Axiom Home Page Forums General Discussion Technical Questions EP 350 Stand-by Problem

I agree with Dave, when I owned a 350, I kept my receiver sub trim level(dB) at 0dB, which put my subwoofer volume/gain knob at around 11-12 o'clock when calibrated with an spl meter at 75dB. If you have the receiver level to low, the sub may be going into sleep mode.
