Your Ultimate Guide To Buying A Power Amplifier.

 

Martin Audio aces the game when it comes to making power amplifiers, while Adastra, Citronic and Crown are creating a tough competition by bringing nothing but the best at impressive rates. With immense choices comes an even big dilemma to pick the best suited to your needs. Thus StageGear brings to you, the ultimate guide to buying the best power amplifier specific to your purpose and a pre-set budget.  

In no particular hierarchy, here are some POC (Points Of Consideration) before/while buying a power amplifier.  

Set A Budget

Refrain from overspending on a power amplifier. Be realistic with your choices by pre-setting a budget that you can free up to buy audio equipment like an amplifier. When you are open to possibilities, you will find out a lot of suitable product ranges at affordable rates.

Specify Your Purpose From The Amplifier

A lot of audio systems require power amplifiers. Although several loudspeakers have in-built amplifiers, here we will be talking precisely about external amplifiers. Is it to amplify a musical instrument like a guitar? Or to implement with your home theatre system, a public address system or a car audio system? Defining a purpose often creates a roadmap to wiser choices. 

Understanding Impedance And Output Power

Impedance in physics is a measurement of a system’s opposition to alternating current when voltage is applied. It comprises electrical resistance and reactance and is denoted with ohms. Although impedance is frequency oriented, speaker impedance is offered as a nominal value rather than detailed graphs. Nominal impedance is an average designed impedance of an audio system.

In power amplifiers, impedance matching is mandatory for transferring maximum power from the amplifier stages to the loads. Impedance is also the solution to reduce noise distortions and coupling in amplifier stages. The output impedance ranges - 1ohm, 2ohms, 4ohms, 8ohms and 16ohms. If the impedance is too low, the power transfer will overload the speaker and the amplifier to the extent of the damage.

In a power amplifier, the output power is measured in watts. It is indeed a factor of importance in the system. Greater the output power specification, the more the signal power and eventually a greater perceived volume. But the output power may vary, some brands provide peak values while others give RMS (root mean square), continuous or other ratings.

While peak power is the maximum output power of the power amplifier, continuous power is the power rating an amplifier can output constantly without overheating. Ask the expert about impedance and output power.

How Much Power Do You Need?

The calculation entirely depends on the purpose of the power amplifier. It is ideal to look at the speakers first and then pick a compatible power amplifier capable enough for driving them.

Brands To Trust

Martin Audio

Martin Audio makes the finest range of power amplifiers for versatile purposes with superb audio performances in a lightweight cost-effective range. The brand is one of the rare pioneers delivering top-notch power amplifiers in the UK. Mostly inclined toward a powerful range of loudspeakers, sound processors and amplifiers. Martin Audio 4 Channel Class D Amplifier is the one to beat when it comes to lightweight yet powerful solutions for PA installations. Browse through Martin Audio power amplifiers.  

Crown

Crown facilitates the Live and public address domains with impeccable power amplifiers. Doing complete justice to the cost of the audio pro systems, the brand thinks as their customers. This customer-centric approach makes them build products that serve their clients better. The power amplifier is the comfort zone of the brand. Have a look at Crown’s amplifier series.

Adastra

Although the brand is renowned for its versatile product range, we cannot forget about the power/stereo amplifiers. Adastra produces the most agile range of amplifiers - from PA amplifiers to home stereo amplifiers, WiFi-based multi-streaming amplifiers and mixer amplifiers. The brand is popular to produce the most affordable range yet premium range.  Make your pick from the Adastra selection.

Wrapping Up

All the above considerations can go in a loop. For instance, you can specify the brand and then find ways to reserve a budget for it. Or you already have a budget to lead you to a choice. No matter what the circumstance is, StageGear gives you a portal to browse through the entire collection from your favourite brands, so you do not miss out on even a single option.
