UP 1121 is a 120 W power amplifier having a single balanced ‘line’ level audio input.
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).
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.
