The Platinum routing switcher system provides matrix expandability beyond 8x8, to 512x512 in a single frame. The 8x8 building block provides ideal growth and flexibility for mixed applications such as high definition and serial digital interface, and other integrated processing opportunities such as analog and/or digital conversion. With its ability to route signals ranging from 3.0 Mb/s to 2.97 Gb/s, the Platinum router offers a clear growth path from lower bit rate signals to high bandwidth, high definition format signals. This router will also handle both AES and polarity sensitive ASI/SSI signal formats.
