Product Description

ATC P2 is a 300W per channel dual-mono power amplifier which delivers full power simultaneously from both channels with minimal crosstalk while keeping the power supplies, signal and return paths discreet.

Perfect Match

Hand built in the UK, the P2 power amplifier uses grounded source class A/B circuit topology, which is the same as used in ATC’s renowned active loudspeakers, designed to complement the operation and aesthetics of their hi-fi preamplifier range. This unique “grounded source” output stage ensures smooth power delivery and extremely low harmonic distortion.

Sound Performance

Developed in tandem with the P2 Pro studio amplifier, the ATC P2 achieves maximum signal separation with minimal crosstalk. Intermodulation between channels via the power supplies is reduced to an absolute minimum across a frequency range of 400kHz. The power delivery from one channel cannot affect the specified power available from the other.

The ultra wide bandwidth results in low distortion and a high dynamic range for tonal accuracy and perfectly timed transients. The no-compromise, high-performance power supply and large heatsinks guarantee outstanding stability and long term reliability. Neutral fidelity ensures excellent product compatibility.

Peak Output

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.


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.

Key Features

- Latest ATC discrete MOSFET output stage
- Grounded source Class A/B topology
- 300W into 8 ohm continuous power O/P capability
- Dual mono-design for minimal crosstalk and interchannel modulation
- Fully separate power supplies for high/low voltage and logic/control
- 400kHz bandwidth to ensure best possible transient reproduction
- Vanishingly low distortion and custom low noise toroidal transformers
- New chassis design for reduced vibration and more striking appearance

Press Reviews

  • 'The P2 is one of those subtle components that quietly works its magic on you, until you suddenly realise that it is doing everything brilliantly but without any fuss or melodrama. Put simply, it just sounds right.' (Hi-Fi News, March 2017)

  • 'In terms of detail, the P2 struck gold once again. Instruments were lifelike and beautifully atmospheric, no matter whether a recording featured a soft solo acoustic ensemble or a grand orchestral bombardment.' (Hi-Fi News, March 2017)

  • 'It maintained an uncanny sense of composure and solidity, right up to quite anti-social listening levels. Don’t think I am implying it’s perhaps a little lacklustre or even pedestrian in its presentation, as this could not be further from the truth.' (Hi-Fi News, March 2017)

  • 'It’s not an amp that aims to impress the listener with a barrage of detail but one that simply allows the music to shine through, irrespective of generation or genre. It boasts a svelte hand with both acoustic intruments and vocals yet manages to keep a firm grip on the most thunderous of bass lines.' (Hi-Fi News, March 2017)
