I am adding a Relay G30 receiver to my floorboard. I would like to use one of the commonly available 10'-20' low-voltage extension cords to run power from the G30 receiver on my floorboard to its too-short factory-supplied power cord, which will be plugged into a power conditioner behind my amp. Two questions regarding this setup:
1. Is there any problem with, or wiring specifications required for, using a low-voltage power cord extension with the Relay receiver's power supply transformer and cord? and,
2. Since the extension cord will be carrying low DC voltage, can I run it parallel to (or even touching) the shielded instrument cable that connects my floorboard to my amp, safely ignoring the usual signal interference concerns that come with running a full-on 120V power cord too close to an instrument cable?
