ATC announces availability of P2 Pro Dual Mono Power Amplifier
ATC is proud to announce 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 3rd…
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-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. 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.”
Needless to say, 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’ phono outputs, proprietary speaker terminals, and a front panel-mounted power switch. Signing off, Ben 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:
- Max Continuous Output Power : 300W (8Ω, 1% THD).
- Input Sensitivity: 2V rms (ref. 150W out).
- Input Impedance: 10kΩ/leg.
- Frequency Response: <2Hz – >400kHz (-3dB).
- Signal to Noise Ratio : >110dB (DIN).
- Crosstalk: >100dB.
- THD: >0.002%/-95dB.
The British-built P2 Pro Dual Mono Power Amplifier will be available as of November 3, 2016 at a UK RRP of £2,833.00 GBP (plus VAT). For more in-depth information, please visit the dedicated P2 Pro product webpage.
ATC Win at the 2016 What Hi-Fi Awards!
ATC have won awards in three categories at the annual 2016 WHat Hi-Fi Awards.
SCM11 Best standmount speaker £1200-£1500
Awarded 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016.
“It’s hard not to be totally enamoured by the ATC SCM11s. For the money, they seem to do everything right – and their solid curved cabinets look the part too. When it comes to speakers, or even hi-fi kit in general, there are few better ways to spend £1200.”
Learn more on the SCM11 webpage.
SCM19 Best standmount speaker £1500+
“These ATCs are analytical yet never sound clinical or passionless. They remain transparent to the original recording and system electronics. And when it comes to insight and honesty, we haven’t heard any better for the money.”
Learn more on the SCM19 webpage.
C1 system Best speaker package £2000+
“We suppose the highest praise we can offer ATC here is that it has provided a match for our considerably more expensive reference system. We can think of no better alternative for the money. A consummate triumph, to be sure.”

New Product Launch – P2 Power Amplifier
Generating twice the power of its smaller P1 sibling, the P2 will drive the most challenging loudspeakers with ATC’s signature virtues of wide bandwidth and ultra-low distortion…
Hand-built by ATC in the UK, the P2 class A/B stereo power amplifier is designed to complement the brand’s range of hi-fi preamplifiers, both aesthetically and operationally. Rated at 300W continuous power per channel and developed in tandem with the P2 Pro studio amplifier, the ATC P2 is a Dual Mono design, keeping the power supplies, signal and return paths discreet. This approach ensures that the amplifier will achieve the 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 chassis design featuring a precision machined 12.7mm brushed aluminium front panel, the P2’s layout includes a massive, custom-made 400 VA low-noise transformer for each channel and an output stage involving 3 pairs of MOSFET devices per channel to achieve peak current output of over 15 amps. ATC’s unique “grounded source” output stage ensures smooth power delivery and extremely low harmonic distortion. The gain of the P2 matches that of the lower power P1 (150W/ch) so that they can be used together in bi-amp or tri-amp systems, connected via the amplifier ‘Link’ phono inputs/outputs.
The ATC P2 offers balanced XLR and unbalanced phono inputs, ‘link’ phono outputs, proprietary 4mm speaker terminals, and IR remote control.

Soundstage Experience Review the SCM19
North American audio ‘Supersite’ Soundstage! Network has given a glowing review to the SCM19 two-way standmount loudspeaker.
The SCM19 is ATC’s most compact and affordable loudspeaker feauring ‘Super Linear’ (‘SL’) motor technology. ‘Super Linear’ motors use a proprietary iron powder for the area of the motor system closest to the voice coil, reducing the effect of current modulated inductance and, greatly reducing third harmonic distortion. Wether you like to immerse yourself in the technology or prefer to simply focus on the music, reviewer Wes Marshall thoroughly enjoyed the loudspeakers and here is just a taster of what he thought:
“The ATCs did a better job of catching the naturally decaying sounds of instruments in a room than any other speakers I know of.”
“Ever since I bought my first pair of ATC speakers 20 years ago, it’s been my opinion that you can never go wrong with ATC. I nominate Billy Woodman for the Audio Hall of Fame.”
Wes Marshall, Soundstage! Experience, October 2016.
