What is Amplifier?

Amplifier (abbreviated as "Amp") is a device that amplifies and regulates audio signals.

Companies often produce Amps that come with Speakers, integrated together in a housing to form a set of equipment, which can be connected to the signal source and used immediately.
When listening to music, watching movies... from sources such as computers, phones... we just need to connect to a device commonly called a "Speaker" to be able to emit sound immediately. But actually, inside the "Speaker" is a set of devices including Amp (amplifies the signal, adjusts the signal up - down, bass - treble...) and Speaker (emits sound after the signal has been transmitted). pass through Amp) combine together.

There are 2 types of Amps:

1. Amp for audio: Designed to receive signals at mic level, equivalent to the output port (headphone) of phones, computers, disc players, music players, organs... these Amps are often used to listen to music, watch movies, sing karaoke...

2. Dedicated musical instrument amp :

- Instrument amps are specifically designed for certain musical instruments. Special instruments such as classical/acoustic guitars with pickups, electric guitars, bass guitars, silent guitars, electric drums... require a suitable specialized Amp line to create the right sound quality for the instrument.

In addition, there are also some types of Amps that are designed to be adjustable to suit many different types of musical instruments.

- Specialized musical instrument Amp sets are often produced including Amplifiers and Speakers, integrated together in a housing to form a set of equipment called a Combo. For example: Fishman Loudbox mini, Alesis Strike, Marshall MG30FX...

- In addition, companies also produce individual Amplifiers and Speakers.

+ Individual instrument amplifiers are called Heads, which only have the function of amplifying signals and adjusting audio signals, but do not emit audible sound because they do not have speakers. For example: Marshall Code 100H, Boss Katana Air, PRS Mark Tremonti MT15 Head...

+ Individual speakers are called Cabinets, which have the function of receiving signals from the Amplifier and emitting sound after the Amplifier has amplified the signal. The cabinet also cannot produce sound if connected directly to the instrument without going through an Amplifier, because the signal sources from the instrument are usually of very low intensity, requiring an Amplifier to amplify the power. For example: Marshall Cabinets Code 412, Yamaha Cabinets THRC212...

To use, we must combine a Head with one (or more) Cabinets.

There are four types of guitar amplifiers: Solid state (analog), tube, modeling (digital), and hybrids.

Solid-state amps.

These amplifiers are called Solid-state because they use transistors for the preamp and power sections. They are very reliable and rarely need repairs. They usually have a very clear tone, although many sounds also have “distortion.” These amplifiers are popular with players looking for an amplifier for performing.

Tube amps.

Tube amplifiers are favored by many guitarists for their warm, rich sound and “organic” distortion. Tube amplifiers typically sound louder than Solid-state amplifiers of the same power and have a distinct “feel” that you don't get from a Solid-state amplifier. Most tube amps have separate channels that can go from clean to distorted in an instant. Tube amp performance can degrade over time, so tubes need to be changed from time to time.

Modeling amps.

Modeling amplifiers use digital processing to simulate the sound of old-fashioned tube amps. Using software that “models” the sound of tube amplifiers, these amplifiers put the sound of multiple amplifiers into one amp. Modeling amplifiers are programmable and often have built-in digital effects such as delay, chorus, etc. Some include digital or analog outputs with speaker simulation for streaming directly into a recording interface or system. PA.

Hybrid amps.

Combining the best of each type of amplifier into one amp, these amplifiers use actual tubes combined with transistors.

Viet Music trades and distributes specialized musical instrument amplifier product lines from famous brands (Marshall, PRS, Yamaha, Boss...) for each different type of musical instrument.
