Hello.
I'm nearly done the zayance power supply for IOaudio U47 microphone. I am stuck with the connections. I have gone through the build thread and was able to finish the mic, the 7 pin cable, using the below pinouts.
Based on photos i've seen, it's very hard to be sure I will be following the correct hookup for my following questions.
Sorry for the trouble, it's a lot of questions, but I want to be sure I have it connected correctly before I take it to a tech to check safety etc.
I used the following pinouts for the microphone and cable:
Audio
1 = A- (gray) (connects to pin 3 of XLR at the power supply)
2 = A+ (white) (to pin 2 of XLR at the PS)
Center pin = audio ground (green) (to pin 1 of XLR)
Power
3 = B- (black [blue in the cable])
4 empty
5 = B+ (red)
Pattern
6 = P (yellow)
I have post some photos that I have questions on. Any help is greatly appreciated.

The IEC power plug... I have soldered already the ground pin to ground on the power supply chassis. Just wondering where the next 2 get wired.
and...
The On off power switch where it gets wired?.
Just not sure how the primary cables (as per the specs sheet, brown, grey, violet and blue are the primary) are connected.
The trim pot... since only two get conected, not sure which of the 3 pins on the pot are wired?
The 3 pin pattern switch... does it matter which order, left middle and right get connected to the pattern switch points on the board?
The XLR connector, where do the 3 points get connected to? The ground i'm sure connects to the center pin 7 on the 7 pin connector?, but does it also connect to the ground on the chassis?
The 7 pin connector, not sure where on the board this will connect?
