    Need some explainations in 'Laymen' terms....

    When setting up my crossovers on the amplifier there are a couple of options that I don't know how to setup.

    The ones I don't understand are:

    Twin-T Bass EQ - allows up to 10db boost at 45hz
    HighPass Crossover - 40hz to 400 hz w/ a 24db per octave slope.
    Lowpass Crossover - 40hz to 400hz w/ a 24db per octave slope.


    I understand WHAT the high and low pass are supposed to do....I just don't know what to set them at?

    Any help would be great.

    Whatever sounds best. There is no formula or anything, and it's not something we can answer over the net. You just need to fiddle with it and see what sounds best to your ear in your system.

    I understand that...I just am wondering...if I am hearing too much highs.... should I increase the high pass and decrease the low pass?

    Just looking for some basic guidelines as to which way to turn what for what reason

    As you've stated it allows up to 10dB boost @ 45Hz I'll assume that it's variable, so, that adjustment gives you from 0 to 10dB of bass boost centered @ 45Hz


    And like squeak stated - there's no real formula for settings those crossover points. It'll be all about listener preference. Set it where it sounds best to you. The 24dB/octave slope simply means that the crossover has a fairly steep slope and will sharply attenuate frequencies outside of the limit you set.

    No, I think you're now confusing the crossover points with the input sensitivity, more commonly known as the gain adjustment. If you increase the high pass (I assume by this you're meaning moving the crossover point to a higher frequency) then all you've done is narrowed the frequency range of the source material being sent to those drivers. The same will be true of moving the low-pass cutoff to a lower frequency. You'll narrow the frequency range being sent to your bass drivers.

    If you're hearing 'too much' highs (as in they're too loud to complement the rest of the system well) then there's some adjustment to be made on your gains. BEFORE I GET FLAMED ~~ No, your gains are not a volume control. Have a look at the stickied tutorials on the subject and have a learn


    Hope my ramblings have helped some!

    There really should be a class in school about this stuff!
