If you have 2 amps but only 1 set of speakers – here’s the solution.

And you don’t need to build, wire or blow anything up!

I have a 5.1 surround sound speaker set up connected to a Yamaha amplifier. The problem is the two Q Acoustic Concept 40’s floor standing speakers I have sound amazing, so I would like to be able to listen to them in stereo only. This isn’t the problem as I can switch the Yamaha HiFi amp to Direct and get unadulterated sound through the amp to the Q Acoustics. The thing is, I have an older Denon HiFi amp that is just a stereo amp, it doesn’t even have HDMI inputs or surround sound it’s so old, but it does sound really tasty in stereo. It has a rich, full, bottom end that I know the Q Acoustic Concept 40’s would sound amazing with.

So the problem is how do I run one set of speakers using two different HiFi Amps?

  • One for when I am watching movies in surround sound and..
  • One when I just want to listen in stereo to the floor standing speakers.

I’ve googled this over the years and it seems not very many people have this question. I expect because most people are happy with one amp and one set of speakers. It’s only the audiophile-obsessed types who consider such a setup it would seem.

This is definitely a common issue for people who have a turntable/record player/phono stereo and a separate home theatre amp set up.

Specialty AV-71 Amp switch for 2 speakers pairs and 1 amp
Editor’s Pick
Of all the models listed here the Specialty AV SP-71 is affordable, does a simple task well and is great quality. Set up is easy and it does what it says.

Important things before wiring up your amps

The most important thing when looking to set this up is NOT TO wire everything together and hope that if you turn on one amp one it will power the speakers and then turn that amp off and turn the other one on to power the full 5.1 Dolby Digital surround sound set up.

This is asking for trouble and you are going to blow something, if not the speakers then one or both of the amps.

The thing you need to ensure is that when one amp is powering the speakers the other one can’t be connected in any way.

Fortunately, there have been a few companies come to the rescue in making switches for this exact purpose. Both offer ‘disconnect before connect‘ switching allowing you to change from one amp to the other via a switch, without the risk of blowing up your stereo. One offers more options with extra speaker poles.

Amplifier switching product options for multiple amps with single speaker pair

This first product is in such a rare space it doesn’t even have a ‘name’ although the actual model number is SP-71. The product title is: 2-Way Amp Amplifier Receiver to 1 One Pair of Speakers Selector Switch Switcher Splitter Combiner

1: 2-Way Amp Amplifier Receiver to 1 One Pair of Speakers Selector Switch Switcher Splitter Combiner – Specialty AV SP-71

This product is available online here and ships internationally. It comes from a brand called Specialty AV. You’ll have to wait a while for it to be delivered as it seems to go ground but it’s worth the wait.

It’s the most affordable option in this space that looks robust enough that I would trust my stereo system with it. This is the one I chose as I don’t need anything fancier. It allows a simple configuration:

  • One set of speakers to be connected
  • Two amplifiers to be connected
  • You can run individual speakers off individual (separate) amplifiers (not sure why you would want to but…a/b testing?)
  • Takes up to 12 gauge wire
  • This unit has a power rating of 100w (or 200w RMS). My Yamaha RX-V373 is about 100w per channel and the Denon is rated at 50w (although it sounds more like 100w it’s so big).

The second option is more expensive but offers more control

2: TC-7220 2-Way Amplifier Speaker Selector Switch Switcher Comparator Crossover Router

This TC-7220 unit available here has been around as a standard for home HiFi enthusiasts for a while. Like the Specialty AV unit, it allows switching but it’s a little more advanced (and a touch more expensive).

The TC-7220 allows the following:

  • Two amplifiers can be connected
  • Two sets of speakers can be connected
  • You can switch between speakers and/or amplifiers. You might have two sets of speakers and two amplifiers in your living room that you want to multi-switch between.
  • You could run two zones also. Have a set of speakers in your office and one in the lounge and change the speakers using the switch, and the amps as you like. This would require having a wired set up though which sounds a little like hard work.
  • Takes up to 12 gauge wire (same as Specialty AV unit)
  • Power up to 200w RMS (same as Specialty AV unit)

3: Dynavox AMP-S Amplifier/Box Switch Black (UK Only)

The Dynavox AMP-S available here seems to only be available in the UK. We’ll list it here for those of you who can get access to it. It’s nothing more or less special than the previous 2 recommendations.

  • Has the same rear poles as the SP-71. 1 x stereo speaker cable connection and 2 x 2 stereo amp connections.
  • No load is sent to the ‘off amp’
  • Easy rotator dial to choose which amp
  • Terminal poles are a screwable type to secure your speaker and amp wiring
  • 3 way switch has a ‘both off’ setting in the middle. Also means a full off before on connection when changing.

That’s about it really. The overall set up is pretty straight forward. These don’t require power so it’s easy to get them wired in quickly and off you go.

Big sigh of relief and endless thanks!
Sometimes a small sticking point can become a source of great frustration. At the cost of stretching your hospitality, are there any devices with more than 3 amplifier inputs?
Thanks and cheers.

Great job and thanks for your service. You have saved a lot of music lovers a world of stress. My wife says “WHY”.. I say because I should be able to. Lol. I have an Onkyo 7.1 surround for TV and now temporarily for music in my upstairs den. I am moving my old Pioneer SX 1080 upstairs but want to pair some old Misubushi speakers in with the Bose 901’s that are connected now. I did a test and the hi sound of the Mitsubishi speakers and the reflecting sound of the Bose us amazing funneling out of that… Read more »

Hi , First thank you for the post it is really interesting and just what I am seeking, I have a relatively low budget but still want to add great 2 channel audiophile quality to my budget home theatre.

I find it hard to believe that someone or some company hasn’t come up with a proper solution to this ‘problem’ long ago.
I’ve been searching on and off for a good few years for this. I’ve got a very nice Hi Fi amp plus an AV amp and rather than having 2 sets of speakers, I just want 1 set with both amps powering them with some kind of switch isolating the 2 amps.
Surely it must be a common problem?

I’m still not happy with the choices out there (which is almost none). For one thing, have you ever looked inside one of these boxes? There’s about two dollar’s worth of parts and technology in there. The enclosure is worth about another two bucks and yet they sell these things for way too much money. I’d rather look into making my own. It’s not that complicated.

How does this work for a system that has say a subwoofer for the home theatre side

Don’t you think there should be a word of warning for those who want to use either of those switches to select between solid state VS tube amp. Tube amps always require a load when they are turned on. Switching to a “B” solid state amp would blow the “A” tube amp if left on. Do you know of a switch that has an integrated solution to this problem?
