• Highly Machinable Steel Body: The rugged steel shell arrives in a blank, un-drilled state, providing a uniform and smooth surface layer that can be easily machined, drilled, or hole-punched locally to fit custom potentiometer shafts, inputs, or power arrays.
• Excellent Electrical Isolation: Tightly fitting metal-to-metal panel junctions create a comprehensive Faraday cage, supplying superior RF (Radio Frequency) and EMI shielding to keep delicate preamp audio signals and high-gain matrices completely free of background hum.
