Customer Question

I have a Yorkville Audiopro Micromix SP12 Powered Mixer. The unit powers on, the led clipping indicators function as they should but there is almost no output when I hook up the speakers. It has a circuit breaker buttone next to the power switch but it doesn't seem to do anything. What might be the problem?

Hello Sir or Madam and thanks for choosing the Electronics category.

  • The Audiopro Micromix SP12 requires 4 ohm speakers.
  • Try connecting (2) 8 ohm speakers in parallel to present a 4 ohm load to the SP12.
