Hello all,
I had the Sanders Sound System 10c years ago with the Innersound ESL amp and was impressed with both the amp and speakers...reluctantly sold the two....
Anyway, just playing around with a Kaya Crossover / Bass Amp - used to drive his 10" transmission line woofer (steep crossover at 450hz) while the provided High Pass XLR outs going to another amp to drive the ESL panels. The Crossover / Bass Amp has separate Mid, Bass, and overall Level controls - set the overall Level, then the Mid and then Bass to your liking to match the ESL panels, and the overall Level controls the level on bass amp and the XLR outs for ESL panel. Also of note the Bass amp section is exactly like the standard Full range ESL amp, but with the added bass only crossover and high pass out for ESL, all done by the Daughter board.
After researching this post where someone had same Crossover / amp that had a bad crossover Daughter board, he converted the amp to run full range by just jumpering directly from the XLR jacks to the amp board.

I could just wire the output XLR to the amp board, but I will try to see if I can jumper the socket to bypass the Crossover Daughterboard first.
Anyone done this yet?
Also still cannot determine what the EXP button does!!
EDIT - Roger just replied - the EXP button does nothing...just an extra button that may have had plans someday...
