Abstract:
A housing for electronic apparatus, including an enclosure for housing power supply and amplifier circuits that are common to a number of different functional devices. A replaceable, hinged, modular front panel is provided and carries a control circuit on its inner face and switches, indicators, and control knobs on its outer face. Several front panels can be provided having different control circuits for connection with the power and amplifier circuits in the enclosure to thereby change the function of the device or the types of outputs and control functions that it can provide. The front panel is pivotable relative to the enclosure to permit quick and easy access to the interior of the enclosure for inspection and servicing, as well as ready accessibility to the control circuit that is mounted on the control panel. A metallic channel extends from the back panel to the control panel to provide a shielded wireway for input conductors connected with the control circuit.
