Features of the V-4
Four-channels of video inputs
The V-4 provides two S-video inputs and four video (composite) inputs. Of the four channels 1
through 4, S-video can be used for inputs 1 and 2. If both S-video and video (composite) are input
to channels 1/2, the S-video input will take priority and will be automatically selected.
Two independent frame synchronizers
Even when using unstable video input signals such as VHS and Hi-8, the frame synchronizers
within the V-4 will correct the synchronization signal. This means you can use a wide range of
image sources without worrying about noise produced by degradation of the synchronization
signals.
High-quality digital effects
Effects are processed digitally. Diverse and high-quality effects such as Picture In Picture, Mirror,
and Multi can be independently applied to both channels A and B.
Simple operation
Switching and mixing video sources is extremely easy. The T-bar type video fader can be installed
in either the horizontal or vertical orientation, whichever you prefer.
Preview function
Before switching sources, you can use a preview TV screen to view the images being input on each
channel without affecting the output image.
Switching and effects synchronized to music
The V-4 lets you tap BPM (Beats Per Minute) to switch images or control effects. This is particularly
useful when music and video need to be synchronized, such as in a video jockey performance.
Control from external MIDI devices
The V-4 provides MIDI connectors. An external MIDI device can control effects and switching
images. Setup is particularly easy if a Roland or Edirol product that supports V-LINK is
connectedsimply press the V-LINK button on the control device.
