The Edirol V-4 is a 4-channel video mixer designed especially for portable or fixed installation use. It is ideal for nightclubs, places of worship, theaters and other live performance venues. The compact design of the V-4 gives you the freedom to make your video sources come alive.

For cutting-edge multimedia artists, the V-4 offers V-LINK, an exciting new feature from Edirol and Roland that provides realtime performance control over digital video for the ultimate in creative expression. V-LINK allows the user to trigger clips, perform video effects and transitions in realtime when connected with the Edirol DV-7PR (sold separately). The V-4 video mixer also has MIDI in/out/through, for realtime or sequenced control of video sources with effects and transitions.

The V-4 is equipped with four composite (RCA Pin) inputs plus two S-video (Y/C) inputs. V-4 offers scene transition of the four video sources with Dissolve, Wipes (with a total of about 200 variations), and Switching. The V-4 outputs the same video source to all the three jacks (Composite x 2, S-video x 1), for simultaneous monitoring and displaying, without resorting to external distribution boxes.

The input video sources are processed completely in the digital domain, and give professional video quality (13.5MHz, 8-bit, 4:2:2, DV quality). Ideal for use on large screens, and because the V-4 internal processing is digital there is no quality loss.The input sources go through independent 2-channel TBC (Time Base Correction) circuits to correct the time code, independent 2-channel Frame Synchronizers are also applied to the two sources at this stage. These processes enable smooth transitions and Dissolves, and ensuring stable images all the time. V-4 features independent 2-channel Video effects that include a rich selection of digital effects (refer to spec sheet). The V-4 also features composition effects such as Picture-in-Picture, Chroma-key, and Luminance-key. The effects are recallable by a single button press. Professional-use T-Bar cross fades for quick and intuitive operation. A V-4 innovation is that you chose to attach the fade however you like, either, vertically as standard for video mixer, or horizontally as a DJ mixer fader. The fader resolution has over 100 steps and offers extremely smooth transitions. Its metal body as well as its fader is strong and durable to be used in your active performance. V-4 is designed for its functions and operations to be clear from the front panel. Because it is simple to use its easy-to-use operation will enhance your realtime performance. Most of the V-4 functions can be selected and controlled without resorting to the manual.
