## Overview

The Pioneer CD-MC20 Auto-EQ Microphone is a specialized acoustical measurement mic designed for compatible Pioneer in-dash receivers. It automatically calibrates equalizer settings and time alignment to optimize car audio performance, using a 6.5-foot 3.5mm jack cable for precise placement. This affordable, plug-and-play device delivers professional-level sound tuning, enhancing clarity and balance inside your vehicle.

## Description

The CD-MC20 Auto-EQ and time alignment acoustical measurement microphone enables compatible Pioneer in-dash receivers to automatically adjust the equalizer curve to find the best possible acoustics to enhance audio sound quality. The microphone plugs into the Auto EQ & TA microphone input jack on compatible Pioneer A/V receivers using the attached 6.5-foot cable. The microphone should be positioned towards the center of the driver's seat headrest for optimal measurement results.

Review: Works perfectly if you follow the directions.... - Sometimes it pays to read the reviews and follow their advice...this isn't one of those times! After reading the reviews, I almost decided to not buy this Mic. Heck, even car stereo installers I'm friends with, told me it was a waste of money. Well, at least one has eaten crow! Like almost everything dealing with electronics, you have to follow a set procedure to obtain the best results. Pioneer Auto-eq is no exception to this rule. There is a demonstrative improvement in sound quality with auto-eq on....it cannot be denied. There are a couple "tweeks" that I would suggest; first, get out of the car. Once the countdown starts, get out close the door. I found that the results were much better without my presence mucking up the sonic landscape. Also, the placement of the Mic is paramount and should not be taken lightly. Follow the directions! Oh and the system turns off the hpf on the front speakers, I turned it back on and left the setting where the computer placed it. In fact, the only thing I changed was,I moved the subs lpf a bit up to cover a small gap I felt was in the mid bass range... of course, that was caused by my turning the front speaker hpf back on so.... At the end of the day, I believe this to be an awesome product, especially for those that aren't well versed in the setting of an eleven band eq.
Review: It's not just for Calibrating the EQ. - This microphone does exactly what it's supposed to do. With a compatible Pioneer receiver, it calibrates the equalization and what most reviews fail to mention and maybe even more importantly, time alignment! A car interior has notoriously bad acoustics and on top of that you don't sit in the middle, so proper time alignment and balanced EQ is very important for getting balanced sound and the most enjoyment out of your system. For the negative reviewers that claim that there's no bass after calibration, that's not the mic's fault but only shows how so many people's ears have been conditioned to prefer boomy, exaggerated bass and consider that normal. Even if you are a "Bass Head", please give the calibrated sound a chance! Let your ears readjust over time and appreciate all the other beautiful sounds in the music previously obscured by the boom! You won't regret it! For only around $20, it's not perfect but gets results pretty close to much more expensive professional equipment can do but it takes only fraction of the time and hassle! if you still think the bass is lacking, you should at least use it as a starting point and moderately adjust to taste. Happy Listening!

### ⭐⭐⭐⭐ Works well, but bypass considerations
*by C***9 on November 26, 2012*

Worked very well for me using a Pioneer 4300 DVD head unit. The only issue is that you have to disable the bypass if you have one installed, in order to access the auto equalizer option - to do this, supply 12v to the blue wire coming out of the headunit (at least for a 4300DVD). The hardest part was finding a quiet spot to run the auto EQ function, since I don't have a garage. I definitely noticed the difference in sound quality, this is perfect for those of us that aren't audiophiles and can't be bothered to fine tune every little setting. Well worth the ~$20!
