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

reg isters, stoves, or other apparatus (including ampliﬁers)

that produce heat.

9. Do not defeat the safety purpose of the polarized 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 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,

par ticularly at plugs, convenience receptacles, and the

point where they exit from the apparatus.

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

turer.

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

unused 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 nor mally, 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

SPASHING 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.

Important Safety Instructions

MAGNETIC FIELD

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

ampliﬁers 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 locating the ampliﬁer(s)

in the bottom of the rack and the preampliﬁer 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.

REGARDEZ CES SYMBOLES:

La triangle avec le sigle ‘’foudre’’ est employée pour alerter

l’utilisateur au risque de décharge électrique. Le triangle avec

un point d’exclamation est employée pour alerter l’utilisateur

d’instruction importantes pour lors opérations de mainte nance.

ATENCION CON ESTOS SÍMBOLOS:

El triángulo con el símbolo de rayo eléctrico es usado para

alertar al usuario de el riesgo de un choque eléctrico.

El triángulo con el signo de admiración es usado para alertar

PARA PREVENIR UN CHOQUE ELÉCTRICO, NO RETIRE LAS

CUBIERTAS SUPERIOR O INFERIOR. NO EXISTEN PARTES QUE

PUEDAN SER REPARADAS POR EL USUARIO AL INTE RIOR.

REMITA EL SERVICICO AL PERSONAL TÉCHNICAL CALIFI-

CADO.

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 SHALL REMAIN READILY OPERABLE.
