14 – Troubleshooting
When working with any new piece of equipment like the unit, it’s sometimes difficult to work out with something 
isn’t happening the way you expect. The main thing is to take your time—after all, you’re not paying hourly 
studio rates! Stop and think. Ask yourself questions, like the ones below, and you can usually find the answer.
Also, see the “Messages Lists” section on page 84 for the meaning of messages that may pop up on the display. 
Consult this table when a message appears when an operation cannot be completed by the unit.
Why can’t I hear any sound when I play back?
•  Are the LEVEL knobs of the tracks set to high 
enough?
•  Is the MASTER LEVEL knob set to high 
enough?
•  Have you properly connected the PHONE or 
LINE OUT jack to headphones or an external 
monitoring system (powered monitor speakers 
or an amplifier and speakers)? 
Is the external monitoring system set up 
correctly?
•  Has the VOLUME dial on the back of the unit 
been raised to a suitable level?
Why does the sound I'm recording sound 
distorted?
•  Are the LEVEL knobs of the INPUT A or INPUT 
B on the top panel of the unit set too high? Is 
the input source too loud?
•  Is the monitoring level too high, causing 
distortion from the external monitoring system 
(powered monitor speakers or an amplifier and 
speakers)?
Why can’t I record?
•  When you press the Play (7) button while 
pressing and holding the Record (0) button to 
start recording, is at least one track in recording 
standby (REC indicator lit)?
•  Are inputs assigned to tracks? (See “Assigning 
Why can’t my computer “see” the unit files?
•  Is the unit connected to the computer via 
the USB terminal? (See “Connecting with a 
•  Before making the USB connection, songs, 
tracks, or stereo masters are backed up or 
exported to the FAT partition? 
Files on an MTR partition cannot be directly 
accessed from a computer
When using the AC adaptor, noise occurs if I 
connect a passive guitar or bass directly.
•  Connecting another device to the unit’s LINE 
OUT jack might reduce the noise.
•  This might be caused by interference noise 
from another device. If there is a power 
amplifier or other device that uses a large 
transformer, a fluorescent light or something 
similar nearby, you might be able to reduce the 
noise by changing the distance and orientation 
of this unit in relation to such equipment.
