Question about LCDuino to Relay Boards lead length

Postby Garrard301 » December 27th, 2019, 12:41 pm

In a fit of audiophile madness, I have decided that I want to build the Allen Wright RTP3C balanced integrated phono and linestage, and incorporate the LCDuino control system that I have already built, into it.

The idea is that the LCDuino control board remains in one box, and the relay arrays (δ1 and δ2) move to a separate box lower in the rack with an umbilical connecting the two. This is a 4-board (2x δ1 and 2x δ2) setup.

Regarding the 6 core connecting cable between the LCDuino and relays, are there any potential issues with that being 3 - 4 feet in length? The LCDuino already has quite a meaty power transformer behind it (15VA).

Thanks in advance.

As long as you use adequately thick wires (I recommend 22 AWG or better) it should be fine.
