Hi.

I wondered if it is possible to have kx LFE using a standalone amp like this one:

http://www.thomann.de/gb/behringer_a...ioendstufe.htm

What I mean is , to be able to redirect a certain bass frequency range to a subwoofer using that amp and kx project. And as well certain frequency range to highs-middles frequency speakers.

From what I see, that amp has 2 inputs but I don't imagine it would be able to output for example what comes from input1 to output1 and whats comes from input2 to output2.

kxproject LFE to work, does it favors selfpowered speakers and subwoofers, where each has own dedicated sound input connector?

That is exactly what I would expect it to do... I would expect anything else to be optional extended functionality.
Have you looked at the user manual?
According to the manual it has a switch to switch between a bridged mono mode and a stereo mode, and of course in stereo mode, the 2 channels are independent.

i.e. (from the manual)

The amp only has 2 channels, so I am not sure what you intend to do with the mids and highs (edit:for a center speaker maybe? i.e. you are not going to get stereo output of the mids and highs, if one of the inputs/outputs is used for the lows)....

I am not sure what you are asking... The outputs are unbalanced line level outputs.

Mids and highs for stereo speakers, and bass for subwoofer via kx project 4rth order crossover.

Independent channels, interesting.

That amp is basically two mono amps in one chassis...... so what you want to do for the bass would work, but not for the highs and mids as they would not be stereo. You are better off getting a mono amp and a stereo amp, OR a stereo amp and a powered woofer, to do what you are planning.

KX and a compatible card are up to the task.

That would be 3 channels, so you could not do that with that amp.
edit: oops, Tyrsonswood beat me to it

Thank you Russ and Tyrsonswood.

I spoke with a big shop that sells audio gear, and they told me, to use a pc with an amp is needed a Tone control circuit or Boost/Cut controller hardware.

Tone control circuit - Wikipedia, the free encyclopedia

Please what is this about? Please what processing does the pc sound needs to be outputed by an amp? A cut of audio ranges that are not compatible with the speakers used?

Whatever is needed, can it be done via kx project?

They as well told me that this is not needed when you use self-powered speakers and self-powered sub.

First.... Stay away from audio shops.... especially high end ones.

Now, what they are probably hinting at, without knowing what they are talking about is this. A standalone amp, like you linked to has no "pre-amp" it is just a power amp. Many of them may not even have a volume control (although I think the one you linked to does have volume control I believe) A Pre-amp has your tone controls, many times input and output volume controls, maybe some VU meters, impedance matching for various types of inputs, etc. The guys at the audio shop are thinking a computer has none of this capability..... (many computers don't, or it's very limited)

Some of this capability you do have with KX controlling your sound card so it would be redundant, but may not be as convenient as grabbing a knob.... much of that depends on what you are doing and what capabilities you want/need. I like knobs, personally, and run a lot of outboard gear besides using KX. Other guys don't and find using the mouse to tweak a tone or volume the only way to go...... When using both, which is what I do really, you need to know where "what you hear" is being effected, especially when recording. (not so much for general listening) The redundancy can kill you (not literally) if you aren't careful...... Spending hours getting your KX EQ's set perfectly is wasted time when you just grab that tone knob and give it a twist, or forget that you had done that yesterday and didn't return it to flat.

A "self powered speaker" is nothing more than a power amp with a pre-amp, many times with a rudimentary tone control, built into a speaker box.

Just from following all your posts and trying to help were I can I see a few things....

First, I have no idea what you are trying to achieve over all. (no offence, I just don't think you put it out there) Music recording studio, general listening room for music, Just good sound from your computer in your bedroom??? If you did say this somewhere, I missed it, sorry

Second, it seems you may be trying to over think some of this stuff. (again, no offence intended) Several of us have said the same thing, "It's what sounds good to you" (or something similar) When it comes down to pleasing your ears don't get too overly technical (The main reason to stay out of audio shops.... )
