Dear customer
Congratulations on acquiring your Soundigital! You've just purchased a
product of high quality and technology. The Soundigital products are
developed to assure maximum efficiency and reliability to your sound
system.
Class D Amplifiers:
The main characteristics of Class D amplifiers are: audio quality,
efficiency, versatility and compact design.
Here are the advantages of these characteristics:
- Audio Quality – Class D amplifiers used to have a limited response in
the past and they used to have a worse performance regarding higher
frequencies than Class AB amps, despite being more efficient.
Introducing new technologies, Soundigital developed a Class D
amplifier superior to the Class AB ones in efficiency and performance.
- Efficiency – The Soundigital Class D amplifiers have a total efficiency
(power source + output) higher than 70%, assuring a lower than
expected battery drain and heating.
- Versatility of uses –The flat response of all the frequencies of
Soundigital amplifiers allows them to be used in all the kinds of
systems: SPL, Sound Quality, Trio Eletrico and Pancadao, meeting the
needs with extreme quality.
- Compact design – The high efficiency and technology allow our
amplifiers to be really compact, making it easy to install them in
vehicles where you have limited space.
