ATC Loudspeakers P2 PRO Dual Mono Power Amplifier

The ATC P2 Pro Amplifier is true dual-mono power amplifier delivering 300 W per channel with minimal crosstalk.

The P2 PRO Dual Mono Power Amplifier — a really cool looking true dual mono design, delivering 300W of continuous power simultaneously from both channels to drive the most challenging loudspeaker loads. Offering wide bandwidth and ultra-low distortion, the new P2 Pro amplifiers are hand-built by ATC in the UK using a new low-vibration 19-inch rack-mount chassis, with precision machined 12.7mm brushed aluminum front panel.

The new Class A/B P2 PRO Dual Mono Power Amplifier is a dual mono design, keeping the power supplies, signal, and return paths discrete. This approach ensures that the amplifier will achieve maximum signal separation with minimal crosstalk, and that intermodulation between channels via the power supplies is reduced to an absolute minimum across a frequency range of 400kHz. It also means that the power delivery from one channel cannot affect the specified power available from the other.

The P2 PRO Dual Mono Power Amplifier’s layout includes a massive, custom-made 400 VA low-noise transformer for each channel and an output stage involving three pairs of MOSFET devices per channel to achieve peak current output of over 15 amps. According to ATC Technical Sales Manager Ben Lilly, “The final design of these transformers is the result of seven design iterations with the goal of achieving best possible audio performance and lowest possible mechanical noise. This was achieved by using a very high-grade steel core which is then vacuum-impregnated with high-temperature resin, post-winding. The exceptionally low levels of mechanical hum/buzz, along with convention cooling, are vital features if the amplifiers are to be used in control rooms designed with lowest possible levels of background noise.”

About ATC Loudspeakers

ATC was founded in London in 1974 by Australian emigre Bill Woodman, who still heads the company today. An enthusiastic pianist and engineer he was naturally drawn to loudspeaker design and after a period working at Goodmans, where many of the names that went on to found British loudspeaker companies began their careers, he struck out on his own.The premise on which ATC began is a simple one, and one that in many respects is still true today: hi-fi loudspeakers tend to be detailed and accurate but of limited dynamic range, while professional monitor speakers tend to express the opposite character. ATC products were designed from the outset to offer the best of both. It’s an easy concept to describe, but surprisingly difficult to engineer

Through ATC’s commitment to multi-channel mastering and its direct involvement with leading players in the professional audio industry including Sony Music and Telarc, ATC’s products are installed at some of the world’s most prestigious multi-channel studios and auditoria. Where ever the best is required you will find ATC.
