Crew,
Just purchased a nice quality Channel Strip & Mic (Focusrite TwinTrak Pro & Groove Tubes GT55.) Broke them out for the first time yesterday for a vocal session at a friends project studio...& I noticed that, even though @ normal gain & impedance settings, everything sounded very, very quiet, I still had 35dB of noise on the peak level meters [in the track in the DAW (SONAR)] !
I'm going to listen very closely to just those vocal takes tonight, after I upload into my DAW from the external drive...but, that doesn't sound normal, right?
Even during the session, I would be monitoring that queued track in the phones prior to recording...& there would be absolute silence (even though the meter was hovering around -34 to -40dB); & then when the vocalist would speak or rehearse, the levels would be normal.
I had my variable input impedance on the pre set to 1.6kohms for the GT55's output impedance of 200ohms (which is within the normal 10X range...& which sounded just fine for overall frequency response.) The gain on the pre was set to about +25 to +30dB (just a little beyond the center of the range.)
Can't figure out what's going on.
Thanks,
mark4man

I don't know if this is the problem, but was the air conditionning on while you worked? The "ghost" you're talking about might be air flowing in the room at a rate of a few Hertz (proper studio air conditionning design, so that you don't hear it). It is picked up by the mike and it registers on the meter...
The simple cure is to use a high pass filter or turn of the ventilation...
Hope this helps,
T.
