Menu item Value Function
Input Select
Analog
This selects the type of input that is to be recorded.
Choose this setting if you want to record the analog input. This is the most com-
mon setting. Connect your mic or analog audio device to the combo input jacks.
With this setting, any input from the internal mics or the digital input jack will
be ignored.
Int-Mic Choose this setting if you want to record via the internal mics.
Digital
Choose this setting if you want to record via the digital input. The signal from a
digital device connected to the digital input jack will be recorded. With this set-
ting, any input from the internal mics or the line input jacks will be ignored.
The sampling frequency is specified by the
Rec Freq. setting, and the bit depth
by the Rec Bit setting.
Rec Freq.
44.1 kHz,
48.0 kHz,
96 kHz
This selects the sampling frequency for recording.
Higher sampling frequencies allow higher-quality recording but will produce a
larger project file, meaning that there will be less available recording time on the
hard disk.
The 44.1 kHz setting is sufficient when recording audio that falls within the nor-
mally audible range. This is also the most suitable frequency to use if you’re go-
ing to load the recorded file into your computer and create a music CD from it.
You can use the 48 kHz or 96 kHz settings when recording audio that contains
a significant amount of high-frequency content, from instruments such as cym-
bals, or when you want to capture the brightness and transparency of a natural
environment.
Rec Bit
16 bit,
24 bit
This selects the sample size (bit depth) for recording. A larger sample size allows
the sound to be captured in greater detail but will produce a larger project file,
meaning that there will be less available recording time on the hard disk.
Use the 16-bit setting for normal recording. This allows the broadest compatibil-
ity when loading the recorded file into your computer for playback.
Use the 24-bit setting if you want to capture the tonal character and ambience in
greater detail, such as when recording an instrumental or vocal performance.
