Installation

The MA7900 can be placed upright on a table or

shelf, standing on its four feet. It also can be custom

installed in a piece of furniture or cabinet of your

choice. The four feet may be removed from the bottom

of the MA7900 when it is custom installed as out-

lined below. The four feet together with the mounting

screws should be retained for possible future use if the

MA7900 is removed from the custom installation and

used free standing. The required panel cutout, ventila-

tion cutout and unit dimensions are shown.

Always provide adequate ventilation for your

MA7900. Cool operation ensures the longest possible

operating life for any electronic instrument. Do not

install the MA7900 directly above a heat generating

component such as a high powered amplifier. If all

the components are installed in a single cabinet, a

quiet running ventilation fan can be a definite asset in

maintaining all the system components at the coolest

possible operating temperature.

A custom cabinet installation should provide the

following minimum spacing dimensions for cool

operation.

Allow at least 6 inches (15.24cm) above the top, 2

inches (5.08cm) below the bottom and 2 inches (5.1cm)

on each side of the Integrated Amplifier, so that air-

flow is not obstructed. Allow 20 inches (50.8cm) depth

behind the front panel. Allow 1-7/6 inch (3.66cm) in

front of the mounting panel for knob clearance. Be

sure to cut out a ventilation hole in the mounting shelf

according to the dimensions in the drawing.
