how to hook up two amps to one speaker

Hi Harry, There are only 2 options for connection. If I build this box to use, only one amplifier will be powered on at any time. But we’re on the right track now: what you need is indeed a switch – but it has to be a specific type of speaker level switch in order to accommodate 2 amps. Otherwise, the Y splitter is a simple solution if you amplication does not have the features I mention. Hi, there. You might have two sets of speakers and two amplifiers in your living room that you want to multi-switch between. Going to attempt to build one of these asap. amps going to the respective input jacks in the box. There’s a numbers of reasons for trying to do that. Whichever method is chosen – I totally agree with you – you cannot tell the difference from a switched connection to a direct connection – to my ears anyway ! eval(ez_write_tag([[580,400],'speakergy_com-banner-1','ezslot_6',110,'0','0'])); This solution does not let you play both amps at the same time and does not increase power or make the system louder. Now to your specific situation. 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. Unless one of your amps does not tolerate that, in that case it is better to use my (safer) switch. Both channels to 1 speaker (APW says its a no no) 2. A possible workaround is to use a dummy load – a resistor connected in parallel to the amp’s speaker outputs. usually i use A speaker out only & somtimes A+B ! Never thought to two amp simply hook up with the most part, choose a general rule, does not the master amplifier and. Thanks a lot for taking the time to answer my query. 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. 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. My way of switching is safe for both amps and speakers, so it can be used also in your scenario. Sorry Rafal but I just realized my shortened link does not work. Glad my post could help. 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. He was careful, but his daughter wasn’t. The fifth option (Monoprice) is theoretically designed to work with 2 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). 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) ? Glad I could help! The resistance value of the resistor depends on your amp’s recommended speaker impedance. ... all he did was connect two speakers to the channel with the speaker … But can be a problem if it is an amp selector. Similar to a passenger on a small motor bike: add another passenger and the load the bike needs to carry is doubled, but most bikes will cope with two passengers.However adding more than two speakers will normally overload the amplifier. If you can’t figure out the problem, bring it to a qualified – preferably factory authorized – technician. Next, using a Y adapter, split your preamp’s center channel output between the amp’s left and right inputs and then use its left/right outputs to separately drive the speaker’s tweeter and midrange/woofer sections. 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. 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. The price is reasonable compared to the Beresford switchbox. Hello Rafal. dating in philippines. Using the same principle that you’ve described for 2 amplifiers and 1 pair of speakers, Obviously I only use one set at a time. }. Run speaker wire from two amplifiers to one set of speakers at the same time without using the correct amplifier switching box –. This is what I would hook the floor standing speakers to. Your email address will not be published. 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. wire connection in the holes for this in each jack. This switching box works for either two amps connected to one set of speakers, or two speaker sets connected to one amp. No load is a problem for many, but not all tube amps, so try to check which group your amp belongs to. Sound quality is not an issue. If any of your amps can’t handle that, use the safe switch (like mine). 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. Just one question. Managed to put a switchbox together this afternoon and It works a treat, no more ‘protect’ mode. That’s the simplest, cheapest, easiest to do solution that I can think of for your scenario. 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. 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. If you do that, first check whether (and how) this dummy load affects the sound. This was one of the three methods you can use to split 1 RCA jack into 2 RCA jacks and connect two amps. For this case, you want to put your speakers in series, so the total impedance of the speakers will be 8+8=16 ohms, matching the amplifier. This question gets asked a lot. In that case, the best solution is to use two switchers like the one I described. 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. There are only 2 options for connection. 2 receivers/amps, 2 pairs of speakers Utilizing Channels A & B. The steps below will exactly explain how to connect multiple amplifiers to the AV system. If any of the above would work, could you please let me know advantages/disadvantages vs. yours and Beresford TC-7220? Then, check the back of the amp to find its impedance range. a high powered or low powered tube amp. Hope that’s clear enough. Sure, but it’s overkill. Switch 1, switch 2, switch 3. I have a question. As a result, we had a nice box without one wall and with a round opening in the opposite wall. Locate the section on the AV receiver’s back panel that has the “PRE OUT” connectors. 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).. 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? To begin using your amplifier, connect the speaker lead to the cabinet and head. This exact thing happened to a friend of mine. 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). ), 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. If possible, connect each separate piece to other gear to see if it works, and replace cables with spares if you have them. amplifier output jacks to the speaker jacks. We will use a good basic and affordable amplifier and speaker switching unit for this tutorial, the Specialty-AV SP-22V. Tried that too, but it’s inconvenient if you switch often (I do). One is wired to the speaker. 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. If you solder the wires to connectors it’s best to isolate them with heatshrink after soldering. As far as wiring goes, you connect outer rows of contacts of each toggle switch to speaker wire connectors and the inner rows of contacts of each toggle switch to each other. As another holiday season approaches, it is time to think again about holiday gift-giving, and so it’s time to think about shopping and sales – and especially the incredible discounts, There are very few products on today’s consumer electronics market as hot and exciting as smart speakers. What Gaming Headset does PewDiePie use in 2021? It is not for music. One cable is for the bass, and the other one is for the tweeter. 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. Plug one end of the second unshielded speaker cable into the power amp channel two speaker output, and the other end into the woofer. I have just rammed the speaker wire from each amp into the speakers and am getting a perfectly acceptable result. with holes for the jacks. You would have to manually pull the plug from one socket and put it into another, but it would allow to switch all ten connections in one move, break-before-make. Could this used to use one turntable with two amps subbing RCA jacks? To bi-wire your speakers, first remove those jumpers and use two sets of speaker cables. By the end you should be using one source, divided to two amps, to power four speakers. But with switches of this type any change in sound should be minor or even inaudible. One 4PDT switch or two DPDT switches (we recommend toggle switches) You got the connections and internal wiring right, that’s exactly how it should be connected. If so, please consult our tutorial “How to Connect Two Amplifiers to a Mixer” for detailed instructions, helpful hints, troubleshooting and other information. Switch 2: 2 inputs, 1 output.

Of course, toggle switches can also be used for this purpose. You use both speakers A and speakers B at the same time with each receiver. I’m guessing there simply isn’t any workaround, which is unfortunate. set of jacks depending on which amp is being used. I used the video socket to connect (and switch) turntable ground. Example: You have two 8 ohm speakers you want to connect to an amplifier with an output impedance of 16 ohms. If you have a solid state amp – no problem. But, or at the other amp for two amps. 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).
