Installation
The MX122 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 MX122 when it is custom installed as outlined 
below. The four feet together with the mounting 
screws should be retained for possible future use if the 
MX122 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 
MX122. Cool operation ensures the longest possible 
operating life for any electronic instrument. Do not 
install the MX122 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.
When the MX122 is placed free-standing on a flat 
surface, allow at least 2 inches (5.08cm) above the 
top and 2 inches (5.08cm) on each side, so airflow is 
not obstructed. Allow 19-1/2 inches (49.53cm) depth 
behind the front panel. Allow 1-7/16 inch (3.66cm) in 
front of the mounting panel for knob clearance.
A custom cabinet installation should provide the 
minimum spacing dimensions for cool operation. Al-
low at least 2 inches (5.08cm) above the top, 2 inches 
(5.08cm) below the bottom and 2 inches (5.08cm) on 
each side, so airflow is not obstructed. The Custom 
Cabinet should be open backed and at least 12 inches 
(30.48cm) away from any surface such as a wall. Be 
sure to cut out a ventilation hole in the mounting shelf 
according to the dimensions in the drawing. Allow 
1-7/16 inch (3.66cm) in front of the mounting panel for 
knob clearance.
