InstallationInstallationThe C48 can be placed upright on a table or shelf,standing on its four feet. It also can be custom installedin a piece of furniture or cabinet of yourchoice. The four feet may be removed from the bottomof the C48 when it is custom installed as outlined below.The four feet together with the mounting screwsshould be retained for possible future use if the C48is removed from the custom installation and used freestanding. The required panel cutout, ventilation cutoutand unit dimensions are shown.Always provide adequate ventilation for your C48.Cool operation ensures the longest possible operatinglife for any electronic instrument. Do not install theC48 directly above a heat generating component suchas a high powered amplifier. If all the components areinstalled in a single cabinet, a quiet running ventilationfan can be a definite asset in maintaining all thesystem components at the coolest possible operatingtemperature.A custom cabinet installation should provide thefollowing minimum spacing dimensions for cooloperation.Allow at least 2 inches (5.08cm) above the top, 2inches (5.08cm) below the bottom and 1 inch (2.54cm)on each side of the Preamplifier, so that airflow is notobstructed. Allow 20 inches (50.8cm) depth behind thefront panel. Allow 1-7/16 inch (3.66cm) in front of themounting panel for knob clearance. Be sure to cut outa ventilation hole in the mounting shelf according tothe dimensions in the drawing.C48 Front PanelCustom Cabinet CutoutC48 Side Viewin Custom CabinetC48 Bottom ViewCabinet Front PanelCabinetFrontPanelSupportShelf17-3/16"43.66cmCutout Opening for Ventilation9-1/8"23.18cm2-1/4"5.72cmin Custom Cabinet 15"Cutout38.10cmOpeningforVentilation4-7/8"12.38cmCutout Opening for Custom MountingChassisSpacers15"38.10cmNote: Center the cutout Horizontallyon the unit.
