CPU & DSP MODULES
DSP-600
The DSP-600 is the main audio mixing module in the D-5000 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, AUXIL-
IARY, UTILITY, CUE, and TELEPHONE. These mixes are sent from the
DSP-600 module to the various output modules over the console backplane.
There are no user settings or switches on the DSP-600 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 8-9, for
connection information
The DSP-600 module operates at a factory set sample rate, normally
48KHz, which dictates the output sample rate of the D-5000 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.
D-5000 Serial Interface
Using the Serial Interface
The D-5000 Serial Interface is designed to support serial communica-
tions under the RS-422/485 and -232 protocols. The proper serial interface
protocol must be selected (via DIP switches on the CPU-600 module) or
else serial communications will not function correctly. No serial interface
connections are required for normal, stand alone operation of the D-5000
console; in fact the console will work normally with an improper connec-
tion to the serial interface. The function of the serial interface is to enable
remote operation of the D-5000 console functions; local operation of the
console switches and faders will always override any remote commands
that may have been sent via the serial interface. In addition, the large button
on the CPU-600 module can be used to disable any serial communications
with the D-5000 console. Toggling the switch “ON” and “OFF” alter-
nately enables and disables the serial interface port on the D-5000 console.
The 8-digit display on the CPU-600 module shows “LOCAL” when the
serial interface is disabled, and “REMOTE” when the serial interface is
active. Remember, the D-5000 console can always be controlled by its
faders and switches regardless of the status of the serial interface. If remote
control of the console is desired, the “remote” mode must be selected with
the CPU-600 switch, and the display must read “remote”.
The most common use for the D-5000 Serial Interface is to allow
configuration changes (mutes, tallys, etc.) by means of the “Virtual Dip
