AM 1064 is a 60W mixer-amplifier having 3 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 either for low impedance loudspeakers (min. 4 ?) or 100 - 70 V constant voltage line (for loudspeakers having 100 - 70 V transformers).
