Crescendo BEAT - The steady pulse of your audio chain.

True linear power supply with two simultaneously active voltage rails.

Key features

• True dual-rail linear power supply: Two fixed outputs that are active simultaneously (15V / 2A and 5V / 3A). No switching or power sharing required.

• Classic linear design: 70 VA toroidal transformer, Schottky rectification, and a total of 17,990 µF filtering capacity - with no high-frequency switching noise (0 Hz switching frequency).

• Two-stage voltage regulation: Each rail is regulated in a cascade. The first stage catches coarse residual ripple and load fluctuations; the second stage minimizes the remaining noise.

• Comprehensive protection: Built-in protection against overcurrent, overvoltage, overheating, and short circuits.

• Passively cooled: Fanless aluminum housing (2.33 kg) for silent operation.

Why linear power matters

A linear power supply operates much more quietly than a switching power supply because it does not chop up the mains voltage at high frequency in the first place. Switching power supplies are ubiquitous because they are cheap to manufacture - not because they are quiet.

A toroidal transformer, precision rectification, generous filtering, and two-stage linear regulation provide power as smooth as a still water surface. This lets your components reveal, without alteration, what’s really in the music.

Two rails. Both continuously powered.

The Crescendo BEAT powers two components in parallel: a 15V output at 2A and a 5V output at 3A - both active simultaneously. Each voltage is fixed rather than variable. A deliberate choice: a rail designed for exactly one voltage delivers it at the highest quality.

Dual-regulated - so interference never gets through

The first stage receives the rectified raw voltage, filters out mains hum and load fluctuations, and passes the cleaned-up rail to the second, exceptionally low-noise stage for the final polish. Both stages reinforce each other’s noise rejection. Noise that makes it through the first stage is stopped by the second.

Classically built—with conviction

A 70 VA toroidal transformer, Schottky rectification, nearly 18,000 µF of filter capacitance, and two-stage linear regulation. No fans, no compromises. The solid aluminum enclosure stays completely silent and cool during operation.

Integrated protection circuits reliably guard against overcurrent, overvoltage, overheating, and short circuits. A voltage selector on the underside lets you switch the mains voltage between 100–127 V and 220–240 V—suitable for use anywhere.

Quiet—and measured honestly

Output noise is at most 10 µVrms with no load and remains at no more than 50 µVrms even under full load—with over 82 dB of noise rejection. We state both figures transparently because that’s how real audio systems work: your devices demand real power, and the BEAT delivers it effortlessly and quietly.
