Description
The new LAIV Audio Crescendo BEAT is a dual-output true linear power supply intended to power two compatible components simultaneously. It provides a 15V/2A rail and a 5V/3A rail, allowing it to replace two separate power adapters.
The 15V output is intended for products including the Crescendo VERSE and Harmony µDAC, while the 5V output can be used with streamers and the Harmony µDDC. It can also be used with other compatible 5V or 15V equipment. Two DC cables are included, and the fanless aluminium chassis is available in black or silver. Protection circuitry and a mains selector are also included.
The Crescendo BEAT features a 70VA toroidal transformer, Schottky rectification, nearly 18,000uF of filter capacitance, and two-stage linear regulation on each rail. The first stage absorbs mains ripple and load swings, then hands an already-clean rail to a low-noise second stage for the fine polishing. Each stage multiplies the other's rejection, which is how the BEAT holds output noise at or below 10uVrms with no load and at or below 50uVrms at full load, with ripple rejection above 82dB.
Two 50cm DC cables are in the box, and the BEAT is just as happy with non-LAiV components that accept 5V or 15V DC. Over-current, over-voltage, over-temperature, and short-circuit protection are all built in, and a selector on the underside switches the mains between 100-127V and 220-240V
DC Cables:
YELLOW connector is for 15V (DC 5.5mm 2.5mm) - Harmony µDAC or VERSE
BLACK connector is for 5V (DC 5.5mm 2.1mm) - Harmony µDDC
