The knobs turn really good! See, the deal is, I'm slowly piecing (sp?) together my rig, and by the time it's done, I should have : -Sansamp RBI -QSC RMX1450 or Peavey PV1500 or 900 -Eden D-215XLT Anyways, I have a couple questions, and will be asking more questions as they come up in this thread. Since the Peavey's weight has just been reduced, and they cost the same (or less) as the RMX1450, and come with rear rack ears, I was thinking of getting one of those. Questiones: 1. Are the Peavey's good for bass? Are they better for PA, and not recommended for bass? 2. Does anyone use on of the Peavey's for bass? 3. If I get the Peavey, where does my preamp plug in? On the input section, it has LOW/THRU outputs. Would I put it there? Here's the only thing I could find about inputs in the manual: "When the crossover function is not activated, this (LOW?THRU) jack converts to a THRU fuction, where the out put of the electronically balance input circuitry is supplied to this jack. The THRU function provides the means to patch a full range input signal to the other input of this amplifier (parallel), or to other amp inputs in the same rack." Here's the link to the manual, to help me with the where to put the preamp question: http://www.peavey.com/media/pdf/manuals/pvamps_2004_manuals.pdf If I got the PV900, I would be runnin it bridged into 8 ohms until I got another cab, where I would be runnin at 4 ohms bridged, but if I got the PV1500 I would be runnin into 4 ohms on one side, until I got another 4 ohmer and would run it at 4 ohms a side. I'm thinkin I should have a rockin set-up! I absolutely love the D-215XLT, it is beautiful. How do you all think this setup will sound? Thanks for any help.
