The Acurus ACT 4 is a 20-channel immersive audio preamp processor, designed to be the heart of a modern home cinema. It combines high-end audio performance, flexible control and HDMI 2.0b with Dolby Atmos and DTS:X decoding.

A full-colour touch display makes setup and daily use simple, and the web interface lets you control the whole theatre from a phone or tablet anywhere in the home. Balanced and unbalanced outputs suit almost any system, and Acurus's own ASPEQT room correction is supported.
