Noticing that on the Front panel from Carl it is showing XLR In then 4 lines in after. Anyone understand that. Was there a version with only 1 XLR?

The markings on the front panel that you have machined must be edited to the IO arrangement of your build. I have built several variations. What I sent you is just one of those variations. Changing the markings is very easy using the FREE Front Panel Express software that is downloadable from their site.

The standard IO PCB that I ship has two XLR balanced channels and 3 unbalanced channels in and looks like this ...

Yes I agree Carl and I am using the I/O board you have pictured. I have been trying to mod the fpd.file but whenever I click on anything on the front panel it highlights the whole panel detail as if it was dropped in as a pic or something. Trying to figure out how to modify individual labeling. If you know anything about this please let me know.

You need to 'ungroup' the items that you are clicking on as shown in the attached PIC ...

So I have figured out how to change the labeling. Does anyone have a part number for the IEC hole for power input module that will fit this?

If you are using the layout I drew it was a Volex 17252 0 B1 https://canada.newark.com/volex/1725...GEN-SKU-MDC-NF These are fairly generic so others should fit as well.

So I have made mods that I want to the panels with FPD. More questions though I'm assuming most have used DIY audio 1U enclosure. I'm also assuming sent those panels into FPD to be CNC'd. They can print the labeling onto a anodized panel correct?? If all of my assumptions aren't correct someone please inform. Also did people order the backplate with the IEC hole already included?

If you use the fpd file, that is for 2A and for 3 mm rear panel thick. You will find it now @ Mouser
