Input selection

Switching is accomplished from within the Universal Switcher Control Program by selecting which input to tie to one or both outputs (see figure 4-3). The top row of inputs is available for output 1 and the bottom row of inputs is available for output 2. The same input can be routed to both outputs, but an output can only be tied to a single input.

To tie an input to an output:

1.On the Universal Switcher Control Program main window, click on the numbered input button you want to tie to each output. Checkboxes control whether the switcher selects video, audio, or both (system default is both video and audio) and indicators (green for video and/or blue for audio) will light to indicate your selection.

2.To switch the audio signal independently from the video signal (audio breakaway) click the Video or Audio checkbox as desired (the default is both boxes on).

Input selection from the switcher’s front panel will cause the program to “light” the associated indicators in the program to reflect the change.

Muting the audio signals

To mute one or both of the switcher’s outputs:

1.Click on the MUTE button for the selected output(s) on the Universal Switcher Control Program main window (figure 4-3). An associated orange indicator will “light” to indicate that the audio and/or video output is muted.

2.To unmute the audio signal, click the MUTE button again to uncheck the audio mute for the selected output.

The MUTE function is not available from the switcher’s front panel and can only be achieved through RS-232 control. When muted, the LED’s for the muted inputs on the front panel will be off.

Setting audio levels

The box between the video and audio checkboxes displays the audio gain (or attenuation) setting for the currently selected audio input.

To set or changes the levels for audio inputs:

1.From the Universal Switcher Control Program main window (figure 4-3) click on Configure.

2.From the drop-down menu, select Audio Inputs to display the Configure Audio Options window (see figure 4-4).
