Start up your Mac by pressing the power button. Hold all 4 buttons down for 10 seconds, then release them. Press Shift-Control-Alt (Option), and, while holding these 4 keys down, press the power button. He organized all the parts inside a 3D-printed. I'd highly recommend this to any Mac Mini user. Macs with a non-removable battery: Shut down your Mac. In conclusion, by rearranging the internals and swapping out the power supply, Nelson was able to reduce the size of the Mac mini enclosure by 78. I actually didn't want to stop listening but I felt I had to email you.īlacker backgrounds, better dynamics and voices are so realistic it's almost scary!Ībsolutely the best I've ever heard from my system. With the fan controller installed, everthing is so much better. There are pins at the end of the power supply.
I've also removed the PRAM battery but still nothing. It's 110V and the model number of that power supply is A1188. It's the original power supply when I bought it brand new. I have a volt meter and I want to try to test the power supply. I've mentioned before that the Weiss is extremely sensitive to power and the incoming signal.īut when the signal is right, absolute magic comes out. Absolutely no power, no light, no fan, no nothing. It's really amazing! I was already quite happy with the JS2, but this really takes it to the next level. Received the MMK and installed it right away tonight.Īnd. Ī sample from one of the many e-mails we receive about the listening results after MMK installation: That circuit eliminates the voltage drop of the DC supply cable and ensures instantaneous voltage regulation right at the computer end regardless of spikes in current demand. The MMK also has a coaxial/SMA jack for connection of a cable to support the pseudo-Kelvin-sense feedback circuit of the UpTone Audio JS-2 choke-filtered LPS. To boot and operate a Mac mini that has been converted with an MMK requires a 12V power supply capable of delivering at least 4.5 amps. The 12V input connector to the MMK is a high quality 5.5mm x 2.5mm DC barrel jack (center pin positive).
