DESIGNED TO GUARANTEE RELIABILITY AND HIGH PERFORMANCES.
DESCRIPTION
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.
Front panel LEDs indicate “power on” and the audio signal level.
Fix the amplifier with the included rack ears to the 19” rack front.
Add RCF P/AER-1V front ventilation panels, at least one between each amplifier pair.
