August 17, 9: This is all fine but you are still limited with Bluetooth which is why no one really makes large Bluetooth systems but simple portable devices. As stated before bandwidth with Bluetooth is limited in he first place so you will not get the sound you would over a wireless 5ghz signal and there is still the range of Bluetooth which is very limited. Although it has improved in distance it is still not ideal. If I am going to want to run a larger system, I would definitely want the quality and Bluetooth will not give you that. Stick with either hardwiring your speakers with a docking station or jack or go wireless. If you are going for portability and small footprint and just want to listen to music without true fidelity but just have music then Bluetooth is the answer.
Class AB amps combine the good points of class A and B amps. They have the improved efficiency of class B amps and distortion performance that is a lot closer to that of a class A amp. With such amplifiers, distortion is worst when the signal is low, and generally lowest when the signal is just reaching the point of clipping. Class AB amps like class B use pairs of transistors, both of them being biased slightly ON so that the crossover distortion associated with Class B amps is largely eliminated.
Can you give me information on the Bluetooth Speaker please, it would help a lot as there are some Bluetooth speakers that you can play music out of multiple speakers at the same time without an app.
Speaker Connections for proper impedance match A note about amplifiers: You should always use the recommended load for your amplifier. However, if you must use a load other than the recommended load, here is a short guide. Most solid-state amplifiers would rather look at an open circuit no speaker at all than a load. Therefore, you can usually use a load that is higher than the recommended load.
Do not use a lower impedance load, as this could cause serious damage to your SS amp. On the other hand, most tube amplifiers need a load to avoid transformer or tube socket damage. If a mismatch can not be avoided on a tube amp, it is better to go towards a lower impedance rather than too high of a speaker impedance. This may stress the tubes some, but, tubes are cheaper than transformers. As the graphic shows, you connect the positive wire to speaker A"s positive terminal, connect a wire from speaker A"s negative terminal to speaker B"s positive wire, and then connect the negative wire to the negative terminal of speaker B.
You could continue this string for as many speakers that you have available, however, it may not be very practical.
It shows on the picture by the two AC outputs 7 and 8. I cannot find a download for the manual so I cannot confirm that both of these AC outputs are milliamps but this is what it looks like from the data on their website. Will this damage the unit? The amp comes with FX loop but currently my new setup is running everything upfront.
Started in by the Dark Tangent, DEFCON is the world"s longest running and largest underground hacking conference. Hackers, corporate IT professionals, and three letter government agencies all converge on Las Vegas every summer to absorb cutting edge hacking research from the most brilliant minds in the world and test their skills in contests of hacking might.
Do you need really huge speakers, and are they worth it? Yes they are…at all costs. The bigger the better! Monstrous, gigantic speakers sitting three feet away from your face and pumping out dB of ear-bleeding sound is exactly what you need! Just ask your spouse or the person sitting next to you. They ran out of the room screaming? The truth is, I once downsized my speakers when I went from a larger room to a new home where my theater needed to shrink.
If you want to understand anything about room acoustics, remember this: Loudspeakers always interact with the room in which they are placed. That means that if you place really large speakers in a small room, the room is going to have an effect on the sound produced. So how do you size up the speakers to the room? Well, you start with the room. Understanding your room is a big deal. The next things to look at are the dimensions and the listening position.
That is, in the one amplifier box, there are two different amplifiers. For the purposes of this article, we are talking about connecting multiple speakers to a single amplifier only, that is, either the left or the right, or any single amplifier. 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. Multiple Speakers on One Amplifier By adding an extra speaker to the output of an amplifier, you are adding to the load of the amplifier.
That is, two speakers is double the load of one speaker.

Key switches[ edit ] In the first electronic keyboards in the early s, the key switches were individual switches inserted into holes in metal frames. The most popular switch types were reed switches contacts enclosed in a vacuum in a glass capsule, affected by a magnet mounted on the switch plunger. This became more acceptable, however, for use in computer terminals at the time, which began to see increasingly shorter model lifespans as they advanced.
As the key was depressed, the capacitance between the plunger pad and the patterns on the PCB below changed, which was detected by integrated circuits IC. These keyboards were claimed to have the same reliability as the other"solid-state switch" keyboards such as inductive and Hall-effect, but competitive with direct-contact keyboards. Meanwhile, IBM made their own keyboards, using their own patented technology: Keys on older IBM keyboards  were made with a"buckling spring" mechanism, in which a coil spring under the key buckles under pressure from the user"s finger, triggering a hammer that presses two plastic sheets membranes with conductive traces together, completing a circuit.
This produces a clicking sound and gives physical feedback for the typist, indicating that the key has been depressed. Over time, less key travel was accepted in the market, finally landing on 0. Coincident with this, Key Tronic was the first company to introduce a keyboard that was only about one inch thick. And now keyboards measure only about a half-inch thick. Keytops are an important element of keyboards.

By hooking your laptop up to your TV, you can turn it into a media center, streaming your favorite Netflix and Hulu content, as well as playing YouTube videos and any media stored on your laptop. You can play games on the big screen, or edit a document without straining your eyes. Follow this guide to get your laptop hooked up to your TV. Steps Connection Basics 1 Determine which video output port s your laptop has. There are several possible types; your laptop may have more than 1.
One more thing, has anyone measured the output of the v ac to dc power adapter or the size of the power plug that connects to the echo? I am going to try to power my Echo with an 18v cordless drill battery and need to know how much to step down the battery"s volts/amps.

Can I connect multiple Bluetooth speakers to a device playing music
Before trying to hook up your player, make sure it is plugged in and turns on when you press the"power" button. Usually a small light or welcome message appears when the DVD player is working correctly. There are at three common ways to connect a DVD player, and each needs a different cable to work. Your DVD player should come with all of the appropriate cords, but you need to check which connections your TV accepts as well.
The three most common are.

Originally posted by Xevion: Let"s say the amp is swinging 8 volts RMS into an eight ohm load. Obviously the amp output is 8 watts, assuming no phase issues get in the way. Now let"s take the simplest case, 2x2. You start with four, eight-ohm speakers and you end up with an eight ohm load. We still have 8 watts power out of the amp, but where is it going?
Obviously, half an amp goes into each branch. Current in parallel branches of a circuit is divided inversely proportionally to the impedance in each branch. In each branch each speaker is dropping four volts. With loads in series, each load drops voltage proportionally to its voltage. Therefore each speaker is dissipating two watts.
