P500A  500W RMS power amplier
Features
The P500A serves a specic role: to work in conjunction 
with a mixer amplier or preamplier to signicantly 
boost the power in any given commercial installation and 
accommodate large numbers of commercial speakers.  
This amplier utilizes Class D amplier technology 
which means it is extremely lightweight and runs very 
cool despite the high amount of power being sent to the 
speakers. With 500W of power, the P500A can save 
money in large installations by reducing the overall 
number of ampliers used.
