Question about Yamaha Aw4416 Aw 4416 Workstation
I get no sound out of the stereo channel when playing my recordings. I only get sound when playing CD's.
the buzzing is indicative of an open ground connection, check the cord by substitution or with an ohm meter, if the cord is good look at the connections to the jack inside the amp ( im guessing you built the amp from a kit). Is this a solid state amplifier? Tube amps have lethal votages and should not be experimented on without knowledge of electronic safety. Also if there is more than one input to the amp try plugging the guitar into another one and see if its still the same.

You have to discover the receive channel for the dtxpress. Try downloading Midiox which is a freeware app that actively displays everything that is happening midiwise in real time.

This symptom indicated that you have a faulty OpAmp IC in the Mix circuit board. The IC's involved is the NJM2068M-D and NJM4558M-D. If I'm not mistaken you have more than 15pcs of this IC's in the circuit board that control the mics inputs. This is a 8-pin IC in D package. You must have at least 2 good IC's spare if you are going to DIY to swap or compare the reading of each IC's in the board.
Also, bad solder joints must be consider in that board and in the power supply feeding this board. Check it first, this is hard to spot, I would advice you to work in the brightest area or used table/portable lamp and magnifying glass. Re-solder as much as possible.
Let me know if you need further assistance.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
