hello,

ive been recording with both the SM57 and Sennheiser e906. They both work great by themselves. But when i record with both of them together I get heaps of fuzzy noise or no sound coming out of one of the tracks. I was just wondering if anyone can help?

Thanks :)
 
Just what is on the back end of this recording chain? Both appear to be dynamic mics which require a decent preamp (each) to get enough clean gain. Otherwise high noise would be expected. If you're somehow trying to mix the two without the aid of 2x microphone preamp channels, a mixing board, or at least a headphone preamp, that could also account for the less than expected results. Not to mention potentially harmful to the mics. Basically not enough information here.

Two mics. Unexpected results. Isn't enough to go on. Kind of like saying that you can't drive. It could be anything. The driver, the vehicle, or the society.
 
well I am running each microphone into two seperate inputs into a profire 2626 and recording them as two seperate tracks. If i record them individually they sound fine, but when they are recorded together one of the tracks just sounds like white noise or is just silent then it will cut in and sound normal for a few seconds. Im not sure if it could be something to do with my mic placement or the settings on the profire or even in pro tools?

Thanks for the reply
 
Have you tried troubleshooting it? Swapping mics keeping everything else the same, cables, channels, ... Could be a bad cable. Could be a bad channel on the interface. Buzz, white noise, and other extremes shouldn't be a function of the mic or even using two mics. It could just be the software. Try audacity, or one of the many other options. Lots of things that it could be. Not that we'll know until you/we change one thing and that one thing makes the difference. Most likely a bad cable IMO. Could be a bad connector on the interface (or mic / or cable). Could be anything really. Try to keep your cable(s) from crossing each other or other equipment. Try it with the lights on and lights off. Buzz / hum is normally some sort of grounding issue. Could be the power supply, could be the cable, could be anything.
 
I never even thought about the cables crossing eachother! That could be why, do you think that I am getting some sort of interference between the mics then? But its weird because I can hear bother mics in my head phones perfectly before I hit record, i dont hear anything wrong when recording but as soon as I hit play back I get the buzzing. Also if I arm two tracks with just the one mic I get the same thing so maybe its a problem with pro tools?
 
It'd have to be pretty thin / cheap cables or just unbalanced to get interference. The cable to the headphones is more likely to be susceptible. But the mic cables are more likely to run near / around other things like a mini fridge or a display or other things that can impart an influence.

If your monitoring doesn't show it at the time of capture, then it's probably the capture software IMO. Not that it isn't other things, but with software it's fairly easy to rule out since there's so many different apps and OSs that perform basically the same task. See if audacity has the same issue. It could also be the driver for the interface / soundcard. And could be anything really, until you find that one thing that fixes it.
