A wireless microphone system enables the user to transmit his voice wirelessly from his transmitter, usually placed within the sound system, to the recipient, also located within the sound system, at a distance of at least one hundred feet. The transmitted sound waves are amplified by the sound system and sent through the speakers to the recipient. In some cases, even further distances could be achieved by using transmitters that have antenna feeders.
There are various types of transmitters suitable for wireless microphone systems. Some of them are; USB (Universal Serial Bus) transmitters, PC Synchronizers, PC Card transmitters, Analog transmitters, RFID transmitters, Gigabit Ethernet transmitters etc. The advantage of using these transmitter is that they can be used even on a non-powered device such as a cell phone or a computer. On the other hand, when connecting a transmitter to a receiver, the latter must be powered by a direct current (DC).
A wireless microphone system can be installed inside the building or outside, inside or outside the building or even in an open area. However, when installing the wireless microphone system inside a building, considerable distance needs to be considered as signal strength would be less. Also, installation of wireless microphone inside a building should not exceed one hundred feet from the building's main source of power. In such cases, the transmitter and the receiver should be placed outside the building.
In order to receive sound in case of two transmitters, a separate transmitter with antenna is needed. A typical two channel transmitter has a microphone integrated in it and can only work with a single channel receiver. In case of a two channel system, the wireless microphone system can be set up in such a manner that both the transmitter and the receiver can be within range of each other. In this instance, two transmitters can be configured as follows. First set up the transmitter so that it is able to send its audio signal on both channels.
Second place the second transmitter at a distance that is comfortable for you. However, this setting should not be beyond your reach as otherwise, it will not be possible for you to receive the audio signal as expected. If you need a wireless microphone system with automatic frequency selection feature, then you need to move further away from the center frequency.
Some wireless microphone systems can only operate at certain frequency rates. This is because they are sensitive to fluctuating radio stations. Some of these wireless microphones have an upper limit which can be adjusted whereas others will not respond to the signal if the rate is higher than they are used to. It is therefore advisable to know your maximum operating frequency before you purchase one.
The ideal setting for a wireless microphone system is when both transmitters can work at the same frequency. There are some transmitters which allow only the audio to transmit while the other also allows the visual data to be sent and received. There are also some transmitters which allow both channels to work at the same time but will have limitations on the audio channels.
Non-diversity microphones can work better with one another but there are times when non-diversity systems can cause interference. If two users use a non-diversity microphone system together, they will produce a stronger signal. When connecting one wireless microphone system to another, ensure that they are both receiving and transmitting their signal at the same time. This will allow them to achieve the best results without experiencing any problems.
In some cases, it may be necessary to consider wireless microphones that offer a bit of noise cancellation. Some people are sensitive to background noises and wireless microphones without noise cancellation are recommended in this case. Wireless microphones without noise cancellation are mostly only suited for use at a specific location, where there are no other sources of noise to block out. This however can be an effective solution in some situations. It is therefore recommended that you check with an experienced professional about the right solution for you.
Sennheiser is one of the world's leading manufacturers of wireless microphone systems. The company has been around since the mid-1990s and continues to produce high quality products that are designed to suit all types of professional as well as personal needs. You will find that most Sennheiser wireless microphone systems have been designed to work well with a range of frequencies. When searching for a suitable system, it is advisable to discuss your requirements with an experienced sales representative and listen to the various options that are available to you.
The vast majority of nady systems are designed to work effectively in the areas of speech level monitoring, dialogue detection, and accent direction. They are also available with a selectable 'room detection' option, which allows you to operate your microphone inside of a room or area. This function is ideal when monitoring areas such as child care facilities, schools and churches. It is important that your microphone is able to operate within the range of frequencies that you wish to use and this should be discussed with a sales representative during your selection.
