what brand/model is the umbilical connector? i'm in the market for some for connecting a central power supply to 4 balanced amp channels in 2 'mono 2 way' power amps and i've been looking at the ITC cannons and amphenols, but they arent cheap, even though i lust after them

amphenols

they are not cheap and only come in two major configs.. 3+1 and 6+1 (they always mark one pin as ground, but that pins is the same size as the other ones, so you can use it like any other pin)

the 3+1 is screwed based and 6+1 is solder based..

I use both and they are built the same way, have the same cut out.. so I don't have to worry about having two different templates

I thought they might be. the amphenols arent too bad, except for the ones i'm looking at, the ones with the really high current radsok pins and army green cadmium plate. the Cannons are just plain awesome!!. see i'm looking at the high current 10 pin (8 high current and 2 lower current for LEDs softstart, control etc) and i need 2 umbilicals, one for each 2 channel (4 phase) amp box. so i'm looking at roughly 350-400 plus wire. the other option is powercons and speakons but use more of them, but they arent nearly as cool

large lemo high current umbilicals? yeah me too, but i dont even consider those as i could buy a small car with the price i'd pay for using those in this project (300 each), i use lemos for all my low level signal and headphone connections though, superb!!

so I bought some amphenols that were used by the US military in their tanks.. and I had to sign like multiple documents saying I won't export them.. they were silver plated radsok pins and super high current capable.. I am saving those for my burning amp builds..

since this is "only" a ck2iii i figure the plastic amphenols is "good enough"

i was going to use speakon etc.. but then too many people going that route and i don't want people trying to connect their speakers to my amp's power input or worst.. the power supply output!

yep, those are the ones, you can actually buy them for export, perhaps not your exact model, but that sounds exactly like the ones i'm looking at
