Hi All,

I seem to be a bit backwards with this question so please bear with me.

I have two amplifiers
  • Denon 2809 Class D (120W Peak)
  • Classe CA-5200 Class A/B (200W RMS)

I have one set of speakers.

The Classe system consumes around 400W of power from the wall sitting idle (about 1500W during a heavy bass note at volume) so I want to use the Denon when I'm listening to pop music, watching movies, etc.

So what I need is a reverse speaker selector that will allow me to select which amp to use with my speakers (because right now the Denon is basically just being used as an HDMI switch for my Classe system, something I'd like to change).

Unfortunately, I can't just use a speaker selector because:
  1. I have yet to find a multi-source speaker selector that rates above 150W RMS (I found one with 2 inputs and 4 outputs - overkill but it still only did 150W RMS)
  2. A speaker selector is likely to have a diode in there to prevent a surge back to the input, so simply hooking my amps up to the speaker outs and the speakers up to the selector's input is likely to cook the selector.

Has anyone heard of such an animal?

Note: I never crank my system up to the 200W ceiling but I still want the headroom on any selector that I might buy.

Cheers,
Dave.

Well that's about as ugly as it gets but I guess it's fixable with a new project box. Thanks mate! smile.gif

If you intend to completely power off the other amplifier when you don't want to use it, then this one will do the job for you automatically...

I personally haven't used it, but it seems to cover your desires... maybe.

??? Why not use the pre-outs from the denon to fee dthe Classe amp?

And the amp isn't using 400w sitting idle.
