 MLK high-performance distribution amplifiers are designed for two-way capability 

and the sheltered environment of multiple dwelling units. Model MLKL uses coaxial cable 
power (line 24 Vac to 65 Vac) while Model MLKM uses utility power (mains 220 Vac to 230 Vac, 
50/60 Hz). 

This Installation Sheet provides instructions on how to install the MLK amplifier in a CATV 
system. 

Figure 1 illustrates a closed MLK amplifier:

Unpacking the MLK 

Unpack the MLK amplifier and inspect it for damage. If damage is visible, set it aside in the 
original packing material and contact the Motorola Customer Service Department for further 
instructions. 

Verify that you have received a plastic bag containing: (1) two mounting brackets with two 
machine screws and two sheet-metal screws, (2) a ground lug with solderless connector and 
machine screw.
