The T-BARand the PLAY button run the same transition, except that the T-BARlets you manu- ally control the speed at which the transition runs.

SELECTING SOURCES

Now that you understand the distinction between the CURRENT and NEXT source, you need to know how to select sources for each. Use the CUT and NEXT buttons on the MX-4 DV keyboard to select sources.

Use to change the CURRENT source

Use to select NEXT source

Use the CUT buttons to select the CURRENT source. The four buttons labeled A, B, C, and D corre- spond directly to the Input Source Previews on the Preview Screen (refer to page 36) and to the MX-4 DV’s four channels. Use the BACKGROUND button to select a solid color background rather than an image coming from a source device (refer to “Using Color Backgrounds” on page 42). When you press any CUT button, the output video cuts to the new source and the indicator light below the CUT button glows steadily.

After selecting the CURRENT source, use the NEXT buttons to select the NEXT source. The but- tons are labeled the same as the CUT buttons. When you press any NEXT button, the indicator light above that button flashes.

USING THE VIDEO/AUDIO SELECTOR

The VIDEO/AUDIO selector controls which parts of the input signal get used from any given source.

You can set the VIDEO/AUDIO selector to any of three positions — VIDEO only, AUDIO only, or both. Press the button as required to turn on the Video, Audio, or both lights.

VIDEO – Video changes, audio does not. Video light only is illuminated.

AUDIO – Audio changes, video does not. Audio light only is illuminated.

BOTH – Audio and Video both change. Both the video and audio lights are illuminated.

Many sources (such as pre-recorded video tapes) carry both video and audio signals. Other input sources (such as a compact disc player) carry only audio signals, and some sources carry only video signals.
