Hey folks,

Anyone know how the LED should be oriented in the Sigma 22 PCB? I can't seem to find any indication for polarity.

LED + lead connects to R16.

Thanks MoodySteve! That's what I guessed looking at the schematic but wanted to make sure.

Another question now that I've made some progress:

Is there a standard way of splitting the umbilical coming in from the sigma into three different wires for the three separate B22 boards that I'll be using? I was just going to solder and shrink tube them together but that seems kinda not so elegant.

Some people like using multiple powercon connectors:
Redco Audio

Some people like using DIN Connectors

Some others like using XLR. A six pin should be fine.

Cheers!

Amphenol "Ecomate" Series is another reasonably priced alternative.
Available at Mouser. You could use the 6+PE ones, I'm using 2(4 jacks and 4 cable connectors) to get power to 4 amp boards, then using the 1 extra terminal pic for the HP ground return to the PS for unbalanced cans.
