A Kontrapunt B has an output of about 500uV at 5cm/s.
Records are modulated to up to 15dB above this level, that makes
48dB of gain in the Dino puts this at 700mV.
The UA-5's input sensitivity for 0dBFS is -10dBu, or about 250mV...
But if you look at the back panel of the UA there should be a knob labelled 'input volume'. That should do it, not?
If not then set the Dino back up for 62dB gain (what the Ortofon
needs) and insert a variable attenuator between Dino and UA.
