Belden 8412 Balanced Analog 20 AWG Microphone Cable, 250 Feet

Belden 8412 Balanced Analog 20 AWG Microphone Cable, 250 Feet

The Belden 8412 250' 20 AWG Balanced Analog Microphone Cable is rugged bulk cable for studio, live-performance, and professional balanced-audio wiring. This black 250-foot reel uses two high-conductivity tinned-copper conductors, flexible EPDM insulation and jacket materials, and dual braided shielding for dependable microphone and analog audio installations.

Each 20 AWG conductor uses 26 x 34 stranding to maintain flexibility for deployable applications. An 85% tinned-copper braid provides electrical shielding, while an additional 85% Rayon braid and cotton serve reinforce the cable construction. Bare unterminated ends allow integrators, studios, venues, and cable builders to install the connectors required by each application.

Belden specifies a nominal 0.262-inch overall diameter, 600V voltage rating, and operating range from -58 to 194°F. Electrical characteristics include 33 pF/ft conductor-to-conductor capacitance and 10.6 ohms/1000 ft conductor DC resistance. The 8412 is intended for indoor, non-riser and non-plenum use and carries CE, RoHS 2, WEEE, and China RoHS II compliance.

Key Features
