2 Channel amp question (1 Viewer)

[Chris M34]

Why does the 2 channel amp have 4 sets of speaker wire outputs? What benefit do you get from running Speaker channel A to the top posts of your speakers and speaker channel B to the bottom posts? I hope I am writing this correctly?

The Speaker A and Speaker B terminals are generally used to switch between pairs of speakers that may be in different rooms.

If your speakers have two pairs of binding posts, they are "bi-ampable" - with one pair of posts feeding the highs and mids, and the other pair feeding the woofers. If you are going to bi-amp your speakers, you must remove the metal plates that connect the two black posts and the two red posts.

That being said, bi-amping your speakers using a single receiver or amplifier is a waste of time (not to mention speaker wire). You aren't gaining anything at all - since the receiver is still pulling the same amount of power from the wall.

Speaker A/B selection is NOT intended to be used for bi-amping a single pair of speakers (by keeping the selector at A+B). There is absolutely no reason for doing this as there is no benefit to be gained.

Makes total sense now. Does it matter which posts you wire to once the jumpers are attached?

Nope - the jumper plates electrically link the binding posts. You can wire the upper black and the lower red and it wouldn't make a difference.
