• Removable Multi-Panel Framework: The thick aluminium faceplate along with the tough steel top and bottom panels are completely removable. This layout makes bench servicing, internal component populating, board testing, and circuit assembly incredibly straightforward.
• 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, dials, or back-panel power inlets.
• 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.
