ATC Announces P2 PRO Dual Mono Power Amplifier

ATC announces the upcoming availability of the P2 PRO dual mono power amplifier, rated to deliver 300 watts of continuous power.

Hand-built by ATC in the UK, the Class A/B P2 PRO is a dual mono design, keeping the power supplies, signal, and return paths discrete.

This approach helps ensure that the amplifier will achieve maximum signal separation with minimal crosstalk, and that intermodulation between channels via the power supplies is reduced to a minimum. 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 and a precision machined 12.7 mm brushed aluminium front panel, the P2 PRO’s layout includes a 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.”

Gain matches that of the P2 PRO’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.

The P2 PRO offers both balanced XLR and unbalanced phono inputs, “Link” phonos, proprietary loudspeaker terminals, and a front panel-mounted power switch.

Lilly adds, “The mains power ‘soft-start’ feature has been revised, slowing the rate at which the unit powers up. The design of the venting has also been revised with the steel mesh covering the heatsink vents being replaced by a beautiful acid-etched stainless steel insert. Not only does this component greatly enhance the amplifier visually, it also reduces lid/cover vibration.”

The P2 PRO comes with ATC’s six-year warranty and will be available as of November 3, 2016 at a UK RRP of £2,833.00 GBP (plus VAT).
