Troubleshooting
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-IIB may
produce interference. To prevent this, turn off the mobile
phone or use it further away from the DJX-IIB.
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.
The display goes blank and all panel controls
are reset.
There is no sound even when the scratch pad
is turned 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 the MIDI bulk data is being transmitted/receiv-
ing or not. When the MIDI bulk data is being transmitted/re-
ceiving, all of the buttons other than the PATTERN STOP
button do not function.
The Pattern does not start even when the
PATTERN PLAYER button is pressed. Check whether the BPM is set to “Sync” or not by pressing the
BPM/TAP button. When set to “Sync”, the external MIDI de-
vice can start the Pattern of the DJX-IIB and the DJX-IIB itself
cannnot start the Pattern.
None of the Scratch Pad sounds or functions
work. Make sure that the DJX-IIB is not set to “external sync” (see
Tip 98). When “external sync” is on, the DJX-IIB Scratch Pad
cannot be used.
The sound is distorted or noisy. • Many of the DJX-IIB sounds have been deliberately pro-
cessed or created with a “lo-rez” or “grunge” sound to suit
certain styles of music.
• Using the CUTOFF and RESONANCE knobs at or near the
maximum settings (especially when the MASTER VOLUME
knob is also at maximum) may result in distortion.
