Attempting to repurpose the back panel from previous build by trying to overlay a layout using the larger previous holes.<\/figcaption><\/figure>\n\n\n\n

Not quite the layout I wanted. Filled some extra holes with screws for show. Going to try a full isolation switch between RCA and XLR inputs.<\/p>\n\n\n\n

My first from scratch PCB design to actual board \ud83d\ude42 Tried to make the HV rails wider than the others, and produce with 2oz copper.<\/figcaption><\/figure>\n\n\n\n

Broke a connector on the ribbon cable whilst adding the male extender, so 5 channel testing out of the window today. Parts ordered. Second attempt resulted in pins 9\/10 shorting. Fortunately, they were \/FAULT and GND, so no damage done.<\/figcaption><\/figure>\n\n\n\n

Instead of fixed length cables and trying to add a male extender etc, opted to just use some unterminated funky cable and use a vice. Tested each plug on the cable. All working now.<\/p>\n\n\n\n

Wiring all in, will need a tidy up. Tested all channels with both RCA and XLR via connector, everything working. Time to move it to the other system.<\/p>\n\n\n\n

A few hours running in on 5 channels, not getting warm yet.<\/p>\n\n\n\n
