The Electro-Voice CPS2.12 Power Amplifier offer a package of reliable high output power, high efficiency and legendary pro audio performance. They are the premium choice as system drive for a variety of Electro-Voice's installation loudspeakers. Their comprehensive protection system includes circuitry against overheating, overload, short circuit, HF and DC as well as back-EMF. A soft start circuit compensates mains inrush current peaks and thus prevents triggering AC mains fuse when switching on the amplifier. Loudspeakers are protected by turn-on-delay relays.
