Index.......................................................................................................98 8 Welcome Thank you, and congratulations on your choice of the Edirol V-4. The V-4 is a video mixer/effects processor that delivers image quality rivaling professional equipment, and provides four channels of video input. With a rich array of inputs and easy operation, the V-4 allows performances and presentations that include images to be made more expressive than ever before. The V-4 can also be controlled from external MIDI devices. Images projected on the stage can be controlled while you play an instrument, adding impressive impact to a stage performance. We hope you will enjoy the V-4's versatile video functionality in a wide range of applications. 9 Features of the V-4 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. 10 What is V-LINK? What is V-LINK? V-LINK ( ) is a function that links music and video performance, making it easy to create a variety of visual effects linked to the expressive elements of a performance. By using V-LINK, musical instruments and music production equipment manufactured by Roland or Edirol can control video images without experiencing any loss in the quality of their inherent function (i.e., producing sound).

Typical connection example DV-7PR VCR DVD Camcorder Projector Preview Monitor * * * * The V4 does not have audio inputs so will not mix audio. Audio outputs can be connected directly to speakers or via an audio mixer if mixing of audio from multiple devices is necessary. No video cables come with this product. Please use appropriate video cables for connection with source devices or TV monitor/Projector. It is recommended to use composite cable rather than S-video cable where you need to connect devices long distances (unless using S-video amplifiers). If devices are installed closer to the V-4, it is recommended to use S-video cables so that you can obtain better image quality. If both video (composite) and S-video signals are input simultaneously to the same channel (channel 1 or 2 only), the Svideo signal will take priority. 17 Connecting peripheral devices Video signal flow The video signals received from the four input jacks are assigned to channels A or B of the video mixer. (These assignments are made manually.) The signal of A and B channels are processed by the video mixer section, and sent via the output fader to the output jack.
