AMPLIFIED CONTROLLER
User Manual
VERSION 1.2

Cooling

The amplified controller uses a forced air cooling system to maintain a low and even operating temperature. All fan
cooled L-ACOUSTICS ® amplified controllers have front to rear airflow. Therefore when stacking more than one unit in
a rack, mount units directly on top of each other or close any open space in the rack with blank panels.
!
If the controller is rack-mounted do not block front or rear air vents with front or back panels or
doors. If this cannot be achieved a forced ventilation system has to be used.
If the controller is installed in an enclosed rack the open area at the back of the controller must be
at least 140 cm
Ensure that the front filter system is clean and dust free (see section 8.2).

Japan
Changing the plug must be done by qualified personnel only.
The specific safety regulations of the country of use must be strictly applied.
The plug must be approved for the specific voltage and current rating given in Table 1.
The ground connection of the supplied AC power cord is a safety feature. Do not attempt to disable
it by using an adaptor or by other methods.
