has two "speeds," a bit like gear ratios on a car. In the
normal
(lower) speed range, every preset can run, but
only sampling rates between 32kHz and 50kHz may be used. In the
high
speed range, some presets cannot
run (those which do not have the lightning symbol beside their name on the program screen such as
Smar-
tReverseDelays
), but the whole sampling rate range may be used.
It is recommended that you keep the DSP7000 in the
normal
speed range unless you need to use the higher sampling rates. To
change the
speed
mode, go to the
audio
menu page in the
SETUP
area.
Using the Internal Clock
When you use the “internal” clock, the
system sampling rate
will
correspond with the internal clock’s sampling rate. The
system
sampling rate
is the sampling rate used for all internal processing. If
you’re using the digital inputs while the
system sampling rate
is set to
internal
, you must ensure that the clock of the machine being
input to the DSP7000 is synced to the DSP7000’s digital output. If the machine being input to the DSP7000
is
not
synced to the DSP7000’s output,
dstatus
is likely to read
(slipping)
. That means the two machines
are not in sync and that ugly clicks and pops will be added to the audio. In such a situation you’d be better
off setting
Source
to
external
.

Selecting The Internal Clock’s Rate
To select the internal clock, set the
Source
parameter on the
audio
menu page in the
SETUP
area to
internal
.
Select the internal clock’s rate with the
sample rate
parameter
on the same menu page. Your choices are:
44.1 kHz
The rate of standard compact disks. The
“44.1 kHz sample rate indicator” is illumi-
nated. The highest reproducible audio frequency is ~20kHz.
48 kHz
The “professional” rate
.
The “48 kHz sample rate indicator” is illuminated. The
highest reproducible audio frequency is ~22kHz.
In high speed mode, you can also choose:
88.2 kHz
Twice the rate of standard compact disks. This raises the highest possible reproduci-
ble audio frequency to ~40 kHz. The cost of these “20k +” overtones is a reduction
in the size of the programs the DSP7000 can run. Some programs will be “unload-
able” when
88.2 kHz
is selected.
96 kHz
The new “professional rate” (maybe). This
raises the highest possible reproducible
audio frequency to ~44 kHz. The cost of
these “20k +” overtones is a reduction in
the size of the programs the DSP7000 can
run.
Some programs will be “unloadable” when
96 kHz
is selected.
