Currently have a 5 channel Gen2 and a 3 channel Gen1. I plan to sell the G1 and get a 6 channel to go with the 5chan. I have very efficient speakers up front and plan to use the 6 channel to power my surrounds and ATMOS overheads. Now to the question. ON the product page i can go with 6 mono modules or 3 stereo modules the later being much less expensive. I am finding the power ratings confusing between the 2 amps but it seems the mono modules will put out a ton more power which i dont feel is required for the surrounds. Basically looking for confirmation on my deduction skills here .Gen 3 really added a lot of options and i am really good at talking myself up.

Richard Can't opine on atmos, however, surrounds really don't need a lot of power in my set-up. Don't break the bank for the side dish. |

Mains and center need the power the rest can be 3dB less power wise.  |

I hear ya,but for whatever reason i always want more POWA . LOL I finally got a handle on the layout of the webpage and specs for the stereo vs mono modules. The mono modules seem to have a better quality amp on board and use class H to get that power. I really hate buyers remorse. thanks for chiming in fellas

The higher voltage rail is not there to get more power, that voltage level is required to get the power rating being sold. It is the lower voltage rail that is used for those times when the power demand is much lower (most of the time) and therefore less power is wasted. In other words it is a power efficiency driven feature that does not necessarily buy you performance. |

Or save even more money and get slightly more power (than the stereo modules) by getting a BasX A-700, but it seems you really want the mono blade setup.

Ok thanks did not know that about class H. they put it in there like it somehow makes one module better than the other, marketing strategy i suppose. Honestly i dont even play my movies that loud, not even close to reference. |

Just go for 6 of the DR-1's...overkill can be fun.

I've been looking at the A-700, an XPA with stereo modules, or possibly re-purposing a Dayton 12 channel amp I have (That can be bridged down to six channels).

I am going to add a question here. I have an option of adding another XPA 3 to get me to 11 channels which would be a bit bulky but doable or i can sell my XPA 5 and get an 8 channel Gen3. Now my question, will the SMPS power supply be a downgrage which i feel it is or will i honestly see /hear no difference.

As noted above - why not get something like the Emotiva UPA-700? I have a very similar amp - the Outlaw 7075. Its pretty stout - it comes in at 41 pounds. Actually I wouldn't buy an amp by weight - I know better since I've had a few class d amps. Crown and Rotel. I had a 5 channel Rotel class d for a time - the 1066. Nice sounding amp - it uses the Bang & Olufsen 100wpc modules. 180wpc into 4 ohms IIRC.

hello emo community
how many ampere minimum power do you need 2 XPA-1 Gen2 monos?
I go in front of the fuse box over AHP sound module III G fuse 16 / 20amp
Is 1 direct line enough + 1 fuse? or do i need 2 lines + 2 fuses?
best regards peter thailand

The SMPS absolutely will NOT be a downgrade. HOWEVER, note that the XPA Gen3 chassis has SEVEN module slots. That means that you can get an XPA Gen3 amp with up to seven of the 300 watt modules; but you CANNOT get an XPA Gen3 with eight of the 300 watt modules. In order to get an XPA Gen3 amp with eight channels, at least two of those channels would have to be on one of the lower-powered stereo modules (65 watts x 2). I am going to add a question here. I have an option of adding another XPA 3 to get me to 11 channels which would be a bit bulky but doable or i can sell my XPA 5 and get an 8 channel Gen3.

Correct..... The more powerful modules would deliver the same power if we were to eliminate the lower rail..... but with lower efficiency. The lower rail "buys" us better efficiency at low-to-middle power levels. (The lower power stereo modules actually run on the lower voltage rail - because they simply don't need the higher voltage provided by the higher rail.) I hear ya,but for whatever reason i always want more POWA . LOL I finally got a handle on the layout of the webpage and specs for the stereo vs mono modules. The mono modules seem to have a better quality amp on board and use class H to get that power. I really hate buyers remorse. thanks for chiming in fellas You may be looking at Class H wrong.

We do consider more efficiency / less heat to be "better". (You could look at it the other way; for the same amount of power dissipation, and the same power going in, more efficiency means you get more power out.) The output stage is really just Class A/B either way - which sounds great. A Class H power topology is not going to make some sort of mystical improvement in sound quality. What it does is to maintain the SAME great sound quality - while improving the efficiency You may be looking at Class H wrong. The higher voltage rail is not there to get more power, that voltage level is required to get the power rating being sold. It is the lower voltage rail that is used for those times when the power demand is much lower (most of the time) and therefore less power is wasted.

Then again if you live above 40 degree longitude, and you need whole house heating almost year around, then you may consider class H an unnecessary expense!

If i do well on it then i can get what i want rather than what i need In all seriousness...the web page is pretty confusing about how much power the various options have. Seems like it's ripe for a table, but it does look pretty clear that the stereo modules are a lot lower power than the single channel blades. Seems to me that the answer depends on how efficient your surrounds are. If they are really efficient, odds are the 2 stereo blades will be fine. If not, the mono's give you a nice buffer of plenty of power. Mark |

If you're intent is to use the extra amp channels with ceiling speakers, and your ceiling speakers are in the neighborhood of 89db/1watt/1meter then you more than likely don't need more than about 35-40 watts RMS of power per speaker to reach Dolby spec (85db average with 105db peaks). Even adding an additional +3db of headroom at 80watts, when you consider all the other speakers that will be playing at the same time, you're crazy dangerous loud, and I'd be wearing ear plugs at that point! |
