each of these stereo devices down further to “left” and “right” mono devices. Most
software will handle the outputs as stereo pairs but allow you to pan audio left or
right within the pair. Therefore to send a mono output to OUT1 (for example),
choose WavOut 1/2, then pan that track hard left.
Note that each device name begins with “WavOut.” This is to
remind you that these are software devices, and not always
connected directly to the Delta 44’s output jacks. Instead they are
connected to the Delta 44’s internal patchbay/router and hardware
mixer, and may be sent to one of several destinations. For more
on the patchbay/router, see the Patchbay/Router section of the
Delta Control Panel software discussion.
MACINTOSH SOUND MANAGER INPUTS AND OUTPUTS: The Apple Sound
Manager limits the user to one stereo pair for input and one stereo pair for output.
Within your music software, the device selection when using the Sound Manager
drivers for input and output will be “Sound Manager” both for input source and for
output port.
To select the Sound Manager driver, open the Apple Menu and go to Control Panel
| Sounds. For both “Sound In”and “Sound Out,” click and highlight the Delta icon,
then exit. You may select which Delta hardware stereo input pair and stereo output
pair will be used for the Sound Manager’s Sound In and Sound Out in the Delta
Control Panel “Hardware Settings Page” (see section, “Hardware Settings
Page”under “Delta Control Panel”). Whichever stereo pair you select, the software
input and output device selection within your music program will remain the same.
ASIO DRIVER INPUT DEVICES: When using the ASIO audio drivers with programs
that support ASIO-style audio, the input devices are displayed as mono devices.
Within ASIO software applications, the names of the Delta 44 audio input devices are:
Analog In1 Delta-44
Analog In2 Delta-44
Analog In3 Delta-44
Analog In4 Delta-44
Mon.Mixer L Delta-44
Mon.Mixer R Delta-44
Notice the Monitor Mixer input 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 44’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 send, one would choose “Analog 1/2 Delta-44” for
that track’s output port, and then pan that output hard left. The ASIO outputs are
named as follows:
