Impedance and Power: Two key factors to consider when selecting amplifiers for your speakers

If you are designing a sound system, then you need to try your best to select speakers and Audio Amplifier that work well together. Choosing the wrong amplifier for the speakers can result in poor sound quality and may even cause damage to your equipment. Impedance and Power are the two basic factors you need to take into account when trying to find a Stereo Power Amp that is compatible with your speakers. Both of these factors are closely interrelated.

Impedance is measured in ohms and implies to the opposition a circuit presents to electrical current. Your speaker shall basically “impede” the flow of electricity being created by the amplifier. You firstly need to determine the nominal impedance of your speaker or speakers. Such details can be found on the technical specifications provided by the manufacturer. The power rating of the speaker can also be found in the technical specifications. Power refers to the rate that energy is transferred, and is measured in watts. It is important to understand that more power does necessarily mean louder. The loudness would ultimately be determined by the sensitivity of the speaker, which tends to vary. Some speakers will provide more sound than others when supplied the same power level from the amplifier.Selecting an amplifier that can supply too much power makes it possible to exceed the limitations of the speaker, however, if you start to hear that speaker distortion, it is better to turn it down to keep your equipment safe.

While buying high-quality Stereo Amplifier Made in Germany is a good idea, before doing so you need to check the Impedance and Power rating of your speakers.

Common types of audio amplifiers

Audio amplifiers are considered to be central to any audio system, including televisions, public address systems and stereo systems.  A stereo power amplifier typically takes a low-level audio signal and amplifies it to a level that can drive speakers. Audio amplifiers basically magnify the power of an audio signal, and make it strong enough to move the cones in speakers to produce sound.

Today you can find many types of Audio power amplifier in the market. Each of them has their distinctive advantages, applications and properties. You must have a good understanding of each of these types to select the right amplifier for your audio system.

• Solid-State Amplifiers: Such amplifiers commonly employ semiconductor devices like transistors to amplify audio signals. They are renowned for their reliability, durability, and efficient power consumption.
• Tube Amplifiers: These amplifiers are among the oldest types of amplifiers and utilize vacuum tubes for amplifying audio signals. Even though they are considered outdated by some, tube amplifiers are popular among many audiophiles due to their warm, smooth, and rich sound quality.
• Digital Amplifiers: Also referred to as Class D amplifiers, these units convert audio signals into a digital format before amplification. Apart from being highly efficient, they also generate less heat in comparison to other amplifier types.
• Hybrid amplifiers: Such amplifiers blend the favorable traits of both tube and solid-state amplifiers. They offer the warm sound quality of tube amplifiers along with the reliability of solid-state amplifiers.

Broadly speaking, amplifiers play a crucial role in any audio system as they convert low-power audio signals into a format suitable for driving speakers, thereby enhancing our overall audio experiences. You need to properly identify your needs to find the right audio amplifier for your sound system. Such amplifiers and even HiFi speakers can be purchased online.
