he Extron IN1508 is an eight input, AV presentation switcher that accepts and scales a wide range of video signals to a common, high resolution output rate. It can accommodate two composite video, two S-video, one standard or high definition component video, one DVI-D, and two RGB computer-video sources. Eight input stereo audio switching is also provided with independent gain and attenuation control. The ability to accept multiple inputs of varying formats along with many other convenient and useful features make the IN1508 a true presentation switcher that is an ideal centerpiece for mid-sized AV systems.
