7 : 1.Welcome

Congratulations on your purchase of the Powersoft 

 

LiteMod 4HC module.

We know you are eager to use the LiteMod module, but 

please take a moment to read this user’s manual and safety 
instructions. In case you have any questions, please do not 
hesitate to contact your dealer or Powersoft.

The LiteMod 4HC is a four channel amplifier modules 

specifically designed to drive high power loudspeakers.

The LiteMod 4HC represents an important evolution 

in power amplifier modules: extremely compact and light-
weight LiteMod 4HC can be easily integrated into any ap-
pliance such as active loudspeakers and stand alone rack 
amplifiers.

The new design of the power supply equipped 

with PFC, reduces power consumption (less than 0.9 
W in standby) while enhancing reliability and consist-
ency in all operating conditions. The high efficiency 
of the output stage improves overall performance 
delivering pristine power and clean output signal. 

 

A dedicated optional DSP board can be easily plugged to 
the module providing a complete solution in a compact 
package.

Powersoft LiteMod 4HC is the ultimate flexible platform 

suiting your application design.

7 : 2.Unpacking & checking for shipping damage

Your Powersoft product has been completely tested and 

inspected before leaving the factory. Carefully inspect the 
shipping package before opening it, and then immediately 
inspect your new product. If you find any damage notify the 
shipping company immediately.

7 : 3.Disposal of the packing material

The transport and protective packing has been selected 

from materials which are environmentally friendly for dis-
posal and can normally be recycled. 

Rather than just throwing these materials away, please 

ensure they are offered for recycling.
