Hello,

I have just bought 2 DB Technologies Twin 128 active speakers and i happen to interfere some problems. I would really appreciate if i would get some proper feedback and help. Thank You.

Firstly, i connected the speakers to the main out of my mixer (http://www.behringer.com/802/index.cfm?lang=eng). One speaker on the left output and one on the right output via XLR ends plugged in the speakers and jacks plugged in the mixer. The microphone works fine. the voice sounds ok, also if we play some music through they work fine. but when i plugged the guitar amp in the mixer with the guitar connected, i found out that the distortion the drive gets lots and lots of gain, like it's not the sound from amp anymore, it's like a digital cheap distortion. i don't know what's the problem.. maybe the cables .. or ... i really don't know.

I am waiting forward to replies.
Thank you very much
Best Regards

What amp are you using, and what jack are you using on it to go into the mixer?
AMP:
5150 combo
GSP1101 + Tech 21 PE60

GUITARS:
ESP LTD M-255 w/ SD Full Shred
Kramer Vanguard w/ JE-1000 active preamp
Douglas WF-150sn w/ GFS "Hot Lead" set

EFFECTS:
Bos SD-1 (boost)
AMT DT-2

I plugged the amp from headphones to the mixer via jack cable, and the guitar plugged in the input of amp. It's a cheap Frontman 15, but the amp itself sounds good as compared to the speakers high gain.

The headphone jack will work fine for this.

Ok, what you are hearing is "clipping". This happens when the signal is too hot for the mixer to handle. So what you'll want to do is turn down the volume of the amp and use the monitors you have plugged into the mixer as your main speakers.

On your mixer, right above the "Main Mix" knob, there is a signal meter. Lower the amp's volume until the lights are in the yellow. Once they hit red, you'll get the nasty SS clipping.

-20 db button, that should do the trick
-------------------------------------------------
- Fender Strat (1988, Japan)
- Epiphone Les Paul (2008, Korea,)
- Epiphone Sheraton (1988, Korea)
- Morgan WG20GEN (2003, Norway)
and some stuff non-used stuff for sale/trade in the Netherlands

no it's really not the clipping. even with the amp at low studying levels it's like i have that so very cheap high gain distortion without any bass without any mids only huge gain and highs. The thing is that nothing's clipping. not even the first green led.

Thanks.

Given that it is not clipping the signal, it must just be your amp. It's not exactly the best out there, so it will suffer a bit tone-wise. Also, studio monitors are designed to produce as neutral a sound as possible. Where-as guitar speakers are "voiced" to accentuate the mid-range of the signal. So what you're hearing is what the preamp of your amp really sounds like. So, my advice is to just cut back the gain on the amp a bit and to eq the channel on the mixer to add in some of the lost mids and bass.

the thing is that i tried a multi FX processor instead of the amp.. and the sound was the same, but as far as i know.. that's how a processor(cheap is mine) it usually sounds through mixer. , and another thing is that i tried the exact same setting but with some very old hand made speakers in the main outs of the mix. and the drive was ok.. you could see the lack of the quality but the thing is that the sound was quite ok, and not almost as a very high gain digital distortion.

my conclusion is that maybe the preamp of my frontman 15 is not so good enough to work with this speakers, but again could it be from the speakers? , but i doubt a bit. cause they are already new, and quite powerfull.

In any case if i try some settings.. it's obvious that i cannot lose the high gain. I had tried some settings on the eq of the mix but , you can clearly see that something is not ok, in you cannot mend it, just to change something.

If the speakers are brand new, they will take some time to break in. New speakers always sound a little harsh, so give it a few days.
