5.3.7 Output Path

Starting in the Signal Path window, at the end of the Output processing section, you can access the Output Path window (Figure 5.28) by clicking on its icon (shown above).

In addition to the output of each of the sixteen Input Processing Sections, the eight CobraNet Inputs are fed to the Matrix Mixer, providing a 24 Input by 10 Output fully independent crosspoint mix as controlled by the Input/Output Matrix. Each of the ten Output Processing Sections has independent fader control of all of the inputs to the selected output, i.e. a 24:1 mixer, as shown in Figure 5.29.

The Mix Mode drop-down box is used for selecting exclusive assignments between a particular input and output. This function is repeated with the Single Input Mix Mode Buttons or the routing can be reassigned to the 24:1 mixer.

The selected output channel displays the status of the Output Processing Section objects and their parameters can be accessed by clicking on these icons. There is also a button to quickly access the Input/Output Matrix for further routing options.

Output Processing Sections

Each of the ten Outputs, (two 'Main' and eight 'AUX)', have independent Output Pro- cessing Sections to allow control of the mixed output. Output Processing functions include delay, filters, ambient leveler, limiter, fader, mute, and polarity inverter.

Output Delay

Output Delay (Figure 5.29) can be set for each Output Processing Section. This sig- nal delay is especially useful in loudspeaker array alignment, where the crossovers, mix, and other processing is complete and the loudspeaker needs to be aligned to the system.The inherent delays of the various input signals should be corrected by the delay in the Input Processing Section.

Delay is displayed by IQwic software in milliseconds, feet, and meters. Available delay for each Output Processing Section is up to 2 seconds in 20 microsecond steps (1/4 inch).

Output EQ Filters

These filters are identical to the Input EQ Filters. Please read Section 4.7.4 on Input EQ Filters for more information. As was the case with the Input EQ Filters, the two DSP’s that process the outputs have a finite amount of processing capability. Each of the DSP’s can provide up to 64 filters, with Main 1 and AUX 1-4 processed by one DSP and Main 2 and AUX 5-8 processed by the other. The CPU Utilization meters indicate how much DSP processing capability remains.
