derrickdj1 Posted September 24, 2013 Share Posted September 24, 2013 Darn Scrappy, plug the amp up. You don't have to stress it[]. That should be one beast of an amp[H][Y]. Quote Link to comment Share on other sites More sharing options...
Scrappydue Posted September 24, 2013 Author Share Posted September 24, 2013 Can't bro, it literally has a 20amp plug that I have to buy a 20$ adapter for. So might as well spend a little extra and give it it's own line. Especially since cecca pointed out warranty issues incase I'm not running in it on recommended output.

Islander Posted September 24, 2013 Share Posted September 24, 2013 That looks like one heavy-duty unit. I just looked at a review on it that even suggests running it on 220V for best effect. That seems a bit extreme. I've got a pair of 500Wpc amps plus a 500 watt sub running on the same circuit with no issues. When driving Klipsch speakers, it's not likely you'll ever use much of the amp's power, except during transient peaks. It is great to have all that headroom for those parts of the music, though.

Scrappydue Posted September 24, 2013 Author Share Posted September 24, 2013 I run everything you see in my profile in the theater room off of a single line. And never demo'ed loud enough to pop a breaker. Now I have been to two different demos in which both guys blew breakers but one was 8db above reference and another was 16 db over reference. And both those demos were with 4 ohms speakers. Quote Link to comment Share on other sites More sharing options...
jason str Posted September 24, 2013 Share Posted September 24, 2013 If you were going to run a separate circuit may as well run a 220 line while you're at it, not really that much more expense if your main panel has the room for the extra breaker. By the way nice looking unit.[Y] Quote Link to comment Share on other sites More sharing options...
jason str Posted September 24, 2013 Share Posted September 24, 2013 I wanted to add running off a 15 amp circuit is not going to harm anything. What it will do is not put out full power when you really need it at higher volume and sacrifice your extra headroom. Your existing 15 amp circuit should be 14 guage wire. 20 amp should run a 12 guage wire & 20 amp breaker. 220 volt 30 amp circuit should use 10 guage wire. If you feel you can do it yourself and need help feel free to contact me and i will guide you through. Quote Link to comment Share on other sites More sharing options...

That seems a bit extreme. 220V as in European power? That is not the same as our 240V. You should not attempt to connect this to a 240V outlet without substantially changing the electronics inside the amp unless the operating instructions tell you to do so. Euro 220V is single phase, and US 240V is two phase. I doubt the amp has a 4 prong outlet necessary for 240V. Quote Link to comment Share on other sites More sharing options...
Scrappydue Posted September 24, 2013 Author Share Posted September 24, 2013 I think he meant 220 as in like what a dryer would use. But it doesn't matter, I will never be pulling that much juice from this thing. A regular 20 amp line with a 20 amp plug will be plenty. And only doing it for warranty purposes. Like I said I run two amps on it already and NEVER run then even close to hard. Quote Link to comment Share on other sites More sharing options...

Scrappydue Posted September 24, 2013 Author Share Posted September 24, 2013 Thanks for the suggestions but I am not going to run a 220 line. You should know with your la scalas that Klipsch do not need that kind of power. My speakers are crossed over at 100 hz and I never go above reference. So there is just no need for it. This line is going to be temoporary as I am in a family rental. So it will get taken out once we move. Wanting to keep price down low as possible.

The Dude Posted September 24, 2013 Share Posted September 24, 2013 Looks huge, was the 20 amp do to the heavy current the transformer this thing has pulls. Thats heavy. Quote Link to comment Share on other sites More sharing options...

Heritage_Head Posted September 25, 2013 Share Posted September 25, 2013 I think all their amps come with a 20amp plug. my sherbourn 4z-75 power amp came with the same plug. It should have come with a normal plug too (mine did). You don't need it but if you want to by all means. Quote Link to comment Share on other sites More sharing options...

There should be a switch in back of the power supply to switch back and fourth from 110v to 220v. Yes, that is to switch from USA power (120/240-60Hz) to Euro power (220/50Hz). Not the same thing as a 240 volt clothes dryer outlet. In a 240 receptacle, two of the spades are 120V legs. In Euro power, one leg is 220V to ground. I'm pretty sure you can't simply twist two 120V hot wires together to make 240V and be in electrical code compliance. I am not a licensed electrician, but common sense tells me you don't want to. For that reason, you would need to do voltage conversion via transformer to step the 120V up to 220, which would be silly in this situation. In this situation, if you need a higher (20A) amp receptacle, run large enough wire and install a large enough breaker to install the higher amp receptacle.

mustang guy Posted September 25, 2013 Share Posted September 25, 2013 As the sherbourn 4z-75 power amp uses a 6.3A 250V slow blow fuse(1575 watts), 15amps should be adequate power at 120V (1800 watts). How big is the fuse in the PA7-350??? Quote Link to comment Share on other sites More sharing options...
mustang guy Posted September 25, 2013 Share Posted September 25, 2013 I looked at the back of the Sherbourn PA7-350 unit, and the power requirement is 4,000 watts. I'm not sure what to make of that. That is 33 amps! edit: This amp has a 3.3kVa transformer. That's a biggie! Quote Link to comment Share on other sites More sharing options...
