The sound recorded via
the internal mics is not
loud enough
Have you adjusted the input level of the internal mics?
Turn the [MIC] knob to raise the input level of the internal mics.
42
The recorded sound is
noisy or distorted
Is the input level adjusted appropriately?
Noise can tend to be become more noticeable if the sound being input
is at a relatively low level. On the other hand, distortion can crop up
when the level is high. Try to always keep the input level adjusted to a
setting that’s appropriately matched to the volume of the sound you’re
inputting.
If you raise the input level when you’re using the external microphones
with limited sensitivity, any noise from the internal CD drive could
become more noticeable and might be recorded along with your
recording. If you feel dissatisfied with the outcome, try using the
following procedure when recording.
Use batteries to power the unit. (24)
Record to SD memory card. (45, 50, 52)
Use the AC adaptor to power the unit. (22)
Write the song data on the SD memory card to a CD. (95)
Adjust the input level so that the PEAK indicator lights briefly when loud
sounds are input.

Could the input level be raised for a jack to which no device is
connected?
Even if no device is connected, we recommend that you turn down the
input level—turn the knob all the way to the left—for everything other
than the audio source you’re recording.
Could MIC SELECT be set to “Internal
?
Even though you thought you were recording using the external mics,
a noisy recording may indicate that you were actually recording through
the internal mics. If you want to record using the external mics, set to
the “External,” “Ext(MONO),” or “Plug-In Power.”
45
Is the output level set correctly?
If you raise the output level too high, noise or distortion may occur in
the sound from the internal speakers. Turn the [OUTPUT LEVEL] knob to
adjust the volume.
70
Unintended tone quality
Could you have made bass or treble settings?
Set the bass and treble settings to “0.”
72
An unwanted effect is
applied to the sound
Could you have selected a reverb?
Turn the reverb “Off.”
73
Volume changes are not
recorded correctly
according to the actual
performance
Could the [MIC LEVEL] switch be set to the “AUTO” position?
The “AUTO” position is suitable for recording human voices at a
meeting or lecture, and may be unsuitable for recording an instrumental
performance. Change the setting to “MANUAL,” and turn the [MIC]
knob to adjust the input level.
