Hello forum and thanks for having me.I currently run an Integra DTR 50.3(2 ch mode only)..Pre outs to a 6 way splitter box into 3 amps.2 Crown XLi 1500 and a QSC GX5.Speakers are 3 pair of 4 ohm Cerwin Vega's.The AT-15's,D9 and VE15's. Sounds absolutely great.Plenty of headroom etc..Now I'd love to get rid of the 3 amps and go with 1 Emotiva XPA 6.My only concern is will the Emo give me 6X 490W?The website only gives 2 channels driven.Thanks for any help.

It's there: 225w per channel, all channels driven. I did not see a spec for all channels driven, 4 Ohms. Edit from website: 225 watts/channel RMS into 8 Ohms; all channels driven |

Good question though and welcome to the madness! |

That's why I'm wondering what all 6 driven at 4 ohm are. Few manufacturers would give a 4 ohm ACD spec (I don’t remember seeing any multichannel amps rated that way, but maybe some do). It would be very difficult for the amp and difficult to reproduce, you could ask but I’d be surprised if they’ve done that test, do you know others who have? |

I'm going to echo what several folks have already said... which is that we don't usually measure that or specify it. (The reason is simply that it isn't at all a realistic measure of how the amplifier will perform in actual use.) Music is dynamic... This means that, if you were to turn an amplifier up to the point where it clips on peaks, using actual music, its average power output would be about 1/10 to 1/20 of the peak value. And, in addition to that, with real music, you will virtually never see even peaks demanding full power on more than one or two channels at once. So, in terms of "dynamics", or "dynamic output", any two channels of the amp will deliver the same power as the "two channels driven" rating, from ANY two or three channels, short term. And, yes, if you were to measure the power output "continuous - all channels driven", it would be somewhat lower. But, since that is totally unrealistic in terms of real world use, we don't bother to measure or publish that value.

Thank you very much for the response.I am fine with it not being a full 490.I would say around 300-325 would my target. I don't go full out too often.Maybe a couple times a week for an hour or so. I guess I'm looking for a "Yes it would work fine without melting down." 😂 It's mostly for home movies, X-BoxOne type duty 24/7. |

Right.. That's why I'm wondering what all 6 driven at 4 ohm are. Few manufacturers would give a 4 ohm ACD spec (I don’t remember seeing any multichannel amps rated that way, but maybe some do). It would be very difficult for the amp and difficult to reproduce, you could ask but I’d be surprised if they’ve done that test, do you know others who have? This is what the Monolith 7 says: Model 14566 Inputs 7x unbalanced RCA, 7x balanced XLR Number of Channels 7 EIA 1kHz Output Power at 8 Ohms* 250 watts EIA 1kHz Output Power at 4 Ohms* 375 watts FTC Full Bandwidth Output Power at 8 Ohms** 200 watts FTC Full Bandwidth Output Power at 4 Ohms** 300 watts |

It would be very difficult for the amp and difficult to reproduce, you could ask but I’d be surprised if they’ve done that test, do you know others who have? The rest: All power ratings are measured with all channels driven. * EIA 1kHz Power refers to maximum average power in watts at 1kHz with 0.005% THD and noise. ** FTC Full Bandwidth Power refers to maximum average power in watts from 20Hz to 20kHz with 0.03% THD and noise. |

That's pretty good and seems reasonable (as in, not much current left in the wall), I'd think the Emo would be similar. |

I guess we'll find out when I buy one.Need to save a little first.This economy is tough right now. |

IMO? You are worried about the wrong thing. Power? sure. but what is the sensitivity of the speakers being run? And how LOUD do you like it? Cerwin Vega is typically more sensitive than average. If you use more than 5 watts per speaker, that's a LOT......I see claims for 100db + which I suspect is a little optimistic.....I wouldn't be surprised if they really measured 96db.....which is STILL a very sensitive speaker..... And besides? Those crown amps? Huge claim but what are they REALLY capable of? The QSC amps you mention? No such thing as Class 'H' output. They are referring to a power supply topology.....Used, incidently by some EMO amps with the big switchers.... And the mention of Class 'B' output is to be avoided. That's where A/B comes in which is audibly better in most cases.... The 6x500 (roughly) you require is 3kw. double what your 15 amp service will provide.......You DO have a couple dedicated lines for only amplifiers, right? Just my opinion, but Better watts are.........Better........ |

Now I remember why I left forums alone.Cut back on the caffeine.🤦♂️🤦♂️ I asked a couple questions.Got what I was looking for and you come in like King Kong acting a fool.Have a nice day.Smfh |

That has always been a good go-to reply.
Don't like the answer? go after the poster....
Have fun with your system as you explore more options......
You're not stupid, so stuff should eventually start to click......
Cheers.....
