[sdiy] Panel wiring

[Elby Designs]

Hi again,

Thanks for the feedback so far.

With regard to wiring panel components back to the main board - assuming a system has a single pcb in the centre of the system rather than a pcb per module - do readers prefer to wire all three pins of a pot or switch (more, of course, if multiple pots or switches) back to associated points on the pcb or daisy-chain common points at the panel and bring only the necessary wires back?

The advantage of daisy-chaining I see would be the great reduction in the cost of cabling required. The disadvantage, the purists would argue, being the potential loss of signal along the chain or induction of noise on to the line.

The disadvantage of wiring all pins on a pot or switch to the pcb would be the much higher wiring cost and substantially larger cable looms. This would, in theory, be offset by improved noise immunity and, presumably, less `drop across the line'.

Audio signals should ideally be screened whilst, presumably, control signals would be okay on hook-up wire? Would you prefer to wire a pot or switch with 2 or more audio pins using a 2- or 3-core screened cable or with individual screened cables?

Best Regards
