Troubleshooting....................................................................................28 Main specifications...............................................................................29 6 Main features The V-1 is a video mixer that lets you switch among four channels of video at will. Four channels of video input The V-1 provides four channels of video input jacks, with both video (composite) and S-video inputs provided for each channel. Both video (composite) and S-video connectors are also provided for the output as well. Two independent frame synchronizers Even if the video signals you input are unstable, the built-in frame synchronizers will correct the synchronization signal of the video. You can work without having to worry about noise caused by synchronization problems. Simple operation Since illuminated buttons provide confirmation of the current operating status, switching and mixing images is easy. Picture-In-Picture The Picture-In-Picture effect lets you show a miniaturized image inside a different image. Superimpose The Superimpose effect lets you remove a specified portion of an image and combine it with a different image. This provides an easy way to superimpose text from the video output of your computer. V-LINK capability The V-1's MIDI connectors let you control the V-1 from a MIDI-equipped electronic musical instrument or other external MIDI device. When connected to a Roland or Edirol product that supports V-LINK, the V-1 can be remotely controlled as a VLINK device. 7 Examples of use In a concert The V-1 is a great addition to a concert performance. You can switch between images taken from video cameras at various angles, or use the video fader to smoothly move between them. The names or profiles of performers can be combined with live video using the Superimpose feature. fig.02-01.eps · See p. 16 for more about transitions. · See p. 20 for more about Superimpose.

You can connect up to four video playback devices, such as a video camera, VCR, or DVD player, and take advantage of a wide range of creative possibilities. fig.06-02.eps Video playback device OUTPUT L R Video S Audio DVD PLAYER VTR Video camera PC Using the cable hook To AC Concent AC adaptor Video output device INPUT L R Video S Audio Television Television Video projector Set the TV's input select to Video or External Input 12 Connections 1 2 Use the appropriate type of video cable to connect the video (composite) or Svideo output jack of your video device to the V-1's input jack. Use the appropriate type of video cable to connect the V-1's video (composite) or S-video output jack to the input jack of your video output device (e.g., television or video projector). * The V-1 supports only signals that comply with NTSC/PAL formats. Operation may not be stable if non-compliant signals are input. * If a signal is input to both the video (composite) and S-video input jacks, the S-video signal will take priority. * To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections. * The video cables needed for making connections are not included with the V-1. You will need to obtain commercially available video cables. * If the cable length is not too long, you will obtain a better image by using an S-video cable to make connections. However, if you cannot avoid using an extremely long video cable, use a video (composite) cable rather than an S-video cable. To prevent the inadvertent disruption of power to your unit (should the plug be pulled out accidentally), and to avoid applying undue stress to the AC adaptor jack, anchor the power cord using the cord hook, as shown in the illustration. The V-1 does not contain an audio mixer. Connect the audio output of your video device directly to your audio system. If you want to mix the audio from two or more sources, you will need to use a commercially available audio mixer. 13 Turning the power on Once the connections have been completed (p. 12), turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to TV monitor and other devices. 1 Check the power cable Make sure that the power cable from the AC adaptor is firmly plugged into the V-1. fig. power button.eps 2 Press the POWER button located on the rear of the V-1. fig.06-03.eps * Due to its circuitry-protection feature, the V-1 requires about five seconds after power-up before it is ready for normal operation. * The startup screen will appear in video (composite) output 2. This screen lets you check the current system settings. Turning the power off 1 Press the rear panel POWER button Press the POWER button located on the rear panel. All buttons and indicators on the front panel will go dark. About the grounding connector Depending on the conditions in which you use it, the V-1's panel may feel slightly "gritty" to the touch. This is due to an extremely low level of static electricity that poses absolutely no danger to you. However, if you find this annoying, you may connect the grounding connector to an external ground. Under some conditions, connecting an external ground may cause the video image to be disrupted. If you are not sure how to connect the ground, consult a Roland service center. Do not connect this to the following: · Water pipes (may result in shock or electrocution) · Gas pipes (may result in fire or explosion) · Telephone-line ground or lightning rod (may be dangerous in the event of lightning) 14 Checking the inputs and outputs Checking the final output Here's how to check that connections are correct. * Before you proceed, check that your video equipment is connected as described in Connections ( p. 12). 1 Set the video fader to "A." fig.07-01-01.eps 2 Output an image from your video device. Power up the connected video device, and get it to output a video signal. If you're using a video deck or DVD player, press its Play button.

Use this effect when you want to add text you created with your computer or with the P-1 (sold separately). As an example, here's how to superimpose text from image "B" into the background image "A." * The superimpose effect is available only for channel 4. Superimpose Background Superimposing Image 1 2 3 Input a background image into a video input [1]­[3], and input the text image into [4]. Output Set the video fader to "A." Also use Input Select "A" [1]­[3] to select the background image. Press the Superimpose button. The Superimpose button will blink. fig.07-07-1.eps If the Superimpose button is lit, using the input selector to select a channel other than 4 for the superimposed image (A or B) will automatically "suspend" the superimpose effect; the Superimpose button will blink. The input selector buttons blink in one of two ways depending on the function you're using. 4 Use Input Select "B" to select the (text) image that you want to add. Input controller "B" channel 4 will blink rapidly. At the same time, the Superimpose button will light. Blinking slowly When using a transition time knob.The blinking ends after a fixed time. Blinking rapidly When using a compositing effect (P in P or Superimpose).The blinking continues. 5 6 Move the video fader to "B." The superimposed image will appear. Use the superimpose level knob to adjust the range that is cut out. As desired, you can adjust the range of color that will be cut out. fig.07-07-4.eps Easily extracted images As the image to be superimposed, try to use an image that has a clear demarcation between dark and light areas. This will provide the cleanest extraction. If you're using text, choosing white text on a black background will provide the cleanest extraction. * If you want to superimpose image "A" on top of image "B," simply exchange "A" and "B" in the procedure described above. 20
