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. An explanation of these formulas can be found in the article The Dreaded Ohms Law. You can wire two amplifiers, or even multiple amps, … When building a home audio system on a budget, you may need to connect multiple speakers to one amplifier. This distributed speaker system SPL calculator takes the guess work out of which speaker tap to use. If you connect the speakers in series, you're adding the speaker impedances together. In parallel however, the total impedance decreases when adding more speakers to the circuit. You cannot connect powered or active speakers to a receiver's normal speaker terminals because it WILL damage the speakers. After some research i found out that you can wire multiple speakers to a single channel. Of course you can connect multiple speakers to both the left and right amp of a stereo – you just need to follow the principles twice, once for each amp. We need six amplifier channels to power the five speakers in Zone 1. We don’t really turn the outside speakers up super high. To understand what all this means, we need to get technical and use some formulas. If you need to get the maximum power from the speakers, then… Read more ». Thread starter audaciousgoat; Start date Nov 12, 2014; Tags Amplifier bookshelf speakers Converting Speakers; Sidebar Sidebar. That depends on how loud you need it to be. No one could figure it out which surprised me but you did and I appreciate it! But congratulations to you for giving it a go and making it work – well done! Most amplifiers can cope with a load of two speakers. They are normally good for lower powered amplifiers, and the resistor can get hot at high volume levels. Please note, speaker selector switches are designed for multi-room installs in a home or small low power installs (like an office or cafe). The answer is: it depends on the type of charger. This would work fine if you’re only using 5.1 channels, the other two channels can… Read more », Thank you for this excellent forum. At this point, we hope it has a limit/protection circuit and has turned itself off, or at the very least the 5 amp protection fuse inside has blown. Of course you can connect multiple speakers to both the left and right amp of a stereo - you just need to follow the principles twice , once for each amp. 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. If you don't like formulas then you definitely won't like the formula for calculating voltage ratios expressed in decibels. For best results, go for heavy gauge cables, and also ensure that the cable length between the amplifier and the speaker is not too long. Learn more about hooking up tow amps with one RCA jack. Each amplifier is able to handle only a certain number of watts at a particular ohm load, which is the resistance the amplifier gets from the speakers. Then do the same for the - terminals. That means that they work by maintaining the safe operating load of an amplifier while circulating maximum power in the system. Any concerns? By adding an extra speaker to the output of an amplifier, you are adding to the load of the amplifier. Use AmpMe to Connect Multiple Bluetooth Speakers I am often asked “How do I connect multiple speakers to my amplifier?” Before I answer, let’s define what we mean by the word “amplifier”. Also if the speakers each have a different impedance, then there will be different power levels available to each speaker.
