Discotheque
Disco systems, such as the one diagrammed in
Figure 75, really test an amplifier's endurance. The
music from a record album may be highly compressed
so that its average power content is high, and the
amplifier may not get even a short rest during many
hours of operation each night.
With its massive heat sinks, and high average
power output capabilities, the P-2200 is an ideal ampli-
fier for disco use. In addition to reliability, the P-2200's
low distortion will produce clean sound, the kind of
sound that avoids listening fatigue - an important
consideration for high sound level operation.
