problems with mixer? - fixed...thanks!

What's the mixer make and model, Janet?

Hi Janet,
 It sounds like you have connected your new monitors and new monitor cables to your mixer. The left connection from the mixer to monitor is much louder than the right connection.  I'm guessing what is happening here is that you are just getting some bleed through to the right side which seems to be confirmed by the fact that you are getting the same results from your headphones. When you switched the cables, I am assuming that the Left Monitor is now the loud one, which would rule out one of the monitors or cables being bad.
 Did both channels work fine in your headphones prior to adding the monitors? The problem could be with your inputs. Check to make sure you have good L and R inputs. Check to make sure you are monitoring in stereo or you have signals panned to both L and R.

It's the cable or the jack that the cable plugs in to.

Is it one of these?

XLR. Hmm. Ooh. That's not good. You really gotta try to kill one of those cables.

It could be a few things causing the buzz.

I'm still leaning toward the cable that connects your PC to your Mixer though.

I would disconnect the mixer from the PC on the mixer end of the cable and see if you still hear the buzz.

If it goes away then you know it's the cable between the mixer and the PC or something inside your PC which isn't good.

Did I say XLR cable? Sorry...it's a 1/4", but on the mixer side, it connects to an RCA adapter. Anyway, I just tried another cable and it does the same thing. (major buzz when I activate the cd/tape to mix button.) Otherwise, everything's working fine. What does that button do? And in the meantime, does that mean my soundcard is going bad? It's only a couple years old (I think.)

Yes, that's the familiar picture. Thanks. :) I do have them connected that way. So I guess I just don't need to engage that other button. I suppose I never had that effect before because no monitors were hooked up. OK, now to listen to some good CD's to hear what music's SUPPOSED to sound like and see if I can get my mixes anywhere near that. :) Thanks again. I almost emailed you, cause I knew you know what I have (and how little I know!), but I figured you'd see this when you got a chance. :)

That's a good question, Jonbouy.
For the most part, it's a matter of convenience. If your monitors are where they are supposed to be, they are just out of reach, and it's nice to have that master volume control on the desk.
In my case, it's necessity,as my power amp has separate controls for left and right outs (I have passive monitors). I needed a master volume control on the desk, as it's just not practical to mess with the amp.
There are two significant differences between the otherwise similar 502 and 802.
The line level CTRL ROOM OUT, and phantom power, present on the 802, but not the 502.
With the 502, going directly from the sound card to the monitors is more realistic, and may be your only option.
With the 802, having that volume control front and center is a big plus.
