The first of a new generation of Procella power amplifiers, the DA4280 is a highly versatile, dynamic yet affordable high-performance audio solution. Designed with Pascal A/S in Denmark and using their highly-acclaimed amplifier modules, this four-channel amplifier is ideal for use with all Procella speakers, from the P1 to the P860.

Delivering a solid 280W at 8 ohms, the high-efficiency class-D DA4280 ensures a wide dynamic range with low-frequency impact and a transparent and musical sound quality that will satisfy the critical listener.


Procella’s DA4280 power amplifier provide affordable, versatile, and reliable high-performance audio power. Defining the standard in amplification for Procella loudspeakers and subwoofers, the DA4280 gives users a powerful platform to enable uncompromised performance with a Procella Audio speaker system.This high-efficiency class-D amplifier has extraordinary sound quality with enormous power reserves. As you would fully expect from Procella, the DA4280’s sound quality is utterly transparent, with an extremely wide dynamic range and robust low-frequency impact. Four channels of amplification deliver a solid 280W each at 8 ohms which suits most Procella loudspeakers from the P1 to P28 or even our full range loudspeakers if bi-amp outputs are provided with filter settings (such as a Trinnov Altitude).
