4.4 COMPLEMENTARY FILL
For large-scale applications, typically where V-DOSC is used as the main L/R FOH system, ARCS can
be used for center-fill (flown or stacked), stereo front-fill, offstage fill or delay system applications. The
number of potential uses for ARCS as a fill enclosure is only limited by your imagination. The following
recommendations give some commonly used examples. In all cases, proper time alignment of fill
systems with respect to the main L/R FOH system is essential for obtaining optimum results. Similarly,
pre-delay to time align the overall sound reinforcement system (main L/R plus fill systems) with the
energy generated on stage is also an important consideration, particularly for the first 10 rows of the
audience. SMAART, SPECTRAFOO or WINMLS are cost-effective measurement tools for performing
time alignment that are recommended for this purpose.
