RCF AM 1122-N Public Address Amplifier
AM 1122-N is a mixer amplifier with 4 mic-line audio inputs expressly designed for paging and background music in all public address audio systems. The nominal power: is a 120 W amplifier. The amplifier output is available either for low impedance loudspeakers (min. 4 Ω) or 100 – 70 V constant voltage line (for loudspeakers having 100 – 70 V transformers).
