability. They need no batteries or external power supplies. They are capable of smooth, extended response, or are available with "tailored" response for special applications. Output level is high enough to work directly into most microphone inputs with an excellent signal-to-noise ratio. They need little or no regular maintenance, and with reasonable care will maintain their performance for many years.

FIGURE 2 - Electret Condenser Element
Condenser Microphones
Condenser (or capacitor) microphones use a lightweight membrane and a fixed plate that act as opposite sides of a capacitor. Sound pressure against this thin polymer film causes it to move. This movement changes the capacitance of the circuit, creating a changing electrical output. In many respects a condenser microphone functions in the same manner as an electrostatic tweeter, although on a much smaller scale and "in reverse."

Condenser microphones are preferred for their very uniform frequency response and ability to respond with clarity to transient sounds. The low mass of the membrane diaphragm permits extended high-frequency response, while the nature of the design also ensures outstanding low-frequency pickup. The resulting sound is natural, clean and clear, with excellent transparency and detail.

Two basic types of condenser microphones are currently available. One uses an external power supply to provide the polarizing voltage needed for the capacitive circuit. These externally-polarized microphones are intended primarily for professional studio use or other extremely critical applications.

A more recent development is the electret condenser microphone (Fig.2). In these models, the polarizing voltage is impressed on either the diaphragm or the back plate during manufacture, and this charge remains for the life of the microphone.

The best electret condenser microphones are capable of very high-quality performance, and are used extensively in broadcast, recording and sound reinforcement.

Due in part to their low-mass diaphragms, condenser microphones are inherently lower in handling or mechanical noise than dynamic microphones. For all of its electret condenser designs, Audio-Technica has elected to apply the polarizing voltage, or fixed-charge, to the back plate rather than the diaphragm. By doing this, a thinner material may be used for the diaphragm, providing a considerable performance advantage over electret microphones of conventional design. Many Audio-Technica microphone diaphragms, for example, are only 2 microns thick (less than 1/10,000th of an inch)!

Condenser elements have two other design advantages that make them the ideal (or the only) choice for many applications: they weigh much less than dynamic elements, and they can be much smaller. These characteristics make them the logical choice for line - or "shotgun" - microphones, lavaliers and miniature microphones of all types.

Attempts at miniaturizing dynamic microphones result in greatly reduced low-frequency response, overall loss in acoustic sensitivity, and higher mechanical or handling noise.

Phantom Power for Condenser Microphones

While the electret condenser microphone doesn't need a power supply to provide polarizing voltage, an FET impedance matching circuit inside the microphone does require some power. This may be supplied by a small low-voltage internal battery or by an external "phantom" supply.

Phantom powering is a technique which delivers a DC voltage to the microphone through the same shielded two-conductor cable that carries the audio from the mic. The phantom power may be supplied either by the mic mixer or from an external supply that is "inserted" into the line between the microphone and mixer input. For phantom power to function, the line between the power supply and the microphone must be balanced to ground, and uninterrupted by such devices as filters or transformers which might pass the audio signal but block DC. Phantom power also requires a continuous ground connection (Pin 1 in the XLR-type connector) from the power supply to the microphone. The supply delivers positive DC voltage equally to both signal-conducting leads, and uses the shield as a return path, or negative. Balanced-output dynamic microphones are not affected by the presence of phantom power, since there is no connection between the shield and either signal lead and, therefore, no circuit for the DC voltage.

Phantom power supplies are available in various output voltages ranging from as low as 9 volts up to 48 volts. They may be designed to operate from AC line voltages or from internal batteries.

Externally polarized or "discrete" condenser microphones seldom have internal battery power. Instead, a phantom power source is used to provide both the polarizing voltage for the element and to power the impedance converter. This type is sometimes called a "pure condenser."

Other Types of Microphones

There a number of ways to translate sound into electrical energy. Carbon granules are used as elements in telephones and communications microphones. And some low-cost microphones use crystal or ceramic elements that are generally OK for speech, but are not seriously considered for music or critical sound reproduction.

One other type sometimes found in recording studios is the ribbon microphone. It is a form of dynamic mic, with a thin metallic ribbon (which serves as both voice coil and diaphragm) suspended between the poles of a magnetic circuit. While it is capable of excellent performance, the ribbon element must be protected against high acoustic pressures or wind, since it is relatively fragile. For this reason, ribbon microphones are rarely seen in sound reinforcement applications or non-studio recording.

Ribbon microphones are often designed to respond to sound from both the front and back, and are sometimes used when a bidirectional pickup pattern is required - which brings us to the next major microphone classification.
