In audio, a mixing console or audio mixer is an electronic device for combining (also called "mixing"), routing, and changing the level, timbre (tone color) and/or dynamics of many different audio signals, such as microphones being used by singers, mics picking up acoustic instruments such as drums or saxophones, or signals from electric or electronic instruments such as the electric bass or synthesizer. In the 2010s, a mixer is able to control 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, which are then broadcast, amplified through a sound reinforcement system or recorded (or some combination of these applications). Mixing consoles are used in many applications, including recording studios, public address systems, sound reinforcement systems, broadcasting, television, and film post-production. A typical, simple application combines signals from two microphones (each used by vocalists singing a duet, perhaps) into an amplifier that drives one set of speakers simultaneously. In live performances, the signal from the mixer usually goes directly to an amplifier (unless the mixer has a built in power amplifier or is connected to powered speakers). A coffeehouse's tiny stage might only have a six channel mixer, enough for a duo of singer-guitarists. A nightclub stage's mixer for rock music shows may have 24 channels for mixing the signals from a rhythm section and several vocalists. A mixing console for a large concert may have 48 channels. A mixing console in a professional recording studio may have as many as 72 channels. In practice, mixers do more than simply mix signals. They can provide phantom power for capacitor microphones; pan control (which changes a sound's apparent position in the stereo soundfield); filtering and equalization; routing facilities; and monitoring facilities, whereby one of a number of sources can be routed to loudspeakers or headphones for listening, often without affecting the mixer's main output.Some mixers have onboard electronic effects, such as reverb. Some mixers intended for small venue live performance applications may include an integrated power amplifier. Among the highest quality bootleg recordings of live performances are so-called ''soundboard recordings'' sourced from the mixer output. ==Terminology== Audio consoles are also called "mixing desks", "audio production consoles", "consoles", "soundboards", "boards" or simply "mixers." 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「mixing console」の詳細全文を読む スポンサード リンク
