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
