The phrases amp and preamp will be familiar to anyone setting up a studio, whether professionally or just for fun at home. Although the two devices have similar-sounding names, they serve different purposes.
Sound is a result of several diverse factors coming together. The amplification process is one of the most significant of these.
Simply put, an amplifier takes a sound signal and increases it to levels that are audible and listenable. Despite the fact that this explanation is straightforward, the procedure involves much more.
In this essay, we'll describe how the two are different from one another. What's more, do you require either or both of them? Because their prices are not cheap.

What is an amplifier?
A device designed only for driving speakers is referred to as an amplifier. It lacks a linked input for receiving signals from other devices like media players or cable boxes. The speaker terminals are where all inputs are hardwired.
It can be found in any device with speakers and is not exclusive to home theaters. The strength of an amplifier will change depending on what it is used for. The weaker signal from the preamp is further amplified by a standard amp, or power amp, in the signal chain to provide a signal potent enough to be played and heard by passive speaker systems.
Any system that contains passive speakers needs power amplifiers. These speakers need to have the signal they receive amplified because they are not powered. Similar to this, performers who use electric instruments like electric drums and guitars require a power amp so that their audiences can hear them.
What is a preamp?
One of the more confusing components of a home theater system is the preamp. The most fundamental function of a preamp is to boost particularly weak input signals such that they are consistent with the other signals being processed by the amplifier.
Preamplifiers are electronic components found in a wide range of audio equipment, including computer sound cards, USB microphones, DJ mixers, large-format consoles, and audio interfaces.
The wonderful thing about them is that, even if you weren't entirely aware of it, there's a decent chance you've used one. Most likely, you have an audio interface, a microphone, and have used the microphone to record using the interface. That is the preamplifier's single most significant application. In essence, it increases a quiet signal's volume to pleasant, recordable levels.
Preamp and amp main differences
It is understandable to question what makes them so different when you take into account the fact that they are both amplifiers and that they are both used to amplify a signal.
Put it simply, their position in the recording/playback chain accounts for a significant portion of what distinguishes them from one another. If you are unfamiliar with the term "chain," it simply refers to the path the signal follows through your apparatus.
An amplifier raises music to perceptible levels, whereas a preamp boosts sound to line level.
Preamps are more compact devices that consume less power than amps, which are bulkier, more powerful devices that produce more noise.
Preamplifiers are used to improve inputs with weak signals, such as those from microphones, whereas amplifiers handle stronger signals, such as those from mixers and electric guitars.
These are where they diverge from one another the most. Remembering that a preamp is used to amplify weaker signals is of utmost importance. In the absence of any equipment that generates a weak signal, a preamp is not necessary.
Do I need to purchase both an amp and a preamp?
It's not a bad idea to have both, but if you have to choose one over the other, go with the preamp.
It may be used to record a variety of sounds with acceptable sound quality, a preamp is a far more important instrument for music production (but you'll still need a microphone).
Preamps are excellent for amplified sounds like bass and electric guitars as well as vocalists, acoustic instruments, field recordings, and even noises from power amplifiers.
Without the use of an additional external power amplifier, active speakers can be connected directly from a preamp. only in active speakers when the drivers each have their own built-in power amplifier.
But when you only have a passive speaker, you need both. Each performs the function that the other cannot, as is evident.
A power amp is required to drive speakers; a preamp lacks the power to do so.
A preamp is required to provide the line level signal that a power amp requires.
