[QUOTE="Rick Stansby, post: 24583, member: 312"] Re: When L21-30 just isn't big enough Rob, that's what we figured. 17.3A per leg, 2 legs per amp, puts us at 52A on X and Y, with 34.5 on Z, plus we would put some edisons on Z. Basically we'd need 50A per leg. That is what got us thinking about the 63A Ceeform connectors. In reality, only the sub amp is going to draw near 17A per leg. All of this led us to the original idea of 2@L21-30 with one driving the first 3 amps and one driving the sub amp. Allowing us to run the sub amp at 208V, and split the load between 2 of the legs of the second L21-30. Apparently this design will be very pricey for Motion Labs to build. I'd love to go down to 3 amps per rack - to make power easier. Unfortunately that doesn't cover our amplifier needs, and we would need to figure out a way to stack amp racks in transport. We are configuring these for 4@ tri-amped zones with 4 channels of Sub. Our old racks have 3 triamped zones, passive fills and 4 amp channels for subs (14 amp channels total). So we only have 2 extra amp channels in these racks, however we will be running a larger rig off one of these racks than we can run off the old racks. [/QUOTE]
