M-AUDIO Delta TDIF - Manual (Page 20)

0dB. On the input level meters, a 0dB condition indicates overload and
audio clipping may occur. Therefore be careful to adjust the incoming audio
levels so that they do not peak in the red section too long (you might use the
monitoring capability of the Delta TDIF to let your ears be the judge). On all
output level meters, 0dB indicates full-scale output. Unlike the inputs,
clipping is impossible on the outputs because of the 36-bit resolution built
into the mixer hardware.
MASTER VOLUME: At the left side of the Monitor Mixer page, you will see
the ‘Master Volume’ faders and peak meters. These faders have the longest
‘throw’ and highest meter resolution of any level controls in the mixer page.
They control the overall stereo level of the mixer output. The peak meters
indicate the output signal levels with respect to full-scale and are directly
affected by the settings of the master volume faders.
MIXER INPUTS: The ‘Mixer Inputs’ are inputs to the monitor mixer. These
inputs accept hardware audio streams (directly from the Delta’s TDIF input
ports and analog or the S/PDIF digital input port) and software audio
streams (digital audio generated in software to be output). This combination
of streams makes the monitor mixer extremely flexible. Each mixer input
channel has its own level fader and may be panned anywhere in the
left/right stereo field. Each input also has its own peak meter. The peak
meters indicate the incoming "pre-fader" levels of the incoming audio, and
are therefore not affected by the fader settings. However, the input faders
do affect the levels of the signals exiting the mixer and you will see the affect
of the input faders on the output "Master Volume" peak meters.
Because of the large number of mixer inputs, not all inputs are displayed
simultaneously. You may use the scroll bar at the bottom of the Delta Control
Panel to scroll the view left or right. On the PC, from far left to right the
inputs are labeled "WavOut 1/2" through "WavOut 7/8," then "WavOut
SP/ANA." These inputs accept the digital audio streams being sent from
your software application (or Windows) to the driver devices with those
same names. Each name begins with "WavOut" to remind you that these are
software streams and may not necessarily be routed to any physical outputs
(see Patchbay/Router Page).
ON THE MAC , These inputs are labeled “SM/ASIO,” as these software
streams will be receiving their digital audio either from the Sound Manager
or the ASIO driver, depending on your selection.
Further to the right are more channels, labeled "H/W In 1/2" through "H/W
In 7/8," and "H/W In SP/ANA." These mixer inputs are audio streams from
the physical Delta TDIF card’s hardware inputs, hence the "H/W" at the
front of each label. These labels are consistent on both the Mac and PC.
