The Bel Canto e.One VBS1 (Virtual Battery Supply) is an external, low-noise power supply engineered to deliver clean, isolated DC power to up to three Bel Canto VBS-compatible front-end components. By replacing standard internal power configurations with a centralised, quiet DC foundation, the VBS1 isolates sensitive digital and analogue audio circuitry from mains noise, voltage ripples, and power line pollution.

Constructed within a heavy-gauge, anti-resonant steel chassis, the VBS1 utilises a multi-stage isolation and filtration architecture. Its initial pre-filtration stage combines low-noise rectification with high-energy storage, shifting high-frequency switching energy well beyond the audible band. The output stage features a massive LC filter bank alongside polypropylene capacitors, achieving over 100 dB of noise isolation starting below 100 Hz. This reduction in low- and mid-frequency noise preserves micro-dynamics, subtle tonal timbres, and low-end authority.

KEY FEATURES & PROPRIETARY TECHNOLOGIES

• Virtual Battery Supply (VBS) Architecture: Combines low-noise switching technology with multi-stage isolation to deliver ultra-stable DC power comparable to pure battery performance.
• Multi-Stage LC & Polypropylene Output Filtering: High-capacity LC filter banks combined with polypropylene capacitors deliver over 100 dB of noise isolation from below 100 Hz, suppressing power line pollution.
• Multi-Component Power Hub: Single external power unit capable of simultaneously running up to three Bel Canto VBS-designated audio components.
• Out-of-Band Switching Spectrum: Restructures power to high-frequency energy operating well outside the audible audio spectrum to prevent noise contamination.
• Heavy-Gauge Steel Chassis: Heavyweight, all-steel enclosure provides electromagnetic shielding and physical damping against mechanical resonances.
