 12.  Use only with a cart, stand, tripod, bracket, or table specifi ed by the 

manufacturer, or sold with the apparatus. When a cart is used, use 
caution when moving the cart/apparatus combination to avoid injury 
from tip-over.

 13.  Unplug this apparatus during lightning storms or when unused for 

long periods of time.

 14.  Refer all servicing to qualifi ed service personnel. Servicing is required 

when the apparatus has been damaged in any way, such as power-
supply cord or plug is damaged, liquid has been spilled or objects 
have fallen into the apparatus, the apparatus has been exposed to rain 
or moisture, does not operate normally, or has been dropped.

 15. Use the mains plug to disconnect the apparatus from the mains.

 16.  WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO 

NOT EXPOSE THIS APPARATUS TO RAIN OR MOISTURE.

 17.  DO NOT EXPOSE THIS EQUIPMENT TO DRIPPING OR SPLASHING 

AND ENSURE THAT NO OBJECTS FILLED WITH LIQUIDS, SUCH AS 
VASES, ARE PLACED ON THE EQUIPMENT.

 18.  THE MAINS PLUG OF THE POWER SUPPLY CORD SHALL REMAIN 

READILY OPERABLE.

   TO PREVENT ELECTRIC SHOCK DO NOT REMOVE TOP OR BOTTOM 

COVERS. NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO 
QUALIFIED SERVICE PERSONNEL.

   TO COMPLETELY DISCONNECT THIS EQUIPMENT FROM THE 

AC MAINS, DISCONNECT THE POWER SUPPLY CORD PLUG FROM THE 
AC RECEPTACLE. THE MAINS PLUG OF THE POWER SUPPLY CORD

shock.

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

IMPORTANT

XLS Series amplifi ers require Class 2 output wiring.

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 equipment at 
the top.
