Bought a XPA-5 connect to my yamaha AVR, I hook up the AVR pre-out to FR FL C SBR and SBL , so the Yamaha AVR will only handle the SL and SR, when I use a SPL to balance all the output, which is :
FR - 0
FL - 0
Center - -1
SL - 8.5
SR - 6.5
SBL - 0
SBR - 0
So my AVR have to add 8.5 and 6.5 (gain)to balance the sound of the XPA-5, will it putting too much pressure on my AVR, or should I lower the (gain)output on the other channel to the XPA-5 to less the pressure on the AVR. Or lower the gain of the SL and SR to 0 and make all the pre-out to XPA-5 to all negative number.

I think you will be ok at what they are set now to, the XPA-5 can output up too 300 watts into 4 ohms pre channel.Maybe one of the Ole Timers will come in on your Thread and help out more than I can.It has a really nice power supply so I don't think any harm will come too your XPA-5 its a Beast of a amp.For a 5 channel amp to have the output that the XPA-5 has and the price of it makes it a no brainer.You are in for a Lot of fun with that amp my XPA-5 stays on all the time and it will be a year old this May 5.Rock on Bro and may the power of the watts be with you.

i'm curious, why didn't you use the XPA-5 for the FL, FR, C, SL & SR and let the receiver do the SBL & SBR? i'm just figuring the most sound is going to come from the main 5 and the least from the SB2.
i'm also sure any way is fine, just curious. i have a 7 channel setup to and use the XPA-5 for the channel config i mentioned and a UPA-2 for the SB2 channels.
also, what speakers do you have and what are there db ratings?

Because I have some problem in the center channel when there is a sudden vocal volume change-- usually a male voice yelling. Sounds like clipping or distortion.
Thats why I think the gain from my AVR to the XPA-5 is too high.

My center speaker is the Paradigm cc690, without connect to the XPA-5, no problem before. |

My center speaker is the Paradigm cc690, without connect to the XPA-5, no problem before. so your saying that the problem started after you connected it to the XPA-5? your giving really short answers; you need to give a bit more detail in your responses for us to really help you out. are you saying that when you had the paradigm center connected to the avr directly it played fine and that your sound issues with it didn't happen until you connected it to the XPA-5 amp? please be specific in what happened and when. trust me, folks are going to ask you the same things to try to give you the best answer. you have got a very nice center channel there. it's a big boy too like my Axiom VP-180v3. both of them will perform much, much better with more power available from an ext amp! |

another thing is, if you want to see if it's the amp try moving the speaker wire to the center and it's interconnect from the avr to a different channel on the amp. if the problem follows the speaker it's the speaker. if the problem shows up on the channel that you have swapped with, it's the amp.
again, make sure all your connections are tight; this includes your pre-out interconnects!

i'm curious, why didn't you use the XPA-5 for the FL, FR, C, SL & SR and let the receiver do the SBL & SBR? i'm just figuring the most sound is going to come from the main 5 and the least from the SB2. I agree, I would connect the XPA-5 to the main 5 channels (L,R,C,SL & SR) and the AVR to the SBL and SBR. The SBR and SBL typically carry a lesser load, so would better suite the AVR's lesser power output. As for the centre problem, I'd also suggest checking the connections very carefully, connections are always my first port of call. If you find nothing there then I'd try swapping channels on the XPA-5. That should find or eliminate an amplifier channel problem. Cheers Gary |

Or lower the gain of the SL and SR to 0 and make all the pre-out to XPA-5 to all negative number. I think it's fine the way it is. But I would run the SL and SR to the XPA-5 since there is far more material in 5.1 vs 7.1. |
