About Amplifiers & Pre-Amps

Whether you’re resurrecting your record collection or boosting the power of your MP3 files, the amplifiers and preamps category is where you want to be! With top of the range models and great budget-friendly options in equal abundance, this OnBuy category is your one-stop shop for signal boosting greatness.

Why do I need an amplifier?

You know why you need CD players or record players to enjoy your music collection, but what’s the point of an amplifier? Simply put, the amplifier’s job is to take quiet sounds and make them louder.

There are two main kinds of amplifiers: regular amplifiers (aka power amplifiers) and preamps. The purpose of power amplifiers is to boost the sound of a line signal so that it can be sent to speakers. Preamps boost the sound of acoustic devices like record players and condenser microphones to a line signal level. The reason you might need two amplifiers is because the amount of electricity used by amplifiers can cause a lot of interference in your music. Preamps use very little power by comparison, so your music is unaffected. Many amplifiers have preamps built into them, so look out for those.

Even if your audio device generates enough juice to properly power a pair of speakers, you might still need an amplifier. This is because, as well as boosting the volume of audio signals, some amplifiers act as a hub for you to connect all of the parts of your Hi-Fi system together. These amplifiers have the proper speaker cable ports required to use top of the line speakers, and you can use them as both a record player amplifier and CD player amplifier simultaneously.

Amplifier designs

There are lots of amplifier designs available at OnBuy. We’ve already mentioned one variety of amplifier - those that combine amplifiers and preamps together into a signal unit. They’re known as integrated amps and they’re great for beginners.

True audiophiles, however, prefer to buy their amplifiers and preamps separately. This reduces any chance of audio interference to a minimum. Buying amplifiers and preamps separately also allows you a lot more control over how your music sounds. Many amplifiers have great EQ opportunities. Boost bass, fine tune the treble and adjust the speaker balance with just a few turns of a knob. Many amplifiers have extra features like Bluetooth connectivity as well.

Frequently asked questions about amplifiers

Where is an amplifier used?

An amplifier is an electronic device that increases the current, voltage, and power of a signal. Amplifiers are usually used in wireless communications and broadcasting and are an additional piece of kit for your turntable. 

Can an amplifier change the quality of the sound?

An amplifier can improve the quality of the sound in a lot of ways. Amplifiers are made to change the volume, but they can also affect the sound tone and linearity. It really depends on the type of amplifier that you get, the setup, room acoustics and other external factors.

How long will my amplifier last?

An amplifier is a really useful tool to get for your systems. They can improve the quality of the sound your setup offers, so if you're a hardcore music buff, getting one is well worth the money. An amplifier should last 10 to 20 years. The hi-fi systems - we're talking about the speaker, turntable, and amplifier parts of the system - should last you at least a decade if you properly take care of them.
