The 4.8SP has four inputs and eight outputs, while the 3.6SP has three inputs and six outputs. The front panel interface allows quick access to all control parameters by offering dedicated function buttons, eliminating the need for hidden sub-menus. For even faster set-ups and stronger visualization of Input / Output routing, EQ, and Filter curves, a USB port is provided for use with Windows™ Software. Full control by third-party controllers is also available via RS-232.
