P2-PRO - 2x 300 W Dual-Mono Power Amplifier

The P2 Pro Dual Mono Power Amplifier is a dual mono Class A/B design, keeping the power supplies, signal, and return paths discrete. Each channel separatly delivers 300W of continuous power to drive the most challenging loudspeaker loads with wide bandwidth and ultra-low distortion.

The Dual Mono 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.

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’ phonos, proprietary speaker terminals, and a front panel-mounted power switch.
