Mixer

    casperelectronics Mixer

    This is just a simple four channel mixer. The case has wooden sides, an MDF base plate and a wrap around aluminum face plate. The picture on it was cut from an old health textbook. It’s a student taking a hearing test. Great headphones. There are three types of input jacks for each track.

    • stereo 1/8″ jacks for plugging in walkmans, cd players, computers, etc. (uses two channels)
    • RCA jacks for connecting old home stereo equipment
    • 1/4″ jacks for guitar, mic, synth, etc.

      @Hans:
      sorry for the slow response. I’m pretty sure you can make it as high as 15 channels without any problems. This is a very standard circuit and there is LOTS of info on its capabilities and limitations out there if you have the stomach for dry engineer speak.

      Looks like there’s a pot on the output, where does that go in the schematic? Near the 1 meg resistor?

      Simple and effective.
