ATC P1 Pro Dual Mono Power Amplifier

The ATC P1 Dual Mono Power Amplifier, a part of the ‘P’ Series, enhances studio setups with top-quality stereo power. With shared circuitry from ATC active monitors, it prevents clipping, guarantees peak performance, and safeguards loudspeakers. Its “true” dual mono design ensures unmatched signal separation and power delivery.

ATC P1 Pro Dual Mono Power Amplifier

Let’s delve into the ATC P1 Pro Dual Mono Power Amplifier: The ‘P’ Series introduces a collection of top-tier stereo power amplifiers meticulously crafted to complement ATC passive monitors and other studio loudspeaker setups. Within this range lie the P1 Pro and P2 Pro models. Both units are housed in identical 3U 19″ rack mount chassis, differing only in their output power capacities.

These amplifiers incorporate the same gain reduction and loudspeaker protection circuits found in ATC’s active monitors. This design choice ensures that even during high-volume operation, the amplifier avoids clipping. This not only enhances the subjective performance but also safeguards the loudspeakers from potential damage.

Each amplifier in the series boasts a “true” dual mono configuration. This means that power supplies, signal paths, and return paths are entirely isolated from each other. This meticulous approach guarantees maximum signal separation and minimal crosstalk. Furthermore, any intermodulation between channels through the power supplies is kept to an absolute minimum across all frequencies. This design ensures that the power delivery of one channel does not impede the specified power available from the other channel, maintaining uncompromised performance.
