Separate switcher mode — This is the secondary function of this button (see b). Press and release this button to select the separate switcher mode. The associated LED indicates if the separate switcher mode is on (when flashing). When the Mode button is released, the LED resumes input indication. i Composite video input — Buttons 5 through 8 select the input for the composite video sections of the MPX unit. The LEDs adjacent to each button (when lit) indicate which input has been selected for output.
Operation, cont’d Establishing a tie When you connect an input with an output in video or audio, you are establishing a tie. A tie can be a video-only tie (only a video signal is being transmitted through an output), an audio-only tie (only an audio signal is being transmitted through an output) or an audio and video (A/V) tie (a video signal and audio signal are being transmitted together or apart through one or more outputs). To establish a tie using the MPX 423 A, do the following: 1.
3. Press the Single button or the Separate button to select the desired mode. When you make a mode selection, the Single and Separate LEDs go out, and the Mode LED begins flashing. If a selection is not made within 30 seconds, the currently active mode remains active, the Single and Separate LEDs go out, and the Mode LED begins flashing. COMPUTER OUTPUTS/ AUDIO INPUTS 1 2 MODE SINGLE 3 4 1 2 Single button Separate button Press the Mode button.
Operation, cont’d Locking and unlocking the front panel Front panel security lockout prevents accidental switching of inputs from the front panel. When front panel security lockout is active, the user can only view the ties in each group; all input buttons and audio functions are locked. To toggle the front panel lockout on and off, press and hold the I/O button for three seconds. The Video and Audio LEDs flash twice to indicate a change in the front panel security status (on or off).
