Switching Between A Bus and B Bus
When no previewing is needed, you can perform switching by using only the input selector buttons. This lets you execute
a transition more easily and rapidly. You can do this in the LVS mode.
In the LVS mode, B Bus is handled as main video and A Bus is handled as insert video. Moving the video fader to the A Bus side
superimposes the insert video selected on A Bus over the main video of B Bus. P in P (Picture-in-Picture) settings are also enabled.
The video selected for A Bus is output from the A/B MIX PVW connector.
1. Move the video fader to the B Bus side.
2. Select the input channel.
Press the B Bus input selector buttons in succession to switch the video.
*The transition-effect and transition-time settings remain in effect for switching performed in this way. Also note that no channel can be selected for
A Bus while a transition effect is being applied.

When the LVS mode is enabled and the video fader is set to A Bus, using the B Bus input selector buttons to switch the channel makes
the output video change in the sequence shown below.
1.Selected channel on A Bus
2.Previously selected channel on B Bus
3.Newly selected channel on B Bus
*At step 2, the picture is displayed briefly, then immediately changes to 3.
*Between 1 and 2, the transition-effect and transition-time settings have no effect.
*between 2 and 3, the transition-effect and transition-time settings are applied.
Let’s say that you have selected input 2 on A Bus and input 1 on B Bus, and the video fader is set to A Bus. In this state,
the video for input 2 is output. If you now change the selected channel for B Bus from input 1 to input 3, the output
picture changes in the sequence shown below.
