Troubleshooting

If you're having trouble operating MT50, or it doesn't seem to be working
as it should, look up the symptoms in the following table and see what to do.
Symptom
MT50 cannot be powered ON.
Cannot record.
Recordings sound noisy or distorted.
Recordings sound dull, suffer from wow
and flutter, or are of poor quality.
Cannot play.
Recordings playback at the wrong pitch.
Cannot send signal to external effects
processor, or the effects processor does
not correctly apply an effect.
No sound from headphones.
When overdubbing, you can't hear the in-
strument you're playing.
Tape sync does not function correctly.
What to Do
Make sure the AC adaptor is connected to a
suitable AC outlet.
Make sure the AC adaptor is connected to
MT50's DC 12V connector.
Make sure the POWER switch on MT50's
rear panel is set to ON.
If MT50 still cannot be powered ON, please
contact your Yamaha dealer.
Make sure there's a cassette loaded.
Make sure the tape's not wound all the way
to the end.
Make sure that the cassette's record protect
tabs are intact.
Check to see if the REC SELECT switch is
set correctly.
When recording, make sure you set the fader
so that the 0 light is on most of the time and
the +6 light is on occasionally. If the signal
level is too low, the recording may sound
noisy. If it is too high, distortion may occur.
Be sure to use high-quality Type II (High
Bias 70 µ s EQ) chrome cassettes.
Clean the tape head and mechanism. See
"MT50 Maintenance" on page 27.
Try a new cassette.
Make sure the cassette is loaded correctly.
Make sure the tape's not wound all the way
to the end.
Make sure you have not changed the posi-
tion of the PITCH slider since recording.
Turn up the channel's AUX control and
raise the fader. Check the AUX RETURN
level.
Turn up the MONITOR/PHONES control.
Make sure the MONITOR SELECT switch
is set correctly.
Raise the fader for the input module. Make
sure the MONITOR SELECT switch is set
to CUE. Raise the CUE slider.
Make sure the recording level of the FSK
signal is set to about +3dB. Make sure that
you are not using an overly-worn tape.
Check your sequencer's manual for infor-
mation. If you are using a MIDI-to-FSK
converter, make sure it is connected correct-
ly.
