Digital Delay/EQ
2 In x 6 Out
Equalizers for each zone, as well as digital delays, provide
frequency and time adjustment to compensate for the vari-
ous sub-systems if they are geometrically out of plane. For
example, flown array and ground-stacked subs.
CAUTION: This example is not meant to
be used as a template for your own system
designs. Acoustical characteristics, physical con-
straints, audio content, audience, and other relevant
factors should always be uniquely weighed into your
own applications on a per-project basis.
LD-3 Compensating Line Driver
In addition to its unique atmospheric correction for high
frequencies and low-frequency compensation capabili-
ties, Meyer Sound's LD-3 air attenuation compensating
line driver (Figure 5.3) can be used effectively to integrate
subwoofers in a design with MILO/MILO 120 arrays.
