ATC announces availability of P2 Pro

ATC announced the upcoming availability of the P2 PRO Dual Mono Power Amplifier - a dual mono design delivering 300W of continuous power simultaneously from both channels to drive the most challenging loudspeaker loads with wide bandwidth and ultra-low distortion.

Hand-built by ATC in the UK, The 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.

Within a new low-vibration 19-inch rack-mount chassis design featuring a precision machined 12.7mm brushed aluminium front panel, 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.

ATC Technical Sales Manager, Ben Lilly said, “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.”

Gain matches that of the P2 PRO Dual Mono Power Amplifier’s lower power P1 PRO Dual Mono Power Amplifier sibling so that they can be used together in passive bi-amp or tri-amp systems connected via ‘Link’ phono inputs/outputs.
