Don't suppose anyone happens to have a service manual for a Pioneer
DDJ-SZ ? Having some difficulty getting one, even through the Pioneer
route. It looks as though the owner has managed to **** one leg of the
XLR balanced output on both channels. Once I had got inside it, I found
a surface mount something in series with the dead leg on each XLR. There
is signal one side, but not the other. They are designated P701 on one
channel, and P702 on the other, so in keeping with other Pioneer items,
I'm guessing that to be "Protector", except it doesn't look like the
typical surface mount fuses that Pioneer use in their other DJ units,
which are usually very low profile and have a letter on the top of them
to indicate value.

This device is black plastic and about 2 x 2 x 3 mm. Standard sm cap or
resistor connections at each end. Stamped very clearly on the top is
"10". But 10 what ? Could even be an inductor I guess, 10 uH maybe, but
I would then have expected its designator to be "L" ??

The other thing that puzzles me slightly is why you would have anything
in series with one leg and not the other on a 'balanced' output.
Interestingly though, I had a look at the schematic for the DJM 800 I
think it was, and it shows a 0.5A fuse - proper fuse symbol not a
rectangular box 'protector' symbol - in just one leg of the XLR again
... Thoughts anyone ?

So is there "half" a signal on one pin and its other " half" present
prior to the SM blob?
