Imprint good and bad

Written By James T, Laurel , Maryland on Monday, October 28, 2013
Crutchfield Customer Review (What's this?)
 
The imprint gives you plenty of options.
Pros:
The 4v pre-outs made a total difference with my sub amp. It sounds absolutely great. I love sound quality.
Cons:
After loading the imprint software up , it would never actually connect to the imprint itself after trying 3 different laptops I gave up on the tunning of the imprint.

Alpine KTX-H100

Written By Adam A, Arkansas City, KS on Saturday, December 29, 2012
 
Installed a malware packer upon installation, avast didn't pick it up but comodo did. I shrugged it off as a false detection. The next night my facebook was logged and locked from somewhere in seoul, south korea. Scanned pc with malware antibytes and it picked up 2 packers. Scanned the cd itself just now to make sure, the malware packer comes from the IMPRINT_soundmanager.exe

Worst software I've ever used in my life, only works with xpsp2 and it is so strict about this. I tried with sp3 to begin with. ERROR 2 ERROR 2 ERROR 2 Tried with win7 64 ultimate, turns out there are no usb drivers for 64 bit. wouldn't get past the open port error. Read absolutely everything about error 2 online Had to install virtual box with a xpsp2 iso but after dealing with this for 3 days i have yet to run it and to the point i really don't care.

The pxa itself is great and if you read how to time correct and set it up yourself its amazing. You really don't need the ktx unless you're lazy or don't know what you're doing.
Pros:
nice mic
Cons:
malware infected / worst software I've used in 20 years.

Can use extension cable

Written By Banndit, Canada on Saturday, July 14, 2012
 
@SirSteve @tdrouill You CAN use a USB A male to A female extension cable and a STEREO 3.5mm shielded M-F extension cable (like monoprice.com item 5587) and leave them plugged into the unit so that you can just plug in your laptop and the mic while leaving the unit hidden where you installed it.
Cons:
Alpine needs to make the instructions clearer about switching ALL # switches on the head unit to external processor.

too much mid range

Written By DetroitJake, Royal Oak, MI on Thursday, November 24, 2011
 
I have built my own home speaker enclosures, after reading engineering based books on the subject. I'm a mechanical engineer by trade. My car is outfitted with nice Danish drivers (Dynaudio and Peerless) (The sub is JL). And in my opinion, this software is a let down. You don't really get a whole lot of options on how to set up your sound. And yes I like FLAT. But no this software doesn't entirely flatten out your sound. I wish I could attach the result. It killed my treble and bass. Way below flat. So that means somwhere in the software I can just bump that back up, right? No such luck. The software is like press the button and hope you like it, or turn it off, and do it manually with the head unit. You have three EQ curve selections, all of which are not good. What I wanted was a nice HMI into the capability of the DAQ in the Imprint module. If the DAQ can do '500' points of correction, why can't I manually tune this more, through a nice PC screen instead of hitting back and forth in menus on the head unit. I run the EQ flat on my head unit (no correction) and it sounds way better than the Imprint software corrected EQ curve. Alpine, please consider a massive revision to this idea. Its a great idea, but needs way more user adjustability. If we consumers didn't like adjusting the sound to our liking, we wouldn't be installing custom aftermarket stereos. We would just live with the factory sound.
Pros:
I like the idea of it.
Cons:
See Review.

Good Mid and Highs, not so good Subs

Written By CarStereo1971, Henryetta, OK on Wednesday, December 01, 2010
Crutchfield Customer Review (What's this?)
 
I liked the idea of tuning the system, but not to sure about not being able to adjust it like
my home stereo with its built in MCACC which adjust distance EQ, but allows you to
tune it to your taste or maybe set crossovers on subs or a least know where they are. I
use T1500 to 2 Alpine Rs mono amp now sounds like 1 8" sub. Software adjust the
subs as stereo left then right, but both woofers are playing so I believe this might be a
little reason the subs get set so low. Alpine said designers were not into bass, but that
is what subs are for. Alpine said to set the sub amp a 1/4 way and notice one reviewer
said he set his off, so guess it is trial and error now. It is to bad setup removes
adjustments in the deck. Now only Bass, treble and sub adjustments are there, but just
not sure the frequency off hand the bass adjust be nice to have a 40 Hz adjustment but
that is just me. The over all sound quality of the music is great with unit, and if the bass
can be fixed, it will OK. Miss EQ adjustments as well as sub.

set things straight

Written By Jeffrey, kingston PA on Saturday, July 10, 2010
 
i have alot of experience with this product, that being said id like to set some things straight.

first of all, the threaded bottom is meant to attach to a tripod. this device will only work properly if used with a tripod that can make the mic measure at ear level, and also away from the seat.

I have personally used it on Windows 7, Windows XP, Windows vista, and in a vmware virtual machine on MAC. It has no issues with any os i have ever tried, and anyone with any level of computer knowledge should have no issue using it. The software can be quirky, but it does the job and works well.

Works but Windows only garbage

Written By Gedaliah, Morristown, NJ on Monday, February 01, 2010
Crutchfield Customer Review (What's this?)
 
This review is in two parts, the software and the tuning results.

First, the software - As I mentioned in the title, this is Windows only software. I use a Mac with VMWare fusion and this did NOT work with the XPSP3 virtual machine. I received the dreaded error code -2. Of course this error message is pretty much useless. Crutchfield support wasn't much help. Just for the heck of it I installed this software on a Windows 7 laptop. I received a warning when I installed the USB drivers but tried it anyway and it worked.

In my book, Windows only software gets a maximum of 3 stars when it works perfectly on the XP Virtual Machine. I give 0 stars for this software. Useless error messages, warnings when installed on a modern Windows OS, and it didn't work on the VM.

Second, the results - Lots of info on the web regarding tuning. I turned the amp gain for the subwoofer all the way down and performed the 6 point calibration. It took about 30 minutes. The results are outstanding. After calibration I turned up the amp gain on the subwoofer. Bass is nice and tight without being overbearing. The soundstage opens right up. I could never have achieved this level of tuning manually. I'm impressed.

Overall, I recommend this product. Too bad the software made this a much more painful than necessary experience.

Warning for Non-Windows XP owners!

Written By Ken, Hazel Park, MI on Monday, September 14, 2009
 
Bought this to calibrate the Alpine PXA-H100. In the description, says this product works with Windows XP only. I thought, maybe the description was old. I took my Windows Vista laptop and. . . nothing. Got a communicaiton error. Called the tech support people at Alpine, and they informed me that, "When they said Windows XP, they meant Windows XP." Further, they don't have any plans right now to make an updated version of the software. Are you kidding me? XP is two O/S's ago! Who has a laptop with that on it?

Good Hardware--Horrible Software

Written By Greg, Washington DC on Saturday, June 13, 2009
Crutchfield Customer Review (What's this?)
 
The end result is good but this software is horrible at best. I have over 20 years experience as a Chief Engineer in top ten radio market and microsoft certified. It took me over an hour to run one position with this software because it kept locking up. The laptop was a top of the line XPS Dell with XP Pro. I had to keep hitting close and then cancel to get it to release about every 2 minutes.

Make sure you lower your subs all the way down and then turn them off as the software tends to flatten out things. Also, make sure to turn the ext ap switch of the H/U on or it won't work.

Also Alpine why design a mic that can't be clipped in position? This model is designed to placed on a hard flat surface. Personally, I don't know any cars that have little blocks near their headrests.

I was going to keep this software initially, but will be returning it as the GUI interface is so clunky and poorly designed I can do a better job. Alpine clearly did not test this software properly. If I was a normal user I would have returned the whole thing due to poor interface.

The processors RCA inputs are staggered instead of equal lengths. This makes it very difficult to do a clean hidden install.

If not for all my good prior experience with Alpine this would have been MRA'd first thing Monday morning.

The processor does a good job so I will keep it, but not impressed at all with the software.

Insane Difference

Written By Tyteflows, Miami, FL on Monday, April 13, 2009
 
This absolutely, without a shadow of a doubt, will improve your sound like you are sitting front row in a theater. If you are a true audiophile you owe it to yourself to purchase this calibration kit to reach new heights in your listening pleasure. This module WILL NOT make your system louder by any means, actually my decibels dropped off somewhat, but what you gain is pure symphonic luxury. This module along with the calibration kit turned my SUV with a loud stereo into a Sound Capsule with incredible realism. I cannot stress enough how good the imaging in my truck is now. When I close my eyes I cannot tell where the sound is coming from in my truck, it sounds like it is coming from the middle of my head, and that puts a huge smile on my face. Also, purchasing this calibration kit singularly makes sense as you may have several cars or friends with Alpine Imprint ready head units, but only need one Calibration Kit for all of them. Its also nice that Alpine has decided to charge for upgrades or add-ons as the average Joe might just be happy with his head unit and would never use the Imprint option if it was attached internally, it lets Alpine make head units cheaper for people who dont really care but makes them upgradeable for people who do, and lets be honest, your paying about $500 for all the bells and whistles of an Alpine 9886 or similar Imprint head unit, isnt that what you would expect to pay anyways for the industries finest?

Another Waste of Money

Written By Joe, Maryland on Sunday, April 12, 2009
Crutchfield Customer Review (What's this?)
 
This was a monumental waste of money and time! I bought this for the sole purpose of using it with the Imprint software. After 6 hours of tuning and re-tuning, I'm giving up. This is the last piece of Alpine I'll ever buy. I've had to dig deep into many audio forums to learn how this over- priced piece of hardware (and companion software) is supposed to work. Why? Because the instructions give you nothing but a brief overview of each new function in the dizzying array added to the already poorly laid out options on the head unit (in my case a iDA-x100).

I've re-tuned about 15 times and each time I get different results (none have been great). The staging does improve but there's a huge loss of bass and the extreme highs (ride cymbals, hi hats, etc).

In a few years, we'll all look back on these purchases and know why no one buys Alpine audio any more.

Alpine KTX-H100

Written By David, Dothan, AL on Monday, March 30, 2009
Crutchfield Customer Review (What's this?)
 
Works great, a must have to go with your imprint processor. If your head
unit has a switch (NORMAL-> EXT AP) and all compatible head units may
have it, I don't know, remember to set the switch! If you don't, the sound
is poor and you get no error in software as to what you did wrong!

A MUST with the PXA-H100, but...

Written By Matthias, Northville, MI on Sunday, January 18, 2009
Crutchfield Customer Review (What's this?)
 
The most important thing: The sound improvement is absolutely amazing. I fiddeled around with the settings on my own for a week or so. No way, i could have achieved those results on my own.

But first of all it is ridiciulous, that this 5.50$ microphone and the SW does not come with the sound processor in the first place. Alpine charges you really for every extra screw.

And then, after the new settings are downloaded in your headunit, you are not able to modify them anymore nor review them. You just can modify treble and bass, which is all you need, if it would be really perfect. But its not.

For example it was setting my front speakers all the way down to the lowest frequencies. The result was, that the speakers were reaching their limit really quickly (of course! for the deep stuff i have a subwoofer). So i had to manually cut the low frequencies from the front system with the built in crossover from the amp. That suxx. I want to play around with the optimal setting from the headunit, and not crawling under the seat or in the trunk. Btw, no sound difference up to 70Hz.

Furthermore, i am under the impression, that i have a phase deletion right next to my head. I would prefer to play around with the time alignment or the phase, to maybe get rid of this. But no way.

After all, i am very happy with my system though. Imprint for the win.

For my 2005 Jeep Wrangler

Written By tdrouill, Golden, CO on Tuesday, December 02, 2008
Crutchfield Customer Review (What's this?)
 
The software sends sounds out the speakers and analyzes the response of
your interior from all seating positions. It calculates a digital filter that
compensates. The result is nearly ideal sound from your stereo. If you
purchased a PXA-H100, this takes the guesswork out of it. Once a
calibration is run, you can adjust bass, treble, balance (L/R) and fade (F/R)
to your liking.

Notes:

1. The instructions say to reboot after installing the software. DO NOT
SKIP THIS STEP. The software freezes if you run it without rebooting first.

2. Regarding bundling with the PXA-H100: if I install an Alpine stereo in my
wife's car, I only need one copy of the software and one mic. For that
reason, I'd rather see it kept separate than have to pay extra for the PXA-
H100 and end up with two mic's and two CD's.

3. The microphone must be located at "ear" level, moved among six
positions in the vehicle. A camera tripod makes this easy to do. I borrowed
a tripod from my neighbor. If no tripod is available, the mic is small and light
enough that it could possibly be hung by a string taped to the ceiling, or
taped to the head rest.

4. The PXA-H100 needs to be installed somewhere that the USB and mic
cables can be plugged in for tuning, then unplugged. Don't locate the PXA-
H100 somewhere totally inaccessible. You won't run the calibration very
often, but when you do, you must plug cables into the PXA-H100.

Does what it claims but...

Written By SirSteve, FL on Friday, November 07, 2008
Crutchfield Customer Review (What's this?)
 
First off, why this is not included in the PXA-H100 is just a lame attempt to get more of my money (and they succeeded but Alpine when down a notch in my mind). You have to have this software and mic in order to use the PXA-H100. Makes absolutely no sense Alpine!! Then Alpine wants you to take a tri-pod inside your vehicle for the mic. Yet another accessory needed for optimal results. My biggest complaint is having to have the microphone unplugged in order to have the headunit function. How many people will actually have access to this unit in order to plug it in and unplug it each time? I would be better engineered if there was a mic on/off button instead... or a mic extension so you can run the female end of the mic input to another location (I tried this by purchasing a 3' mic male to female extension but as soon as the extension was plugged in, the headunit went into Imprint mode and did not allow me to do anything else until it was unplugged).

Why isn't this included with the imprint?

Written By Jones360, Olympia, WA on Tuesday, October 21, 2008
 
I was also wondering why this isn't included with the imprint. I can maybe
understand having a more advanced sound processor that's sold seppratly
but to have another component sold seperatly that is pretty much needed
for the Imprint to function is kinda lame......

Could use *some* improvements

Written By Daniel, St. Louis, MO on Sunday, September 14, 2008
Crutchfield Customer Review (What's this?)
 
There were a few glitches in getting my Imprint unit setup with this package. First of all, it shouldn't be too hard for Alpine to write a Mac OS version of this measuring and curve adjustment program. Since I didn't have a machine running windows XP between myself, my family, or my friends, it was weeks before someone could call in a favor to let me borrow their laptop.

Besides that, the instructions failed to mention that after curves are ported and applied to the Imprint unit, you need to disconnect the microphone and usb cable. I had my imprint unit installed behind the dash and had planned to keep them connected if I ever wanted to update for new components, requiring me to take apart the dash AGAIN just to make this work. This little bit of information was something Crutchfield didn't know, and took even the Alpine support people some few sessions to figure out.

After it was all said and done, though, my factory system sounds immensely better. I'm a musician and producer in my spare time, and it took the system in my truck from sound like the components were sitting on the floor to being fairly close to studio monitors positioned as the would be or production work.

Way to go Alpine, just fix those little problems you let fall through the cracks, and you'll have a winner. Why isn't this included with the Imprint unit, anyway?
