They are more commonly know as radio mics or wireless mics, where the original audio cable is replaced by frequency transmitting technology. Radio mics can now transmit audio through radio waves in FM, AM, UHF, VHF and various digital formats.
More advanced models will allow you to select various frequencies to transmit over, helping avoid interference with other electrical transmitters that might be using the same frequency, and also enabling the use of multiple microphones at the same time.
It is thought that the primary radio microphones derived from the original compander microphone developed in 1976 by Nady Systems, who was honoured in 1996 with an Emmy award for his technical contribution to the technology field.
Radio Microphones - Plus Points
Using radio mics is very advantageous for the user. A starting advantage is that radio mics eliminate the health and safety risk of trailing microphone cables. Secondly, and as a result of this, you give the freedom of movement to the wearer of the microphone as they are not joined via a cable. Another plus point is that you no longer stress any cables by flexing them, which can frequently result in damage.
Disadvantages of Radio Microphones
Despite having such advantages, wireless microphones also have some select disadvantages. Firstly the two way radio batteries used do not always last very long as the radio microphones are very thirsty when it comes to power consumption. Radio mics are also hampered by range, with the furthest signals normally only achieved by the larger, more expensive models. Interference from another electrical appliance is also a possibility which would lead to a disruption of the signal. Finally, to avoid being on the same frequency and clashing, you are limited to the number of radio microphones you can use.

They are referred to as radio or wireless mics but are actually a case in which the original audio cable was replaced by a frequency transmitter technique. Radio mics are commonly used in transmitting audio by radio waves such as AM, FM, VHF, UHF or any other digital format.
The better ones operate from numerous frequencies that they use for transmission. That is why they hardly ever experience any interference by other electrical transmitters that are within the same frequency. They can enable the use of many microphones at the same time.
The very first type of radio microphones started as compander microphone development way back in 1976 and was used by Nady Systems. They were given recognition in 1996 and given an Emmy Award due to their technical input in the technological sphere.
These mics have many advantages because it enables the user to hold to some health and safety standards. They can now work without exposing themselves to too much risk due to what used to be the trailing cables of the microphones.
Then there is the advantage of easy movement because the wearer does not have to use any cables trailing the microphone. It used to be the case that the cables actually had some strain or stress because of the way they were tagged and pulled all the time. This used to cause them easy damage.
It might look like the advantages of the wireless mics far outweigh the disadvantages but wait a minute. What about the fact that the two way batteries are now not very long-lasting and they use much power?
Another disadvantage is the fact that the signals are normally hampered by the distance. They will require very strong and expensive batteries if you want to receive strong signals at a further distance. Interference is also caused easily by some electrical appliances that are within the same range.
It requires that one limits the number of radio microphones that can be used simultaneously in one given range.
Audio mikes that used the cables for signal transmissions have long since been replaced with wireless mikes. Also called Radio mikes, they use radio frequency technology to transmit the audio signals. They are capable of sending signals through FM, AM, UHF, VHF and various digital formats.
The most modern mike sets come equipped with frequency selection modes with which you can set the required frequency without having interference from other transmitters operating at the same frequency band nearby. You are now able to use multiple microphones too at the same time.
The current radio microphones owe their origin to the first original compander microphone that was built by Nady Systems in 1976. He was honored with Emmy award in 1996 in honor of his contribution to the field of technology.
Radio mikes are wireless and hence it is easier for the performers to use them on stage and it is a lot safer too when compared to the wires and cables dangling from wired mikes.
The Radio mikes being wireless have provided freedom of movement and performance to the artists who perform on stage. They can freely move across the stage without having to drag or bother with the cables. The handling staff too need not bother with managing and joining cables etc.
Though Radio mikes are very good, there is yet one disadvantage when it comes to the battery life. The radio batteries tend to get drained out very fast and do not last long. The reason being that the radio microphones use up more power and drain the batteries in no time.
Radio mikes operate within a certain range only. This could be a drawback and you might have to buy higher end equipment to get wider range. Then there is also the risk of disruption of signals due to other equipments being used in the same frequency in near by area.
Many times you will be constrained to use fewer numbers of microphones to be able to retain the clarity and avoid clashing of frequency.

Speakers are one of the important parts of any music systems. It is an electromechanical transducer through which the sound comes out. The power of a speaker, generally, determines the quality of the sound. The accuracy of the speaker is one of the primary concerns in determining the ultimate output quality the speaker. The performance usually depends on the ability to reproduce a signal without distorting it.
Price versus Quality Battle
There are a number of popular brands of speakers that are available in the market capable of producing quality sound at affordable prices. There are high quality speakers too, that are quite expensive also. But most of the popular brands look at the quality price ratio aspect of their manufactured speakers.
Popular Brands of Speakers
Some of the popular brands of speakers and audio products include, Behringer, Blackheart, CBI, Celestion, Crate, DBX, Dunlop, Edirol, Elctro voice, Eminence, Epiphone, and EVH.

Behringer
The Behringer has some exclusive range of PA loudspeakers that have some significant differences from the other popular brands of the speakers. Majority of the PA systems are big and heavy, but the ones made by Behringer possess an efficient design concept. They are capable of producing superb sound even at the most extreme of levels. Some products also contain an integrated sound processor to have a better control of the system. The noise level is also low to enhance the output.
Yamaha
Over the years, Yahama has been a major player in the field of audio performances. It has reached everywhere in studio, concert hall, and into your own homes. The high point of Yamaha manufactured speakers are quality production, sonic precision and audible detail. An Yamaha speaker system includes soavo, performance series, in wall custom series, outdoor series and more.

The clean low bass is provided by the high quality sub woofer, along with the mini stereo jack connection, which allows the high quality audio output from digital music players, stereos, computers and portable listening devices.
Earlier on we used to have Audio mikes that used cables to transmit the audio signals. Long since these have been replaced with wireless or radio mikes that use frequency based transmission technology. They operate through radio waves and can transmit audio signals in FM, AM, UHF, VHF and various digital formats.
The advanced mikes are equipped to enable you to select a particular frequency band to transmit the signals from the mike so that it does not interfere with any other transmitter that can be operating on similar frequency. Coupled with this you are also able to use multiple microphones at the same time.
Nady Systems holds the honors of having built the first compander microphone that was built in 1976 and the current radio microphones owe their origin to him. He was honored with an Emmy award in 1996 for his contribution to the technology field.
Today wireless mikes have made it very easy and convenient for users to use while performing. Unlike the mikes with cables running all over the place, the wireless radio mikes are safer to operate.
The wireless Radio mikes have made it very comfortable and easy for performers to use. Today they are not hassled with having to drag cables across the stage and are able to move freely across the entire stage without being bothered. Even the handling staff need not bother with joining cables and managing the cables etc.
Though the Radio mikes are very good and advantageous to have, the draw back seems to be the fact that the two way radio batteries tend to get drained very fast and do not last long. The radio microphones guzzle power fast and in large amounts.
One other shortcoming could be the limited range within which the radio mikes operate. To get wider range you would have to buy higher models. There is also the risk of signals getting disrupted due to any other appliance or equipment operating within the same range.
You will often have to limit the number of microphones that you use, to ensure clarity and clear frequency without clash.
