Why am I getting hiss when recording my classical guitar? I am recording through a Sterling Audio ST51 to the Tascam DP004 digital 4 track. I am running through a Phantom Power box, but I am only getting about a half bar of audio signal at the Tascam. This is placing the mic about 2 inches from the soundhole. I am recording in my living room. Any suggestions to boost signal or am I making any obvious errors?
