i know what imprint does, but whats the difference between the imprint specific for the 9887 and the imprint that many other of their head units work on
The only difference is that with the 9887 it's got the Imprint chip built into it so you only need that Imprint softwhere and adapter where as the others don't have it so you need the entire Imprint kit. Check the Alpine web site and look at the accesories for the 9887 vs the other decks and you'll figure it out better than I can explain.
9887 has built in Imprint and just need the KTX-100EQ calibration kit, but others are ready for Imprint addon PXA-H100 and the calibration kit KTX-100! get it?
its some kind of sound processor that measures the distortion when ur speaker play in ur vehicle and refined that signal into the HU and u can have differrent sound stage //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
there is also another one yet the pxe-h650 for use with factory systems. Also works well for the 9887 from what I here because when you use the imprint for the 9887 and have it in malti eq setting (imprint tuned mode) you can only adjust the trouble bass sub control and fad/balance. when you use the pxe-h650 you can also control the x over points for each rca rather than the imprint doing it for you. By using the pxe-h650 you can still use your eq's in the 9887 to do any fine tuning you want to that the imprint might now have done the way you like. From what I have read the imprint is great for people like myself that don't know how to tune really well using something like the h-701 combo with 31 band graphic eq's for each rca and a parametric eq for each rca output. With the h650 you have 4 choices of slopes for the imprint eq with the 9887 imprint you only get to choose one of 3 also. It does adjust like 500 points in the eq with the imprint along with the time alignment (auto eq's your x overs on the 9887 imprint not sure if you can auto x over on the 650) I know nothing at all about the other one you guys are talking about for the other alpine cd players. By the way this is stuff I have learned on forums not from personal use.
