Operation Manual

Operation Manual

1.  Read these instructions.
2.  Keep these instructions.
3.  Heed all warnings.
4.  Follow all instructions.
5.  Do not use this apparatus near water.
6.   Clean only with a dry cloth.
7.    Do not block any ventilation openings. Install in accordance 

with the manufacturer’s instructions.

8.    Do not install near any heat sources such as radiators, heat 

registers, stoves, or other apparatus (including amplifiers) 

that produce heat.

9.    Do not defeat the safety purpose of the polarized or ground-

ing-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 provided plug does not fit 

into your outlet, consult an electrician for replacement of the 

obsolete outlet.

10.   Protect the power cord from being walked on or pinched, 

particularly at plugs, convenience receptacles, and the point 

where they exit from the apparatus.

11.  Only use attachments/accessories specified by the manu-

facturer.

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 combination to 

avoid injury from tip-over.

13.  Unplug this apparatus during lightning storms or when un-

used for long periods of time.

14.  Refer all servicing to qualified 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 SERVICE-

ABLE PARTS INSIDE. REFER SERVICING TO QUAL-

IFIED SERVICE PERSONNEL.

TO COMPLETELY DISCONNECT THIS EQUIP-

MENT FROM THE AC MAINS, DISCONNECT THE 

POWER SUPPLY CORD PLUG FROM THE AC RE-

CEPTACLE. THE MAINS PLUG OF THE POWER 

SUPPLY CORD SHALL REMAIN READILY OPERABLE.

WATCH FOR THESE SYMBOLS:

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 in-

structions.

 

IMPORTANT

XLS Series amplifiers require Class 2 output wiring.

MAGNETIC FIELD

CAUTION! Do not locate sensitive high-gain equipment such as 

preamplifiers or tape decks directly above or below the unit. Be-

cause this amplifier has a high power density, it has a strong mag-

netic 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 locating the 

amplifier(s) in the bottom of the rack and the preamplifier or 

other sensitive equipment at the top.

FCC COMPLIANCE NOTICE

This device complies with part 15 of the FCC rules. Operation is sub-

ject 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 equip-

ment 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 ra-

dio or television 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.
