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.
