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

connected—simply press the V-LINK button on the control device.
