The TransAudio Group has announced the release of two new MOSFET Class A/B design dual mono power amplifiers for studio applications from ATC – the P1 Pro and P2 Pro. They’ll be on display at this week’s 137th AES convention in Las Angeles at booth 1014.
The P1 Pro delivers 150 watts per channel and the P2 Pro provides 300 watts per channel, both at 8 Ohms. The 19-inch rack-mount chassis has a 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 help 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.
Neither model uses a fan so they can be placed anywhere, including the control room. Further, they’re 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 a minimum at all frequencies, and the power demand from one channel cannot affect the specified power available to the other channel.
Brad Lunde, president of the TransAudio Group, ATC’s U.S. distributor, states, “ATC is famous for building active studio reference monitors that give engineers a consistent, honest reflection of their work. Although ATC’s revolutionary drivers and chassis get most of the credit for the brand’s legendary transparency, ATC’s superbly-designed amplifiers deserve equal credit.
“Just as the new passive ATC SCM20PSL Pro gives engineers access to ATC’s loudspeaker without the amplification, the new ATC P1 Pro and P2 Pro give engineers access to ATC’s zero-compromise amplification without the loudspeaker itself. Any reference monitor will benefit from the clean power of an ATC P1 Pro or P2 Pro.”
