    Basically, mixers take sounds from 2 or more input sources and merge them together to create a single output. The sound engineer controls the way the inputs mix together to create the best-sounding output.

    It’s not absolutely essential, although mixers are helpful for producing a polished and professional-sounding final product. For most home studio recordings, you can get a lot of the same functions out of a sound mixing program on your computer.

    It really depends on what kind of sound you are trying to achieve. For example, if you only have one or two tracks from single mics, you’ll only need 1 channel per track. However, if you’re adding in reverb or other effects, you’ll need more. A good rule of thumb for a basic mixer is to have at least as many input channels as band members.

    How can I set up my mic with my mixer?
    Community Answer
    Through the mic input. It looks exactly like a guitar cable input, but it will have the word "mic" under it.
  • Question
    How do I connect my amps together?
    Community Answer
    Give the amps separate output speakers, but loop the input (or use cross overseas) to split the sound for the inputs.
  • Question
    Does the sound come from the mixer or do I need external speakers?
    Community Answer
    The sound does not come from the mixer; therefore, you do have to use external speakers. The mixer is the bass producer.
  • Question
    How do I connect two audio mixers together?
    Community Answer
    You can connect the main outputs of mixer A to an input on mixer B. Make sure you connect it to a line-input. You can use a standard line-input or an aux-return on mixer B.
  • Question
    How can I hook up three receivers to a mixer so that I can switch between them?
    Community Answer
    Hook one receiver to channel 1, another to 2, and so on. Mute the ones you don't need and unmute it when you need it to switch between them. (Turn the fader on and off if you don't have mute switches.)
  • Question
    When connecting instruments that have their own volume controls, such as keyboards, how do I balance the volume into and out of the mixer?
    Community Answer
    Most digital instruments do not allow you to control the volume once an output is connected. Even in a the case where it allows you to, you must keep it at a constant level, and control it only from the mixer or vice versa. If the balance is the problem, keep all bands at zero (nil) level or at the same level, and control it only by the mixer.

  • Question
    How do I get rid of noise out of my mic output?
    Community Answer
    Noise as seen in mic output could be due to a number of reasons, including faulty microphone itself, faulty mic cables, as well as reversed polarity of the power supply plug of the mixer board. Until you are able to identify the cause of the microphone noise, there's very little you can do. One general approach to cleaning microphone output sound is to EQ out the bad frequencies causing the noise. Also, in the case of feedback, it is imperative to consider the microphone and speaker arrangement as well as pay attention to on stage monitor volumes if they happen to be the case.

    Output Right and Left: Which one supposed to be bass?

    Community Answer
    Do you mean the subwoofer? Either would work, but the best choice is to connect the subwoofer to one of the GROUP outputs. Then you'd be able to adjust its volume independently of the main speakers' volume. Turning off send switches leading to the subwoofer's group on mic channels is also recommended to prevent undesired muddy vocals or pop sounds.
