Equaliser module

Discussion in 'Pro Audio' started by Dirk Bruere at Neopax, Dec 6, 2005.

  1. Does anyone do an (third octave) equaliser module? That is, a box that is
    programmable from a PC but just with an input and output?

    Rane and Electro-Voice do at least, although their boxes can do some other
    stuff as well. I'd bet Peavey's Architectural Acoustics folks do as well.
    The notion is very popular for installed sound applications; you program
    the EQ, then disconnect the PC and now nobody can futz with it.

  3. That's the type of thing.
    However, I was thinking about something that would sit in the palm of my hand,
    not a rack.

  4. OK if it's capable of feeding 10 kilowatt-hours to the power grid, too?

  5. However, I was thinking about something that would sit in the palm of my hand,
    Why? You aren't going to be holding it in your hand while using it,
    especially since the idea is that it would have no controls...

    Compact would be cute, but a box works.

    Behringer has some 16-40 band parametrics that are said to
    be programmable from a PC, and provide equal or better
    equalization flexibility to a 1/3 octave.

    DSP 1124

  7. The 'why' is that it will fit into a speaker housing to balance multiple speakers.

    OH! You don't want a third-octave equalizer, you want a programmable
    crossover! That's a different thing altogether. There's some outfit
    that advertises in the back of AudioXPress with something like that.

  9. I've got the one but want the other to smooth the response across the spectrum.

    And all your response problems are all exactly a third-octave wide and
    centered precisely on third-octave bands?

    If you have response problems that are inherent to the speaker (and are
    therefore actual frequency response problems and not side-effects of
    time domain problems), equalization can help. But a third-octave equalizer
    is apt to do more harm than good.

    But this is why most of those digital crossover modules include a couple
    additional filters that you can use for this sort of thing. You can use
    them just like a parametric to flatten the response. Just make sure to
    make some measurements at different positions to make sure that it really
    _is_ flattening the response and you aren't trying to compensate for
    something else.

  11. We're doing all that using Soundweb and frequency analysis in the studio.
    However, sticking a soundweb into each speaker box is not practical, either from
    a cost or size POV.

    I'd also like far better res than third octave, which is why I posted another Q
    here in a different thread on equalisers.

    Okay, so what you REALLY want is a configurable filter box that you can
    use both as a crossover and for narrowband speaker equalization, in a
    small cabinet that can be mounted inside a speaker, with remote
    computer control?

    Is that it? Why didn't you just SAY so?

    If so, look at the Signal Wizard II from Saelig. Probably there is some
    propaganda at saelig.com.

  14. Could use that, but it's a bit pricy.
    I now think I can get what I need using the DSP in the poweramp I'm using in a
    slightly unconventional manner.
