I read this on a forum-

First post-
"Hi guys, so I bought an Emotiva XPR-5 and it has the option for 120v or 230v. My question is this, would the amp perform noticeably better if I ran a 230v outlet? "

After someone else replied that it wouldn't, he posted:

"I'm an electrician and my panel is directly below the wall that would receive said outlet so that's not an issue. I'm trying to balance the pro's and con's."

"I'm also thinking about buying a surge arrester but I don't see many 230V options"

"I would use a single throw 2 pole breaker with a 20A outlet."

and "The outlet that is there right now is running on a 20A single pole breaker"


My guess is, he's young and hasn't seen much audio equipment or hasn't paid attention to what ANYTHING uses for line voltage.

If he can't operate that beast, then by all means he can give it to me. :-)

Why does it even have that selector on the back? Typically you'll see that so that the device can be used world wide and such. But on Emotiva's website, it says that they can not ship it outside of the USA. [Link: emotiva.com]

That is because someone else has the global sales rights.

Got me- maybe they're working on CE rating. Or, maybe they want to start a trend- operate on 230VAC so they can charge more.

Kinda like the old "car audio" days...."The lower the impedance, the more bass I get".. lol

He's solid American and a product of our educational system. That big number (230) is there for a reason, right? Twice as big must be better, right? -- Why else would they have that big number?

- R - I - G - H - T -

(sigh)

But also perhaps because a product with that selector cannot get a UL rating in the US.

That's fair warning to the folks on that forum.


That's because of the country you live in, dummy.


I found "throw" puzzling here. Some research and incredibly fast and helpful answers from two people in customer service at The Pacer Group informs me that with circuit breakers, "throw" is not used as it's used with a relay or switch.

It has to do with how many sticks come out of the breaker. A single throw breaker has one lever for turning it on and off. A double throw breaker has two levers. That is, it's two single throw breakers, each on a different phase, tied together so that when one is tripped electrically, the other is tripped mechanically so that neither leg is left live.


Jeez, I hope it's that.



Where was this?

Or rating car power amps in 'Sony Watts', 'JBF' or 'WLS', right?

Audioholics. I'll assume he has already been beaten to death about his terminology, by now.

I'm just annoyed by electricians, at the moment. I hung a TV last Monday and the guy drilled one hole in the brick fireplace surround for the BX and another for my cables- he did great on my side and then blew out a big chunk of a brick on the other when the drill came out. That wouldn't be so bad, but he threw it away when he cleaned up and I wanted to put it back in, so the molding wouldn't need to be so large. Than, while I was working in the basement, he decided to put the electrical box one brick too high, so it's visible from the kitchen. On top of it, every time he came in from his van, I smelled alcohol- I don't think it was Purell, either.

Your use of "so" implies that there was some purpose or reasoning involved. I'm sure he didn't give it a first thought, let alone a second thought. He probably conceived of that step as putting the box "up there somewhere."


My dad had a clarinet player in the late twenties who had to take breaks often and usually came back smelling of peanuts... or something. My dad implied it was wine. What a scourge alcoholism is!

I actually told him to place it in the 4th course from the top and he went with the 3rd. He seemed to be able to count, too.

What's the problem? As long as it meets code ... .

Years ago we were running a lot of CAT speakers with ADA amps set at 230volts.. It's what both companies recommended.
