apparatus (including amplifiers) that produce 
heat.

9)

Do not defeat the safety purpose of the polar-
ized or grounding-type plug. A polarized plug 
has two blades with one wider than the other. 
A grounding-type plug has two blades and a 
third grounding prong. The wide blade or the 
third prong is provided for your safety. If the

receptacles, and the point where they exit from 
the apparatus.

11) Only use attachments/accessories specified 

by the manufacturer.

12) Use only with a cart, stand, tripod, bracket, or 

table specified by the manufacturer, or sold 
with the apparatus. When a cart is used, use 
caution when moving the cart/apparatus com-
bination 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 qualified service person-

nel. 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) WARNING: TO REDUCE THE RISK OF FIRE 

OR ELECTRIC SHOCK, DO NOT EXPOSE 
THIS APPARATUS TO RAIN OR MOISTURE.

16) DO NOT EXPOSE TO DRIPPING OR SPLASH-

ING. DO NOT PLACE OBJECTS FILLED WITH 
LIQUID, SUCH AS VASES,ON THIS APPARA-
TUS.

TO PREVENT ELECTRIC SHOCK DO NOT REMOVE 
TOP OR BOTTOM COVERS. NO USER SERVICE-
ABLE PARTS INSIDE. REFER SERVICING TO 
QUALIFIED SERVICE PERSONNEL.

Important Safety Instructions

FCC COMPLIANCE NOTICE

This device complies with part 15 of the FCC rules. Operation is subject to the following 
two conditions: (1) This device may not cause harmful interference, and (2) this device 
must accept any interference received, including interference that may cause undesired 
operation.

CAUTION: Changes or modifications not expressly approved by the party responsible for 
compliance could void the user’s authority to operate the equipment.

NOTE: This equipment has been tested and found to comply with the limits for a Class B 
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide 
reasonable protection against harmful interference in a residential installation. This 
equipment generates, uses, and can radiate radio frequency energy and, if not installed 
and used in accordance with the instruction manual, may cause harmful interference to 
radio communications. However, there is no guarantee that interference will not occur in a 
particular installation. If this equipment does cause harmful interference to radio or televi-
sion reception, which can be determined by turning the equipment off and on, the user is 
encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the 

receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

IMPORTANT

Xs Series amplifiers require Class 2 output wiring.

MAGNETIC FIELD

CAUTION! Do not locate sensitive high-gain equip-
ment such as preamplifiers or tape decks directly 
above or below the unit. Because this amplifier has 
a high power density, it has a strong magnetic field 
which can induce hum into unshielded devices that 
are located nearby. The field is strongest just above 
and below the unit.

If an equipment rack is used, we recommend locat-
ing the amplifier(s) in the bottom of the rack and the 
preamplifier or other sensitive equipment at the top.
