ATC P2 power amplifier


Generating twice the power of its smaller P1 sibling, the P2 will drive the most challenging loudspeakers. Hand-built by ATC in the UK, the P2 class A/B stereo power amplifier is rated at 300 Watts continuous power per channel and was 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 three pairs of MOSFET transistors per channel to achieve peak current output of over 15 amps. ATC’s 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’s ‘Link’ in- and outputs. The ATC P2 offers balanced XLR and unbalanced RCA phono inputs and will retail for £3,125 when it goes on  sale in November.
