Before you begin
27. Video fader (T-bar type)
This is a T-bar type video fader. You can use it to switch between channels A and B, or to adjust the
keying level, etc. According to your preference, you can change the orientation 90 degrees from up
and down to left to right. For details on how to change the orientation, refer to p. 72.
28. Channel B effect buttons (EFFECTS)
These buttons apply effects to the image of video mixer channel B. With the factory settings, the
buttons are assigned (from top to bottom) the Mirror, Chroma Key, Luminance Key, and P in P
(Picture In Picture) effects. You may edit the settings to assign different effects to these buttons if
desired.
29. Channel B effect control dial (CONTROL)
This dial lets you smoothly control a parameter of an effect that is being applied to the image of
channel B. The dial will adjust an effect parameter of the effect button that is blinking.
30. Channel B transformer button (TRANSFORMER) (see p. 23)
This button lets you switch between channels A and B without using the video fader.
About Ground Terminal
In some cases, depending on the environment in which the unit is installed, the surface of the panel
may sometimes feel rough and grainy. This is due to an infinitesimal electrical charge, which is
absolutely harmless. However, if you are concerned about this, connect ground terminal (see
figure) with an external ground. When the unit is grounded, a slight noise may result, depending
on the particulars of your installation. If you are unsure of the connection method, contact nearest
Roland/Edirol Service Center, or authorized Roland/Edirol distributor, as listed on the
“Information” page.
Unsuitable places for connection
• 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)
