Trying to use the Lexicom MX400 in dual Stereo mode, all the cords are connected and the led for A will light and two speakers play. The led will not light for B and the speakers do not play. The other led lights work when adjusting the knob for surround, stereo. Wondering if the lexicon has a problem or could it be from using unbalanced cords?
A call to lexicon helped, dual mode a and b have to be set to the same program and both led's do not light at the same time. The organ is now playing through 4 stereo channels and 4 more to configure into the motu 4k ultralite! A very small room and was nervous about ordering the 8 Behringer B1030A. With the sub and just 4 going the sound is pretty amazing.
