Important Safety Instructions

MAGNETIC FIELD

CAUTION!  Do not locate sensitive high-gain equipment such as 
preamplifi ers or tape decks directly above or below the unit. Because 
this amplifi er has a high power density, it has a strong magnetic fi eld 
which can induce hum into unshielded devices that are located nearby. 
The fi eld is strongest just above and below the unit.

If an equipment rack is used, we recommend locating the amplifi er(s) 
in the bottom of the rack and the preamplifi er or other sensitive equip-
ment at the top.

The lightning bolt triangle is used to alert the user to the risk of 
electric shock.

The exclamation point triangle is used to alert the user to 
important operating or maintenance instructions.
