The ACT 4 represents a revolution in 3D-audio home cinema processors. Designed to be the center of a modern UHD home theater, the ACT 4 combines ultimate audio performance, control flexibility, and the absolute latest immersive sound technologies. With 20 channels of immersive audio the ACT 4 meshes the celebrated engineering of Acurus with the power of advanced cinema technology--all in perfect harmony.
Setting a new standard for ease of installation and use, the ACT 4 features an intuitive, full-color, touch-sensitive front panel display simplifies setup and operation. Controllable via 3rd-party systems, the ACT 4 also offers web setup and control which enables operation of an ACT 4 theater from anywhere within the home via mobile device. The ACT 4 has both balanced and unbalanced outputs which allow for flexibility in any application.
An ACT 4 processor features 15 main outputs and 1 subwoofer output for native decoding and rendering of immersive audio streams with 4 additional subwoofer outputs for larger speaker layouts such as 9.5.6 or 9.7.4.
The ACT 4 supports Acurus' own room correction technology, ASPEQT, an acoustic optimization system which is incredibly simple to use, yet powerful enough for the most challenging cinema environments.
To make the very best audio connections, Acurus has two custom-made cables included with this product. The DB9 to XLR 4-channel output adapter cable, called the TETRA, is a must if the maximum channel count is desired for the ACT 4 or MUSE immersive processors. For single output channels, the Acurus MONO XLR cable is the best choice.
