C2-2150A Advanced Features - In addition to all standard C2-2100A features. The Key Mode allows computer graphics to be keyed over an external Composite or YC signal. The keyed image may be faded in and out. Due to the 4:4:4 sampling format, precise keying at the pixel level can be achieved. The Mix Mode permits Seamless Cut, Fade or Wipe transitions between input sources. The PIP Mode allows either of the computer inputs to be inset in a window over either of the video inputs or vice versa. The PIP window may be placed anywhere on the screen. The C2-2155A provides an SD/HD-SDI Output as well as all the other features of the C2-2150A.

Input Expansion is possible by using the optional S2 Series Input Expansion Switchers for DVI or RGB/YPbPr. These units link to C2 unit via an OPTIONS Interconnect Cable and become an integral part of the main unit from a control and operational standpoint. The routing of these additional inputs is controlled directly from the control system of the C2 unit and multiple different S2 models may be simultaneously connected.

Advanced Stereo Audio processing and switching is available via the optional S2-106AD Input Expansion Switcher, providing six differential audio inputs, which can be used for low impedance balanced or high impedance unbalanced sources. The user controls audio level, audio sampling frequencies and up to 999ms of adjustable audio delay independently for each input. The unit has numerous choices for audio I/O connectors, including a terminal block. The S2-106AD connects to the C2 unit via the OPTIONS interconnect cable and is then fully integrated into the control system of the host unit.
