    either if the 2 linked items should work fine for external volume knob...

    You all have lost me now, I do plan on putting in things like steering wheel controls so should I just stick to a software controlled device to avoid confusions??
    wungun and pc pete kind of migrated into a(very interesting) discussion about the best way to control the volume with out introducing distortion into the system-- currently, the jl knob looks like the best, but there is very limited knowledge on how this vol. knob makes the sound louder/quieter, so it is tough to know until someone that knows what their looking at, pulls one apart...

    I'm still suspicious of the JL unit...I'm convinced it's digital.

    One way to find out is to feed it a digital input, S/PDIF for example. If it's analog, then it'll just decrease the digital signal, which won't effect volume at all...just weaken the signal.

    There is also the post-amp volume knobs which I alluded to; the ones you mount in your house to control room volume...
    If they can accept, say 8 inputs and outputs, then I'd be set! Keeping in mind, of course, the power limitations of the knob...

    the biggest issue with the house volume controls is that they are still passive units, and are very likly affecting the sound even more, and power is really limited by the traces on the circuit boards, whereas it is easier to manipulate the low level side while still maintaining signal quality. (maybe a bad example, but how many high quality eq's have you seen that take speaker level inputs?)

    I sent a email to jl asking for more details about how the cl-rlc modifies the signal, i'll post a reply as soon as i get one-- their contact page says that it will take at least 2 days to get a reply.

    The JL cl-rlc unit is just a knob controlling a small 2" x1 " unit , not the JL cleansweep system...there is no digital input....

    They take analog in , and give back analog out....they need car power and remote to operate...I assume there is a small preamp that the knob controls...

    I know there is no digital input....I was just curious to see what would happen if you sent is a RCA digital input.

    jl's respone to the type of processing done by the unit:
    [quote]All signal modification is done in the analog realm, there’s no conversion of the signal.[/quote

    pc pete for the win!

    so it is a remotely adjustable preamp...

    Good job soundman on prying, and good on jl as well for a timely response...

    I use my knobs ( :-) ) more than anything else, it's like every song needs a little bass and treble adjustment...being able to do it instantly without fidling with anything is a major must for me....

    Well, now we know!!

    Isn't having 2 knobs for your mids and tweets kinda redundant? Couldn't you just get away with using a single controller on your tweets, for example, and use your master volume to adjust everything else?
    Or is this to adjust your mids/tweets seperate from your subs as well?
