I was curious what can the two speaker outputs be used for on the UPA-1’s? It’s a mono block so why would it have that many speaker positive/negative connections?
I’m guessing you can’t remove the bridge from your speakers and use a four conductor speaker cable on each end of the wire to connect them, correct, like a bi-amping setup wire? Meaning there would be four speaker connections at the UPA-1 side of the speaker cable and four at the speaker with the speaker bridge removed.
What’s it’s real purpose?

Is there supposed to be a bridge on the back of the UPA-1?

No, if your speakers have 2 sets of binding posts you could remove the bridge connecting the binding posts on the speakers and use two pairs of speaker cables to each speaker, I owned the UPA-1 and one set from the UPA-1 was just fine.

So you have all four speaker outs on the back of the UPA-1 connected (+ - + -) going out to the back of your speakers with the bridge removed on your speakers, you then connected four speaker connections (+ - + -) on the back of your speakers?

Just use one set out to the speakers and one set in. It's that simple. I have owned 4 UPA-1 and have always used them in the aforementioned manner.

Just remember to remove the bridge.

So when I connected this speaker cable and I did remove the bridge. goo.gl/images/WJXwNHIt sounded like crap. There was almost no low frequencies and sounded like it was in a church. |

Can you tell me what’s the point of those four binding posts instead of two on a mono block?
What real purpose does it do? I don’t know or think I can hear a difference either way but why would emotiva put them there?

I don’t know or think I can hear a difference either way but why would emotiva put them there? To me there is no point for them at all. If you open the amp which I do not recommend you do by the way, you can definitely scratch your heard thinking about why are they there. |

The double speaker posts are there for the people in the world that find 'buy'-wiring makes a "night and day" difference - or is that "lifting of the veil"? Ditto for the speaker manufacturers who dispense dual sets of posts. I'm sure the speaker cable makers heartily recommend buy-wiring, as do the termination makers.

Also four binding posts means you get more thickness of wires. IF you care about that sort of thing. So two 12 guages of cable to your speaker.

Bumping this old post to ask:
Can I power two 4ohm speakers (magnepan 10.1) with this mono amp? It has two speaker outputs.
It will be used for a two speaker center channel.

Bumping this old post to ask: Can I power two 4ohm speakers (magnepan 10.1) with this mono amp? It has two speaker outputs. It will be used for a two speaker center channel. You could use a used XPA-2 gen 2. Split the mono signal in to two, one per channel using an RCA splitter. Attach each split side to their own left or right channel on the XPA-2 Then attach a speaker to the left and right channel each. As long as you don't bridge the XPA-2 gen 2, this would be an excellent use for this. |

If possible, I want to avoid splitters. I'll probably end up using a separate preamp / EQ just for the center.
