The selectors are simply switches, some with impedance protection, but none can add power to the situation. Using A+B puts the two sets in parallel on most receivers and yours might not be able to put sufficient power out into the now lower load impedance. What is the impedance of the two speakers and what is the rated output of the Marantz into the paralleled load?
speaker selector
I have a pair of tannoy mx2 speakers and a pair of Kef Cresta speakers and am starting to explore whether or not to purchase a speaker selector. Could anyone let me know how the speaker selectors operate, what brands to look at and whether or not these selectors will prevent the loss of power I seem to experience when I play both sets of speakers through my A and B channels. I have a Marantz sr-48 receiver.
Thanks
