One 7B ST has a single set of speaker connects, the other has two sets with what appear to be instructions about how to connect 3-8 ohm loads, vs a low (down to 1 ohm) load. Both amps have a switch allowing for a Series or Parallel option, with Series driving a higher impedance load, and parallel driving the low impedance load. The problem is that on the amp with two sets of speakers connects, there appears to be instructions directing me to connect the speakers to different posts, depending upon the speaker load, and the series diagram looks as if it's directing me to connect the speaker leads to the two "red" posts.
I'm confused. Can someone help. My speakers are FB1's
