Hi! 🙂
***
1) I am attempting to “piggy back” a (smaller) IcePower 500A off a (larger) IcePower 1000ASP module, as is described in the Documentation of both units.
2) The (smaller) IcePower 500A requires both an +/- 80VDC “amp power input” and a +/- 12.8VDC “signal power input”, and the (larger) IcePower 1000ASP provides both of these as Pinouts. So far, so good…
3) However: I am currently tapping off of the + and - 12.8VDC coming from the (larger) IcePower 1000ASP to power a few LED’s.
4) This leads to my question: will these LEDs create noise on the DC power supply that would adversely affect the sound quality of the thing being powered (the “signal section” of the smaller IcePower 500A)?
5) Page 4 of the the IcePower 500A Documentation shows a “Control/Protection” module in the Block Diagram after the “signal power supply” so my sense is that this is a non-issue but I wanted to verify that.

LED's are just a forward biased diode- pure DC. There is no switching noise, and the power draw is tiny so there should be no problem at all.
