I bought the Behringer A800 for my passive Desktop speakers. Its awesome.
Im working on a budget, so what I got my hands on for free is a big old Yamaha passive sub and a small ****** active sub.


I could transform the old sub to an active one using the old ones sub board and then connect it to my PC and its output to the a800.
I could transform it and connect it directly to my PC, using an extra programme to give different signal outputs via the jacks.
I could try to modify an XLR cable and directly connect the old passive sub to the a800. Could that work out?

Can I connect a passive subwoofer with the Behringer a800 via its XLR-output while the loudspeakers are connected to the amp via its regular output?

The only place you could connect a passive sub in at the output. (speaker output at the A800)

The Ch A & B connections are for left and right input connections. There are two different types of connectors for each channel. So when using it in a pro application there is flexibility in the connection used.

The A & B connections at the output are simply 2 more different types of connectors for pro applications.

So I cant connect a passive sub and passive speakers to the amp at the same time, right?

Should I connect the PC to the active sub to the amp or the PC to the amp and the active sub at the same time via the different mobo audio jacks?

What motherboard are you using?

EDIT:
Is the blue output from the motherboard rear channels or line in?


OK. We are talking about a active and a passive sub. (Do you have 2 subs. One active and one passive?)
Which one do you want to talk about?
I suggest if you have 2 different amplifiers then use the passive sub connected to one amplifier and the speakers connected to the other amplifier.
Then split the green 3.5mm output from the motherboard into two connectors and then connect to the amplifiers using the RCA connectors.

I could do that, yes. Just need to buy a 3,5 splitter for that. Thats the best quality solution? Better than having the sub-amp in between? (in that case I need to buy a RCA cable)

Which sub woofer sounds better and goes better for you? Does the active sub have RCA connectors? The passive sub has speakers wire connectors of course. Determine which sub woofer is preferred and then if you need to clarify the connections we can do that. But you need to decide which one.

the passive one is bigger and better.

The splitting solution seems the easyest, but doesent that mean the bass frequencies are played twice?

Yes, the bass will be played twice if you use the passive sub woofer and 2 amplifiers. Try it and see how you like it. Then try the other sub woofer if you need to.
