ATC P1 Dual Mono Power Amplifier

Overview

• The P1 and P2 are high quality power amplifiers designed to partner ATC passive monitors and other loudspeaker systems. The amplifiers incorporate the same gain reduction and loudspeaker protection circuits as used in the ATC active monitors. This ensures that even when working at very high levels the amplifier is held back from clipping, so improving the subjective performance and protecting the loudspeakers from damage.
  Both the P1 and P2 are of a „true“ Dual Mono design, in that the power supplies signal and return paths are totally separated from each other. This approach ensures that the Amplifier will achieve the maximum signal separation and minimum crosstalk. Further, intermodulation between channels via the power supplies is reduced to an absolute minimum at all frequencies, and, the power delivery from one channel cannot affect the specified power available from the other channel.
