Unpacking and Placement 

 

The  SM 6  is  packaged  for  maximum  protection.    Please  carefully  read  the 
instructions below before proceeding to unpack the unit.  Be extremely careful. 

Unpacking 

Procedure 

 

Inspect both ends of the cardboard box and open at the end without the 
central staple by slitting the reinforced tape at either side. 

 

Fold back the flaps and tip the package on end and the inner box will 
slide out. 

 

Lay the inner box down flat and upright, open it conventionally by 
separating the top tray from the bottom. 

 

The product can now be removed from the bottom packaging.  This will 
be easier if you have someone to help you by holding the base of the 
box. 

 

Alternately, the bottom tray and preamplifier could be tipped upside 
down and the bottom packaging removed.  If opened in this manner, 
please ensure that you turn the contents over again. 

Note:  Be very careful to secure the unit if you are planning to flip the package 

upside down. 

 

 

Remove the two grey foam protectors off either side of the unit, leaving 
the black material covering. 

 

Pull back the material and remove the protective membrane from the 
front panel. 

The preamplifier is now unpacked and ready for further installation. 

Note:  Please retain all packaging material for future transport.

Placing 

Your SM6 

The  SM 6  should  generally  be  placed  close  to  your  amplifier,  keeping  the 
interconnect cabling short.  Position all the separate components of your system 
close  enough  to  your  SM 6  to  avoid  having  to  stretch  or  extend  any  of  the 
interconnect cables. 

As  a  “rule  of  thumb”,  allow  80-100mm  (3-4  inches)  around  all  sides  of  the 
product and mount the SM 6 on a flat surface, ensuring that the unit has adequate 
access to free flowing air. 

Do not place auxiliary equipment directly on top of the SM 6. 
Do not place the SM 6 directly atop a power amplifier. 

Please do not cover the product with a cloth or similar.
