Coil Audio CP-448 — 4-Channel Phantom Power Supply

The Coil Audio CP-448 delivers four channels of ultra-clean, regulated 48V phantom power engineered for both modern and vintage condenser microphones. Built on a linear regulated supply with large current reserves, the CP-448 maintains stable, ripple-free voltage across all four channels simultaneously—no compromises under load. A DC blocking circuit isolates phantom from the input transformer, making it safe to use with even the most sensitive vintage mic preamps. Hand-built and tested in the USA, the CP-448 is purpose-built for studios and engineers who refuse to let the power supply be the weak link in the signal chain.
