What could be said about the XLP is that the wire and the pin have a direct relation, in terms of number. The XLP cable and connector are used for audio-related devices.

The 3 and 4 wire cables are widely known for their use but there are other types as well. XLR connectors, also known as canonical connectors, are one of the most common audio connectors used in professional studios to transmit high-quality audio. While XLR connectors are designed for use with audio equipment, they are also used with some stage lighting equipment. The most common type of XLR connector is the 3-pin type, which over time has become the industrial connector for balanced audio signals. If you work with sound equipment and stage lighting, you've probably seen this circular 3-pin connector; of course, different types of this connector from 3 to 7 pins are made for different purposes. In the rest of this article, we will examine what an XLR connector is and what is it for. The name XLR connector is short for XConnector, Locking Connector, Rubber Boot, and refers to features such as locking connectors and rubber boots; although some XLR connectors, today may not have a rubber coating on them. With its special construction, this connector is one of the best connectors for transmitting high-quality sound with minimal noise. XLR connectors are also known as canonical connectors. This is because the XLR connector was originally developed by James Cannon and used by Cannon. Two types of 3-pin XLR connectors are commonly used: XLR male and XLR female. Male XLR connectors are usually connected to the device transmitting the signal, just like an XLR microphone. The female XLR connection is usually where the signal is received; for example, input on a mixer. So for this example, you'll need an XLR-XLR cable with a male connector on one end and a female connector on the other to connect the microphone to the mixer. The quality of XLR connectors can vary depending on the manufacturer and the material used. Different types of XLR connectors The first and simplest XLR connector had three wires and was called a three-pin connector.

But a new generation of multi-pin XLR connectors has been introduced for a variety of devices, which we'll take a closer look at. Three-pin XLR connector (XLR3) The three-pin XLR connector is the most common type of these connectors and is the industry standard for balanced audio signals. Some professional microphones use XLR connectors. In previous years, three-pin XLR connectors were also used to connect some speakers. There are also rechargeable units that use a three-pin XLR connector. For example, XLR ports can also be found in electric wheelchairs and electric scooters. The three-prong plug carries 2 to 10 amps at 24 volts. The three-pin XLR connector is commonly used with DMX512 controllers in lighting fixtures and related control equipment. This connector is also used for cheap DJ equipment. Four-pin XLR connector (XLR4) Four-pin XLR connectors are used in a variety of applications. The four-pin XLR connector is the standard connector for intercom headsets such as ClearCom and Telex. Intercoms are devices that allow two-way communication in work environments such as businesses and factories, some of which have the ability to make calls outside the work environment. Two pins are used for mono headphone signals and two pins are used for microphone signals. Another common use of four-pin XLR connectors is for DC power connections in professional camcorders and related equipment. Some desktop microphones with LEDs also use four-pin XLR. The three pins of the four-pin XLR work just like the three-pin XLR, and the fourth pin is used to turn on the LED that indicates the microphone is ON Air. Other uses for the four-pin XLR include some rollers (color-changing devices for stage lighting), AMX analog lighting controls, and some firefighting equipment. The 4-pin XLR connector is used to connect balanced audio headphones to a balanced amplifier, where there is no common ground between the two channels.

Five-pin XLR cable (XLR5) Five-pin XLR connector for DMX512 digital lighting control. Other common uses are dual-element or stereo microphones (two balanced audio signals with a common ground) and stereo talkback headphones (three pins for stereo headphone signals and two pins for microphone signals). In addition, five-pin XLR connectors are often used for DC power in audio equipment. Six-pin XLR cable (XLR6) Six-pin XLR connector for two-channel intercom and stage lighting control applications. Stereo headphones with balanced microphones also use a six-pin XLR (XLR6) connector. Seven-pin XLR cable (XLR7) A seven-pin XLR connector is used to connect some condenser microphones to their power source. Several models of Le Maitre and Ultratec units use a seven-pin XLR (XLR7) connector for remote control. Relatively old uses of the seven-pin XLR connector are analog lighting control signals and wired walkie-talkies in professional studios. A balanced audio cable is a cable that helps reduce electromagnetic interference or noise in audio signals. Conventional or unbalanced cables carry audio signals over 2 wires. These wires are usually signal wires and ground wires. In a balanced cable there are 3 wires called hot signal, cold signal and ground. Hot and cold signals are exactly the same. The waveforms are completely opposite in phase, if the waveform rises on a warm signal, it falls on a cold signal.

When the signal reaches the end of a balanced cable (such as an XLR connector), the amplifier combines the signal and creates a single output again. If there is interference and noise in the sound transmission path of a balanced cable, the noise will be the same in both wires. This is why amplifiers can neutralize this noise and keep only the original and clear signal. Since you need 3 wires to carry a balanced signal, the most common way to create a balanced connection between two audio devices is to use a cable with XLR connectors; since XLR connectors have at least 3 wires for audio signal transmission standard connectors. XLR connector Price: The price can be an important factor when buying an XLR connector. If the plug will be used in a normal environment, you can consider a cheap plug, but if you want to use it in an environment that requires high quality, be sure to look for higher quality plugs that have lower prices due to various damages that may occur products that are also higher, go for it. XLR Cable Quality: Quality is a difficult term to define for many devices, but choosing a manufacturer known for their quality products will ensure you get a quality connector. A high quality plug will be stronger and can be used in a professional environment. When you buy some lower quality XLR connectors you may find that their locks don't work properly, brands like Neutrik are known for their high quality XLR connectors. Resistive or IP-rated: IP-rated XLR connectors can be purchased with both resistive and IP ratings. The IP rating of these connectors means they can withstand harsh environmental conditions. If you use the cable in an environment that requires protection from moisture, rain, etc. it is best to purchase IP rated connectors.
