how to hook up two amps to one speaker

Widely, In case of questions please contact us at: hello @ speakergy .com. speaker jacks. no additional electronic wizardry was needed thus very minimal interference with the music signal. With this switch box there would be suitably short cables (16AWG or other) from the jacks of the two Amp A and Amp B are connected to the inputs of switch 1. Parallel means sending one output of the bass amp head to one cabinet and a second output from the head to another cabinet. By the end you should be using one source, divided to two amps, to power four speakers. Is this what you meant by “splitter”? Here’s what it needs to do: 1. First, remove the jumpers that connect the two sets of inputs on the speaker’s back panel. The only commercially available switch I know that does all that is Beresford TC-7220. They can be on at the same time and you can switch between amps without having to turn them off. I have a question. I’m afraid the first 4 options would not work One reason is that it’s quite likely they all have common ground. If it’s a passive or active “pass through” subwoofer that you connect to the speaker outputs of an amp, and then connect stereo speakers to the subwoofer – you can connect it the same way to one set of outputs of switch 3. Plug the other end of the speaker cable into the speaker cabinet. By the end you should be using one source, divided to two amps, to power four speakers. This solution (2 separate switches for speakers A and speakers B) will work perfectly fine in other scenarios, for example with 2 stereo amps that use speakers A and B, or with a stereo amp and a surround receiver where the speakers are connected to front A and front B outputs of the surround receiver (as opposed to its front and rear speaker outputs). All I have to do now is move the little box from It needs to switch all 4 connections: L+, L-, R+, R- separately (no common ground). 3 sets of stereo speaker binding posts Sure, but it’s overkill. Make sure all of the equipment is turned on, and that the volume controls are turned up at least a little. Thank you for your response Rafal. Run speaker wire from the #1 output connectors on the back of the switch box to your pair of speakers, again making sure to connect right to right and left to left, and positive to positive and negative to negative. Connecting multiple amps to your hi-fi system like this can offer many advantages – more volume and more musical energy, better clarity and sound quality, deeper bass and less distortion and coloration all across the musical spectrum – from the highest notes to the lowest. It is possible to “bridge” amplifiers in this way in a car stereo system, but for home or professional audio, it does not work, and should never be done! and most convenient solution for me. I decided to go with a simpler but less convenient solution. Another problem is that many speaker switches have protection and/or impedance matching circuits, and those could also affect sound quality, so you do not want that. The row in the middle is for speakers. 1. The resistance value of the resistor depends on your amp’s recommended speaker impedance. When you hook up more than one speaker to an amp, there are two ways they can be arranged: in series, or in parallel. 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. Then run a speaker cable from the volume control to each speaker. If you have the skills, it’s much cheaper to build one. Black Friday / Cyber Monday 2021: Best Amazon Deals on Speakers, Smart Speakers and Headphones. Then, check the back of the amp to find its impedance range. Even the simplest process can go wrong, and finding the reason can sometimes take longer than the process itself. Have you any suggestions? Sony SB-5335, Pioneer U-24 Onkyo u30 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. with holes for the jacks. You should always turn your receiver or preamplifier on first, and only then turn your power amplifier on. 2. The steps below will exactly explain how to connect multiple amplifiers to the AV system. This switching box works for either two amps connected to one set of speakers, or two speaker sets connected to one amp. That would also require serious skills, but seems easier to design and implement. I don’t want any modifications to sound or tone I just want to switch between the components. Thanks for this post In this application, the two outer rows are for amps. 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). My concerns were one of multiple connections in the music chain and a believer of as few as possible … Sony System Selector MKII, Technics Model 103, The output connectors for the speakers and subwoofer are on the back panel of the receiver and are clearly marked. Good luck! So thanks again for your very informative article . Aug 30, 2009 #5 You can only share speakers between two amps if you use a switch that guarantees only one connection at any time (including during throw). Now run speaker wires from each amplifier to its corresponding speakers, making sure, when appropriate, to connect the left speaker to the amp’s left speaker output and the right speaker to the right speaker output. The surround sound processor is one of the most important parts of any home theater/audio-visual system. 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? Let me know if you have any more questions and good luck! 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). This way, I can switch the NAD pre-amp for "CD" to listen to 2-channel audio, exclusively, thru the NAD pre-amp/amp combo, to the Energy RC-30 fronts. 5. 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). Some higher end home theater systems might also offer separate output connectors from the surround processor, so that you can bypass the internal amplifiers and instead connect separate amplifiers – which may offer more power and better sound quality. It’s not ideal because splitters may slightly affect sound, but even if they do, they affect it the same way for both amps. Great article! What if you have followed our instructions exactly and it still isn’t working? You can see on the back panel that there are connectors for two amplifiers (marked “input”) and connectors for two pairs of speakers (marked “output”). 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). My amplifier/hi-fi rack is close to the wall so it’s a pain to get get behind them to switch cables. There are only 2 options for connection. he had old school tube amps. Then feed the other the right signal in the same fashion. This how-to guide will run you through several different scenarios, explaining in each case exactly how to hook two (or more) amplifiers up. 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. https://www.amazon.com/Stereo-Speaker-Selector-Switcher-Combiner/dp/B00CZNXKRA – I feel like this one might be the closest device to yours. So I’m wondering if with all these connection points there is sufficient contact area at each position This is what I would hook the floor standing speakers to. That covers amps and stereo speakers. Less convenient than with a switch but still a suitable This includes not just the amplifiers, but the receiver or preamplifier they’re plugged into and any source equipment you are using – CD, DVD or MP3 player, internet source, record player or anything else. I’d say do some research first. Nice information, I had experienced the difference. I’ve got a display wall of all of the early Mac tubes (49-70) which don’t have the issue of risking damage without load. 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. I've owned several high-quality speakers over the last few years and have become obsessed with them. ), 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. I know it’s very 19th century, but it might just do the trick. 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 compare a solid state amp and a tube amp, in most case these differences should be big enough. I used one of these switches for a turntable in my decent (but not hi end) system without any problems or audible signal loss. Thanks a lot for taking the time to answer my query. to the speaker. I then succumbed to my lack of skill in building etc – my soldering skills are non existent and not too competent so the credit card was broken out … I bought a DYNAVOX AMP-S. I don’ t know if you’re still updating this helpful thread. https://www.kjell.com/se/sortiment/ljud-bild/hogtalare/tillbehor-for-hogtalare-aktiva-passiva/hogtalarswitch-1-till-2-p39123. OK, my question is pretty simple but I want to make sure. It will damage your amplifiers, speakers, and possibly other components in your sound system. It will be to select either IMPORTANT!eval(ez_write_tag([[728,90],'speakergy_com-large-mobile-banner-1','ezslot_2',116,'0','0'])); When turning equipment on and off – especially power amplifiers – it is important to turn them on and off in the correct order. Wait at least two minutes before turning the Standby off. Try asking the seller, maybe you’ll get a clear answer. 1. This is my how-to video for hooking up a guitar amp to a 1960A Marshall Lead 4x12 speaker cabinet with the MONO/STEREO selector switch. I could build something but do you know if there is any gear that does this already. But i still think building a switchbox with a toggle switch is overkill for switching the source-amp line (including turntables), considering that a simple AV switchbox does the job and it’s very cheap. There are also Aiwa and JVC system selectors with amp switching function. The output of switch 2 is connected to the input of switch 3. If using a combo, ensure the speaker lead is connected to its socket on the back panel. In that case, the best solution is to use two switchers like the one I described. If any of your amps can’t handle that, use the safe switch (like mine). 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. The connections are now complete. To use Dual Audio, pair the phone with two speakers, two headphones, or one of each, and audio will stream to both. Hi, there. However needs must and reading your excellent article realised that the simple switch/wiring ie. The second and third apply when you want to connect two or more amplifiers to your system and use them at the same time, each amp powering a different set of speakers, with one of them usually used for a subwoofer. 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.
