Vehicle Amplifier Fundamentals

Mon, 19 Sep 2011 16:47:26 -0500

Most subwoofer speakers existing four ohms of resistance. If wired the right way, you will lower the load impedance that the amplifier sees. You will reduced the impedance down to two ohms, which is where by most mono channel amplifiers are develop to conduct the most effective.

Two Channel Amplifiers- A two channel amplifier is an amplifier that can run a person correct, and one particular left hand channel. It is fundamentally two mono channel amplifiers in a one box. Considering that two channel amplifiers are usually stable when presented with four ohms of impedance, they are best suited to drive both one particular 4 ohm "single voice coil" subwoofer, or two four ohm "dual voice coil" subwoofers. To operate these setups, you have to "bridge" the channels coming from the amplifier. Not all two channel amplifiers are bridgeable, so be confident that your two channel amp is bridgeable prior to you acquire it.

What is "bridging"? Lets say that you are wanting to buy a two channel amplifier that is rated at 500 watts RMS. You need to know that the amplifier does not offer 500 watts of strength from every channel. As a substitute, every channel alone will offer all over 200-250 watts. In buy to get the marketed 500 watts, you have to combine the two channels into one particular channel. This is known as "bridging" the channels.

*Be aware- Be watchful when "bridging" the connections simply because if it not completed effectively, then you will demolish your amplifier.

Many Channel Amplifiers- Multiple channel amplifiers let you to hook up various speakers (commonly entrance two and rear two) when nonetheless making it possible for you to control your equilibrium and fading solutions. When buying for numerous channel amplifiers, you will obtain that whilst most are nevertheless rated in the two-4 ohm impedance assortment, some are rated all over twenty-forty ohms of impedance. The only time you would ever before will need an amplifier at this superior of an impedance rating is if you had been to wire several speakers in a "series". Many channel amplifiers can be used to run subwoofers, but you have to make positive that the amplifier's channels are bridgeable due to the fact most of the time, every single channel of a a number of channel amplifier does not give out virtually enough watts.

What is "series" wiring? As an alternative of wiring every speaker individually to every single channel of an amplifier, from time to time it is recommended that you wire two or far more speakers jointly. After the speakers are wired in concert, you want to wire the total unit of speakers to a person channel of the amplifier. To wire the speakers collectively, you merely operate a speaker wire from the positive terminal of 1 speaker to the adverse terminal of an additional speaker. The moment this is carried out, you operate speaker wires from the channels of your amp to your remaining positive and detrimental terminals on your speakers.

*Observe- You have to keep monitor of load impedance when you are wiring speakers in "series". When wiring in a series, you simply just add up the number of ohms of each speaker. Make certain your amp is rated to operate at that superior of an impedance.

Car Stereo Amplifier Installation Basics

Thu, 01 May 2008 00:00:00 -0500

A car stereo amplifier is a necessity if you take your car audio seriously. A car stereo amplifier is what helps determine the type of audio output your stereo will produce. If you have never experienced what a car amplifier can do, you will be blown away at the quality of sound that can be achieved. In fact, once you hear your favorite music played with the power of an amp, you will be instantly hooked.

When you decide to purchase a car amplifier, one of your first decisions will be where to place it in your vehicle. You have several options but keep in mind an area where the amplifier will have the best air circulation. Common areas to install the amplifier include the trunk or under a seat. Also remember that the amplifier needs to be grounded so a metal surface to attach it to is key.

Most people will have professionals install their car amps. If you are a do-it-yourselfer, the next step is deciding how to connect the amplifier to your car stereo. RCA cables are the common cable type to use and they are used to connect the low level radio output to the low level input of the amp. There are other cable set-ups to use and some precautions to take before hooking up cables. These precautions should be laid out fairly well in the user's manual.

There are a few things to keep in mind when installing a car amplifier:

1. The amplifier should be installed on top of metal as a ground conductor.
2. Ground cables should be connected before the RCA cables.
3. Avoid installing power cables next to RCA cables to help avoid extra noise.

Again, the user manual should go over these elements in depth. Number one is very important, since newer model cars are made mainly of fiberglass, it may be difficult finding a solid piece of metal to attach the amplifier to.

When it comes to such technical issues as installing a car amplifier, you may be better off spending the extra money having one professionally installed. You can save yourself a lot of time and frustration. However, if you are adamant about doing it yourself, research online as well as reading the user's manual thoroughly to be safe and avoid any damage.

Guitar Amp

Wed, 12 Oct 2011 07:47:56 -0500

Is it better gettinga combo amplifier or a head-and-cabinet

This one is actually pretty simple, as it really depends on just how big is the venue you want to participate in. For club dates and also small stageas, conteporary combos are well-equipped to garantee massive power to convey strong sonics that will be heard all the way in the back. If your goal is to have enough acoustic firepower to fill a giant auditorium or also an outdorrarena, there is no question that you'll need a powerful amp with at least a 4 x 12 cabinet, as the Marshall DSL100 with a 1960A cabinet. In addition to that, some players still like more a smaller amplifier - such as a Vox AC30 Classic Custom - for its characteristic acoustic tone, and then simply mic the amplifier and rely onto the PA set .

Which is better: solid-state or tube?

Usually the common thinking is that solid-statesolid state circuitry could may generate more elevate cleanpower at a much affordable price, while the low level of vacuum tube manufacturers nowadays tends to make tube-based amplifiers much more expensive in a comparably powered amp. This factto some interesting hybrids that have the tone produced by a tube-driven, while the power amp is solid-state. Moreover, the mostmajority of pro artists will almost always lean towards a tube amplifier, though the philosophy is changing as manufacturers came up amazing new amplifiers that are designed on cutting edge design, as the Fender Cyb Twin SE Amplifier.

If you are buying an amplifier pay particular attention to how much amplification degree you want, and which style of music you want.

Guitar Amplifiers - Choosing the Right Type

Sun, 04 May 2008 00:00:00 -0500

A musician who takes their craft seriously will invest in the best music equipment possible. This process is no different for the guitarist in need of a good quality guitar amplifier. If you are new to the world of guitar amplifiers, don't let the various brands and models confuse you. The basics below should help you on your way to making the right choice.

There are four basic options when choosing a guitar amplifier. Amplifiers are available in tube, digital, hybrid, and solid-state. Tube amplifiers were the first amplifiers in use. While this remains the older model amp, many guitarists prefer it as it produces a more natural sound than the other models. The output is also greater and is much louder in comparison to the other models. However, since tube amplifiers are built with glass tubes, transporting them needs to be done with care to avoid breaking the tubes.

Digital amplifiers are one of the more expensive types of amps due to their ability to mimic various ranges of amplifier sounds. You can find lower-end versions of the digital amplifier, however you get what you pay for, and the sound quality will be lower. Many guitarists enjoy digital amplifiers as they are able to experiment more with different styles and sounds.

The hybrid guitar amplifiers do exactly as the name implies. They are a combination of the tube amplifier and solid-state amps. Unlike the sound quality you can achieve with a regular tube amplifier, the more natural sound will be lacking. The hybrid amplifier is a good option for those who want a decent amp but are on a budget.

Solid state amplifiers are simply made with transitors rather than the glass tubes. This may be a preference for those who tote around their amplifiers often, as their isn't as much worry about breaking the tubes. Sound quality on these amplifiers are decent but still not as favored as the original tube amplifiers.

Before choosing your next guitar amplifier, you may consider asking to try out the various models before you buy. Don't hesitate to ask to try before you buy. Most music stores are more than happy to cooperate in order to help in the buying process.

Amplitude Radio Transmitter: What does it all mean and how does it work?

Tue, 10 Jul 2007 00:00:00 -0500

The amplitude radio transmitter using high frequency power level of carrier has the following constituent stages namely master oscillator, buffer amplifier or isolating amplifier, harmonic generators, class C power amplifiers, modulated amplifier and the modulating amplifier. All high frequency power level of carrier requires all there stages.
The master oscillator generates oscillations of desired frequency with high constancy of frequency. The generated frequency is required to remain constant within close limits in spite of variations in the supply voltage, ambient temperature and temperature of components of load. Further frequency variations with time and with age of the transistor should be avoided.
If the master oscillator directly drives a harmonic generator or class C power amplifier which draw input current then power is drawn from the master oscillator. This results in loading of master oscillator which in turn causes variation of effective resistance of the tank circuit of the oscillator and hence results in frequency variation. Accordingly a buffer amplifier or isolating amplifier is placed between the master oscillator and the harmonic generators. This buffer amplifier does not draw any input current and hence causes no loading of the master oscillator. Changes in carrier frequency due to variations in loading are thus avoided.
Usually the master oscillators generate voltage at a frequency which is a sub multiple of the carrier frequency that is the frequency of the radiated power. Basically these harmonic generators are class C tuned amplifiers in which the output radio frequency voltage is first distorted through class C operation and then the tuned circuit in the output circuit of amplifier selects the desired harmonic frequency.
The radio frequency voltage generated by the master oscillator has usually very small power of the order of few watts. The power level is required to be raised to the final high value in a chain of class C amplifier having high output circuit efficiency of the order of seventy percent.
The modulated amplifier is a class C amplifier usually of the push pull type and is modulated by audio modulating voltage from modulating amplifier. High efficiency series plate modulation is most popularly used in high power radio broadcast and radio telephone transmitters. Grid bias modulation and suppressor grid modulation are used particularly for modulation at low power levels.
The modulating amplifier is usually a class B push pull amplifier and feeds audio power into the modulating amplifier in the plate circuit, the control grid circuit or the suppressor grid circuit depending upon the method of modulation used. Class B operation is generally used because of high plate circuit efficiency. While the Class A modulating amplifier are also sometimes used particularly in low power transmitters.

How To Set Up a Home Recording Studio in 7 Days Flat - Day 4

Wed, 06 Jan 2010 16:10:26 -0600

Having your own home recording studio is one of the biggest advantages you can provide for yourself as a musician. In this 7 part report on setting up your own home recording studio, we are discussing some of the technical specifications and advantages to necessary recording equipment. As we arrive at Day 4, we are past the halfway point and it is time to discuss the various amplifier options available and how to choose the right one for your home recording studio.

When you are gathering the necessary equipment for your home recording studio, the amplifier is a component that can greatly improve the quality of your recordings. Depending upon your budget and other equipment, you may be able to bypass the need for an external amplifier unit and use software options instead.

If you choose to use a physical amplifier unit instead of software, either out of personal preference or necessity, there are a few options you need to consider.

Does the amplifier you are considering have enough hook ups to connect all of the equipment you want to run? There is nothing worse than assembling your whole band for a recording session and discovering your amplifier is two inputs short.

Does the amplifier have phantom power jacks? If you are running microphones that require a phantom power source, your amplifier needs to fit the bill.

Does the amplifier have RCA output jacks? RCA output jacks are industry standard on many amplifiers but it is always best to check before you buy. If you don't have RCA outputs, you may encounter real difficulty when you try to hook your amplifier up to your recording system. Amplifiers lacking the RCA outputs may still produce a great sound but we are discussing how to create a recording studio. If you can't connect your amp to your recording system, it defeats the purpose.

Cost is always a factor when purchasing equipment for your home recording studio. There are many cheap amplifier options on the market today but, unfortunately, a lot of them sound cheap too. Try the system before you buy it and, as always, purchase the best quality for the money you can afford to spend.

Size is also a consideration. In most home recording studio settings, space is limited. Amplifiers come in a variety of sizes and, in your eagerness to buy the best amplifier money can buy, you might find yourself with a goliath sized monster that won't fit through your front door.

As a final note, you can save a lot of money on your amplifier purchase by shopping around a bit. Check online electronic sales and catalogs for good deals. Even second hand equipment is fine if you check it before you buy it. Hit up the local pawn shop or the classifieds and you might find yourself taking home a Mark Levinson amplifier for $20.

Check back soon for Day 5 when we will discuss software options for home recording studios.

Karaoke Accessories: Should I buy a karaoke Amplifer?

Fri, 14 May 2010 18:46:20 -0500

One of the most popular up and coming past times is singing karaoke, either in bars and restaurants or at home with friends and family. Deciding whether or not to get a karaoke amplifier depends on your commitment to karaoke, be it your business or throwing huge gatherings.

The main reason people buy a karaoke amplifier is to increase the volume of both the music and the singer. This can benefit your business if you own a bar, restaurant or party planning company because it allows more people to attend the events as the volume of the karaoke can overpower a crowd and fill a big space compared to a small karaoke all-in-one system. This same benefit applies to people that like to throw large parties for friends and family. A karaoke amplifier can suit a big gathering like a family reunion that may be outside, as the sound from the karaoke amplifier will carry and everyone there will be able to hear and participate.

To choose how many watts your karaoke amplifier should be you should consider both the number of people you expect at your venues and also the size. You should purchase an amplifier that will cover the largest of both of these requirements because you can always turn your amplifier down for a small venue but to go bigger you will need to buy another amplifier and this will cost you more in the long run. You may also want to look for features in a new karaoke amplifier like the number of microphones you can use with it. A lot of people like to sing karaoke with their friends so the more microphone inputs the better and if you run a business this can give you an advantage over your competition. Some amplifiers even come with a remote control so you can have your amplifier out of sight but still control things like volume in case tweaking is required between performers.

As a business, a karaoke amplifier is a great investment and as an avid party host it adds to the fun and quality of the parties you throw.

Servo amplifiers are a kind of circuit board that are utilized in many peculiar machines to serve them to work the right way. They aid to repair minor problems that is preserving the information from being transmitted to contrasting locations. The PI Piezo E-481 High Voltage servo amplifier is a crucial product that utilizes high force actuators to transmit of 2000 watts.

This is thought to be one of the more compelling and energy effective amplifier that is on the market now. It is built with a bipolar driver circuit that sends off 2,000 watts of power and is developed with an output voltage of 1100V. It likewise uses a source current to 2000 mA and a bandwidth of 5 kHz that presents it the ability to have exceedingly high slew rates despite the big loads of capacitive piezoelectric.

The Piezo amplifier is able to be utilized in both noninverting and inverting modes with a DC gain of at least +/-100. This unique design grants it the ability to use two piezo actuators to be set into the push/pull mode. This permits it to utilize the maximum in force and stroke that is necessary to work the right way.

The E-481 servo amplifier was made to be used for reactive or capacitive loads through large piezoelectric stacks. It operates to recover in a way that permits simply the active power to be utilized by the actuators. When the actuators are being discharged the energy not being used will be delivered and recycled in order to provide for the amplifier.

Car Amplifiers That Will Go Great With Your Vehicle

Mon, 13 Dec 2010 11:50:10 -0600

Do you like the sound of a cars sound system? Well, did you know that the sound in a cars stereo system depends a lot on the car's amplifier? Yes this is true, without a good car amp your sound system will just sound like junk. However, with the perfect car amplifier your music will sound like if you were listening to it live. If you want to get a really good sound coming from your car speakers then you must have a good amplifier. Just like any other product a car amplifier comes in many different brands, styles, and colors. All of these factors are things that you must consider because they will make the a significant impact on the price of an amp.
The first thing that people may look for is the color of the amplifier. The truth is that most of the time the car amp will be hidden so the color will not matter because no one will be able to see it. However, sometimes you might want to customize your car so that the car amp is visible. This way you will also be able to brag to your friends about the kind of amplifier you have and you'll be able to show them. If you are planning on leaving your amp in an open area then one thing to consider is the color of the amp. Most people like the neutral colors such as black or white. The great thing about neutral colors is the fact that you can match an amplifier to just about any type of car interior. Some people however, like to be a bit pickier about the colors so they go for more exotic looks. If your car interior is red then you can get a red amplifier to compensate. If you have a blue interior then you can also look for a blue car amplifier. If you are more in to looks then choosing a good color to compensate your car is well worth it.
Besides the color, another thing to look out for is the brand and style of the car amplifier. Usually, people will stick to the basic amp with 2 channels. This will produce a pretty good sound depending on the brand of the unit. However, others like to go all out and buy an amp with 4 to 6 channels. Usually this is good if you want to connect a lot of gadgets to your car amp. This method however, is the most expensive method and should only be consider if you plan on getting the most of your car amplifier.
The last thing to take in to mind and perhaps the most important is the price of the amp. These amplifiers can range anything from $50 to $300. There are some cheaper ones that can actually produce pretty good quality sound. So unless you are planning on connecting a lot of gadgets to your car amp then an inexpensive car amp will do the job just fine. Usually the best place to get these amps is at an online store. The reason for this is because they tend to have more selection and their prices are also better.

Guitar Amplifier Handbook - Understanding Tube Amplifiers and Getting Great Sounds (Softcover)

There's a huge amount of hype and mythology surrounding tube amplifiers in the guitar world. For years, experts have argued over the tiny details of exactly how they do what they do, and how their various components interact. What's undeniable is that, far more than being just a "loudness booster," the unique combination of tubes, capacitors, resistors, and transformers in these amps can contribute enormously to the quality of sound derived from any electric guitar. In this thorough and authoritative book, Dave Hunter cuts through the marketing hyperbole, and the blind faith, and supplies all the information you need to choose the right amp, and get the best from it. The book also features exclusively conducted, in-depth interviews with leading figures in the tube amp-building world - including Ken Fischer, Mark Sampson, and Michael Zaite - and even provides full instructions on how to construct your own high-quality tube guitar amp from scratch.
