RCF UP1121 Power Amplifier

The UP 1121 is a 120W power amplifier having a single balanced ‘line’ level audio input. The amplifier output is available either for low impedance loudspeakers (min. 4 O) or 100 – 70 V constant voltage line (for loudspeakers having 100 – 70V transformers). In addition to the connection to the mains, it can also be powered by batteries (voltage: 24 V dc), in order to ensure its proper operation even when the mains supply is unavailable.

About Power Amplifiers at Sound Productions

Amplifiers do pretty much what they describe—they amplify. In the case of Power Amplifiers (sometimes called audio power amplifiers or power amps), they increase power availability to meet the needs of an electronic source. Power amplifiers increase low-powered audio signals, such as those from microphones, instruments, loudspeakers, or headphones. Choose from a variety of power amplifier models to meet specific wattage or channel configuration requirements for your particular project.

The uses for power amplifiers are highly versatile—they can be beneficial pretty much wherever you have a low-level audio signal that needs a boost. This includes sound reinforcement, live concerts, entertainment and special events, portable PA, home audio (theater, studio, office), or instrumental performances.
