The ATC P4, four-way system packs 850W of punch and precision. The ATC P4 monoblock is equiped with active crossovers and three fans to ensure that the amp stays cool at all times. The amplifiers incorporate the same gain reduction and loudspeaker protection circuits as used in the ATC active monitors. This ensures that even working at very high levels the amplifier is held back from clipping so improving the subjective performance and protecting the loudspeakers from damage.
