I am in the process of building a dual purpose Home Theater/2 channel system for my livingroom. I have Salk Songtower speakers and am looking for suggestions on quality multi channel musical amps up to $2500.00 that will turn on and off by a remote or audio signal recognition.

I am wanting a system where I dont have to go to the av cabinet to turn on the amps, pre amp etc just to watch tv.


Your thoughts are greatly appreciated.

your preamp will have to be powered on as well, no? many amps have 12v trigger inputs, so they will power on/off with a 'master' device (typically the preamp)...but that master device must also have a 12v trigger out.


alternatively, there are power strips that have current sensing outlets...ie: one device comes on (drawing current from the trigger outlet), and the rest of the strip is switched on.

Are you using "amp" as a shortcut for "receiver"? Or you actually mean "amplifier" -- which is separate from a receiver or pre/pro?


Most amps have a wired12v control input. Most higher-end AVRs and pre/pros have a 12v control output.


FWIW, I use a Marantz MM9000 5-channel amplifier which has a wired control input. Its replacement, the 8 channel MM8003, also has muting for individual channels, but (as best I can tell) needs to be connected to a Marantz AVR or pre/pro in order to get the appropriate commands over the control cable.

I am meaning an amplifier. I am looking for an 5-7 amplifier in a single box that is able to be turned on at the couch. My enclosed av cabinet allows for the amplifier to be no larger than 17" deep.


Hoping to find something that mates well with a parasound 2100 pre amp and a Music Hall 25.2 Dac or AVA Vision Dac. The prior items will be combined with salk songtowers speakers and a Squeezebox duet.


Looking for a nice sounding system that can be operated easily by others in the family.

Isn't the 2100 a stereo pre-amp? What pre-amp are you going to use for your new 5-7 channel amp? The pre-amp should have a 12V trigger to turn on the amp. If not, there are some work-arounds for it's absence.

Sorry!


I have a onkyo 807 receiver, Oppo BD 83 Blue Ray Player and need to choose a multi channel amplifier to take care of the Home Theater side.


The 2 channel side will have the Squeeze Box Duet,Parasound 2100 pre amp and Music Hall 25.2 or ava vision Dac using the same multichannel amplifer as the home theater side.

Oh, ok. Got it!

The 807 has 12V trigger jacks on the back. So long as you choose a power amp that has a 12V trigger input (most consumer amps do), it will power on automatically whenever you turn on the 807.


Since you're using a receiver for the pre-pro, consider just a 3-channel separate amp for the front speakers. The receiver's internal amps should do a fine job of driving your surround speakers (which don't usually require as much power, anyway), especially if the receiver doesn't have to devote any power to the front channels. Even a solid 2-channel amp for your music listening and letting the receiver drive the center and surrounds for HT might work.


You may want to check out the Emotiva XPA line. They're pretty well regarded around here and won't bust your budget.

He might want to doublecheck his documentation. Onkyo may have changed it with the 807, but the 805's 12v trigger only works for Zone2 output when one wants to use the onboard amps for a full 7.1 along with 2.0 in Zone2 instead of reassigning the surrback amps to Zone2.

Hmm, you appear to be correct. I just took a look at a photo of the back panel on the 807 and the 12V trigger outputs are labeled "Zone 2" and "Zone 3." There's no switched AC outlet on the back either, so you can't create a pseudo Zone 1 trigger by plugging in an AC-DC converter.


Depending on exactly how the 807 operates (I've never used one), and if the OP doesn't need the Zone 3 capability, he may be able to set up a remote-control macro that activates the Zone 3 trigger whenever he turns on the receiver, and use that to switch the amp on and off.


If this isn't feasible, a "smart" power strip like is the simplest option: http://www.smarthomeusa.com/ShopByMa...td./Item/SCG3/

I use one of them myself, as my pro-amps don't have 12V trigger inputs.


There are a few other solutions out there for boxes that can accept a remote-control command to activate triggers, but I haven't used any of them.

Parasound amps can turn on with either signal sensing or 12v trigger
