This is the part EVERYONE gets wrong. Many people think that if they have a speaker rated at 50 watts, then adding another 50 watt speaker will give them 100 watts of power. guitar---[(input---output)]---[(input---output)]---amp In order to use two amps like this in array, you need to mult the master amp's preamp out into two signals. Hooking amps together by jumpering the second input on a dual input amp to the input of a second amp is safe, but you can get a lot of noise from ground loops, and you can get phase issues if the two amps aren't phased the same. If each speaker has an impedance below 8 ohms, you should wire them in series. Using an ABY switcher is easy. The sound company handled the split from the Marshall to the Crowns, but I just fed the guitar (well, the pedal board output...) into one Marshall input, looped 2 and 3 together, and used 4 as the output feed to the split for the Crowns. I have two 60W combos- fender and Marshall- that I would like to connect together using one for distortion and effects and the other one will always stay clean and punchy. 3 tips to #connect multiple speakers to one amplifier to better sound.

I know I can buy a aby box but I would prefer to use the xlr out or effect loop out from one amp to the other and run my bass through both amp. Variation 2: Connecting to a Home Stereo Amplifier. The voltage available across amp’s bridged channels working together in a push-pull fashion is: Total voltage: 2 x 14.14V = 28.28V. Bad Idea. With few exceptions, combo amps come with one speaker for lower-powered models, and two for higher-powered models. One goes right back into the power amp in, and the other gets connected to the slave amp's power amp in. Chaining two amps together does not combine their output wattage, if that's what you are asking. Understanding the different pedal groups is the key to getting the best sound when chaining them together… They also lack the crunch needed for heavier rhythms. One way is usefull if you like the preamp of one amp but want the output secion of another amp either for it's tone or power. ie Instrument into the Hartke but utilising both stacks at the same time. Connecting a mixing board to a home stereo amplifier is basically just like hooking the board up to a professional PA amp. I would sell the two amps and buy a bigger amp (costs money tho'). Step 3. If each speaker has an impedance of 8 ohms or more, then you can generally connect them in parallel. Also, the equipment chassis are connected together by the shield of the audio cable coming from the direct box. The AB designates the ability to switch between amplifiers while the Y means that both amps can be turned on at once. Note that the information presented in this article is for reference purposes only. We send the guitar's output via a cable to one amp and running out of a #2 jack into another amp. We connect the same 2 x 50 watts/channel amplifier in bridged mode across one 4 ohm subwoofer. Connecting two guitar amps together is a technique that many veteran guitar players use to expand their sound. Figure 2 shows a ground loop.Two equipment chassis (guitar amp and mixer) are connected to two separate safety grounds by their AC cords.

A 4x12 cab is typically 16 ohms, so when you connect two of them together in parallel, the total load becomes 8 ohms. Buy a Y-cable with ¼-inch male end and two ¼-inch female ends. Summary of Connecting 2 speakers. Then, get patch cables to connect the pedals together. Taking a output from one amp and going into a second. Power across the 4 ohm subwoofer: V x V / R = (28.28)*(28.28) / 4 = 800 / 4 = 400W in bridged mode. By blending these two tones, you can achieve the best of both worlds. This technique allows you the ability to use two different-sounding amplifiers to create a fuller guitar tone. Plug the guitar into the the DI input, connect amp A to DI through and amp B to DI output, for example. I own a hartke 500 watt head into a 4 ohm 500 watt 4x10 cab and a LabSystems 300 watt head into a 4 ohm 800 watt SWR 4x10 cab. Many guys plug their axe into one amp input then plug another guitar cable into the second input and the other end into the imput of the second amp. How basic to connect multiple speakers to 1 amplifier in order. As has been mentioned...it is NOT a good idea to connect your stereo or surround speakers to your guitar amp.

While combo guitar amps offer many benefits, their only limitation is the number of built-in speakers. Then turn the amp on at a low volume and gradually increase to the desired level. You can divide the input signal into both amps. While many traditional amps come with two pieces of equipment called the head and cabinet, combo amps have both technologies contained in one easy-to-use piece of equipment.

Hopefully at least one of your amps has a "line out" jack in the back. Connecting Cabinets to Amplifiers . Kurt began playing guitar at the age of nine in Kalamazoo, Michigan. The "wall of Marshalls” is a semiotic signifier of all sorts of classic rock and metal “baggage” that a band might want to invoke. Amp (-) to Amp (-) These connections is what Physically ‘bridges’ the amps together! There are only really two ways to connect 2 speakers to one amplifier – either in parallel or series. You connect your guitar or the output from your pedal-chain to the ABY, and from the ABY, you feed the two amps. Speaker Power. You can find many guitar amps billed as "two channel" amps, but many of these are still intended to amplify only one guitar at a time. In many cases, you will have a number of speakers, and then you must calculate the “load” that the amplifier will need to support. 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). 2 - because of differences in the grounding paths for each amp, you'll probably get a ground loop hum For this reason the very best way to drive multiple amps is with a purpose designed box that will usually be active (powered) to boost the signal and have at least one transformer for complete isolation between the two or more amps. A home amplifier probably uses RCA connectors, although some higher-end amps may have balanced XLR connectors as well. Once you get a guitar and an amp, the next step is to explore effects. He is a guitar DIY'er and tube amplifier designer who enjoys helping other musicians along in the endless pursuit of tone. Effects pedals can be separated into groups based on their functions.

Reverb is used often in music production, and a reverb pedal will thicken your guitar’s sound by giving it an ambient trail, which is particularly great when used with clean settings on your amp. However, there is no guarantee the either amp will sound the same as it does on its own, because the input impedance of both of them coupled together (directly or though the transformer in the DI box) will be different, which may or may not affect the tone, depending on the guitar and the amps. If he was running three heads, assuming everything was normal inside the amps (as far as impedence selection, etc.) Other amps—like the airy open-backed Fender combos or the crystal-clear Roland JC120—have plenty of high-end sparkle with excellent attack and articulation on chords, but are too clean to generate much sustain. In comparison, half-stack amplifiers typically … This effects loop design mixes your amps dry or original signal, with the wet or “modified by effects” signal. I would like to patch them together.
