If you plan to perform on stage with other musicians in front of a large group of people, you have to remember two things. The first of these is the belief that your speech is loud enough to reach everyone in the audience through the use of powerful amplifiers . The second aspect concerns the fact that you and your team plan to do when you are at this stage. Musicians with great power don’t have to worry about the potential risks associated with potykaniem about cumbersome cables when they move on stage, with lots of equipment. Using the wireless system, guitar amplifier helps prevent danger and provide freedom of movement in the place where you want and how you want.
As a high-tech replacement for the guitar cable, the wireless guitar system is an electronic device that transmits an audio signal from a musical instrument directly to an amp and/or speaker without the need for a physical connection. Leveraging a certain radio frequency band, the system uses a transmitter to send signals from the instrument to a nearby receiver, which ultimately decodes the signal and feeds it into an amplifier on stage.
Depending on the signaling methods audio, wireless guitar are divided into the device analog or digital . In the case of a system analog audio data that pass from the transmitter to the receiver, needs to be compressed in the transmitter, is transformed into signal frequency modulation , and then passed through the receiver system from input to the amplifier. The process of compression / expansion is a trademark of analog system and is often referred to as companding .
Analogue system work for bands with very high frequency or ultrahigh frequency . Has been used for many radio and television frequencies VHF is in the range from 30 to 300 MHz, while the UHF range of frequencies ranging from 300 MHz to 3 GHz. Practical and common VHF frequencies are more susceptible to interference and loss of audio quality than the UHF frequencies. Finally, the process of compression and expansion of the signal causes some degree of loss of quality and the noise FM .
In contrast, digital wireless guitar system eliminates the need to compress the signal by converting and coding a signal of audio equipment to digital format and then on the secure transmission of data using the same type of frequency that Wi-Fi routers . Digital encoding of the audio signal to minimize interference and quality degradation as it moves between the transmitter and the receiver, which means that the signal retains the same quality as the original audio input coming from the guitar, even when the sound goes to the amplifier.
Jamming wirelessly and wisely
One of the important issues that you should consider before investing in a wireless system guitar, workout frequency device , which means its ability to detect potential scenarios of intervention and to prevent them without losing the quality of the sound. This is the key feature in the quest for precision sound during the speech live, especially in a situation when there are several musicians on stage who are trying to be in the best shape, and not at the mercy of their equipment. In addition, the more equipment involved, the greater the usefulness of the frequencies useful to prevent problems such as intermodulacja. Some systems are wireless guitars even have built-in scanning features that allow users to automatically detect and select the best frequency. It provides the appropriate clarity of sound, regardless of whether the team moves on stage during the performance.
If you think that longer sessions jamming in Your future, look for systems with permanent lithium-ion batteries are used all the components to not have enough juice in the middle of the set.
Range is another important factor to keep in mind, depending on the size of the object. Many options offers up to 200 feet of space to move around the arena without signal loss, but still good to keep the receiver in sight of the transmitter .
You should then take into account the lifetime of the receiver and transmitter. You should look for options with all-metal construction to withstand any potential shock or falls during the performance.
In the end, think about the size of the locations in which you will act, but also on the number of instruments. This will help in making a final decision on the number of channels with which your device will survive.
Brief history of system wireless guitar
One of the first conventional wireless guitar systems adopted by professional musicians was a Schaffer-VEGA Diversity System , released in 1975, the American inventor Ken Schaffera . It was the first wireless solution, providing a reliable sound and movement, making possible a more powerful performance on multi-level venues and large arenas. The device was finally adapted a famous rock band, including The Rolling Stones, and has been adapted for use as a system of wireless microphones in 1976. Schaffer also acted as a publicist, such well-known American stars of rock music as Jimi Hendrix and Steven Tyler of Aerosmith , among others.
John Nadi released their own wireless system guitar in 1976, under the name “Flying Saucers” . This device had the advantages of lower prices than the system the Schaffer-VEGA Diversity, and at the same time, it was much easier to use than its predecessor. Construction Nadi also provides a better signal-to-noise thanks to a newly developed and patented companding technology. In the 80-ies. Twentieth century invention Nadi Potter was a popular system with many of the best rock bands of the time.
Currently digital wireless guitar system is considered the industry standard for professional features, thanks to the ability to preserve the quality of the signal in the extended ranges, and also due to the possibility of intelligent rate control to ensure the highest quality and most authentic sound.
