M-AUDIO Delta 410 - Manual (Page 15)

WINDOWS MME AUDIO OUTPUT DEVICES: All Delta 410 analog and
S/PDIF outputs may be used simultaneously for a total of 10 output channels.
Within your software application(s), the names of the Delta 410 audio output
devices are:
WavOut 1/2 Delta-410
WavOut 3/4 Delta-410
WavOut 5/6 Delta-410
WavOut 7/8 Delta-410
WavOut S/PDIF Delta-410
All WavOut devices allow playing a stereo audio stream to the analog hardware
outputs (for WavOut 1/2, 3/4, 5/6, 7/8), the S/PDIF hardware output (for WavOut
S/PDIF), and/or into the hardware router or mixer. Your application software may
break each of these stereo devices down further to "left" and "right" mono devices.
Therefore you may see them as "Left WavOut 1/2 Delta-410, Right WavOut 1/2
Delta-410", or "Left WavOut S/PDIF Delta-410, Right WavOut S/PDIF
Delta-410", etc. from within your music software. Other software will handle the
outputs as stereo pairs, but allow you to pan audio left or right within the pair.
Note that each device name begins with "WavOut." This is to remind you that
these are software devices, and not always connected directly to output
hardware. Instead they are connected to the Delta 410’s internal patchbay/router
and may be sent to one of many destinations. For more on the patchbay/router,
see the Patchbay/Router section of the Delta Control Panel software discussion.
ASIO or EASI DRIVER INPUT DEVICES: When using the ASIO or the EASI
audio drivers with music programs that support this type of audio, the input
devices are displayed as mono devices. Within these software applications, the
names of the Delta 410 audio input devices are:
Analog In1 Delta-410
Analog In2 Delta-410
S/PDIF In L Delta-410
S/PDIF In R Delta-410
Mon. Mixer L Delta-410
Mon. Mixer R Delta-410
Notice the S/PDIF 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 or EASI DRIVER OUTPUT DEVICES: The Delta 410’s ASIO and EASI
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
