Bryston BD 225 Amplifier

Bryston is pleased to announce our first ‘Class D’ amplifiers.

A Class D amplifier is a type of audio amplifier that uses a digital switching technology to amplify audio signals. It is also known as a switching amplifier or a digital (erroneously) amplifier. Unlike traditional analog amplifiers, which use continuous voltage waveforms to amplify signals, Class D amplifiers employ a more efficient method that switches the input signal on and off rapidly.

One of the major advantages of Class D amplifiers is their exceptional efficiency. Unlike traditional amplifiers, which operate in the linear region and dissipate a significant amount of power as heat, Class D amplifiers utilize switching technology to achieve high efficiency levels. By employing pulse width modulation (PWM) techniques, Class D amplifiers rapidly switch the output transistors on and off, effectively creating a series of pulses that represent the audio signal. This switching action allows the amplifier to deliver power to the load with minimal power loss, resulting in higher efficiency. The efficiency of Class D amplifiers can exceed 90%, significantly surpassing that of Class A, Class B, and Class AB amplifiers.

All Bryston power amplifiers use what is called a linear toroid power supply with multiple capacitors to ensure the instantaneous transient power required by very dynamic content is easily accommodated.

The Bryston Class D amplifiers use a ‘common chassis’ with the option of 1, 2,3, 4, 5, or 6 independent Class D modules  This provides real flexibility for multiple channel Active or Passive audio systems or custom install Zone applications.
