CF500-700 Power Amplifiers

Analog amplifiers with switching power supply

Park Audio™

CF-series

СF-series is a commercial series of professional power amplifiers.

The amplifiers have class AB topology.
The switching power supply minimizes the weight compared with classic transformer power supply.
CF500-700 amps have various modifications:
— designed to work on the load 4/8 Ohms or only 8 Ohms
— with built-in crossover (with index CR)
