The GaN400 is a “class-D” stereo power amplifier that utilizes GaNFETs (Gallium Nitride Field-Effect Transistors), an 850-watt RMS regulated power supply, a fully balanced topology and a low global ...

Class-D audio amplifiers represent a significant advancement in modern audio engineering by utilising high-frequency pulse modulation to drive output stages with exceptional efficiency.

See amplifier, PWM and PDM. Less Heat than Analog Because pulse modulation output signals are either on or off, Class D amplifiers produce far less heat than analog amplifiers.

Fig 2. The blue line shows the energy present in the 30-MHz band as produced by a conventional, unmodified Class D amplifier output. The brown line displays the same Class D output, but with a ±5 ...

“Extron pioneered the use of Class D amplifiers in AV applications and our engineers have continuously been developing unique, patented high-performance power amplifier technology,” boasts Casey Hall, ...

The new audio amplifiers support power levels from 15 W mono to 175 W stereo, and include features compatible with today’s home-audio speaker and microphone requirements.

The Class D amplifier was born in the middle of the 20th century, but didn’t begin to reach its full potential until much more recently. Over the last 20 years, the performance of Class D amplifiers ...
