About Class T
How does a digital amplifier work?
Digital Amplifiers make use of high frequency, high power MOSFETS to transfer the audio signal to the speakers.
By working at frequencies far above the audio band, they can build a true analog reproduction of the sound at a much higher power.
Compared to analog Amplifiers, Digital Amplifiers are less fussy about the properties of the speakers you connect or how you connect them.
Digital Amplifiers are characterised by their small size and high efficiency. The sound is usually very dynamic, giving an auditorium feel to even a small room.
How is class T different?
Class T is a type of proprietary digital amplifier that uses amplifier chips from Tripath.
Its referred to as Class T rather than Class D to separate it from traditional class D amplifiers.
Previously, digital amplifiers have been unable to compete with analog amplifiers in terms of sound quality, mainly due to rounding errors in the digital input stage.
Advances in technology have allowed the class T design not just to compete with analog designs, but better them.
The result is a sound quality that is as good as the highest end analog amplifiers, but the efficient design reduces size and cost.
