This MEI100 microphone connects to select Eclipse in-dash receivers with Auto EQ, allowing you to measure your vehicle's acoustics and create the optimum EQ settings. Just set up the microphone at ear level in your car, and connect it to the left channel of the receiver's auxiliary input.
In Auto EQ mode, the receiver sends "pink noise" through the vehicle's speaker system, then adjusts the built-in parametric equalizer to create the desired EQ curve. This mic works with the CD7200 Mk II and CD5030 receivers. Warranty: 30 days.
