Before recording
Attaching the wind screen (protection against wind and sibilance)
The built-in stereo microphone is highly sensitive. Therefore, a slight breeze or breath
— even a weak air conditioning breeze that hits the microphones directly — will be
recorded as noise. To reduce the level of wind and other environmental noise,
Yamaha recommends that you use the recorder with the wind screen attached to the
microphones. Also, to further minimize the noise level, Yamaha recommends that
you turn on the High Pass Filter via menu item [HPF] (see
page 21 ).
Selecting a Recording mode
The POCKETRAK CX records audio in the MP3 or PCM (WAV) format. As a rule of
thumb, select “PCM 44.1kHz” (better sound quality) for Recording mode to record a
musical performance. Select “MP3 128kbps” (smaller data size) to record musical
practice sessions or conference meetings (see
page 16 ).
Turning the ALC (Auto Level Control) function on or off
Auto Level Control function automatically adjusts the recording level in response to the
input source level to optimize the dynamics of the resulting recording (see
page 17 ).
Setting the microphone sensitivity
You can set the microphone sensitivity level to high or low to accommodate the
input volume. If the volume level is too high, set the [MIC SENS] (microphone sensi-
tivity) switch on the left side of the unit to [LOW]. If the volume level is too low, set
the switch to [HIGH].
Using an external microphone
You can use an external microphone for recording, instead of using the built-in stereo
microphone.
Select [MIC] for menu item [REC SELECT], then connect an external microphone to
the MIC/LINE socket located on the right side of the unit.
Yamaha recommends that you use a microphone with the following specifications as
an external microphone.

Feature
The recording will accurately
represent the original sound and
