Troubleshooting
If you suspect a malfunction, please check your system once again, taking note of the points listed
below. If it still does not function correctly, contact an Edirol Service Center or the dealer where
you purchased the unit.
Operating the video fader does not switch the image
If the same image is being input to channels A and B, operating the T-bar will not produce any
change in the output image. You must input different images into channels A and B.
Operating the transformer buttons (TRANSFORMER) does not switch the image
With the factory settings, when the memory dial is set to 1, these buttons will “cut” between
images. Check the position of the memory dial.
No image is output even though you play back the source device
Make sure that the output fade dial is set to the center position (green LED lit). With the factory
settings, turning the dial toward the left will fade to black, and turning it toward the right will fade
to white. If the dial is set all the way to left or right, no image will be output. Also make sure that
the input select setting is correct.
Turning the control dial does not change the effect
Not all effects have parameters that can be modified by the control dial. If you have selected an
effect whose parameter can be modified by the control dial, the channel A/B effect button will
blink. If the button is only lit (not blinking), the control dial will not affect the parameter.
Image does not switch (effect not applied) in time with the BPM
Did you press the BPM sync button (BPM SYNC)? The BPM sync button (BPM SYNC) must be
pressed if you want to switch the image or apply an effect in time with the BPM.
Image does not switch (effect does not apply) in time with TAP
Did you press the BPM sync button (BPM SYNC)? The BPM sync button (BPM SYNC) must be
pressed if you want to use the TAP button to switch the image or apply an effect.
Operating the video fader does not switch the image in the expected direction
It is possible that if you detached the video fader to reposition it by 90 degrees, the internal
connector may have been pulled out and re-inserted in the opposite orientation. Detach the video
fader with its mounting plate, and try reinserting the connector in the opposite orientation.
