two amps one set of speakers
I understand that the subwoofer is not important because you only use it with the surround receiver and you only need to connect speakers A and B to two receivers. Buying the speaker switchbox you mention might be an option but: – that speaker switchbox costs almost exactly the amount we paid for all parts (including the enclosure) of the switchbox in our article, since then we’ve built another switchbox that was 30% cheaper because we’ve found cheaper sockets; of course that depends on the cost of parts in your area but you would still have to buy some parts you will need to make the conversion: at least a 4PDT switch and probably some wires; – you would still have a lot of work to do, you would have to replace the two switches that are there now with the switch we recommend (a 4PDT switch), and fitting a 4PDT switch in an opening left after one of those flat cradle switches might be difficult and it might turn out that you can’t fit a 4PDT switch with screws for wires (it’s quite large and might not fit in this enclosure) and have to use a smaller switch that you have to solder wires to – soldering 12 wires is more tedious; – you will probably still have to rewire the speaker wire connectors: this switchbox probably has common ground (they usually do) which is OK if you switch between speakers, but should be avoided if you want to switch between amps; – you would still end up with a switchbox that has poor quality wire connectors (these spring-type connectors in the back – we do not recommend them, they are a problem if you use a wire that’s too thick or too thin for them and they break more easily than even the cheapest screw-type connectors). Unless you’re running very expensive valve amplifiers I can’t see why this wouldn’t suit all home theater enthusiasts. AV RCA Switch Selectors can have resistors inside, which degrade signal quality. Sure, but it’s overkill. display: none !important; The resistance value of the resistor depends on your amp’s recommended speaker impedance. It seemed like a perfect pairing of an ancient technology with a brand new one. That’s it all done. Historically, only two types of speaker designs paired well with SET amplifiers. Mind the channels and polarization. Re: Two amplifiers to one set of speakers Post by tckmet » 27 Sep 2017 03:07 Just want to mention that most Merchants selling audio/video gear have this capability of switching between speakers and or amps… Your scenario would require a rather complex and heavy duty system, you’re talking about switching power (2 poles), line level input signal (4 poles) and speaker level output signal (4 poles), a total of 10 poles at the same time, break-before-make, between 11 devices. I’ve just found such a switchbox: https://www.amazon.com/Amplifier-Receiver-Speakers-Selector-Switcher/dp/B0796KGVXT/ref=sr_1_4?s=electronics&ie=UTF8&qid=1540735524&sr=1-4&keywords=amplifier+switcher&dpID=414UiX3FHhL&preST=_SX300_QL70_&dpSrc=srch One 4PDT switch or two DPDT switches (we recommend toggle switches) With this switch box there would be suitably short cables (16AWG or other) from the jacks of the two Power up to 200w RMS (same as Specialty AV unit).

The outputs of switch 3 are connected to Speakers A and Speakers B. No idea if the Denon has a similar function. It might have little or no effect (for example volume drop that can be easily corrected, you have to match volume of both amps anyway), but it might also alter the sound enough to make the amp sound worse. I had exactly the problem you describe in connecting an AV amp and a HiFi amp but room for just one set of main speakers. Hope this one does: I am a little confused because if you are using the same source, you would have to manually switch interconnects between the source and amp every time you toggle the switch ( to select your desired amp), am I right? The SP-71 or TC-7220 list here will solve the problem for you. Amp A and Amp B are connected to the inputs of switch 1. Channel L and R switched individually. Very happy with the result. The speaker must be designed to function in this way; in general, hi-fi speakers are not so designed. I’m using the speaker outputs A and B on every amplifier. Now that is a challenge. I’m not sure if I’ve explained that clearly – would it help if I did a diagram to illustrate? I have many receivers, CD players, tape decks, turntables, speakers etc… Need to be able to switch between them. Jabra Elite 85t vs 75t: Which one to Choose?
