Also, you can use FET Q1 to adjust the audio signal. 1/4 speaker outputs of the breakout cable to the inputs of your active (powered) studio monitors or amplifier. Secondly, C1 and C2 transmit the signal to VR2 and VR1. Part #: 090-280 Price: $0.73 x 10 - Project Box 5-1/4" X 3-1/4" Part #: 320-430 Price: $4. First and foremost, the audio signal enters the circuit through inputs 1 and 2. Part #: 002-1.1K Price: $0.75 - 10K Audio Taper Stereo Potentiometer 1/4" Shaft. The specific parts I got from Parts Express are as follows: - 1.1K Ohm 1/2W Flameproof Resistors 10pcs. If you're building a mono mixer, you should just use single-ganged pots. That way each channel can be kept separate, and one knob will control both channels. Double-ganged means that one knob controls two inputs at the same time, which is necessary if you have stereo audio. You want a logarithmic pot (aka audio pot) because volume is on a logarithmic scale. A wide variety of dsp audio mixer options are available to you, such as noise cancelling. Tools: - Soldering Iron and Solder - Dremel or Drill - Wire Strippers Parts: - 1K ohm resistors x8 - 10K ohm logrithmic double-ganged potentiometer x4 (* explained below) - RCA panel mount input jacks x10 - project box or other enclosure *About the Potentiometers: A potentiometer or 'pot' is the twisty knob that will act as a volume control. output input1 x param1 + input2 x param2. Sums 2 Signals to 1 Output Input Trims on Channel 1 & 2 Mute/Engage Switches on Channel 1 & 2 Input-Trim Bypass Button Show More. It is also relatively cheap, mine cost me about $20, but you can vary yours to fit your budget. Radial Engineering MIX 2:1 2-Channel Audio Combiner & Mixer.

AUDIO MIXER 2 INPUT 1 OUTPUT PORTABLE
This enables you to easily sum the stereo outputs of a console, recording interface, or portable playback device down to mono, or to mix any two signals together and balance their relative input levels. This project requires few parts and tools. The MIX 2:1 is a simple yet highly useful mixer that passively sums two audio channels down to one.
