Hey so i am makin a home recording studio. Its gonna be recorded onto a Mac G5 threw a Firewire or USB mixer. But since i need 8 XLR inputs on my mixer i had a question. I already have a powedmixer that i can plug my drum mics into. Can i take a 1/4 Main Output from the powered mixer and instead buy like a 8 channel mixer? or will the signal come in to hot?
