I am having an issue with a Proto E7B unit that has a QSI decoder in it that is not putting out any sound.
Recently a dear friend and member of our club passed away and his widow graciously donated some of his equipment to the club. I had volunteered to go ahead and program them on my NCE at home (a different one was being stubborn on Digitrax) I programmed (one at a time) both the E7A and the E7B to the same address to run together. Both units are QSI equipped. I have sound and everything fine on the A. The B on the other hand was silent- so I figured they just relied on the A for the sound. Then I popped the top and found hmm- this thing has speakers and a QSI decoder- but no sound. I figured the easiest thing was to do a reset with the reed switch (it must have worked as it reset to address 3) but still no sound. It runs find and responds to commands but doesn’t have sound. I tried the f8 too no difference. Any thoughts- is there a CV that is set to default off? Skimmed the QSI manual on it online but found nothing (could have missed it that thing is the size of an encyclopedia) Any thoughts?
