22. This product might produce levels of sound able to damage hearing. Pay particular  
       attention and do not work at high or uncomfortable levels of volume for long. In case  
       of troubles or loss of hearing, consult an audiometric specialist. 
 
 

 

Connection to the Means and Absorbtion 

Check that you have power enough for the amplifier (verify the data at the end of this 
manual). The electric mains voltage must be the same as indicated on the panel of the 
amplifier. 
 

Pay attention: 

before making any audio connection remember that it is a goods 

rule to switch off the amplifier (by turning PowerCon connector anticlockwise) 
and to keep the level of the input signal to the minimum, during the switching on. 
  

 

User’s Liability 

 

 

Dangerous Output Tensions 

Amplifiers can generate dangerous output tensions. Do not touch the possible 
uncovered cables of cone loudspeakers while the amplifier is working. 
 

 

Output Connections 
Before connecting an output charge to an amplifier the user stands liable for 
checking that the connection falls into the specifications of this device in order 
not to damage the amplifier and/or the charge. 

 
 
 

Radio Interferences 

A sample of this product was tested and homologated according to the limits of the 
Electromagnetic Compatibility Directive (EMC). These limits have been fixed to give a 
reasonable protection from the dangerous interferences of electric devices. If not installed 
or used according to the present instructions for use, this product might interfere with other 
devices, for instance radio receivers. Otherwise, the possibility of interferences in a 
particular installation is not ruled out in any case. If the product interferes with devices of 
reception and transmission (this condition can be verified by turning the device on and off), 
the user would have to try to eliminate the interference observing one or more of the 
following measures: 
 

  Increasing the distance between the device and the receiver. 

  Connecting the device to a port placed on a circuit different from the one the receiver is connected 

to. 

  Turning or move the aerial of the reception device. 

 

Checking that the concerned unit conforms to the EMC immunity limits (it must have the EC brand). 

All the electric devices sold in EEC must be homologated referring to the immunity from 
electromagnetic fields, high tensions and radio interferences.

 

  Contact qualified personnel.
