[QUOTE="Thomas Dameron, post: 58487, member: 1098"] Re: amp reconfirgure mode - what to do... One of the companies I freelance for has a pair of racks with 3x FP10k. They mainly use them as 6x mix bi-amp monitor racks or 1 rack/side driving a Martin W8LM (2x 8") arrays. The FOH config closely resembles what you're doing. They do the top two amps in the rack doing 4 bi-amped circuits down to 4 ohms, the bottom amp drives subs. It usually gets 1x 4ohm sub per amp channel for the amp doing subs, but other times some channels get two cabinets. They've got enough sub specific racks that we've never bothered trying all four sub channels down to 2ohms. The performance has been great for the ~2 years they've had these racks. They usually carry one multipurpose rack that could replace any one FP10k if it were to fail. I appreciate your concern with the liability of an amp failure causing a show stopping or at least pausing event, but unfortunately I think that's the reality of using a 4ch amp on a medium/small rig. I think it would be a no brainer to keep at least one of your Plx3402's in a small rack as a spare to at least restore partial functionality. I've never had any issues with these amps, but in our line of work it's a matter of when and not if you have a failure at some point. LG's support is supposed to be some of the best, but that won't help you the night of when the smoke gets out. thomas d. [/QUOTE]
