As a mono-bridged amplifier: 

 

See Fig. 8.0 for the connection of the power supply and the speaker. Make sure that the impedance of the 
connected speaker is not less than 8 ohms. 
 
 
 

 
 
 
 
 
 
 
 
 
 

 

 

IMPORTANT: 

Always connect the outputs first, before the power supply is switched on. 

 
If the amplifier is to be used as a free-standing unit, it may be attached by means of M4 hexagonal bolts and 
the corresponding slots in the heat sink.
