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

Condition: Mint – fully functional, minimal use, home studio environment only.

Description:
The Coil Audio CP-448 is a high-spec, 4-channel linear phantom power supply, purpose-built to provide ultra-clean and safe 48V DC for vintage microphone preamps or any devices that require external phantom power. Featuring a DC blocking circuit to protect input transformers, the CP-448 ensures absolute safety when working with valuable or transformer-coupled gear.

This is not just a generic phantom supply—this is a mastering-grade piece designed with the same philosophy and build quality as Coil Audio’s renowned amplifiers.

Key Features:

• 4-channel regulated linear 48V phantom power
• Large current reservoir – over 75mA total across all 4 channels
• DC blocking circuit – keeps phantom off input transformers
• Slow-ramp 48V DC startup – protects vintage components
• Nichicon and Panasonic high-temp filter caps
• Audiophile-grade Nichicon Muse and Cornell Dubilier film caps in the audio path
• Dale 1% and 0.5% mil-spec resistors throughout
• Neutrik XLR connectors (input/output per channel)
• Steel chassis, hand-built and tested in the USA
• Selectable mains voltage: 120VAC / 240VAC (factory configurable)

Why it's special:
Perfect for engineers using vintage mic preamps that lack internal phantom power—RCA, Langevin, Collins, Telefunken, etc. It delivers noise-free, safe phantom power without compromising the tone or risking transformer damage.
