    If KX project supports it, that would be my answer. I don't know if it does, or if they are working on it.

    It has 8 channel output. Configurable in any way we want..

    ActiveXover, EQ, delay, effects etc all in digital domain... infinitly reconfigurable....

    That's the same company that I sent an email a while back, here's what I wrote:

    Hi Jan,

    Thanks for sending us feedback and request for next sound card product. All your requests and feedback are taken into serious consideration from our R&D people.

    [Regarding] Currently I'm using the Audigy 2 ZS PCMCIA card with the optical output into my Alpine processor. Ultimately, I'd like to use a sound card, with high voltage RCA outputs direct into my STEG amplifiers. This would only leave me with the need to find a computer program that includes 1/3 octave 31 band eqs, as well as time alignment and cross over points.


    [AZT] We are actually planning on development for RCA outputs (however, it might not be the perfect product as per your description above). In order for us to provide you with precise base management in the PC system, we will need to request C-Media (our chipset developer) for further R&D, thus, we cannot confirm at this time whether this is possible as it depends on C-Media’s willingness for further improvement on their chipset.

    [Regarding] There are a few of us on the mp3car.com forums that are constantly searching for an option like I have mentioned. For some, the solution is to use a cheap USB DAC, like the Silverstone unit. However, there is research that proves that USB DACs can be prone to much jitter. All of the USB DACs I've found, however, only have one set of RCA outputs.

    [AZT] If the USB DAC is using 5V 500A USB bus power, it will not be possible to be free from the jitter. Even if you use the 12V from your car, the system will not be secure depending on the Car battery, cigar jack, and the related circuit board, therefore, you will need to secure these by checking testing, and making some changes in the car. This is however, a great potential product that you have brought up to us. With the current USB chipset that C-Media has, we would not be able to develop such product. However, we can consider it once C-Media release their USB 2.0 chipset.

    [Regarding] Would your company possibly be interested in developing a sound card along these lines? Possibly a PCMCIA card, with a tail of RCA outputs with high voltage outs? Or possibly a USB card with these features? Else, a PCI card for use in either small or no computer case?

    [AZT] For PCMCIA card, VIA and CL have solutions, but for notebook PC, the PCMCIA is outdated, therefore, we are not considering any development based on this.

    We have already road map for USB sound adaptor or DAC planned for next year.

    We do not have plan for LP type PCI card at this time.

    Your feedback helped us understand the Car audio market better and we will definitely look into this market further.

    We appreciate your support for our company and product.

    Sincerely,

    Stephane Bae

    can you show me where you read up about all of this?

    I'll send them another email as well, need to know if it can support ASIO.

    The Auzentech X-Meridian Website

    http://www.auzentech.com/compare.html

    It says "5Vrms (Differential DAC output with gain adjustment / approximately full swing from +/- 8V dual power supply)" - This should be good enough for Car Amp.

    The potential for KX project is enormous, especially for CarPC Audio scene. It's real light on processor resource, infinitly configurable so all the ActiveXOver, GEQ,PEQ,Phase/Delay, Surround, etc can be done in digital domain. The KX project:

    www.kxproject.com
    http://www.driverheaven.net/forumdis...?s=&forumid=67

    I can't find it now, but I read it somewhere that they are working to get the C-Media CMI-8788 chipset (X-Meridian's chip) to work with the KX project. I might be wrong.

    The best soundcard that currently works with the KX project is SoundBlaster Audigy 2 ZS (SB0350) series. SB X-FI's are not compatible with the KX Project, because Creative is not willing to share the architecture with the KX developer. (or something along that line)

    REDGTi, I am sure you know all about KX project, but it might be a good read for someone new.

    I've been reading up on the KX Project, but I was not aware that it has the ability to do X-over functions and all that other jazz...is that truely the case?

    I first found KX project in DIYAUDIO, looking for a way make a 3 way Active crossover using a Professional grade external Soundcard ($399 M-Audio 1010 with 8 XLR outputs).. Then I found that people's been doing this for years ahead of me.

    There are whole bunch of people who has their SB card configured as a 3 way ActiveXover with EQ's and notch filters and etc. Some added a Room EQ compensation with a measurement mic. I think majority of the people using KX are the speaker crossover designers, because it's so easy to change configuration of the XOver and apply EQ and all the other Jazz.

    have you looked into the 1010LT at all?

    http://www.m-audio.com/products/en_u...10LT-main.html

    It looks like it would work for our applications.

    I was also looking at the 1010 but being that it's rack mount, I don't really have a place for it in this install.

    I was also considering this:

    Thoughts on that one?

    All this info is great! I want to get the external sound card options updated with more details and then also do a PCI card section. Please be patient. There is sooo much info it takes a while to organize. if anyone sees any other cards not on the list I will add them.

    Thanks

    I would like to add, dont think anyone is using a emu 0404 pci card. I do studio work been playing music all of my life and upgraded my studio computer from the emu to m-audio and put my emu in the truck.. very impressed with the sound in there now.. wasnt that bad before was using 5.1 usb... but now its unbelievable.. everyone that listens to it is blown away.. but as the post earlier in this thread says.. it is cpu hungry needs a least a 1.3 and says it can run on a 1 ghz but I wouldnt recommend it.. hope this helps someone...

    RedGTi,

    I searched for two days (digging my old computer drives and the CDROM archives) and I just cannot find the website archives where they used the M-Audio 1010 (External version AND LT version) for a software driven Active Xover with EQ and Notch filter and etc.

    I'll be keep looking. I know the quality of the M-Audio 1010 series is really good. If I remember correctly, people at M-Audio were more than willing to share their driver library so people can modify it. What I'd really liketo do, is to use the Auzentech X-Meridian PCI 7.1 card with KX project. The X-Meridian has user replacable OpAmps... yeah Audiophile grade Opamps (8 of them) can be just as expensive as the card itself, but it will make good improvement..

    Meanwhile, a viable solution today (where there are lots of people actually doing this) is to use a SB Audigy 2 (SB0350) with Audiocontrol LC8 8 channel Line Driver.

    SB0350 is a 7.1 channel card, which means we have 8 channels to play with.
    Sonic quality is not as good as the best of the best external soundcard (they call these Audiocards).... but I think it is quite usable.

    So, configure it as 3 way fronts (tweet, mid, woofer) and a 2 subs in rear so that's 8 channels. That should be good enough.


    BTW

    Do you know if anyone makes a car amp with balanced input?
