The LED’s on the front panel (next to the “TAKE” switch) indicate
security levels:
“GST” (GUEST) - allows operation of controls, but not recalling of
presets. (Default code is any non USR or ADM three digit code).
“USR” (USER) - allows operation of controls and calling up presets, but
not recording any changes. (Default code is 123).
“ADM” (ADMINISTRATOR) - allows operation of controls, calling up
presets, modifying and saving presets. (Default code is 777).
3. The third additional function is to select and store console presets.
PLAYBACK PRESETS
On power up, the last preset number taken is displayed in the CPU
window. Presets have fixed, non-editable names “PRESET01”-“PRESET99”.
You can view and playback other preset names by rotating the PRESET
SELECT knob. If you stop at a preset, the display will indicate that preset
name for 4 seconds, then revert to normal. If you press the TAKE button
while a preset is showing, you will playback that preset. Each preset is stored
in the console’s memory.
RECORDING PRESETS
Holding down the TAKE button for over 1 second will record all current
control surface settings into the current preset number (assuming the security
access allows it). You must rotate the PRESET SELECT knob to the desired
number before pressing TAKE. Recorded settings include all input module
switches, fader levels, EQ panel switches and levels.
In the event that the console is powered down, upon the next power up
the console will assume the settings of the preset that was current before the
power was removed.
DSP-8
The DSP-8 is the main audio mixing module in the D-8000 Digital Audio
Console. It functions solely as a mix engine, combining all of the console
audio signals as directed by the console faders and switches to produce the
various output mixes for PROGRAM, AUDITION, AUXILIARY,
UTILITY, SEND, CUE, and TELEPHONE. These mixes are sent from the
DSP-8 module to the various output modules over the console backplane.
There are no user settings or switches on the DSP-8 module; however the
external AES clock sync and slave connections appear on the upper DB-25
connector on this module. See the hook-ups section, page 8-11, for connec-
tion information.
The DSP-8 module operates at a factory set sample rate, normally 48kHz,
which dictates the output sample rate of the D-8000 console digital outputs.
Consult Wheatstone Tech Support if you wish to use a different output
sample rate. Since all of the console digital inputs are equipped with sample
rate converters, the console inputs will accept any sample rate between the
range of 1/2 to twice the output sample rate, and will actually track a variable
sample rate as long as it remains within this range. This feature allows you
to interface different types of digital sources into the console, each with
different sample rates.
Note: Superphone
module fader and
switch settings are not
recorded.
