2—System/MIDI Parameters

Se le c t ing t he Type of Audio t o be P r oc e sse d
The first step in using the DP/Pro is determining the type of audio you’ll be sending into its input
jacks. All DP/Pros can process analog audio. Any DP/Pro with an ENSONIQ DI-Pro digital I/O
board installed can also process incoming digital audio in AES and S/PDIF formats.
System/MIDI Parameter 1: Input
k
Input=Analog Clock=48.000
kHz
Values: Analog; Digital, AES; Digital, S/PDIF; Ana+Dig, AES; Ana+Dig, S/PDIF
Default: Analog
Note: The listed values are available when the optional DI-Pro digital I/O board is installed in
the DP/Pro. When the DI-Pro board is not present, only the Analog setting is visible.
What this Parameter Does:
The Input parameter selects the type of audio source you’ll be sending into the DP/Pro. Rear-panel
combination 1/4”/XLR jacks are provided for analog signals, and the optional DI-Pro digital I/O
board provides digital inputs for AES- and S/PDIF-format data.
Est ablishing the D P /P r o’ s Sam ple Rat e
The DP/Pro’s A/D and D/A converters can operate at several different sample rates.
When an analog signal is being processed, the DP/Pro can operate at either 44.100 kHz or 48.000 kHz.
Both rates have their advantages and disadvantages. The 48.000 kHz provides the highest-quality
signal processing. However, should you be using the DP/Pro’s digital outputs to master an analog
signal to CD or some other digital medium that operates at 44.100 kHz, you’ll need to use the same
sample rate in the DP/Pro.
Note: The DP/Pro’s Sample Rate LEDs—located above the auxiliary display—show the
DP/Pro’s current sample rate.
System/MIDI Parameter 2: Clock
k
Input=Analog Clock=48.000
kHz
Values: 44.100 kHz (when Input=Analog); 48.000 kHz (when Input=Analog)
Default: 48.000 kHz
