CF900-2400 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 analog topology:
— CF900 — AB class
— CF1200-2400 — H class
The switching power supply minimizes the weight compared with classic transformer power supply.
CF900-2400 amps have built-in crossover with switchable line output. All amps are designed to work on the load 4/8 Ohms and only CF2400-2 can work on the load 2 Ohms.
