    Car pc/ Sony XPD-210eq

    I have a Question I would like to get ideas on. I want to go with a carpc in the place of a hu but I am really worried about the quality of the soundcards available. I have a sony Mobile es XDP-210EQ that is a digital pre-amp/EQ/crossover. It has a digital optical in and from what I understand 20 bit burr brown DAC's.

    My question is does anybody think it is feasible to make a software program to control this via a pc?
    If this could be done It would seem It would even be possible to control volume via this unit.

    You'd be surprised at the quality of a good soundcard.

    Software can perform many functions of your sony piece at greater bitrate's than are available in most processors and the accuracy is pretty amazing in my opinion.

    I have not heard of anyone attempting to hack sony's UNI-LINK, but who knows.

    I have seen it done but not on this scale. Sourceforge has some source to emulate a CD changer on unilink. It also uses a simple rs-232 adapter somebody built. but it doesn't do what I would like to do. I havent been able to find a soundcard with the same quality of DAC's as this unit. I have seen some USB and fire wire DAC's of this quality but they are very spendy, and dont have a 31 band eq or digital time alignment or 3 pairs of line outs

    I did notice a thread on here that interested me using the Beringer dcx2496 that interested me the only disappointment I have with it is it has no on board volume control

    FYI the 210EQ has different DACs for the Front/Rear(AKM 20-bit Delta-Sigma DACs) and the SUB.(1x NEC 16-bit DAC) I also think they are locked to either 44.1Khz or 48KHz sample rates?

    The sound quality of Burr Brown chips, although very good, is a bit Subjective.. There are many DAC chips these days that do 24 Bit/192KHz and the difference in brands are up to personal taste.

    Many of the newer Pro-type sound cards will have performance that equals or surpasses anything you can get from off the shelf processors.
    Ours is the age that is proud of machines that think and suspicious of men who try to.

    I am definately open to suggestions on what sound cards would give me a reasonably close or better sound than 210 I am also curious as to if there are any soundcards capable of running a 3way setup

    That's entirely dependent on how you plan on controlling your audio....EQ, XO, etc.

    You will need 7+ outputs most likely, unless you're using an outboard processor, in which case you just need a single output (optical or analog).

    This is all up to you really. Start researching sound cards based on what you will need and make your decisions based on that.
