6.2 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 3 per controller.
Make sure that the controller’s front filter system is clean and dust free (see section 8.2).

Operating voltage
Operating voltage range and frequency are indicated on the controller back panel.
Only connect the controller to an appropriate AC circuit and outlet.
If you are unsure of the output voltage of your AC mains please consult your local electrician.
The following table gives the Power Supply Data for the LA4 amplified controller:
Table 1: LA4 Power supply data
Voltage (V) Mains Frequency (Hz) Current (A) Power Consumption (W)
100 50 - 60 26 1600
120 / 230 50 - 60 22 / 12 1600
6.4 Connecting to AC mains
The amplified controller is supplied either with a European, US, or Japanese AC power connector depending on the
country of use. If the power plug is not appropriate, it can be cut off and wired to a suitable connector in the following
manner:
Table 2: Power cord wiring colour code
Country Live Neutral Earth
Europe Brown Blue Green / Yellow
USA Black White Green
Japan Black White Green
Changing the connector must be done by qualified personnel only.
The specific safety regulations of the country of use must be strictly applied.
The connector 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.
Note: Warranty will not cover damages caused by a wiring error.
