    4430/4435-specific card for JBL 5235 or 5243A crossover is 52-5130.

    You'll need two cards if you're hell bent on doing this. I haven't had the luxury of
    comparing 4435's in biamp mode vs. passive crossover, but others here have
    formed an opinion or two.

    4430 & 4435

    The primary problem is that the 5235A and 5235 are professional grade electronics and they sound like it. Several forum members have now had the opportunity to use the 5234A and 5235, have experience in their use and are qualified to comment on them.

    For home hi-fi use a line level passive high pass is desired. I've been over this several times before on this forum and I'm not inclined to go over it again. Instead, I'll let those who wish to malign the 5234A and 5235 continue to do so.

    ooooh! Can I use THAT one?! (..it really works with my moronic typo name.)

    You made a wise choice- the cat is just too cool.

    First excuse me for my poor language/
    I have my self an other question for 4430/4435 users. The 4435 can be use with their passive crossover, or can be use for bi -amp when the back switch is activated (fc : 1000hz). But is it possible to use two amps at the same with the internal crossover (so in passive mode) ?
    Does anyone have the user manual ? like this It would confirmed myself all the configuration I can test with my pretty studio monitors.

    Best regards Stephane

    Network does not appear to be designed to run dual amps without bi-amping.
    I do not wish to suggest modifications (falls into DIY, as far as I'm concerned).

    You must modify the crossovers to accomplish that. I added the option (and use it that way, mostly) in building my own N3134 crossovers:
