Performance 2 Monoblock Amplifier

The Performance 2 Monoblock Amplifier is stunning achievement, producing 1,200watts into 8 ohms and 2,000 watts into 4 ohms, sufficient to drive virtually anyloudspeaker made, regardless of impedance or size

A New Reference

The Constellation Performance 2 Stereo and Monoblock Amplifiers are among the very finest amplifiers ever built, engineered to deliver an unmatched combination of sound quality and unbridled power.

The Input Stage

The Line Stage Gain Module input stage utilizes hand-matched, low-noise transistors combined with a servo circuit that corrects any signal balance inconsistencies. The Constellation Direct XLR input removes one amplification stage from the signal path for less complexity and even greater musicality with these Performance 2 flagships.

The Power Supply

Performance 2 elevates sound to a new level with our revolutionary Switch-Mode Power Supply (SMPS), the best amplifier power supply ever created. Power Factor Correction (PFC) technology provides stable power at any AC supply voltage—worldwide. Voltage and current are always in phase regardless of speaker load, power over the previous version is increased by 20 percent, and noise is more than 20 dB lower than a typical linear power supply.

The Circuit

The Performance 2 amplifiers employ balanced configuration, using separate amplifier circuits for the positive and negative halves of the audio signal. Other balanced amplifiers use N-type transistors for the positive half of the circuit and P-type transistors for the negative half. Our Balanced Bridged configuration uses only N-type transistors, so both signal halves pass through exactly the same circuitry—with even the softest musical details preserved.

The Performance Pinnacle

The Performance 2 amplifiers further refine the proven circuits and core design philosophy that are the Constellation design ethos. Through a combination of Constellation’s innovative audio circuits and revolutionary SMPS power supply, the Performance 2 amplifiers achieve truly astounding sonic results, eclipsing that of their predecessors and even the outgoing Reference series. Music lovers seeking an unrivaled listening experience will be amply rewarded.

Performance 2 Preamplifier

The Ultimate Line Stage

The Constellation Performance 2 Preamplifier delivers an unmatched combination of sound quality, user-friendliness and flexibility. Its performance is elevated to even higher levels with a separate, physically isolated power supply featuring our proprietary Switch Mode Power Supply incorporating core technologies that achieve their fullest potential in the elite Performance 2 series.

Classic Circuitry

Constellation’s Line Stage Gain Module employs fully balanced, mirror-imaged circuits with hand-matched, ultra-low-noise transistors. A unique servo circuit monitors the signal balance and corrects for any inaccuracies. When used with a Constellation amplifier, it can feed the preamplifier output to the amplifier’s Constellation Direct XLR input, thus bypassing the amplifier’s input stage for sound that is even more pure and refined.

SMPS Power Supply

Constellation engineers spent years refining the application of Switch-Mode Power Supply technology, knowing that despite the engineering challenges, SMPS would deliver far better results than those achieved by transformer-based linear power supplies. The result is DC voltage more than 20 dB quieter, with the same predictably excellent results regardless of AC wall voltage. The power supply is further isolated from the sensitive preamplifier circuits by placing it in a separate aluminum enclosure, thick enough to block all interference.

True Dual Mono

The mirrored circuit layout positions the left channel precisely opposite the right channel. Inputs and outputs are entirely separated, with the left-channel inputs and outputs on one side of the rear panel and the right-channel inputs and outputs on the other. Many dual-mono preamplifiers recombine the channels at the inputs and outputs, negating the benefits of this elegant design.

A New Reference

The Performance 2 Preamplifier incorporates the most evolved technology, circuits, meticulous design and musicality of any Constellation preamplifier. Paired with the Performance 2 Stereo or Monoblock Amplifiers, it becomes the nucleus of the most sophisticated and satisfying audio system.
