Silver Member Username: Nickb4247Post Number: 118 Registered: Dec-06 | I am putting together a home theatre for a freind. We are doing a 5.1 system in the living room. But, he has 8 out door speakers he wants to power as well. I need a 8-12 channel power amp that will do the job. any where between 30-50 watts a channel should be plenty. It will be connected to the pre-amp low level outputs on the surround sound amp(havent decided on that yet either). Not trying to spend a ton of money on this amp. But, my specialty is car audio. I know what a reasonable price for a decent amp is in that field. I am clueless with this. Help. |

Nevertheless, here is exactly what you asked for, a 12 channel amp that delivers very clean power, but has an MSRP of $2800: http://nadelectronics.com/products/custom-installations/CI9120-Power-Amplifier Here is one that I found that is factory refurbished at a substantial discount: http://www.spearitsound.com/nad/CI9120.asp If you friend will suffice with 6 channels, I found the "little" (its all relative!) brother of the above amp here: http://www.audioadvisor.com/prodinfo.asp?number=NACI9060 and here: http://www.spearitsound.com/nad/nadspec.htm Also, here is a Marantz that is also a six channel distrubuted audio amp: http://www.accessories4less.com/cgi-bin/item/MARZS5300 Now, this may be more than you want to spend, but since you didn't give us a budget, I am shooting in the dark. Please understand that "distributed audio" is one of the latest "things" so it is hard to find and can be rather expensive. However, a less expensive way to go is with four seperate two channel amps such as these: http://www.partsexpress.com/pe/pshowdetl.cfm?&DID=7&Partnumber=302-601 I hope this helps. Good luck! |

Silver Member Username: JethroLansing, Mi Post Number: 148 Registered: Jan-06 | look at niles for 12 channel power amps if your on a budget and looking to power 12 speakers. Don't get it quite tho, your looking for a power amp to drive 8 outdoor speakers plus 5 indoor in the HT, for 13 speakers total. What are you trying to do here? If your not looking for advice on setup and don't have a price range/goal etc... I'd definitely go with the amp that hawk has suggested. |

Silver Member Username: Nickb4247Post Number: 127 Registered: Dec-06 | I'm sorry I was so vague. The HT will be powered by it own 5.1/7.1(havent decided yet) amplifier. The HT amp will be the "pre-amp" for the power amp. The power amp will run 5 existing outdoor speakers plus 2 that might be added at a later date plus it might also run an extra pair in an adjacent room to the "home theatre" room. Thats a total of atleast nine. Since most power amps seem to be 4 ohm stable, I was thinking of just getting a 8 channel and bridging a pair of the outdoors. OR possibly running the extra indoor set in the adjacent room off of the remote speaker outputs on the HT amp. I am really looking to only spend around 1000ish on the power amp. Nothing fancy. The speakers hooked up to it will be divided into 2 speaker "zones" each controled by in-wall volume controls. Hope that clarifies. |

Gold Member Username: NuckPost Number: 5657 Registered: Dec-04 | nick, most power amps are NOT 4 ohm stable. For low impedence stability, you need to see Nad, Rorel and above. Yamaha, yadda yada cannot do this. Seek high efficiency highimpedence speakers. Like Klipch. |

Silver Member Username: Nickb4247Post Number: 128 Registered: Dec-06 | I like that factory refurbished NAD 12 channel. eccelent price. That would give alot of expandability. I think the system will end up consisting of a denon/onkyo 7.1 reciever. Prob in the 600-800 dollar range. It will power a KEF 3005 surround system(1500$(5.1)) There will be a pair of small bookshelves in the adjacent room. 200$(nothin fancy). The existing outdoors are all Niles. The additional outdoors will most likely be Boston Acoustics. The only other thing the system will need is a multi-disc DVD player. possibly just a 5/6 disc, or maybe a 300 disc(up to the buyer). |

Silver Member Username: Nickb4247Post Number: 129 Registered: Dec-06 | Most of the high end power amp I have looked at (NAD, Niles, ect) have been 4 ohm stable. |
|
Silver Member Username: Nickb4247Post Number: 130 Registered: Dec-06 | But either way, i can work around it. |

Gold Member Username: NuckPost Number: 5660 Registered: Dec-04 | Well to work around it, you must use 16ohm speakers, unless you use high current amps. But you da man. |

Silver Member Username: ThecryptLawrence, Kansas Post Number: 134 Registered: Dec-06 | I might be a little late but I'm using an Anthem P2 in my bedroom system (I love it) and they claim it stable down to DC (probably more like 0.0(something), but I was thinking maybe you could bridge all of each channel. That'd be probably around .8 ohms (10 speakers) or 1.6 (5 a channel) and from what I can gather would probably supply a total of 1500w (150 to each of the 10 speakers) or a total of around 1000w (around 200 to each speaker) at full output. From what I've learned from BCAE that would I assume all volume controls are all the way up and if any were turned down then since it's a variable resistor the impedance increase would decrease the power to those speakers and supply a little more power to the other speakers making them louder. That's just another option, but it runs $2500 MSRP (for plenty of power). I know you asked for a 8-12 channel, but I'm not sure exactly if you plan to run these speakers with different sources at different times? What can you do? Man I realize how much I've learned, crazy. |
