I spend a lot of time wearing headphones. A computer is my principal source of musical entertainment, and my Sennheiser HD s are my preferred output transducers. It’s been a while since my main computer was even connected to a speaker system. Headphones need about a thousandth as much power as loudspeakers to achieve similar sound pressure levels at the eardrums. This generally means a few milliwatts per side, at most, for normal listening. A few tens of milliwatts, for loud music or if you’re using unusually inefficient ‘phones – as with loudspeakers, manufacturers of high-end headphones may sacrifice efficiency for higher fidelity. You wouldn’t think even cheap music hardware would have much trouble delivering this little power. But, actually, even quite expensive home stereo gear frequently doesn’t drive headphones very well, especially at high volume. And if you’re pumping your tunes out of a mobile multi-faceted transformative device at sufficient volume to cut through the sound of the bus, surf or very upset policeman tied to a chair , you’re likely to be asking for rather more power, from an amp of rather lower capability.

In reality, a lot of these variables are mutually exclusive: If you want maximum power output, be prepared to pay more for the drivers and sacrifice some frequency response. Keep these things in mind as you read over the next sections. A Note on Speaker Selection Don’t skimp too much on the speakers: However you can have all of the above qualities without spending a fortune.
A word to the wise:
The hazards involved when running multiple amplifiers together can be potentially life-threatening, so when in doubt, don’t hesitate to call a local professional for assistance in setting up your multi-amp rig.
Just what is tone? What is a good tone and how do you achieve it? Which amps you should choose for your setup and how to get the tones you want. Check out part 1 and part 2. Amps People tend to prioritize guitars and a bunch of pedals and forget the importance of a good sounding amp. Choosing the right amp for your setup is crucial for getting the tones you want from your guitar and pedals.
I strongly suggest that you buy a guitar and amp before you spend all your savings on pedals. This will ensure the best fundament for your tones and playing. A tube amp consist of a pre-amp section that takes the small signal from your guitar and amplifies it enough to drive the power amp section. Most amps allow you to manipulate the pre-amp signal with a number of gain and EQ controls. The signal is then fed into the power amp, which gives the power to drive the speakers.
DC Thermal 12 Volt Ducted Heater – Direct Hook-Up – 50 Amps, 600 Watts – 10,020 BTU
About Amps Finding the right amp for your bedroom and smaller clubs, can be a challenge. During the last decade, the market has been flooded by affordable tube amps in all price ranges and while most of them will cover your basic needs, there are some distinct differences that will have an impact on your tone. The large tube stack phenomenon started in the late 60s, when bands moved to bigger stages and needed more volume and wattage.
Jan 08, · The only thing I left out was the remote turn on wire but in case that’s not common since to you: Split it in 2 and put one end to one amp and the other end to the other amp, or u can also daisy.
Wow is there a difference! I have read some other reviews who complain about the lack of I have read some other reviews who complain about the lack of power, this is a practice amp. You could probably play a smal bar and band practice for sure; anything larger you need to pay more than hundred for an amp. I have also heard a complaint about the lack of distortion, which was my main worry. It has plenty of distortion and gain; not sure what guitars the other reviewers are playing.
The best feature is the “MidShift Button”, it works on rhythym or lead channels and makes texturing your tone just a bit very easy. As someone who is still taking lessons and learning, I appreciate a good quality practice amp. It is nice to be able to hear clearly when I clunk a chord or accidentally catch another string. I didn’t have that clarity with the Randall or the Fender and the distortion is much better. I’m very glad that I traded my amps in on other equipment and left me with an opening to buy this gem.
VS realy great deal and great price it is a realy good little amp the distortion channel is realy loud but the clean channel not so much. Read complete review it is a realy good little amp the distortion channel is realy loud but the clean channel not so much.
Summary Do not assume you can put two rated cables together to extend your length. Length and wire size are tied together to give you minimal line loss. Two smaller wire sizes although rated at a specific amperage will not be big enough and you can see significant voltage loss. You do have the option to build your own cables. The important aspect is to use rated connectors and then match a length of wire that has appropriate wire size to minimize voltage losses.
The following information provides you with general information and links to specific cables that will provide you with what you need to get your appliances and tools connected.
Connecting two guitar amps together is a technique that many veteran guitar players use to expand their sound. This technique allows you the ability to use two different-sounding amplifiers to create a .
Most receivers have either preamp-in and preamp-out connections or tape monitor connections. In most cases, these are the best way to connect an equalizer to your stereo. Connecting to the tape monitor channels will require connection to only your receiver. Learn how to hook up an equalizer to the receiver instead. To run a signal from your stereo receiver to the equalizer and then to your amplifier, you will need 2 sets of RCA cable the same kind that is usually used to connect source components like turntables and CD players.
The length of the RCA cables should match the length of the distance between the receiver and the equalizer.
The answer ended up being a bit long, so I’m giving it its own page, rather than putting it in one of my serried ranks of letters columns. Something as beautiful as my original DIY UPS would, of course, be cheap at any price, but the thing itself didn’t cost me much. I had almost all of the bits sitting around already, and a local battery place gave me the slightly used fancy battery. This knowledge, of course, doesn’t help someone who’d like to build something like that for themselves.

Building a Stereo Tube Amp Ever wanted to build a highly dangerous, inefficient, yet awesomely retro piece of electronics? That’s pretty much what a tube amp is. Vacuum tubes are old electronic components that act like transistors, controlling a lot of current with a little current. You usually hear about tubes being used in guitar amplifiers, because they distort in a way that suits guitar playing. However, tubes can also be used to amplify a stereo signal from another audio source such as a CD or MP3 player.
Tube amps, unfortunately, aren’t the most practical things in the world; they consume a great deal of power, get very hot, and are big. That being said, they look damn cool, and some people seem to think they sound pretty nice, too. You can learn a lot about electricity and electronics from a project such as this. Going through the process of purchasing parts, planning, and executing is a useful experience for any maker.
August 29, at 1: Undo Auger01 Your contractor is pretty much correct with his reccomendations. A kw unit is marginal for central AC. It doesnt leave much room for anything else. With that being said, I can run my four ton AC with my 12kw Winco generator without problem.
Sep 10, · The one thing I will say though, the sound may be degraded or influenced by whichever amp the source is played into first so it would be better to wire the source into the first amp / speaker combo, then using the same source / interconnects, wire it into the second.
It is remarkably compact and portable for a live sound system with this much capability. And thanks to leading Yamaha digital technology, the EMX CF also includes a number of innovations that make it easier than ever to achieve top-class sound in just about any venue. An impressive power output of watts per channel means it can handle fairly large audiences, indoors or out. Versatile input configuration adapts to varied source requirements The EMX CF has a total of 16 input channels-eight for monaural microphone or line input plus four stereo pairs.
The stereo channel pairs can function either as monaural microphone inputs or stereo line inputs. This system gives you extra microphone inputs if your sources are mostly microphones, or if you need to handle more stereo sources, the EMX CF will comfortably handle four pairs in addition to eight mono mic or line inputs. Advanced channel EQ 3-band EQ is available on all input channels, but extra versatility is provided on the eight mono channels with mid-frequency sweep controls.
The mid EQ center frequency can be continuously swept from Hz through 5 kHz so you can precisely pinpoint frequencies in the critical midrange. But it does feature a range of inputs and outputs that allow it to be expanded with external gear or integrated into larger systems. Insert patch points on the mono input channels, for example, let you add outboard signal processing to individual input channels. Stereo out, stereo sub-out, and record outputs are also provided. These unique one-knob compressors are surprisingly simple to use.
One-Wire Alternators: Are They Better Or Just Easier To Hook up?
Electric fluid “Charge-stuff” Why are Amperes confusing? Suppose that we had no name for “water,” and yet our teachers wanted us to learn all about the mysterious flow inside metal plumbing pipes? Suppose we were required to understand “gallons-per-second,” but we had to do this without knowing anything about water, or about gallons? If we’d never learned the word “gallon”, and if we had no idea that water even existed, how could we hope to understand “flow?
We might even decide that “current” was an abstract concept. Or we might decide that invisible wetness was moving along through the pipes.

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.
can a central AC run off a portable generator?
Here is what I recommend. This measure assumes a reasonable ambient air temperature typically c , that the heat sinks are black anodized, have free air circulation not using a fan and given plenty of breathing room-usually 8 inches on all sides and don’t sit directly on the floor , and that the fins of the heat sink are oriented vertically. Be aware, though, that different vendors will have different assumptions when measuring and quoting the thermal dissipation of their heat sinks – sometimes you cannot reliably trust the figures.
To get an idea of what you need, follow these steps:
Nov 07, · Best Answer: Assuming both amps are identical and both subs are identical, just connect one to each amp. The amps can’t be connected together unless they are ‘strappable’. There are very few strappable amps on the market today. The RCA wires need to go to each amp by use of a ‘y’ : Resolved.
The Logitech Z has a clear sound with rich bass. It has headphone and line connections. On the back of the subwoofer, there is a knob that lets you control the bass volume. The Logitech Z has many positive reviews and ratings. Some consumers recommend using the RCA inputs as the 3. It costs a little bit more, though. You can connect your turntable to the RCA inputs. You can play music from your computer.
This set of speakers work as an audio interface. This is very helpful if your turntable does not have USB connection. These speakers have a headphone jack and a bass boost switch. They have a power of 10W per channel, so they may not be to loud for a large room. There are some differences between the AV 30 and AV
