@Gasp3621 will do and report back; still lo level gain at 12 o'clock should be "ok" and not give me -10db....
will try that button at 10 o'clock and see if i can get a calibarted level of -6.5 or - 7.5db....
The Gemini II comes with a neurtalink cable that connects to the speaker terminals on your amp and to the high gain connection on the back of the sub. For music only this is the recommended way to run it (although experimentation is advised for every user). From what most people say on this forum, set the high gain to a point where you can hear the bass sort of coming from the sub and then turn down a notch but again experimenting is your friendHi. New member, though I am sure over the years I have read stuff on here.
Anyway, I was looking at the Gemini 2 and I found this thread.. 10 years this thread has been going!!
After 3 decades of owning hi-fi I have decided maybe I'd like to experiment with a sub. for my small living room 12ft by 10ft. My set up in that room is Arcam Alpha 10 amp, Mission M74 floorstanding speakers.. I have a 50in plasma also, and I like decent sound for movies, but primarily I am a 2 channel music guy.. well soon to be 2 channels and a sub... movies and music I prefer simple.. I just want the sub for a bit more thump. I will not be adding more speakers.
My speakers are aggressively toed in about 40 degrees along the longest wall and so fire across the narrowest length of the room.. which after much messing seemed to work best.
Questions.. do I use the low level or high level inputs? My amp has preout and power in phonos that are not connected (no bridge necessary). If high level do I put these on SP1 or SP2? If I put them on SP2 doees that mean I can disconnect the sub when not needed by switching off SP2? Is it correct you should turn the sub off before you turn the amp off? Will connecting to SP1 or SP2 degrade my sound in anyway or cause stress to the amp i.e. effect impedance?
Am I right in thinking the Gemini has a toroidal supply and is class A/B?
Am I right in thinking that metal plate with the knobs and display on etc likely doubles as a heatsink? Obviously I have noticed higher models in the range have additional finned heatsinking attached..
Anyone look inside? What eletrolytic caps do BK use? I found a hazy picture of someone disassembling a gemini and it looks like they did or do use Samwha for the main filter caps.. which is good.. I'd prefer to see Japanese Rubycon, Nichicon, Panasonic.. but the Arcam Alphas used Aerovox, Rubycon, Taicon, Samwha.. and the South Korean Samwha appear to have very good longevity... I just don't trust Chinese electrolytics. Not yet anyway.
What kind of settings am I likely to probably settle with?
Thank you

You’re right: the Gemini II uses a toroidal power supply and is good old class AB. The big caps are those green and yellow Samwha you’ve mentioned.
BK seems to think that an exterior heatsink is not needed for this 150w amplifier but I would disagree, as it can get quite hot if pushed a bit.
Since this subwoofer uses a sealed housing, it is fast enough to keep up with music but doesn’t go very low.
It helped with my Quad Z1s but these are fairly bass light and have a 6” inch woofer, only.
Try to get the subwoofer in the corner of the room and play with the phase control. It should have enough shove in your room.
