Subject: compression problem
by Big D | 03/03/01 at 19:14:12
I have a Berhringer Composer Pro. When using inserts on the mixing board it is very quiet. When I've run a mic through the compressor imput, output to a preamp and then to a recorder it is quiet. When I run a guitar through the imput, output to an amp it's louder than hell. If I unplug the guitar and cord from the imput it doesn't change so it's not the guitar into the imput but rather the output to the amp. Can anyone explain why this is?
A personal note to those that were aware of my kidney situation. The mass was a cyst and definitely benign. Big relief.

Do you know why? I've registered previous to this and showed up as a member before.

sure, you need to log back in. Unless you check the remember me box on the login screen it will automagically log you out after a while (set by the number in the box). Log back in, click remember me and you're good to go!
And definately good news about the kidney thing!8)
That's a big relief to us all.
Take care,
Dan

:D The input of a guitar amp is high gain, the output of your compressor (line level) will over-load the input of a guitar amp. I am not familiar with that particular model, but when you mentioned running a mic, to Comp, to pre, I suspect that because of the mic level(-60db) and the line level of the compressor at(+4db), then again into a mic pre(-60db), that the compressor was operating as a unity gain amp. Otherwise it certainly would have overloaded the mic pre in the same fashion as the guitar amp. The guitar output is several db higher than a mic. In short, if your compressor is a line level device, then only line level signals should pass thru it. Use a direct box for the guitar to match to the mic level of the board, then process with the inserts. If you want the mic pre sound, the guitar out should be padded ahead of the pre, or turn the guitar volume down.
Hope this helps, and congrats on the good news.

I think i know your problem, if I understand what you said correctly.
If you run your guitar through the unit and then back to your amplifier input, you are getting "double" pre-amped. so to speak. You, technically, should have a "line level in" installed on your guitar amplifier so you don't pre-amp your guitar twice. That way, when the line goes out from your berhinger to your guitar amp, you will be bypassing the early hi-gain stages (which you now don't need) of your guitar amp.

You have to log in again. When you do, check the box that says 'stay logged in' and you will never have to worry about it again.
And yes, as soon as I get the time this is going into the faq :P

I think Puke hit it on the head. If I run the guitar through the compressor to the amp, lot's of noise. If I run it through a preamp to compressor to amp, lot's of noise. The output of the compressor and preamp are much too hot for the guitar amp. Did I get it right? Thanks everyone.

ONe thing I noticed, you said you run your mic into the comp, then the pre. That's backwards, you need to run through the pre first, then the comp to get the mic up to line level so the comp can handle the signal properly.

In fact I did run it from mic, to preamp, to compressor when I did it before. I had forgotten and had misstated the order in my original post. Thanks for straightening that out.::)???

check to see if there is an pad (+4 or -10db)on the
unit.That's what comes to mind first.
