Behringer cx3400 crossover

keyser · 28th June 2005, 02:40 PM

I have bi-amped 3-way speakers, crossed with the cx3400. I use the behringer only as a 2-way crossover @ 300 hz. Can I use the low-sum fuction to add an active subwoofer? I don't want to send the complete low-freq signal that now goes to the woofers to the sub in mono, but rather add the sub to take over only the lowest bass. The manual didn't help me any further...

i have examined the crossover further, and it seems what i want to do is indeed impossible

always thought it was possible, and i have already begun building the subwoofer.
Maybe i should (attempt to) build a line-level crossover at about 80 hz?

Is 440Hz crossover too high? If it would work you could use midrange out for the bass and bass out for subwoofer.

i've tried it with the cross over at around 440 hz, but i thought it wasn't really good... I don't fully trust my ears (or maybe brains for that matter LOL). Maybe i should have one of the woofers measured. I've got a spare unit. Maybe i could contact Canton?

Are you using RCA inputs? If so, are you just using a regular RCA adapter or are you using something special? I'm considering this xover again the DCX2496... I'm not sure if I actually need all of the DCX features.

i use a regular rca-xlr conversion cable. it works fuss and hiss free. i must say this is my second cx3400. i had the first returned under warranty. the first was hissy, and it had voltage on the case. got a few shocks from it

they said they had repaired the unit, but they send me a complete new one

waddevva... it works fine now!

Hmm, very interesting. Did you buy your first cx3400 new? How was the warranty process?

keyser · 15th July 2005, 06:41 PM

Yes, bought it new. i just called the store i bought it when i found out it didn't work right. the told me to bring it back to the store, and they'd send it to Behringer Germany. 8 Days later I got the new one (they said it was the fixed unit, but i noticed a slight mark on the left sidepanel was no longer there).
