M-Audio Delta 44 specifications

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:
