AM 1125 is a 120W mixer-amplifier with 5 audio inputs. Audio input 1 has phantom power supply and get the priority over the other audio inputs through an external command or automatically thanks to the VOX circuit. Dual RCA connectors can be used to link stereo (unbalanced) sound sources (e.g. CD, MP3 players, tuners, etc.). The amplifier output is available both for low impedance loudspeakers (min. 4 Ohm) or 70/100 V constant voltage lines (for loudspeakers with 70/100 V line transformers). It can also be powered by batteries (24 V dc voltage), in order to ensure its proper operation even when the mains supply is unavailable.
