Items to check
Is the connection cable correctly con-
nected to the TRIGGER INPUT connector?
Are the cables correctly connected to each
pad and pedal?
Are the cables correctly connected to the
TD's OUTPUT jacks or the PHONES jack?
Are the cables correctly connected to the
input jacks of your amp or audio system?
Could there be a problem with the
connection cables?
Could the [VOLUME] knob be turned all
the way to the left?
Have you made the correct input selection
setting on your amp or audio system?
Are the volume settings of your amp or
audio system appropriate?
Check the type of USB flash drive.
Check the format of the USB flash drive.
Does the TD support the sampling
frequency and bit rate of the MP3 file, or
the sampling frequency and bit depth of
the WAV file?
Playback may be unable to keep up if you raise the playback speed or change the pitch
of a high bit-rate MP3.
Is there sufficient free space on the USB
flash drive?
It's not possible to set the "A" and "B" times
any closer than one second.
When using an MP3 file, it might not be possible to play back the A-B repeat region
correctly.
Is the TD correctly connected to your
computer?
Is the USB driver installed?
Make sure that the USB cable connecting
the TD to your computer's USB port is
compatible with USB 2.0 Hi-Speed.
