NEWS

SounDigital presents the revolution in amplifier production!

GaN is the big star when it comes to amplifier performance! With its unique

ability for electronic mobility, it paves the way for unparalleled sound power. Get

ready to immerse yourself in a musical universe of high fidelity and clarity with

SounDigital, where every note comes to life with stunning precision. Your

listening experience will never be the same!

History of gallium nitride (GaN)

The use of gallium nitride (GaN) in amplifiers is a relatively recent but extremely

significant development in the field of power electronics and audio amplification.

Gallium nitride was discovered in the 1960s, but research and development of

the material as a semiconductor gained momentum in the following decades.

GaN has shown promise for high power and high frequency applications due to

its unique characteristics such as high electron mobility and ability to operate at

elevated temperatures.

In the 1990s and 2000s, GaN technology continued to be developed and

improved. Researchers and engineers have focused on improving the

crystalline quality of the material and developing techniques for growing GaN

crystals on suitable substrates.

In recent years, the adoption of GaN power amplifiers in the audio market has

grown significantly. SounDigital has taken advantage of GaN to create more

efficient, smaller amplifiers with better sound quality.

Tune in to the future of sound!

The electronic revolution has arrived at SounDigital, and GaN is the star of this

transformation! With high-performance amplifiers, unrivaled durability and eco-

consciousness, the future of sound is brighter than ever. Get ready for an

extraordinary sound experience that pushes the boundaries of the ordinary and

delivers the sound of your dreams. Tune in to GaN and open your ears to a new

musical dimension!

ADVANTAGES

Advantages of using SounDigital amplifiers with GaN technology:

SounDigital's GaN-based power amplifiers have several advantages that make

them attractive for use in audio systems:

Reduced size and weight

Due to the high efficiency and ability to

operate at high frequencies, SounDigital

amplifiers with GaN technology can be

designed to be smaller and lighter

compared to traditional amplifiers.

High energy efficiency

GaN has a high electron mobility, which allows GaN power

amplifiers to convert significantly less electrical energy into

heat. This results in higher energy efficiency, minimizing

power losses and making them more sustainable.

High switching speed

SounDigital amplifiers with GaN technology are able to

operate at high frequencies with a faster response

compared to other semiconductors such as silicon. This

results in lower signal distortion and a more accurate

frequency response, which contributes to better sound

quality.

High temperature performance

SounDigital amplifiers with GaN technology can operate at

higher temperatures without significant loss of

performance, which is beneficial for applications where

heating is a challenge, such as in high-power amplifiers.
