ATC Announces Availability of P2 PRO Dual Mono Power AmplifierSpecialist British loudspeaker drive unit and complete sound reproduction system manufacturer ATC announces the upcoming availability of the P2 PRO dual mono power amplifier -- a true dual mono design, delivering 300W of continuous power simultaneously from both channels to drive the most challenging loudspeaker loads with ATC's signature virtues of wide bandwidth and ultra-low distortion -- as of November 3. Hand-built by ATC in the UK, as implied by name, 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" rack-mount chassis design featuring a precision machined 12.7mm brushed aluminum front panel, the P2 PRO dual mono power amplifier's layout includes a massive, custom-made 400VA 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 15A. 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." The company says, with ATC's unique "grounded-source" output stage, smooth power delivery and extremely low harmonic distortion is a given. 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. The P2 PRO dual mono power amplifier offers both balanced XLR and unbalanced phono inputs, link phonos, proprietary speaker terminals, and a front panel-mounted power switch. Signing off, Lilly lets it be known that this product has been a long time in the making due to two major factors -- namely, new power supply design and a new top cover/lid design: "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." Weighing in at an impressive 21kg/46.2lbs, the P2 PRO dual mono power amplifier's accomplished specifications similarly leave little to chance with a quoted 300W (8ohms, 1-percent THD) maximum continuous output power rating; 2V rms (ref. 150W out) input sensitivity; 10 kiloohm/leg input impedance; <2Hz - >400kHz (-3dB) frequency response; >100dB crosstalk; and >0.002-percent/-95dB THD. The P2 PRO dual mono power amplifier reassuring comes complete with ATC's attractive six-year warranty, which helps make for a high- value, long-term investment for any user looking to upgrade their pro audio amplification system. The British-built P2 PRO dual mono power amplifier will be available as of November 3, 2016.
