I am trying to repair a Yamaha EMX312SC Mixer which suddenly lost all bass/ low end whilst in use. It had two speakers plugged into it at the time and continued to output the mids and highs so I have assumed that it is the mixer and not the speakers at fault. So far I have dissembled the mixer following the attached service guide (though have not dissembled the power supply half of the mixer yet) and have not seen any obvious faults/ blown components etc.
Does anyone have a similar experience ? Any ideas? Also in the service guide are several circuit diagrams. If someone could identify the circuitry responsible for the low end audio that would be very kind because I have very little experience with audio circuity.
Thanks in advance,
