I currently am using the unbalanced mini with my AV15 off the 500 watt BASH plate amp. My plan was to get an additional 18" driver, and power each sub with one channel off the EP2500. I purchased the balanced mini and all the connectors/adapters needed for it.

But now my plans have changed and I'm looking to do a UXL. Question is--now that I'll be using both channels bridged for the UXL, can I safely drive both the pro amp and the consumer amp with the balanced? Will the extra voltage of the balance mini overdrive the plate amp?

The plate amp is unbalanced in, no? If so the output of the MD is the same as for the unbalanced as you are using only one polarity of the balanced output. 0.9V shouldn't overdrive the BASH.

Thanks for the info. My understanding is that the balanced has higher voltage so that it can drive pro amps to full power as opposed to the unbalanced. Pretty sure there was lots of discussion about this in the main minidsp thread. Wrong?

The reason the balanced has more output is there are two polarities (some people call them phases) so twice the level. You are only using one to drive an unbalanced input of the BASH so you are getting 0.9V at 0dBFS.
