Two recent technologies have revolutionized the optimization of sound systems. Unlike older practices where much of
the system's potential is wasted, these new technologies extract maximum performance from all sound system components.
PAaT (Precision Alignment and Tuning) describes optimization of electro-acoustic systems at every stage of implementation,
from design, to installation, to alignment, to mechanical tuning, to electrical tuning. MPC (Multi-Point Commonality) is a
procedure for tuning sound systems that considers the entire listening area and not just a single point. Of all tuning
methods developed, MPC usually yields the best results. It is the most effective way to tune line arrays. Poll Sound is
an active practitioner and advocate of these new technologies.
