If Input is set to DIGITAL or OPTICAL:
ext, ext/2, ext/4, ext/8
ext ... The sample is recorded at the input sampling
frequency.
ext/2 ... The sample is recorded at 1/2 the input
sampling frequency.
ext/4 ... The sample is recorded at 1/4 the input
sampling frequency.
ext/8 ... The sample is recorded at 1/8 the input
sampling frequency.
The higher the sampling frequency the higher the
sound quality, but samples recorded at higher fre-
quencies use up correspondingly more memory/disk
space. For most applications the standard 44.1 kHz
sampling frequency is the best choice.
When converting to 22k, 11k, or 5k, the A5000/
A4000 applies a filter to eliminate noise produced by
the conversion. The “LoFi” settings switch the filter
off, resulting in a rougher sound.
If you select a frequency other than 44.1, the quality
that you hear when monitoring the signal may not
match the quality of the actual recording.
For DIGITAL and OPTICAL inputs, the A5000/A4000
supports the following three clock frequencies only:
48kHz, 44.1kHz, and 32kHz. The A5000/A4000 can
not accept input frequencies other than these. Note
also that the A5000/A4000 does not filter out noise
when reducing the frequency to ext/2, ext/4, or ext/8.
Also note that if you reduce the frequency, the quality
that you hear when monitoring the signal may not
match the recording quality.
Note that you can not use the DIGITAL OUT connec-
tor (on the AIEB1 expansion board) to monitor the
input signal. Note also that A5000/A4000’s DIGITAL
OUT frequency is fixed at 44.1kHz.
Knob 5
[ Turn] Pre Trigger
"Pre-trigger" means that recording actually begins the
specified number of milliseconds (a millisecond is 1/
1000th of a second) before recording is started, either
manually or by automatic triggering.
[Range] 0ms — 500ms
This feature ensures that the beginning of samples
won't be cut off. Even if you press the (>START)
knob a little late when recording a sample, an appro-
priate amount of pre-trigger time ensures that you'll
capture the initial attack of the sample. The maxi-
mum setting of 500 milliseconds is actually a half a
second, which should be more than enough for most
applications.
Pre-trigger can also be useful when automatically
triggering recording with a start edge trigger level
setting (TRIGGER functions, page 158). Edge trig-
gering can cut off the initial attack of some sounds,
and an appropriate pre-trigger setting can com-
pletely avoid this problem, allowing the full attack of
the source to be faithfully recorded.
The Pre Trigger parameter is not available if “StOut”
is selected for the Input parameter (Knob 2).
Knob 1
Same function as Cursor q (page 153).
Knob 2
[ Turn] Stereo Level
Sets the recording level when StOut is selected as the
recording source.
[Range] -12 — +12
The parameter can only be edited when StOut is
selected as the input.
Knob 3
[Display] Disk, Volume
When the Record Type is set to Save, the selected disk
and volume are displayed.
The actual disk and volume are selected via the
DISK mode VOLUME parameter (page 172).
