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 66 to let your ears be the judge). On all output
level meters, 0dB indicates full-scale output. Unlike the inputs, hardware clipping
is impossible on the outputs because of the 36-bit resolution built into the mixer
hardware. However, please note that it is possible to mix multiple tracks within your
software application and cause clipping to occur in the output stream before it
reaches the Delta output hardware or monitor mixer.
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 analog and digital input
ports) 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 effect 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. From far left to right, the inputs are labeled "WavOut
1/2," "WavOut 3/4," then "WavOut S/PDIF." 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). Further to the right are more channels, labeled
"H/W In S/PDIF," "H/W In 1/2," and "H/W In 3/4." These mixer inputs are audio
streams from the physical Delta 66 hardware inputs, hence the "H/W" at the front of
each label. 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.
PAN: Each mixer input may be individually panned anywhere in the stereo output
mix. A pan control is positioned directly under each input channel peak meter and
has the appearance of a small vertical pointer. To make a coarse adjustment, click
on the pan control with your mouse and drag it to the desired position. For finer
