Delta Control Panel Installation - for Mac
The Delta Control Panel may be placed anywhere on your hard drive, or any
partition of your hard drive that you find convenient. Once the control panel file
has been dragged from the CD onto your hard drive, you may double click it to
launch the Delta Control Panel software. You may also create an alias to the
control panel by highlighting it, then holding Apple key+M. This alias can then
be placed on your desktop.
NOTE: When using a music software program that is ASIO capable,
launch the Delta Control Panel software from within that program.
Some of the control panel functions will be controlled from within
that program, such as master clock setting and sample rate, so it
is desirable to launch the music program first, and then the Delta
Control Panel from the the program’s “launch” or “control panel”
button. Without the music program open however, it is okay to
open the Delta panel from your desktop or other location.
Delta System Basics
Delta’s Analog Inputs/Outputs
The Delta 410 PCI Audio Card’s analog inputs and outputs are compatible with
a wide variety of audio products. The Delta Control Panel software allows you
to configure the signal level of each analog output individually, or all analog
outputs as a group. Signal level settings of “Consumer” and “-10” are available.
The ‘Consumer’ setting is preferred for semi-pro audio equipment and some
consumer equipment that can accept a ‘hotter’ signal than the ‘-10’ setting. The
‘Consumer’ setting offers approximately 6dB more headroom than does the ‘-10’
setting. Semi-pro and consumer device signal levels vary from manufacturer-to-
manufacturer and even product-to-product, so a little experimentation between
Consumer and –10 settings may be required for optimal results.
NOTE: In order to preserve its high dynamic range and minimize
distortion, the Delta 410 does not have microphone pre-amplifiers
built into it. Therefore direct connection to a microphone is not
recommended. Instead run the microphone signal through a
microphone pre-amp (such as the M-Audio "Audio Buddy™" or
M-Audio “DMP3™”) and then connect the pre-amp output to the
input of the Delta 410.
All analog jacks on the Delta 410 breakout cable are of the RCA (coaxial)
variety. The RCA jacks allow connection to unbalanced (typically semi-pro or
consumer) connections.
