Popping/Buzzing When Recording Guitar Through Audiogram6 Interface in Logic Pro

Hi there,


Long time reader, first time post :)

I have recently bought an Imac G5 and am running Logic Pro 9. I am trying to record my acoustic electric guitar through my Yamaha Audiogram6 USB Interface. As soon as I plug the guitar in Via a 1/4" and XLR into the interface through the mic/instrument port, it gives off this popping feedback sound. The strange thing is, I can record my MXL condensor microphone through the same port with no popping or feedback problems at all (obviously it has phantom power though).

I have already tried to eliminate any external devices (such as turning the monitors off, moving the guitar further away from the computer/mixing desk but still get the same popping)

Even if I have the compression and gain on the interface set to 0, as soon as I turn the level 1 up and the master up, the popping occurs. I dont think it is a grounding issue as I have tried to move the guitar and interface on different surfaces and even when I touch the base of the XLR chord it makes no difference. The popping sound is generally consistent and sounds like a heart beat (boom boom)

I dont think its a Logic problem because the same popping happens when trying to record in Cubase. I think it must be either the interface, pickup on the acoustic electric or the XLR chord (even though it was sold as balanced) I AM STUCK!


I am frustrated and need help! Please give me some suggestions...


Cheers Lochie
 
still cant record without this 'pop pop' sound every few seconds. Any suggestions??
 
Try it with an unbalanced guitar cable from the guitar to the Yamaha. The guy that sold you a balanced XLR> TRS cable to plug the guitar should have his ass removed.

All you need is a regular guitar cable 1/4" TR to 1/4" TR configuration.
 
Yup. The cable is the prime suspect. The output of a guitar is an unbalanced TS connector. Chances are that something is "almost" making contact when the TRS is plugged in and popping/buzzing every time it makes then loses a connection.

In the longer term, I'd suggest a DI box for recording direct though.
