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. Class C amps are never used for audio circuits. They are commonly used in RF circuits. Class C amplifiers operate the output transistor in a state that results in tremendous distortion it would be totally unsuitable for audio reproduction. However, the RF circuits where Class C amps are used employ filtering so that the final signal is completely acceptable.

Leaving them open would be electrically the same as not having the second set coil present on the sub at all. I can recall a long time back where some company that made closed-loop servo subs had a demo box that allowed switching between 3 settings, an open sub, shorted coils, and active servo damping, and it was used to show the control exerted on the cone by the damping circuit, and the demo was to simply press on the sub cone and move it by hand.
The setting that shorted the coils showed that it would offer more mechanical resistance to movement due to the smaller amount of damping offered by the subs own electrical feedback. A sub moves from the electrical energy put across the coils, and in the same way that a motor and a generator appear to be generally the same, if you manually move a speaker cone electrical eneryg is created and would be measurable across the terminals.

Solid-state Bi-Wire Ideas Most solid-state power amplifiers are far cheaper than most tube power amplifiers. There, however, exceptions, as massive solid-state class-A power amplifiers cost a bundle. One idea that has danced in my mind for a long time now is that I would like to force a chip amplifier, such as the LM , into class-A mode More amazingly, DACs are getting better, almost monthly; and high-res digital music files can be bought and downloaded online.
This is certainly great news, but for us tube-loving folk our goal is to get hold of the analog output from our DACs as soon as we can, prior to the delicate signal traveling through any solid-state OpAmps Balanced Outputs One advantage of a balanced output signal is that as long as the receiving balanced amplifier delivers a high CMRR at its input, much of the balanced power-supply noise will be ignored.
If you are new to balanced audio, check out my post and post and post , all of which give good overviews. Indeed, I have posted so many balanced tube circuits that Google should be giving me a kickback for all of schematics that show up in their image search results. Here is one such example from post Electrostatic headphones, unlike dynamic headphones, require huge voltage swings and trivial current delivery—just what tubes do best, which explains a small paradox Well, I decided that it was time to actually build a tube circuit to mate with the Chromecast Audio puck.

About Us Select Page With free shipping and a risk free trial return policy, When we introduced The Bud amp at NAMM in , we knew we had something special on our hands, but we had no idea it would take off the way it did. Premier Guitar rated The Bud a solid 4. We had just released The Bud and they were anxious to try it out. He played a Bud amp on a gig and was blown away, so he wanted to come by for a tour. The FX loop sends the signal from the amp post-EQ and returns it pre-reveb.
Reviews Fareed Haque Amp sounds amazing, and works really well. Sounds great with classical and jazz guitars. Everyone should go pick up one or two. And you could pick up two because they are very small and light. I purchased The Bud last month and am happy to say it has surpassed my highest expectations. The Bud is an amazing sounding small amp with a big sound.
Barring specific brand recommendations I’d like to give some general advice on maximizing the bang for your buck when matching car audio speakers, subwoofers and car audio amplifiers. There are really two subtopics within the main topic. Matching amplifiers to full range speakers is different than matching amplifiers to subwoofers.
Can you hook up subwoofers to a factory radio – Posted on Saturday, November csn, – Posted on Sunday, November 06, – Posted on Wednesday, and what an RTA is and make sure he knows radio to use them because you hook need all three to set up a processor radio in a vehicle like this.
Some equipment, especially amps, have multiple OHMS ratings. But what does it all mean, and why is it all so important? OHMS are a way of measuring Resistance. Resistance is the measurement of an electrical device or circuits ability to flow electricity. Low resistance means the device is able to “pass” more electricity, high resistance means it “passes” less. Resistance is a Static measurement it does not change. Speakers do not have a resistance, as whilst the cone moves the effect of the magnets in the motor causes the resistance to change.
Impedence is also known as Speaker Load. OK so now you understand what OHMS are and how they related to the speakers impedence, how does that help? It helps you determine which speakers are going to be suitable for your equipment! As we know, LOW Impedence means more power passes from the amplifier to the speaker making it louder, and vice versa. Visit this article for the video version of this article.
But first lets familiarise ourselves with different audio configurations: Amplifiers which support Bridging allow you to “team up” two channels to increase the power.

In my case, I also have the added burden that two of my main contributors are or were speaker manufacturers, some of whose products you will see as References below. Other associates are distributors of speaker lines. Accordingly, I made the only decision I could: All the choices in this category are mine alone. What I say to those who question my objectivity is; please closely read the rest of the References first to see my consistency and sensitivities, before making judgements on the few choices you may be understandingly skeptical about.
Oct 31, · Almost any sub that you put in there will work best with an external amp, wasn’t hard to do the amp hook up, I used the signal from the factory amp to the sub and just stuck the amp in between, where to put it was the only problem and there is plenty of room in the seatback, you just need an amp with fans or to add some.
The Ariel My cabinet-making collaborator, Mike Spurlock, wanted a simple system for his beach cabin. As I filled in the details, I commented, “These particular drivers are really easy to use, since they’re quite flat on their own, sound pretty good, and only need a minimal crossover. The transmission-line ought to provide better bass and midrange than a closed box, and it also avoids the need for an expensive stand. That’ll be twice as efficient, so I can use my new B triode amp.
Let’s talk about this some more After all, I did need something to talk about for my next article. The Ariel made its debut in Vol. Maybe something a bit more significant was beginning to stir Design Principles Three key ideas emerged: Higher-than-average efficiency combined with natural and lifelike sound, spacious imaging, and a slightly warm tonal balance not a thin-sounding minimonitor balance, in other words.

What is the difference between a dual voice coil sub and a single voice coil sub? Dual Voice Coil Subwoofers. Dual voice coil subwoofers are becoming a popular choice among car audio enthusiasts who want more flexibility in wiring their sound systems. While typical subwoofers have a single voice coil, dual voice coil DVC subwoofers use two separate voice coils, each with it…s own connections, mounted on one cylinder, connected to a common cone..
The key difference between single and dual voice coil subwoofers is the multiple wiring options DVC subs offer:. A dual 4-ohm voice coil subwoofer with its coils wired in parallel presents a 2-ohm load to your amplifier. Since an amplifier produces more wattage at a lower impedance, the parallel connection ensures you’ll get the most output from your amp. In the same fashion, if you have a stereo amplifier and two DVC subs, wire both subs for 2-ohm impedance one per channel for maximum output.
Series wiring lets you configure multiple woofers to one amplifier at an acceptable impedance. Wire both coils in series for an 8-ohm impedance, and then wire two 8-ohm subs together in parallel for 4-ohm total impedance perfect for most 2-channel amps bridged to mono operation.
2 channel amp to 2 subs that are dual voice coil?
Back up camera system component listing Trigger wire based systems The easiest way to understand how a standard backup camera system is installed is by understanding the components. Most back up cameras and systems have similar components. This particular guide is designated for backup camera systems with trigger wires. A backup camera system can be broken down into five basic components See picture above. The monitor will come with a power harness that will attach to the single cable coming out of the monitor.
This particular monitor has several connections:
Diagram shows two DVC 2 Ohm subs with each subwoofer’s voice coils wired in series to form a 4 ohm speaker (2 + 2 = 4), then the two 4 ohm subs are wired .
You will want one that meets your specific needs for your specific vehicle. It needs to fit your vehicle, as well as your preferences. So take your time and select and item with care. First of all, you need to look at the dimensions and measurements of the powered subwoofer. Make sure the product you choose can fit in your trunk or under the seat. Take measurements to ensure that your car has enough space for the item you desire.
If you are choosing a subwoofer for your trunk, you should have enough space no matter what you drive. However, if you are choosing a subwoofer that will be placed under the seat, you need to make sure there is enough height. This is very important if you have a car with power front seats, as these seats often have components underneath.
You should also be on the lookout for how much power the sub you choose can handle. This will be listed in watts and will give you a good idea of how much power the subwoofer can handle. The key thing to consider, since these subwoofers are already paired with an amplifier, is how powerful you’d like your system to be. The more power, the louder the system will be. Most subwoofers have 4-Ohms, but there is a vast variety of products available so finding the right one for your needs should not be a problem.
