Pro-Audio & Linear Power Supplies

Ultra-low-noise linear and regulated power supplies for professional studio and audiophile equipment — specification-led OEM and ODM. Targets stay open until the product and performance class are confirmed.

Professional Audio Power

Build the Power Platform Around the Requirement

PaiYi supports specification-led OEM and ODM development of ultra-low-noise power supplies for professional audio. The electrical targets below remain open until the product class and noise budget are confirmed.

Our value-added OEM/ODM approach targets extremely low ripple and noise, tight regulation and premium analog cleanliness — the quiet, brand-defining power behind high-end audio.

ApplicationStudio, stage and audiophile equipment define the noise budget.
Noise BudgetRipple, regulation and transient response are specified around the audio path.
Power and FormOutput rails, chassis format and thermal behavior match the product.
ComplianceSafety and low-EMI requirements reviewed for clean analog operation.

Power Supply Design Priorities

The final architecture should be selected from real product requirements rather than a fixed catalogue assumption.

Input and Output Definition

Confirm input source, required clean output rails, regulation and sequencing.

Noise and Regulation

Define ripple/noise (uV RMS), line/load regulation and transient response.

Topology Choice

Linear vs low-noise switching, transformer and shielding strategy for the audio path.

Efficiency and Thermal Design

Balance low noise with heat, enclosure and convection or passive cooling.

Protection and Safety

Specify isolation, over-current, over-temperature and fault behavior.

Mechanical and Aesthetic

Review chassis finish, connectors, grounding and the premium visual language.

Frequently Asked Questions

Q
Why use linear power supplies for pro-audio?
Linear topology gives very low ripple (under 1 mV rms) and tight regulation (plus or minus 0.1 percent), reducing audible noise in studio and stage gear.
Q
Do you also offer SMPS for audio?
Yes. Where size and weight matter we provide low-noise SMPS (under 50 mV ripple) with audio-grade filtering.
Q
What form factors do you build?
1U to 3U rack, external and embedded options with mechanical and aesthetic customisation.
Q
Can you supply for both studio and live sound?
Yes. Our scope covers studio reference and touring-grade power on an OEM/ODM flow.
