P1-PRO - 2x 150 W Dual-Mono Power Amplifier
The P1 Pro is a MOSFET Class A/B design dual mono power amplifiers with 150 W per channel into 8 Ohms. At 150 W per channel into 8 Ohms, this fan-less, rack-mountable power amplifier offers the perfect solution for any studio wishing to get the best out of their passive monitors.
The P1 Pro features a 19-inch rack-mount chassis with front panel mounted standby button and L/R clip indication. The amplifiers incorporate the same gain reduction and loudspeaker protection circuits that are used in the ATC active monitors. These circuits ensure that the amplifier will not clip, even when working at very high volumes, which protects the loudspeakers from damage and improves the subjective performance of the entire system. Importantly, neither amplifier uses a fan, so they can be placed anywhere, including the control room.
The P1 Pro is a ‘true’ dual mono design: the power supplies, signal, and return paths are totally separated from each other. This approach maximizes signal separation and minimizes crosstalk. Further, intermodulation between channels via the power supplies is reduced to an absolute minimum at all frequencies, and the power demand from one channel cannot affect the specified power available to the other channel.
