Edirol V-4 User Manual

Here’s how to check that the signal from each source device is correctly being input to the V-4, and 
is correctly being output to the TV or projector as final output.

Play back the source device.

Operate the source device (e.g., camcorder, VCR, DVD player, DV-7PR) connected to the V-4 so 
that it will output video.

Check the output monitor.

Power-on the TV monitor or projector that is connected to the output jack of the V-4, and verify that 
the image being output from the V-4 is displayed correctly.

Switching the input channel

Now, try switching the V-4’s input channel. Move the T-bar all the way toward the channel A or 
channel B position. If you moved the T-bar toward channel A, press the left input selector (INPUT 
SELECT). If you moved the T-bar toward channel B, press the right input selector. Successively 
press buttons 1 through 4 to switch inputs. Confirm that the image shown on your TV monitor or 
projector changes accordingly.

Next, you should check whether the image is being correctly output to the preview TV monitor. 

Play back your source device

Operate the source device (e.g., camcorder, VCR, DVD player, DV-7PR) connected to the V-4 so it 
outputs video.

Check the preview output

Turn on the power of the TV monitor that is connected to the preview output jack of the V-4, and 
verify that the image output from the V-4 is displayed correctly.

In the case you do not see output on TV/Projector

• Check that outputs from source devices are correctly connected to inputs of V-4.
• Check that output from V-4 is correctly connected to input of TV or Projector.
• Check that input selection of TV or Projector is set correctly.

When the channel selected has no signal input, a blue image is output to the TV/Projector. You can 
turn On/Off the blue image output by changing the parameter on P.75 or later.
