One is that they usually have common ground. Then do the same for the other amp. Now to your specific situation. That’s because you have two different responses partnering up to create one huge stack of tone. Have you any suggestions? In that scenario, the connections from the amp binding posts to the outer rows of the first switch remain the same; the first switch’s connectors marked SP XX in the above table (the middle row) are connected to the corresponding connectors in the second switch, and the outer rows of the second switch are connected to speakers binding posts for two sets of speakers. I’m afraid the first 4 options would not work One reason is that it’s quite likely they all have common ground. Many years ago my late dad connected a Klipsch Heresy speaker to two Klipschorns for a center speaker. The second receiver, Marantz 2252, Using Channels A & B (same speakers), but no subwoofer. I just want to know the best way to hook up a single speaker to a 2 channel amplifier so as not to damage the amplifier. You might want to upgrade your home theater system with outboard amplifiers, or you just want your home stereo system to play louder and sound better. 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. For example I want Auxiliary #2 on Receiver #3 through speakers #5. you get the idea. The whole process (including making the enclosure) took us about two hours. If wired in reverse, will any of this product accomplish the same as your build? 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. 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). If you do that, first check whether (and how) this dummy load affects the sound. Wiring these volume controls is fairly simple. That covers amps and stereo speakers. Going to attempt to build one of these asap. Yes, the contact points of the 4PDT toggle switch we used in our switch box can accomodate a 16AWG cable. I’m not sure how this works as my electronics knowledge is very limlted. What is “bridging” an amp? The most expensive part was the speaker wire binding posts – the white ones cost $12. 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. So I’m wondering if with all these connection points there is sufficient contact area at each position 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). Hey there, I am Timothy and I am an aspiring bass guitarist and lover of high-quality speakers. And ideally it would allow to switch from any to any device (say from amp no. The surround sound processor is one of the most important parts of any home theater/audio-visual system. I guess what I am asking is if one were to do an A/B test on amplifiers with the same source and speakers, using your switch would still require the tester to manually switch interconnects (linking source to amp), right? We earn a commission if you click this link and make a purchase at no additional cost to you. Bridged mode capability is a special design feature in which a “push-pull” set up is created: one channel (normally used for the left speaker) produces a signal that’s the opposite of the second channel (normally used for the right speaker).. Never thought to two amp simply hook up with the most part, choose a general rule, does not the master amplifier and. 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. 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. contact area at each point to match the cross sectional area of say a 16AWG cable ? What sort of switchbox was it? The way that you wire your head unit to your amp will depend on the outputs on your head unit. Common ground is not a problem with turntables in most cases. In (A out) i have 2ohm total & in (A+B) i … To bi-wire your speakers, first remove those jumpers and use two sets of speaker cables. Connecting two amplifiers takes only three basic steps: Run speaker wire from the back of one amplifier into input A on the back of the switch box, making sure to connect right to right and left to left, and positive to positive and negative to negative. I understand that your situation is the second scenario. By the end you should be using one source, divided to two amps, to power four speakers. 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. Good luck on your project. 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. Switch 2: 2 inputs, 1 output. Attempt any sort of special wiring to run amplifiers bridged, in parallel or in series. Also make sure that you have the correct source selected. All I have to do now is move the little box from It makes great sense to share my front L/R speakers between the two setups. I was thinking more of the contacts made inside the switch when the toggle lever is thrown to one side or the other to select either amp-A or amp-B. Sometimes a protection circuit will trip, cutting off power or audio signal, and you might just need to turn the equipment off for a moment to let it reset. One channel hooked up to the speaker and one channel not connected. This was one of the three methods you can use to split 1 RCA jack into 2 RCA jacks and connect two amps. In this application, the two outer rows are for amps. My amplifier/hi-fi rack is close to the wall so it’s a pain to get get behind them to switch cables. 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, This one seems a bit different https://www.monoprice.com/product?p_id=8231&gclid=Cj0KCQjw9NbdBRCwARIsAPLsnFY3irQDDTwoTY2nCMGMrJqjC3JZGhr5XVCGtgZnLWA7odr7z3nH4ecaAkCBEALw_wcB. 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. By mentioning contacts I wasn’t referring to the screw terminals on the switch to witch the wires The speakers should have separate inputs for high and low frequencies, not just one pair of speaker wire connectors, or there should be a separate subwoofer in its own box and with its own connectors. Hope that helps. The output connectors for the speakers and subwoofer are on the back panel of the receiver and are clearly marked. But can be a problem if it is an amp selector. 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. 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. I wrote it in response to an earlier question, so let me quote myself: If you want to use this switchbox with a tube amp, it is quite likely that your amp should not work unloaded (with no speakers connected to it. If this is the case, wiring becomes a little bit more complicated, but it is still quite easy if you just take it step by step.eval(ez_write_tag([[468,60],'speakergy_com-large-mobile-banner-2','ezslot_5',114,'0','0'])); The home theater receiver will have a clearly marked section on its back panel where the “pre-out” outputs from the surround processor are. 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). Then run a speaker cable from the volume control to each speaker. It needs to be a “break before make” type (break connection to one amp before making a connection to the other amp) to prevent both amps from being connected to each other even for a split second – it should make it absolutely impossible to select both amps at the same time. 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. The cables from each amp are connected to the respective jacks for amp-A and amp-B via a bare Some higher performance amplifiers even have two sets of speaker connections to make it easier to connect things up. I just came across this project for two amps to one pair of speakers switch box which I’m interested in building. But, or at the other amp for two amps. I connected two 4 ohm speaker in series to A speaker out) , & connect 8 ohm speaker series with 7.5 ohm woofer added to : (B speaker out). Your guidance is much appreciated! a speaker switch and modify it? Hope that’s clear enough. So do I understand correctly that you were using a different switchbox before and it was sending your amp into protect mode? I think I would try to do something very old-school instead, a manual solution. The set of speakers includes : 2 columns (high-medium), 2 bookshelf speakers (med-low) and one subwoofer. Speakergy.com also participates in affiliate programs with Bluehost, Clickbank, CJ, ShareASale, and other sites. If you do that, and then turn on both amps, you will fry at least one of them, possibly both. Mounting screws and/or glue.
