Yamaha P-2200 - Manual (Page 47)

Concert Sound
Figure 73 illustrates the P-2200 in a typical setup for
concert reinforcement. Note that there are a number of
completely separate feeds, with separate limiters,
equalizers, electronic crossovers, and power amplifiers.
The P-2200's peak reading meters are a special
advantage in concert sound systems. They indicate the
amount of headroom left in the system, and help the
operator avoid clipping distortion, and possible speaker
system damage. Individual parts of the system can be
easily checked during setup, by turning down the cali-
brated attenuators on all other parts of the system. When
check out is finished, it's easy to bring back the levels
to previous settings.
Due to its high power output capability, the P-2200
is less likely to damage speaker systems as a result of
peak clipping. At the same time, the P-2200's AC
coupled input will not pass dangerous DC signals,
further protecting speakers.
Besides having exceptional specifications, the P-2200
is extremely reliable, and is built to take the abuses of
the road. Bracing the rear of the P-2200 in a portable
rack will "ruggedize" it for the most extreme cartage
requirements. In addition, the P-2200's protection
circuits smoothly limit power during severe thermal
and power demands (see Page SIX 13).
