M-AUDIO Delta RBUS User Manual

Page 18

The Delta R-BUS Audio Card is by nature a multichannel card. You can
see how using only the Sound Manager drivers can be limiting.
Therefore, we recommend the use of a music program that is ASIO
compliant.

ASIO DRIVER INPUT DEVICES

: When using the ASIO audio drivers

with PC or Macintosh music programs that support ASIO-style audio,
the input devices are displayed as mono devices. Within ASIO software
applications, the names of the Delta R-BUS audio input devices are:

R-BUS In1 Delta-R-BUS
R-BUS In2 Delta-R-BUS
R-BUS In3 Delta-R-BUS
R-BUS In4 Delta-R-BUS
R-BUS In5 Delta-R-BUS
R-BUS In6 Delta-R-BUS
R-BUS In7 Delta-R-BUS
R-BUS In8 Delta-R-BUS
SP/ANA In L Delta-R-BUS
SP/ANA In R Delta-R-BUS
Mon. Mixer L Delta-R-BUS
Mon. Mixer R Delta-R-BUS

Notice the SP/ANA In and Monitor Mixer names include "L" and "R"
characters. "L" indicates the left channel of the stereo stream, while "R"
indicates right channel.

ASIO DRIVER OUTPUT DEVICES

: The Delta R-BUS’s ASIO output

devices appear in stereo pairs. Because each device is stereo, you may see
"left" and "right" references within your software application. This allows
the application to pan audio left and right under software control. To
send a signal to a Delta ASIO output 1 (for example) as a mono output ,
one would choose "R-BUS 1/2 Delta-R-BUS" for that track’s output port,
and then pan that output hard left. The ASIO outputs are named as
follows:

R-BUS 1/2 Delta-R-BUS
R-BUS 3/4 Delta-R-BUS
R-BUS 5/6 Delta-R-BUS
R-BUS 7/8 Delta-R-BUS
SP/ANA L/R Delta-R-BUS

WINDOWS MULTIMEDIA SETTINGS

: Windows may be set up to use

the Delta R-BUS as its default audio device, allowing system sounds to be
