Audio mixers

In professional audio, a mixing console, or audio mixer, also called a sound board or soundboard, 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.

War nicht schwer, Webseite öffnen und heraus kopieren
Angabe vom Hersteller:
Der C3USB besitzt zwei USB Ports. Sie können jeden Port mit einem anderen Computer verbinden, Sie haben
jedoch auch die Möglichkeit, beide USB Ports an einen Computer anzuschließen. Jeder USB Port des Mixers
erscheint als separates USB Audiogerät am Computer. Sie können gleichzeitig zwei Audiodateien von einem
Computer abspielen und mit zwei USB Kabeln jedes Audiosignal an getrennte Mixerkanäle senden.
Falls Sie diese Option einsetzen wollen, empfehlen wir Ihnen eines der Programme, das mehrere Soundkarten
Falls Sie jedoch solch eine Software nicht besitzen, können Sie stattdessen zwei verschiedene Media Player
Programme verwenden. Dazu starten Sie zunächst das erste Programm, ändern danach das
Standardwiedergabegerät auf den zweiten USB Port und starten danach die zweite Software.
Hinweis: Einige Programme (wie der Windows Media Player) gestatten es nicht, mehrere Instanzen gleichzeitig
geöffnet zu haben. Wenn Sie das Programm ein zweites Mal öffnen, stoppt die erste Instanz die Wiedergabe. Um
dies zu umgehen, verwenden Sie verschiedene Softwareprogramme. Spielen Sie zum Beispiel im Windows Media
Player das Signal für den ersten Kanal und mit Musicmatch Juke Box den zweiten Kanal ab.
Hinweis: Bitte beachten Sie, dass nicht alle Media Player Programme sich daran “erinnern,” welche Soundkarte Sie
beim Starten verwendet haben.
