    I've been running a custom eq setting for a while now and it sounds fine but I feel like I'm missing out on something not using the 5band parametric eq. The manual is about as helpful as a kick in the nuts. Can anyone shed any light on what differences there are running a parametric eq compared to a standard eq and perhaps how to go about using it?

    Many thanks,

    Found this pretty good explanation:
    Parametric vs. Graphic Equalizers
    A graphic equalizer has usually fixed frequency and Q value. The layout of a graphic equalizer is the typical sliding controls arranged by frequency. The advantage of a graphic equalizer is that in the way it is laid out, it is easy to see what frequency is being boosted or cut and any person without much experience can adjust it. Since a graphic EQ has fixed frequencies and Q, it has limitations on what it can control.
    A parametric equalizer consists of knobs that are turned to desired levels, have adjustable frequencies and (usually) Q. The advantage of parametric equalizers is a much greater control, since frequencies and Q values can be adjusted. On the other hand, a parametric equalizer is much harder to adjust than a graphic EQ, requiring an experienced person and measuring equipment.

    It's all beyond me. Parametric EQ would seem to be the real deal EQ but because of it's complexity, not very user friendly. Wish they'd just provide some pre-programmed examples you could scroll through to hear the difference.

    I wish they'd provide some examples too. I really don't understand offering up such 'powerful' features without the ability to learn how to use them. I suppose I could just sit in my car for 24hours and fiddle with buttons and settings till it made sense to my ears.

    I'm still enjoying that stealth sub you sold me a year or so back. Worth every penny mate.

    Glad to hear it, thanks.
    I think the problem with Alpine is they've got so obsessed with award winning high end systems that use a laptop and microphones to analyse and optimise the sound for the driver that they feel all these features should be included in all their head units not realising that without the specialist equipment to set them up properly they're pretty redundant.
    They've forgotton to include the idiot menu with basic controls and functions that protect the average user from the serious stuff. Still include it but have it buried in the device with an admin password so someone like me doesn't happen upon it and **** it all up.
    Simple Bass and Treble controls would be nice, I don't want to have to go into a parametric EQ sub menu just to boost the bass a tad on a certain track and certainly don't want to face complicated decisions about Q factor and exact frequency while I'm driving.
    This was the only reason I moved away from Alpine HU's, I still have an old skool one in the quattro, but went with Blaupunkt on the TDi, primarily for integrated DAB but also as it's very easy to use.

    I reckon, on the weight of this conversation, that the paramentric EQ isn't really gonna be worth my time.
    I might play with it one day, if I'm really bored, but I'd probably do better to get my infinity Kappa components installed. they'll probably make far more difference than the EQ. If only it'd stop bloody raining!

    Actually Andy, I'm sure I saw a pdf template you put together for creating MDF spacers for Kappa's. Does this exist anywhere on here? I've done a search and can't find it anywhere. :(

    I still have them, PM me your email address and I'll mail them over. Still haven't found a photobbucket type site where you can host PDF's.
