Mono Recording Muffled (CoolEditPro)

I'm playing around with my new M-Audio AudioBuddy, and I've run into an annoying little problem. I can record just fine in stereo, but as soon as I switch to Mono (for space/simplicity's sake) the recording barely registers. I have to crank it up something like 40 decibels to make it comprehensible, and obviously by then the sound is ruined.
My setup looks like this: microphone to AudioBuddy (with mini-jack stereo cable) to Soundblaster Audigy soundcard through Line-In. I'm recording in CoolEditPro 2.0.
Now, there are also two mini-jack to 1/4" plug adapters in there, one of which is pretty shoddy, but I can't see why that would only cause a problem in Mono.
Anyone have an idea what the problem is?

Jan 16, 2008 01:13 am I just realized -- when I apply a Full Reverb effect, if I leave the "Combine Left and Right Sources" box checked, the same thing happens. The sound gets muted down to an inaudible level even if it was loud and clear before. Uncheck the box, and it's fine.
So it's not a problem with my recording setup. I guess it's some kind of software (or hardware?) issue with how mono sound is being processed.
Jan 16, 2008 10:16 am It sounds like the two channels are out of phase going into the sound card. Perhaps one of the mini-jack to 1/4" plug adapters (the shoddy one?) is defective or wired backwards of the other. Stranger things have happened.
Now, if I'm thinking right, this may also cause any reverb on those channels to be out-of-phase as well, causing the cancellation effect when you combine both channels.
Remember to never mix mono jacks and stereo plugs or vice versa. If you want to split your mono mic signal into two channels, make sure the jack on the adapter is mono, not stereo.
I can't imagine this being an internal hardware or software phase issue.
Jan 16, 2008 01:23 pm Interesting. I'm planning to switch to an XLR cable and take that adapter out of the equation, so maybe that's all I'll need to do. Thanks.
Jan 16, 2008 01:47 pm Herb has it nailed. It really sounds like a phase issue indeed.
