speaker switch 2 in 1 out

Posted 0 comments

Hi, there. $64.99. We expect that with normal use (1-2 flips per day), such a switch should work properly for at least 5 years. Is this what you meant by “splitter”? I want to run my old Marantz and Phillips turn table thru the same speakers as The Denon powers the CD player, tape deck and dvd player. Then do the same for the other amp. When you say Y -splitters, do you mean a switch? I think there is a good chance that the ground is switched in this one, but I can’t be sure without testing it. That’s it all done. within the switch suitable for the guage of cable being used. $19.99. You can choose to utilize speaker one, speaker two, or both speakers simultaneously using the button selectors. More importantly, they have the A+B selection possibility, which is what you select if you want to fry your amps (it would connect amps to each other and fry output transistors). If you want a switch that will accommodate two amps and two sets of speakers (exactly like the $120 Beresford does), you will need one more 4PDT switch and one more set of stereo speakers binding posts. But I would have to see its internal wiring to confirm that it does not have common ground. He was careful, but his daughter wasn’t. And you’d have to use plugs that fit in sockets only in one position. Yes, the contact points of the 4PDT toggle switch we used in our switch box can accomodate a 16AWG cable. $437.98 Your price for this item is $437.98. It’s not certain, but it’s simply much easier and cheaper to build a selector with common ground and it is not a problem if it is is a speaker selector. The quality of components if as poor as can be expected, but there are no wires, so it should primarily affect the switch durability, not signal quality. Try asking the seller, maybe you’ll get a clear answer. The whole process (including making the enclosure) took us about two hours. There are two possible scenarios: 1. I see no reason why not do you? If I open this unit and modify it following your instructions for a Tried that too, but it’s inconvenient if you switch often (I do). amps going to the respective input jacks in the box. Question solution in my case. If it has a different connection method, I’d have to know the details. As far as power rating goes – higher is better, best to match or exceed your amp’s rated power per channel, definitely do not use anything below 10W. I have a TV hooked up to good quality stereo speakers through an amp. This switching box works for either two amps connected to one set of speakers, or two speaker sets connected to one amp. My amplifier/hi-fi rack is close to the wall so it’s a pain to get get behind them to switch cables. One switch switches speakers A, the other switches speakers B. If wired in reverse, will any of this product accomplish the same as your build? Using the same principle that you’ve described for 2 amplifiers and 1 pair of speakers, That’s much more than speaker protection fuses in most amps. Hi Remigiusz, You do not want to have common ground between two amps, this could negatively affect their performance (and sound quality) and in some cases also case damage – there are amps that have fully balanced outputs and cannot have common ground between speaker connectors, for example some Class D amps. ... Model: SDB-2.1. I’m following your switch diagram but since I have a “mono” set up, can you provide a diagram for making a 2 input 1 output mono setup? Note that in some rare cases this connection (source connected in parallel to 2 amps) could cause sound degradation. Here’s what it needs to do: 1. The audio does not switch to the headphones when they are connected to a Dell computer using the Realtek High Definition audio driver. In short, I would not use any of these switchboxes to switch between amps. Switch 3 selects speakers A and/or B. Amp C and the output of switch 1 are connected to the inputs of switch 2. I really appreciate your insight. Ouch... You have clicked a page that seems to be very popular. – what would be the schema to make it. But most importantly, most (actually almost all) of these switches allow to select more than one set of speakers at the same time – which becomes selecting more than one input amp when you use the switch in reverse. The headphones jack is not enabled by the Realtek Audio drivers On a Dell computer, which uses the Realtek High Definition audio … on Introduction. After much reading I decided on an Amp switch box – this being the simplest and most effective solution. https://www.amazon.com/Stereo-Speaker-Selector-Switcher-Combiner/dp/B00CZNXKRA, https://www.firefold.com/stereo-2switch?gclid=Cj0KCQjw9NbdBRCwARIsAPLsnFZsZw8vn3YmlP2yhEH3RpnuOZEPaccx-JE-zKMrF6DJHOwPyEoXKu4aAipXEALw_wcB, https://www.amazon.com/Stereo-Speaker-Selector-Switcher-Combiner/dp/B0184M4TVQ, https://www.amazon.com/Switch-Stereo-Receiver-Speaker-Selector/dp/B00YNUICRQ/ref=sr_1_fkmr1_2?s=electronics&ie=UTF8&qid=1538688845&sr=1-2-fkmr1&keywords=ab+stereo+speaker+selector, https://www.monoprice.com/product?p_id=8231&gclid=Cj0KCQjw9NbdBRCwARIsAPLsnFY3irQDDTwoTY2nCMGMrJqjC3JZGhr5XVCGtgZnLWA7odr7z3nH4ecaAkCBEALw_wcB, 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, http://audio-room.net/pro-2-sp-200-source-amplifier-switch-gallery/, https://ae01.alicdn.com/kf/H6f0d6bc384d34f68acb17d4ae196734aT/2pcs-1-Male-to-2-Female-RCA-Cable-Adapter-Connector-RCA-Y-Splitter-Audio-Video-Plug.jpg. My way of switching is safe for both amps and speakers, so it can be used also in your scenario. a speaker switch and modify it? amps to the speakers. My dream is to be able to select an amp (or set of mono blocks) to listen to on my main system from a central wall mounted switch box. That would also require serious skills, but seems easier to design and implement. It’s not ideal because splitters may slightly affect sound, but even if they do, they affect it the same way for both amps. Looking at the inside I was pleased to see it very much resembled your creation above – simple switches, connectors & wiring. Passive device, Simple and do not have to worry … The first receiver is Surround-Using Channels A & B, + Klipsch Subwoofer. Parts Warranty: 90 … Of course, toggle switches can also be used for this purpose. Hi Harry, One switch usually makes no difference, several switches could audibly degrade sound. That, of course, is not preferable in the case of signal from a turntable, which is very weak to begin with. Required fields are marked *, +  For example I want Auxiliary #2 on Receiver #3 through speakers #5. you get the idea. set of jacks depending on which amp is being used. We used speaker wire to connect the binding posts to the switch. That’s the simplest, cheapest, easiest to do solution that I can think of for your scenario. For turntables, I strongly recommend a passive switch (active switches are likely to add hum/noise that would be amplified by the phono stage, resulting in a very high noise level). The set of speakers includes : 2 columns (high-medium), 2 bookshelf speakers (med-low) and one subwoofer. Hope that helps. To accommodate subwoofer I would have to know what kind of subwoofer you’re using and how it is connected to each of your amps.

I think I would try to do something very old-school instead, a manual solution. 2. Test all connections after soldering for conductivity and possible short circuits between connectors. For speakers, you can daisy-chain a few switches like the one I’ve built to switch between amps (remember that break-before-make and no common ground are crucial here), and then connect their output to a commercial speakers switch to switch between several pairs of speakers (these switches can have common ground and allow multiple connections at the same time unless you’re using tube amps, class D amps or ones that can’t handle low impedance speakers). 5. With a switch that meets all the above conditions, you can safely connect two amplifiers (or two receivers, or an amp and a receiver) to one set of speakers. … If you short connectors you will fry your amp, so be extra careful. Hello. I’d say a passive, mechanical system is out of the question unless you are a mechanical engineering professor with a group of eager students who would jump at the project. You can select only one position at the same time. When you’re doing A/B test to compare 2 sets of amp using the switch connected to the same set of speakers, are you using the same source (eg CD player) ? We cut the missing wall from plywood and made holes for binding posts. It wasn’t easy to catch it safely with these smallish screws, but doable. Also, putting an attenuator (volume control) in line is a good way to degrade the sound, so I would not do that. Thanks! I’m not aware of any single device that would do all that. 3. But whether such a switch degrades the signal could vary depending on the quality of the audio system (there could be an audible difference with a hi end system – just like with better and worse quality cables). 3.5 out … Or you simply want to quickly compare 2 amps (like we do very often here at AR), A/B test them without having to make long pauses for switching the amps off, disconnecting speaker wires from one amp and connecting them to the other amp. User rating, 4.3 out … SKU: 1519568. 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. £11.00. I just came across this project for two amps to one pair of speakers switch box which I’m interested in building. Thank-you very much Rafal. User rating, 5 out of 5 stars with 1 review. So I’m wondering if with all these connection points there is sufficient contact area at each position Thanks for the reply. The simplest and cheapest option is to built a switch box using a 4PDT switch. We used an enclosure of a nice-looking but crappy speaker as a housing for our switch. A 4PDT switch has the right number of connections (L+, R+, common ground, turntable ground). I used an on/off/on switch so I've got an off too! If I build this box to use, only one amplifier will be powered on at any time. I don’ t know if you’re still updating this helpful thread. It selects between Amp A and Amp B. 5 out of 5 stars (3) 3 product ratings - Stereo Speaker 2 Way Switch Box Splitter/Selector for 2 pairs of speakers. The cables from each amp are connected to the respective jacks for amp-A and amp-B via a bare The speaker cables are then plugged in to each Unless one of your amps does not tolerate that, in that case it is better to use my (safer) switch. Switch 3: 1 input, 2 outputs (this one can be ready made if all your amps can handle common ground and more than one set of speakers connected at the same time). The row in the middle is for speakers. We installed the switch in the opening left after removing the bass tunnel. We use identical cables (same brand, model, length) for connections to both amps and we switch these cables mid-test to exclude any differences between cables. Therefore, you would only get to choose 2 of the 6 channels to pass … They can be on at the same time and you can switch between amps without having to turn them off. But it does mean two times the work, materials and time needed to build the switcher. ), use recordings you know very well and fairly neutral-sounding speakers, you can compare amps without a switchbox (with breaks needed to change connections) and still catch most differences between amps – as long as they are not very similar. under the rack to switch the speaker cables. Is it possible to use a speakers selector switch in reverse for this? Details about 2 in 1 Out or 1 in 2 Out Audio Source Signal Selector, Switcher, Speaker, AuX3F9. Have you any suggestions? (1) Price Match Guarantee. 1. The result is a functional, safe, and aesthetic switch that allows to safely connect two amps to one set of speakers and switch between them even when the amps are on, just like the $120 Beresford switch, but ours costs only $22 in parts (again including the cost of speakers that we gutted to make the enclosure). Also, one of your amps is a stereo receiver (the same signal goes to speakers A and B) and the other amp is a surround receiver (different signal goes to speakers A, different to speakers B). I’d say do some research first. I use my high power tube amp Can choose 2-IN-1-OUT for 2PCS amplifiers+1pair speaker, or in turn 1-IN-2-OUT … A tube amp just arrived and I’m looking forward to hooking it all up. Answer single switch and remove the second switch this would be the cheapest So, again, is it safe to connect two amps to one set of speakers? Your guidance is much appreciated! 3 sets of stereo speaker binding posts .hide-if-no-js { It’s currently a bit busy. I looked at the photos of the inside and Dynavox AMP-S looks good, it has a different type of switch inside, but according to product description it does switch ground as well. That is also important. All other standard return policy conditions apply.. Close Did you make this project? Really Simple Audio Switch (2 Inputs, 1 Output): This is a project developed during our "Taller de Inventos" (AKA August Build Night), sponsored by Instructables and Jameco, that provided some of the components for this instructable. Depending on the type of switch and binding posts, you might need solder wire and a soldering iron to connect internal wiring. Thanks. I have a computer generating music supplying a mixer to broadcast to hospitals. I take seriously your warning about using this switch with a tube amp and the problem of a “no load” condition.  =  Find multizone speaker switchers that let you select speakers in any room. The easiest way to do that by ear is to connect the source to both amps via Y splitters, play through one of the amps, and disconnect only cables going from the Y splitters to the other amp while listening. If you have more questions, drop me an email, and let me know when you’re done, I’ll be curious to see a photo of you switchbox (whether you build it or convert the one you’ve linked). If you use this type of switch box with tube amps then yes, to be on the safe side only one amp should be powered on at any time and it should be selected (with the switch box) before you turn it on to ensure that the amp is not on without load. Free postage. (11 total- 8 stereo pairs, 3 stereo amps). You use either speakers A or speakers B (but never both at the same time) with each receiver Connecting multiple amp/receivers to one speaker pair as amplifier selector. Switch 1: 2 inputs, 1 output. So before doing an A/B test, make sure that the sound from source is not affected. 2-Way Amp Amplifier Receiver to 1 One Pair of Speakers Selector Switch Switcher Splitter Combiner 4.8 out of 5 stars 127. A very informative post – thank you ! High isolation prevents signal leakage that could cause interference. You can have a rest and please slide to verify. Make sure that yours can before you use it with a switchbox – it effectively disconnects speakers. If your amp does have to have a load to be operated safely (or this information is not available), a possible workaround is to use a dummy load – a resistor connected in parallel to the amp’s speaker outputs. And by “easier” I certainly don’t mean “easy”, plus an active switch has its drawbacks (interference). 4 years ago. Remember that my switches can work both ways, this means that they can have either 2 inputs and 1 output or 1 input and 2 outputs. Drill the necessary holes on your box for the jacks and the toggle switch. 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 Free shipping. 8 in 1 Out 3 RCA AV Audio Video Splitter Amplifier for Cable Box DVD DVR Analog TV 1x8 Port Splitter Composite 3 RCA Av Video Audio Switch Switcher (8 in 1 Out) 4.3 out of 5 stars 353 CDN$26.99 Managed to put a switchbox together this afternoon and It works a treat, no more ‘protect’ mode.

But bear in mind that the more switches you add to the signal patch, the more sound quality you will lose. 6-Way Stereo Speaker Amplifier Switch Selector. Amp A and Amp B are connected to the inputs of switch 1. 14 Unfortunately there are no simple, sturdy and cheap mechanical toggle switches (that I can find) that would allow to switch a total of 8 separate signal lines (and that’s how many you get with 4 speakers), which is why you need a separate switch for each pair 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. Speaker … I could build something but do you know if there is any gear that does this already. Unless it doesn’t work (or causes signal degradation) in your system. MK-1 A-B Audio Switch Box : 2 Input 1 Output Selects Two Inputs to One Output Now you can Easily Choose between your Audio Devices! Thanks for this post Assuming that your “old Marantz” and “The Denon” are amplifiers or receivers, the answer is yes. Here’s how we built one of them. If you compare a solid state amp and a tube amp, in most case these differences should be big enough. On top of that, it has impedance matching (also bad, unless your amp can’t handle a 4 ohm load and you have to use that. Exactly. One is that they usually have common ground. Passive device, Simple and do not have to worry about sound effect, pure DIY manual welding. The second receiver, Marantz 2252, Using Channels A & B (same speakers), but no subwoofer. Thank you so much for the knowledge you’ve already imparted. You see, I only need to switch my amplifiers a few times per year. So the the same switch box as you describe function for this set-up? 4. Eliminate the need to swap cables with this 2-way audio/video switch. Well, not really. 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. Thanks! With this switch box there would be suitably short cables (16AWG or other) from the jacks of the two I understand that in the case of the surround receiver speakers are connected to front and rear outputs, and not to front A and front B outputs (that would be a very different connection and actually similar to using a regular stereo amp). One potential problem is that the power connectors would be right next to signal connectors, so there’s interference potential, but if you use shielded cables, that’s only at the connectors. Thank you for your response Rafal. It will be to select either ... but the seller was very helpfull and quickly sorted this out. We used them only because they were already sitting in our drawer. BTW, our experience is that if you learn to listen for certain aspects of sound (like colouration, soundstage, clarity, detail, PRaT, etc. – do you think this would be safe, Regarding my original question, I now see that I wasn’t too clear in how I put the question. It’s not a big problem, you just flip 2 switches instead of one. Common ground between channels is not a problem with turntables, and you can use the 3rd RCA socket to connect and switch the grounding wire. I understand that your situation is the second scenario. In that case, the best solution is to use two switchers like the one I described. Separate switching of L and R channels is less convenient (you need to flip 2 switches instead of one), but works just as well. If any of your amps can’t handle that, use the safe switch (like mine). We use one source connected to both amplifiers at the same time via Y splitters. In this application, the two outer rows are for amps. Good luck on your project. If you do that, and then turn on both amps, you will fry at least one of them, possibly both. I disassembled 2 cheap passive AV switchboxes that I happened to have at home and I did not find any resistors or other components inside that would alter the signal, just sockets, a PCB with tracks and a switch.

That is, is there sufficient 1) Is this the right approach to eliminate pop?, if not please recommend another. Search for “AV RCA Switch Selector Box”. Switch 1, switch 2, switch 3. There are three problems with the majority of speaker switching boxes. The left Y-Splitter should be connected to both the left inputs of Amp A and Amp B. Now that I know what you meant by a Y-splitter, I just want to make sure that, if the source is a CD player, then I would need to have one Y-splitter for each of the RCA outputs (Left and Right). The perfect scenario would be to control the power from that switch as well so that as I switched one, it would power it up and cut the power to the previous. Common ground is not a problem with turntables in most cases. We broadcast 24/7 but being volunteers there are many hours when the mixer could be powered down and the music signal could go direct to webcast, but it is the switching that bothers me. Switch between Receivers, speakers, Aux, and phono. Using the same components? EMK Optical Audio Switch SPDIF Toslink Switch IR Remote 3 input 1 … There are much cheaper alternatives (both spring-type and banana plug ready) and if you use those, the total cost will be closer to $10. I have a slightly different question and want to be certain I have it right. Very happy with the result. Now to your specific situation.

And ideally it would allow to switch from any to any device (say from amp no. Or actually 2 switches like mine to switch between the amps and one cheap, ready-made speaker selector, because switching between speakers is a less sensitive issue and you can have both pairs of speakers playing at the same time and, unlike amps, they can have common ground. My concerns were one of multiple connections in the music chain and a believer of as few as possible … JIN20120119 Store. 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). Could this used to use one turntable with two amps subbing RCA jacks?
