    I bought these to tune my Pioneer Avic-8000NEX [ R  Feb 25, 2016 ]
    Ordered the CD-MC20 Microphone to use with the Auto EQ feature on my Pioneer AVIC-5100NEX. The microphone and feature worked as expected. There is a definite improvement over the stock and personal settings I initially applied by ear after receiving the mic and running the Auto EQ feature. This microphone and Auto EQ will do a better job tweaking the system than the majority of users will be able to do manually. I would recommend unless you plan on using an external processor, an RTA, etc. [ Mike  Jan 07, 2016 ]

    7 questions already asked

    I'm afraid not. The Pioneer CD-MC20 is an Auto-EQ microphone which can only be used with select 2010-up Pioneer DVD, digital media, & navigation in-dash receivers. For more details or to discuss further, please contact an Advisor directly by phone (888.955.6000) or online chat. [ Larry  Aug 29, 2018 ]  Staff
    Don't know. Mine is connected to a Pioneer head unit. Works fine with it [ Hal  Aug 25, 2018 ]
    It can work as long as you find an adapter to shrink that 3.5mm plug down to the 2.5mm needed to fit into the receiver. I hope you can find one! My Bio: [ Paul  May 07, 2018 ]  Staff
    Pioneer's own site essentially matches Crutchfield's description. Pioneer says "Auto-EQ microphone for use with 2010 and later Car DVD Receivers." The 1330 is newer than 2010, and the manual discusses Auto EQ, so my conclusion is that the microphone will work with the 1330. [ DAVID  Sep 29, 2017 ]
    Yes, in fact the Crutchfield product page for that head unit says so. [ Jon  Sep 29, 2017 ]
    Yes it's works with all nex models. And it makes a huge difference in sound quality. [ Jamie  Jan 06, 2017 ]
    If I remember right the connectors are different and won't work through Bluetooth. I bought the auto eq but don't hear a big difference in sound quality. [ Travis  Feb 05, 2016 ]
    In my opinion it gets a fair result but I always have to tweak from there. Apparently it is programmed to get a perfect flat curve or something that does not correspond with my hearing perception ( or my son who has a fairly talented ear). If you have a good ear you will likely end up tuning without it. After trying several times my son and I both have our own custom EQs which are slightly different from each other likely due to my older ears and slight mid-upper range loss. Also it is not permanently installed in the head rest, at least not when used with my headunit. In my headunit, the autoEQ is initiated, then the face plate is motorized down and the microphone is plugged into a plug exposed during the above. The microphone rests on the headrest while the program runs. The faceplate cannot be returned to the normal operating position until the microphone is unplugged at the completion of the Auto-EQ operation. Therefore even if you do like the results of the auto EQ there is no reason to permanently mount the microphone. [ RAYALND K  Jul 20, 2014 ]
    I've used this twice and really enjoy it. Not only does it adjust the 8 band eq, it also time delays the speakers and subs. The eq is set perfectly for a flat response to a microphone and computer but obviously it won't be completely flat to your ear and a audiophile will probably use the eq that the mic comes up with as a baseline and make small adjustments from there like I did. As for installation you just put it in the headrest to run the test. Once it's complete you unplug the microphone and store it in your glove box. The instructions have you run a AUX extention out the back on the unit and tuck it away somewhere so you have an easier time making future measurements without having to take the stereo out and plugging in the mic again. I feel like the time delay function alone was worth the 30 bucks. Plus if you don't get the mic to will probably always wonder if you music would sound better if you had. Christian [ CHRISTIAN  Jul 19, 2014 ]
    Yes you should definitely use it. Our ears can't hear the frequencies like a mic does. You don't leave it installed, you plug it in, place around where you usually sit in car, and let the auto eq run through the frequencies. You will hear a series of tones. That's it listening to the acoustics of your car, and about 5 mins later it's done. Unplug it and put it up until you change speakers, radio loses memory, etc. in other words once it runs the auto eq you are done. Don't have to leave the mic installed. Enjoy! I know you'll see the difference. [ JOSEPH  Jul 19, 2014 ]
    My system requires it to be plugged in to the front of the unit so I can't say much about installation. It does a great job as long as you have a full range of speakers. If you're say missing a sub it doesn't do any good. If you know how, tuning it by hand is a much better option IMO. [ BRONSON  Jul 19, 2014 ]
