XGW Digital Technology is a China-based custom AC/DC power supply manufacturer specializing in industrial and application-specific power solutions. For audio hardware, the power supply is part of the signal path — rail noise becomes audible noise. We build low-noise multi-output supplies sized to the chassis, not adapted from a catalog brick.
Small-batch, high-expectation builders need a custom PSU for boutique audio equipment that holds up to the marketing claims. We match rail count, footprint and noise budget to the enclosure, with prototypes in 3-7 days and no minimum that kills a launch run.
Consoles, interfaces and outboard gear share the same pain: clean rails across the board. As a studio equipment power supply manufacturer, XGW delivers multi-rail AC/DC with low ripple and controlled EMI so the supply stays out of the recording.
Pedalboards are sensitive to hum and hiss. A low noise power supply for guitar pedals needs tight regulation under mixed digital and analog loads — we isolate the rails and keep switching energy away from the audio band.
Hearing-assist, diagnostic and therapy audio devices add safety and isolation rules on top of the noise spec. For a medical audio device power supply, XGW designs to the required creepage, clearance and leakage limits alongside the low-noise target.
The low-noise multi-output SMPS for a 500-series analog audio chassis walks through a real build: ±16V, ±24V and 48V phantom rails, continuous regulation and universal AC input.
Yes. With proper topology selection, EMI filtering, shielding and output regulation, customized switching power supplies can provide low-noise performance suitable for professional audio applications.
Yes. XGW provides customized AC/DC power supply development, including electrical design, PCB development, prototype testing and mass production support.
