If you mean this model, going by the text it's manual:

Top panel bias testing terminal with bias adjustment controls plus EZ-biasing.
I would love to hear the power amp version of that integrated:
http://www.jolida.com/product/powerpre/jd502p For their unique market position you'd think there'd be tons of user reports for these amps. There is, but all the reports I found were for ancient vintages. Jolida changes/updates their line frequently, not reflected in the nomenclature, diminishing value in older model reports if not making them totally misleading. Current models seem to have a lot of modern upgrades.
For all the fifty or so Jolida user reports I read, maybe two strong negatives for reliability. But they were for 90s era. I believe QC is dramatically improved since then. The rest of the users either raved or liked them a lot.
My friend's Jolida Music Envoy mono blocs sounded great.
IIRC the smaller EL EIGHTY four integrated costs only peanuts, about $870.
