How can I connect my loudspeakers to an amplifier and a/v receiver at the same time (speakers has only 1input)

I'm considering to buy Definitive Technology BP7004 front speakers which has only single input cable connections.
However I'd like to to use them with both my stereo amlifier and a/v receiver at the same time without the hassle of switching cables.
The option of connecting the stereo amplifier to the a/v receiver also doesn't make sense to me, since my stereo amplifier (DENON PMA-2000AE) is much more powerful compared to my a/v receiver should handle(also a DENON, AVR-3300) .

Any suggestions to my problem?

I'm not sure why do you not connect the front outs from the 3300 to the power amp inputs on the 2000E. I have the 3300 and use separate amps for all the channels. There are little loops that connect the preamp side to the power amp side on the 3300. Take the loops off and connect the front pre-out to your 2000e. I use Carver amps all around and the front stereo amps are 500 watts each channel ( I use 2 of them since my speaker (Polk SDA 1) is a bi-amp speaker. I use Carver 300 watt per channel amps on the surround channels. I simply adjust the preset channel levels for the watching TV/Movies and listening to music. For TV/movies I turn down the front speakers levels from what is used for Music/stereo.

  1. You would have to purchase speaker switcher. It would allow two sets of wire to connect to it, and one set out to the speakers. I beleive Niles sells a switcher that may work for you. http://www.nilesaudio.com

  2. I can only recommend that you use the front R & L preamp outputs of your AVR-3300 to connect to the R & L inputs of your PMA-2000AE.

    This way you are effectively using your receiver as a preamp to control your amp as an external amp for your mains instead of using your receiver's front channel amplifier. This could even free up some power for your receiver's other channels if the receiver is sharing amplification between the channels. On the other hand, if each of the channels have their own discreet amplifier per channel, it won't help that cause. If you plugged both speaker wires into your Def Techs, the output would be greatly reduced due to the halving of the impedance by running both amps at the same time into one speaker.

    Hmmm… Too bad your speakers are not bi-wireable/bi-ampable (with two sets of speaker terminals), because then you could run the receiver to your highs and the amplifier to your lows.

  3. You cannot connect amplifier outputs in parallel. Either get a speaker switch, or decide which amplifier to use.

  4. Try a set of RCA jacks hooked up to tape out or video out to a input on the other amp, then turn off the speakers on the amp you don't want to use and select the input of the amp you want to use.

  5. I wouldn't advise it. I don't understand why you need both hooked up to the speakers?

  6. First of all, why would you want to do something to your (excellent choice of speakers) speakers which it was not designed to do? if it's simply a matter of wanting to switch sources so you can be listening to the Amplifiers source material or the AV receivers source material then yeah get a apeaker selector but get a good one! might I recommend the Speakercraft SL-one.

    Before you go connecting things though, read your manuals and do more research….. Treat your equipment with care.
