The ART MX821S is a versatile Definition of Rack:] body=[

A 19-inch rack is a standardized frame or enclosure for mounting multiple equipment modules. Each module has a front panel that is 19 inches (480 mm) wide, including edges or ears that protrude on each side which allow the module to be fastened to the rack frame with screws.

] cssheader=[boxoverheader] cssbody=[boxoverbody]">rack mount Definition of Mixer:] body=[

In professional audio, a mixing console, or audio mixer, also called a sound board, soundboard, mixing desk, or mixer is an electronic device for combining (also called "mixing"), routing, and changing the level, timbre and/or dynamics of audio signals. A mixer can mix analog or digital signals, depending on the type of mixer. The modified signals (voltages or digital samples) are summed to produce the combined output signals.

Mixing consoles are used in many applications, including recording studios, public address systems, sound reinforcement systems, broadcasting, television, and film post-production. An example of a simple application would be to enable the signals that originated from two separate microphones (each being used by vocalists singing a duet, perhaps) to be heard through one set of speakers simultaneously. When used for live performances, the signal produced by the mixer will usually be sent directly to an amplifier, unless that particular mixer is "powered" or it is being connected to powered speakers.

Stereophonic sound, commonly called stereo, is the reproduction of sound using two or more independent audio channels through a symmetrical configuration of loudspeakers in such a way as to create the impression of sound heard from various directions, as in natural hearing. It is often contrasted with monophonic, or "mono" sound, where audio is in the form of one channel, often centered in the sound field (analogous to a visual field).

An audio line comprising three conductors: two carrying signal and a ground (shield) wire, in which one of the signal wires carries the sound and the other carries an inverted copy. When the signal reaches the destination, the inverted copy is flipped and added to the original. Any noise that has been induced into the signal is also inverted. When this is combined with the "uninverted" noise, it cancels it out. Balanced lines thus are less susceptible to hum and can carry audio signals over longer distances. Balanced audio lines typically use 3-pin XLR or 1/4-inch tip-ring-sleeve, phone connectors.

] cssheader=[boxoverheader] cssbody=[boxoverbody]">balanced Definition of XLR:] body=[

The XLR connector is an electrical connector design. XLR plugs and sockets are used mostly in professional audio and video electronics cabling applications, often for microphones. Home audio and video electronics normally use RCA connectors for line level signals generated by a preamplifier. Phone plugs are also used for microphones in home and computer applications.

] cssheader=[boxoverheader] cssbody=[boxoverbody]">XLR Definition of Microphone:] body=[

A microphone, colloquially called a mic or mike (both pronounced /ˈmaɪk/), is an acoustic-to-electric transducer or sensor that converts sound into an electrical signal. In 1876, Emile Berliner invented the first microphone used as a telephone voice transmitter. Microphones are used in many applications such as telephones, tape recorders, hearing aids, motion picture production, live and recorded audio engineering, in radio and television broadcasting and in computers for recording voice, VoIP, and for non-acoustic purposes such as ultrasonic checking.

A TRS connector (tip, ring, sleeve) also called an audio jack, phone jack, phone plug, jack plug, stereo plug, mini-jack, mini-stereo, or headphone jack, is a common analog audio connector. It is cylindrical in shape, typically with three contacts, although sometimes with two (a TS connector) or four (a TRRS connector).

It was invented for use in telephone switchboards in the 20th century and is still widely used, both in its original 1/4" (exactly 6.35 mm) size and in miniaturized versions: 3.5 mm (approx. 1/8") and 2.5 mm (approx. 3/32"). The connector's name is an initialism derived from the names of three conducting parts of the plug: Tip, Ring, and Sleeve - hence, TRS.

Short for panoramic potentiometer. A pan pot (usually on the channel strip of audio mixer) is used to position a monaural sound source in a stereo mixing field by adjusting the source's volume between the left and right channels. Our brains sense stereo position by hearing this difference in loudness when the sound strikes each ear, taking into account time delay, spectrum, ambient reverberation and other cues.

An electrical bus (alternatively spelled "buss"), derived from busbar, is a common electrical connection between multiple electrical devices.

A bus can either allow signals to be transferred between devices, the summing (mixing) of output signals from the devices or the distribution of input signals or power amongst the devices. A bus often takes the form of a wire or printed circuit conductor that terminate at multiple connectors which allows the devices to be plugged into the bus.

Phantom power (usually P48 or 48 volts in pro audio equipment, sometimes lower (e.g. 12 volts)) is a method that sends a DC electrical power through microphone cables to operate microphones that contain active electronic circuitry. It is best known as a common power source for condenser microphones, though many active DI boxes also use it.

Phantom power supplies are often built into mixing desks, microphone preamplifiers and similar equipment. In addition to powering the circuitry of a microphone, in traditional (DC-polarized) condenser microphones the phantom powering directly or indirectly supplies the voltage used for polarizing the microphone's transducer element ("capsule").

A rack unit or U (less commonly, RU) is a unit of measure used to describe the height of equipment intended for mounting in a 19-inch rack or a 23-inch rack (The dimension refers to the width of the equipment mounting frame in the rack i.e. the width of the equipment that can be mounted inside the rack). One rack unit is 1.75 inches (44.45 mm) high.

The size of a piece of rack mounted equipment is frequently described as a number in "U". For example, one rack unit is often referred to as "1U", 2 rack units as "2U" and so on.

Perfect for Definition of Stage:] body=[

In theatre, the stage (sometimes referred to as the deck in stagecraft) is a designated space for the performance of theatrical productions. The stage serves as a space for actors or performers and a focal point for the members of the audience. As an architectural feature, the stage may consist of a platform (often raised) or series of platforms. In some cases, these may be temporary or adjustable but in theaters and other buildings devoted to such productions, the stage is often a permanent feature.

There are several types of stages that vary as to the usage and the relation of the audience to them. The most common form found in the West is the proscenium stage. In this type, the audience is located on one side of the stage with the remaining sides hidden and used by the performers and technicians. Thrust stages may be similar to proscenium stages but with a platform or performance area that extends into the audience space so that the audience is located on three sides. In theatre in the round, the audience is located on all four sides of the stage. The fourth type of stage incorporates created and found stages which may be constructed specifically for a performance or may involve a space that is adapted as a stage.

Balanced audio lines typically use 3-pin XLR or 1/4-inch tip-ring-sleeve, phone connectors.] cssheader=[boxoverheader] cssbody=[boxoverbody]">balanced), +18 Definition of dBu:] body=[ Decibels referred to the voltage equivalent of 0 dBm into a 600 ohm load. 1 dBu = 0.775v = -2.21 dBV] cssheader=[boxoverheader] cssbody=[boxoverbody]">dBu (unbalanced)

Since it expresses a ratio of two (same unit) quantities, it is a dimensionless unit. A decibel is one tenth of a bel (B).We perceive loudness of sound as the logarithm of the actual sound intensity, and dB (decibels) are a logarithmic scale.] cssheader=[boxoverheader] cssbody=[boxoverbody]">dB (Definition of Mic:] body=[ A microphone, colloquially called a mic or mike (both pronounced /ˈmaɪk/), is an acoustic-to-electric transducer or sensor that converts sound into an electrical signal. In 1876, Emile Berliner invented the first microphone used as a telephone voice transmitter. Microphones are used in many applications such as telephones, tape recorders, hearing aids, motion picture production, live and recorded audio engineering, in radio and television broadcasting and in computers for recording voice, VoIP, and for non-acoustic purposes such as ultrasonic checking.] cssheader=[boxoverheader] cssbody=[boxoverbody]">Mic), 29 Definition of dB:] body=[ The decibel (dB) is a logarithmic unit of measurement that expresses the magnitude of a physical quantity (usually power or intensity) relative to a specified or implied reference level.

Definition of Phantom Power: ] body=[ Phantom power (usually P48 or 48 volts in pro audio equipment, sometimes lower (e.g. 12 volts)) is a method that sends a DC electrical power through microphone cables to operate microphones that contain active electronic circuitry. It is best known as a common power source for condenser microphones, though many active DI boxes also use it. Phantom power supplies are often built into mixing desks, microphone preamplifiers and similar equipment. In addition to powering the circuitry of a microphone, in traditional (DC-polarized) condenser microphones the phantom powering directly or indirectly supplies the voltage used for polarizing the microphone's transducer element ("capsule").] cssheader=[boxoverheader] cssbody=[boxoverbody]">PHANTOM Definition of Power:] body=[ The rate at which electrical energy is applied to or taken from a device.
