Viking PA-60 - amplifier

This small and lightweight chassis design is possible by utilizing powerful amplifier technology that is less inefficient than other designs competitors use. High efficiency means much less heat dissipation, smaller size, higher reliability, and lower cost. Since each input has its own gain adjustment, one zone can be turned up louder for warehouse paging horn speakers, and the other zone can be turned down for office ceiling speakers. A two-zone paging system can also be helpful for installations in which one group of paging speakers is connected to a source that provides background music, and the other zone provides only paging.
