MG20XU/MG20/MG16XU/MG16/MG12XU/MG12 Owner’s Manual 35
Appendix
Rack Mounting
The MG12XU/MG12 require at least 10 U* of rack sp ace. To take
into account the cable connections, we recommend to ensure 11
U* of rack space. The MG20XU/MG20/MG16XU/MG16 require
at least 12 U* of rack space. To take into account the cable con-
nections, we recommend to ensure 14 U* of rack space.
* 10 U is approximately 445 mm, 11 U is approximately 489 mm, 12
U is approximately 533 mm, and 14 U is approximately 623 mm.

Precautions for Rack Mounting

This unit is rated for operation at ambient temperatures
ranging from 0 to 40 degrees Celsius. If you install this unit
along with other devices in a poorly ventilated rack, the
ambient temperature inside the rack may rise, resulting in
inefficient performance. Be sure to rack-mount in the fol-
lowing conditions so the unit does not overheat.
• When mounting the unit in a rack with devices such as
power amplifiers that generate a significant amount of
heat, leave more than 1 U of space between the MG and
other equipment. Also, either leave the open spaces
uncovered or install appropriate ventilating panels to
minimize the possibility of heat buildup.
•To ensure sufficient airflow, leave the rear of the rack
open and position it at least 10 centimeters from walls or
other surfaces. If the rear of the rack cannot be left open,
install a commercially available fan or similar ventilating
option to secure sufficient airflow. If you’ve installed a
fan kit, there may be cases in which closing the rear of the
rack will produce a greater cooling effect. Refer to the
rack and/or fan unit manual for details.

Mounting Procedures

(The illustration shows the MG12XU.)
1. Use a screwdriver to loosen the screws on the
sides of the mixer (6 in total).
2. Use the screws removed in Step 1 to install the
rack-mount kit (included with MG20XU/MG20/
MG16XU/MG16, optional RK-MG12 for the
MG12XU/MG12 sold separately) on the mixer.
NOTICE
Be sure to use the screws removed in Step 1. Using other
screws can cause damage.
3. Mount the unit into the rack, and fasten it into
place.
CAUTION
This unit is heavy, and should be lifted by two people
when mounting it into a rack.
* The MG20XU/MG20/MG16XU/MG16 require at least 12 U of rack
space. To take into account the cable connections, we recom-
mend to ensure 14 U of rack space.
