I have a digital copy if you're interested
Thanks

it is at the settings

It does does this because At least one of the amp output may have gone bad carefully look inside front blown capacitors they usually are rounded on top instead of flat the way they usually are. replace with same mico ferret uf but a higher voltage rating for example a 16v should be upgraded to a 24v and so on this helps older units run better. Also remember there is soldering involved here and dc capacitors have polarity + and - so don't mix them up when replacing. good luck

Possible manual, for SR-96 (but doesn't specify SR-96U). https://www.manualslib.com/manual/1010603/Marantz-Sr-96.html Possible service manual, that include nameSR-96U) http://www.vintageshifi.com/repertoire-pdf/pdf/telecharge.php?pdf=Marantz-SR-96-Service-Manual.pdf

You likely already have a user manual but just in case...

This will be a setting issue possibly the signal level for aux 1. Or the level on the phone itself.
