ACOUSENCE pow-amp 4 – High-end 4-channel power amplifier for maximum dynamics and precision

The ACOUSENCE pow-amp 4 is an innovative high-end four-channel power amplifier that combines state-of-the-art PWM amplifier technology with uncompromising sound quality. Designed for demanding hi-fi systems, active speaker concepts, and professional audio applications, it offers exceptional dynamics, control, and efficiency.

Analog pulse-width modulation (PWM) enables exceptionally fast and precise signal processing. As a result, the pow-amp 4 combines the fine detail and speed of high-quality tube technology with the power and low distortion of modern transistor amplifiers.

A key feature is the individual impedance matching of the output filter to the respective loudspeaker. This optimization improves the temporal response and ensures a particularly natural, controlled, and spatial music reproduction.

Through its fully balanced signal path, high-quality input stages, and a powerful power supply, the ACOUSENCE pow-amp 4 delivers an impressive combination of transparency, power, and musical precision. With four amplifier channels, it is ideal for demanding stereo, bi-amping, or multi-channel systems.

ACOUSENCE pow-amp 4 – High-end amplifier technology for uncompromising control, highest resolution, and authentic musical enjoyment.
