Your Amplifier’s Gain Control Is Not A Volume Control


When a manufacturer decides to develop an amplifier, they need to decide how many channels it will have, how much power it will produce, what additional features it will include and what source units it will work with. Because modern source units have maximum preamp output voltages that range from 1. This is a reasonable amount of signal gain, but leaves us open to two significant problems.

What if we want to use this amplifier with a source unit that can only produce 1. In fact, we only get On the flip side, if we have a source unit that can put out 4 volts of signal, then the amp would attempt to make watts with our fixed gain setting. Since the power supply of the amp was only designed to provide enough voltage to produce watts, the signal would be severely clipped and distorted, and there is a great chance that the amplifier and your speakers might be damaged.

For a single amplifier to work with multiple sources, amplifier manufacturers have to make the input signal level adjustable. We call this the gain or sensitivity control. There is a secondary reason for adjustability: Not every speaker has the same sensitivity. This means that sometimes you have more power than you need.

For them to appear to be of equal loudness at the listening position, we only need half the power to the rear speakers. We turn down the sensitivity of the rear channels of an amplifier to balance these out.

Your installer may use one of many different processes to adjust the gain controls of your amplifier. We want the gain controls to be as low as possible, but still allow you to get full power from the amplifier. Why do we want the gain low? That is, perhaps, the fundamental key to this article.

We want the amplifier to accept an input signal with as much voltage as possible for it to produce full power. Having more voltage on your interconnect cables helps drown out noise. Less amplifier sensitivity lower gain setting also helps to reduce noise.

When the amplifier gains are set properly, you get full power from your amp without unnecessary hiss or background noise. There are four common methods for adjusting gain controls: by ear, with a small amplified speaker, with an oscilloscope or with a distortion detection device.

Setting by ear with music is very difficult and can lead to inconsistent settings. Using a small amplified speaker is similar to that process — there is a test tone, but the small speaker allows your installer to check the preamp signal from the source unit, and in and out of any signal processors. Oscilloscopes work for any frequency, so they are very flexible. Your installer can see exactly when the amp has reached its peak voltage. All you have to do is plug the device in and turn it up until the red Distortion LED comes on.

Bam — done! A word of warning on these devices, though: They are very accurate and can detect distortions other than signal clipping. Many product design problems have been found when attempting to set gains with these. If the sensitivity controls on your amplifiers are set properly, you should be able to get your amplifiers to distort a little bit with the source unit at full volume. We want to have a little extra sensitivity in case we are playing a song that is recorded quietly.

It needs a good 5 extra dB of gain to get rocking. In fact, the original release from Warner Brothers Records had several songs where the loudest part of the song was below -5 dB. Likewise, if you hear a significant amount of hiss at low volume levels, then you likely need an adjustment. Gain controls exist to ensure that your system is always working the best it can. Please leave them alone, or ask your installer about how they are set.

Testimonials div. I needed a tough installation done on my 4Runner and Ben did a fantastic job. Couldn't be happier with the result or the service. Highly recommend! He did a phenomenal job with my automatic starter, it only took a day and I upgraded to start the car from anywhere with my cell phone. These guys are friendly, knowledgeable, and informed when it comes to what you want in moble electronics. I would recommend to anybody looking for car accessories.

Ben is a savvy engineer, knows his business, remote starts custom audio even designs his own high-end subwoofers.

3 Ohm Subwoofer Amplifier

This is the cheapest Watt amplifier circuit you can make,I think. Enough for you to get rocked? TIP and are complementary Darlington pair transistors which can handle 5 A current and V ,famous for their ruggedness. This circuit is designed so rugged that this can be assembled even on a perf board or even by pin to pin soldering. You must try this circuit. Its working great! The preamplifier section of this circuit is based around Q4 and Q5 which forms a differential amplifier.

While your voice coils are either going to be wired in series or parallel, some subs have only one voice coil while others are dual voice coil and each voice coil will be rated at either a 2 ohm or 4 ohm load, so there are quite a few different wiring configurations possible, the main thing to remember is that your amp must be capable of running the ohm configuration that it is presented to it. Many amps for instance are not 1 ohm stable and can overheat if the subs are wired incorrectly.

Where should you place it? How's best to connect it?

An audio power amplifier or power amp is an electronic amplifier that amplifies low-power electronic audio signals such as the signal from radio receiver or electric guitar pickup to a level that is high enough for driving loudspeakers or headphones. Audio power amplifiers are found in all manner of sound systems including sound reinforcement , public address and home audio systems and musical instrument amplifiers like guitar amplifiers. It is the final electronic stage in a typical audio playback chain before the signal is sent to the loudspeakers. The preceding stages in such a chain are low power audio amplifiers which perform tasks like pre-amplification of the signal this is particularly associated with record turntable signals, microphone signals and electric instrument signals from pickups, such as the electric guitar and electric bass , equalization e. The inputs can also be any number of audio sources like record players , CD players , digital audio players and cassette players. Most audio power amplifiers require these low-level inputs, which are line level. While the input signal to an audio power amplifier, such as the signal from an electric guitar, may measure only a few hundred microwatts , its output may be a few watts for small consumer electronics devices, such as clock radios , tens or hundreds of watts for a home stereo system , several thousand watts for a nightclub 's sound system or tens of thousands of watts for a large rock concert sound reinforcement system.

More balance, more detail, no noise, neutral sonic coloration. The circuit will run from 6 to 15 vdc and give about 20 dB of gain. The unit is composed of heavy gauge steel with a wood front panel, a variety of which are available as options.
