PROBLEM
POSSIBLE CAUSE/SOLUTION
The speakers produce a
“
pop
”
sound when-
ever the power is turned ON or OFF.
This is normal and is no cause for alarm.
When using a mobile phone, noise is pro-
duced.
Using a mobile phone in close proximity to the DJX-II may pro-
duce interference. To prevent this, turn off the mobile phone or
use it further away from the DJX-II.
The volume is reduced or the sound is distort-
ed.
The batteries probably need to be replaced. Either replace all
six batteries, or use an AC power adaptor.
The sound quality has gotten progressively
worse.
Performance Recorder/Sampler
data will not
play back properly.
The display goes blank and all panel controls
are reset.
The selected voice cannnot be played via the
keyboard.
Check whether the DJX-II is set to the Pattern mode (page 10)
or not. When set to the Pattern mode, the keyboard of the
DJX-II does not function as a conventional keyboard.
Not all of the voices seem to sound, or the
sound seems to be cut off.
The DJX-II is polyphonic up to a maximum of 32 notes. If Sam-
ples and Activator phrases are playing simultaneously with a
Pattern, some notes/sounds may be omitted (or
“
stolen
”
) from
one or more of those sections.
There is no sound even when the keyboard is
played or when a Pattern is being played
back.
Check that nothing is connected to the PHONES jack on the
rear panel. When a set of headphones is plugged into this jack,
no sound is output.
The panel buttons do not function.
Check whether MIDI bulk data is being transmitted or re-
ceived.
If a MIDI Bulk Send operation is in process, none of
the panel buttons (with the exception of PATTERN STOP)
function.
