I have three of the Active crossovers, here is a pic of one of mine, all three are much different from each others
Thank you Ken - I appreciate it. It seems that the seller took the "transformer" out and replaced it with the external power supply box.
Tomorrow, I will try to use this crossover with my kappa 6.1 - if this is a bad idea, then please let me know - otherwise, I will report either success or I have a blown Kappa and/or Carver. The Carver is non-inverting, so at least I have done some homework. I really have some reservation to plug that power supply box into the outlet. Those capacitors are bigger and more numerous than what I have seen inside my carvers.
Yikes, I would be nervous about running a different brand of bass drivers than the one designed for the active crossover. For one thing those active crossovers are full of OP amps, that are pretty easy to fry, I had a pretty long talk with Bill Miller about them. He doesn't even like to fool with them any more because all it take is customer to hook it up wrong and you blow the op amps. If I recall there are at maybe 8 or more op amps in that crossover. I think the crossover uses some method of measuring resistance to the bass drivers to increase the amps current to correct the bass drivers. Unlike the Beta's which have a bass driver which measures the movement by a special accelerator thing. So if you hook up the unit to a driver set up that has some different resistance it might cause some real problems. I don't know this to be the case, but I personally would just hook it up to the speakers it was designed for, and when powering up keep the volume at zero, and then slowly bring it up. If you amp for the bass drivers have gain controls, I would also put them at minimum and then very slowly advance them up. The first pair of my RS-1b's I purchased the OEM crossover had a problem, the customer who sold them to me that something didn't sound right with the speakers but he never could figure out what it was. When I purchased them and hooked them up I knew instantly the problem was the bass was hardly there. I used a Rane active crossover and it was like night and day. I tore it apart and talked to a few people including Bill Miller who is suppose to have a pretty good rep on these speakers, he told me, replace all the op amps. That is what I did. Most are easy to get to, but their are a few on the back board which requires having to remove all the rear terminals to get to the board. When replacing the OP amps, they have to be placed in a certain direction, their is a small inditation on the top of the chips, make sure you place all of them if you ever have to, with the small dent in the right direction. I found plenty of sources for the right op amp on line, I purchased like 20 of them for pretty cheap money. Mr Miller told me that the op amps were the problem 9 times out of 10, so if yours has a problem thats where I would start.
As for your outboard power supply who ever modified it, sure beleived in a lot of extra capacitance, I would have never thougth that the crossover would need that much capacitance, but then what do I know.
