Safety Review 

 

 

 
Certain precautions should be taken when using electrical products. Please observe the safety hints by 
reading the manual and obtaining qualified help if necessary to adhere to the precautions. 
 
 
 

1. 

Always use a properly grounded power supply cord with this product

. Please do 

not defeat the ground pin on the mains plug. This connection provides earth to the chassis and 
signal grounds inside the device for clean and quiet operation. The “Grounding and interface” 
section can help the user/installer clear up a buzz problem if one develops. 

2. 

Avoid high temperature operation in equipment racks by providing air 

circulation

. The number one killer of electronic gear is HEAT. Vented rack panels may look like 

wasted space to an interior decorator, but they look like 

beauty

 to a technician or equipment 

designer! If the front panel is hot, it is roasting inside the box. 

3. 

Avoid areas of high magnetic fields

. The steel chassis of 

S&M

 is designed to shield 

the circuits from EMI and RFI (magnetic and radio interference). When installing equipment in 
racks, it is prudent to put power amplifiers and large power supplies at least several rack spaces, if 
not in a different rack, away from equipment that deals with low level signals. Separation of high 
level and low level equipment can pre-empt trouble caused by heat and EMI. 

4. 

Care should be taken to avoid liquid spills around equipment

. If a spill occurs, 

please shut off the gear and disconnect the mains. A qualified technician should investigate 
accidents to prevent further equipment damage or personnel hazards caused by spills. 

5. 

If one is uncomfortable with opening gear and changing jumpers or making 

adjustments, please seek qualified help if necessary.

 

6. 

If adjustments or jumper changes are required, please disconnect the mains plug 

before opening the top

. Dropped screws or tools on a live circuit board can manifest themselves 

as burn marks and smoked components. While we feel your pain, (been there) subsequent damage 
is not covered by the warranty.
