The rack for a permanent install will have a DBX Zone-pro, several music sources, and a wireless mic. All on a rackmount power strip on a dedicated 20A circuit.
Also in the rack will 4) RMX2450 amps. Each on it's own 20A circuit.
Should all chassis be grounded together though the rail? If so, do I need to grind paint at strategic locations, run a tap through tapped holes to remove paint, etc? Is there a better / alternate way? Is it even needed?
I will be using the barrier strips for signal input. Is the ground of each input attached to the chassis? Can I / should I use that as the ground points by jumping from one unit to the other? Can I assume that the wire could just be signal size (20-24 awg)?
At this point, earth ground is made though all units power cords, correct?
Thanks,
David
