RECORDING-SETUP
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).
