During  connecting  and  removing  of  sources  or  amplifiers  to  the 
SAM 20 SE all units of your audio system have to be switched off to 
prevent  damage  of  the  SAM 20 SE  or  any  of  the  other  connected 
units. 

·

 

Please make sure that all cables are in absolute best conditions! 
Broken shields or short-cut cables could damage the SAM 20 SE 
and/or any other connected unit. 

 

4.1  Placement 

 

Important

 

·

 

It is recommended to place the SAM 20 SE into a high quality rack or 
onto a stable table. 

·

 

Do not expose the unit to direct sunlight. 

·

 

Do not cover the ventilation slots. 

·

 

Do not place the SAM 20 SE in close range to heat sources like radia-
tors. 

·

 

Do not place the SAM 20 SE on top of other units, especially not on 
top of power amplifiers, pre amplifiers or similar that produce heat. 
Both units could suffer damage from thermal overload. 

·

 

Do not use the unit in places where it is exposed to vibrations. 

·

 

Do not place the unit close to loudspeakers or into the corner of a room 
where it is exposed to high levels of sonic energy, which might reduce 
the sound quality of the unit. 

 

 

4.2  Mains connection 

The mains input  9 

*

 is on the back panel of the SAM 20 SE. To connect the 

unit to mains use the included mains power cord. If you prefer to use a different 
power cord make sure that it meets the specifications for your home country.
