Vanguard Dynamics - DA-2.1 - 2-Channel Satellite and Subwoofer Amplifier

Vanguard Dynamics - DA-2.1 - 2-Channel Satellite and Subwoofer Amplifier

The Vanguard Dynamics DA-2.1 Digital Amplifier is a great solution for indoor, outoor and even commercial applications, providing power to satellite speakers as well as a subwoofer. With multiple digital and analog inputs, the DA-2.1 is compatible with legacy audio sources as well as modern digital audio sources. Designed as a 1U rack-mountable amplifier, easily tuck the DA-2.1 into an equipment rack.

At the heart of every great audio system is a power amplifier. It’s what brings the system to life. Vanguard Dynamics amplifiers are carefully designed and engineered to provide incredible acoustics while performing reliably. The Vanguard team has decades of experience in amplifier design and has put all of their experience into this outstanding line of amplifiers.

Each part of the amplifier has been carefully considered and built for the best possible performance. That’s why in many models where others would use digital power supplies Vanguard Dynamics has chosen toroidal copper power supplies. That’s also why while others manufacture in large scale facilities they instead choose a smaller manufacturing partner that only does amplifiers and has a decades long history of manufacturing some of the best amplifiers ever made. Vanguard Dynamics also back all of this confidence in its performance and reliability with a unique 5-year warranty
