IMPORTANT SAFETY
INSTRUCTIONS
READ BEFORE OPERATING EQUIPMENT
This product was designed and manufactured to meet strict quality
and safety standards. There are, however, some installation and
operation precautions which you should be particularly aware of.
1. Read Instructions All the safety and operating instructions
should be read before the product is operated.
2. Retain Instructions The safety and operating instructions
should be retained for future reference.
3. Heed Warnings All warnings on the product and in the
operating instructions should be adhered to.
4. Follow Instructions All operating and use instructions should
be followed.
5. Cleaning Unplug this product from the wall outlet before
cleaning. Do not use liquid cleaners or aerosol cleaners. Use a
damp cloth for cleaning.
6. Attachments Do not use attachments not recommended by the
product manufacturer as they may cause hazards.
7. Water and Moisture Do not use this product near water-for
example, near a bath tub, wash bowl, kitchen sink, or laundry
tub, in a wet basement, or near a swimming pool, and the like.
8. Accessories Do not place this product on an unstable cart,
stand, tripod, bracket, or table. The product may fall, causing
serious injury to a child or adult, and serious damage to the
product. Use only with a cart, stand, tripod, bracket, or table
recommended by the manufacturer, or sold with the product.
Any mounting of the product should follow the manufacturers
instructions, and should use a mounting accessory
recommended by the manufacturer.
9. A product and cart combination should be moved with care.
Quick stops, excessive force, and uneven surfaces may cause
the product and cart combination to overturn.
10. Ventilation Slots and openings in the cabinet are provided for
ventilation and to ensure reliable operation of the product and to
protect it from overheating, and these openings must not be
blocked or covered. The openings should never be blocked by
placing the product on a bed, sofa, rug, or other similar surface.
This product should not be placed in a built-in installation such
as a bookcase or rack unless proper ventilation is provided or
the manufacturers instructions have been adhered to.
11. Power Sources This product should be operated only from the
type of power source indicated on the marking label. If you are
not sure of the type of power supply to your home, consult your
product dealer or local power company. For products intended
to operate from battery power, or other sources, refer to the
operating instructions.
12. 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 of the third prong are provided
for your safety. If the provided plug does not fit into your outlet,
consult an electrician for replacement of the obsolete outlet.
AC POLARIZED PLUG
13. Power-Cord Protection Power-supply cords should be routed
so that they are not likely to be walked on or pinched by items
placed upon or against them, paying particular attention to cords
at plugs, convenience receptacles, and the point where they exit
from the product.
14. Protective Attachment Plug The product is equipped with an
attachment plug having overload protection. This is a safety
feature. See Instruction Manual for replacement or resetting of
protective device. If replacement of the plug is required, be sure
the service technician has used a replacement plug specified by
the manufacturer that has the same overload protection as the
original plug.
15. Outdoor Antenna Grounding If an outside antenna or cable
system is connected to the product, be sure the antenna or cable
system is grounded so as to provide some protection against
voltage surges and built-up static charges. Article 810 of the
National Electrical Code, ANSI/NFPA 70, provides information
with regard to proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an antenna discharge
unit, size of grounding conductors, location of antenna-
discharge unit, connection to grounding electrodes, and
requirements for the grounding electrode. See Figure 1.
16. Lightning For added protection for this product during a
lightning storm, or when it is left unattended and unused for long
periods of time, unplug it from the wall outlet and disconnect the
antenna or cable system. This will prevent damage to the
product due to lightning and power-line surges.
17. Power Lines An outside antenna system should not be located
in the vicinity of overhead power lines or other electric light or
power circuits, or where it can fall into such power lines or
circuits. When installing an outside antenna system, extreme
care should be taken to keep from touching such power lines or
circuits as contact with them might be fatal.
18. Overloading Do not overload wall outlets, extension cords, or
integral convenience receptacles as this can result in a risk of
fire or electric shock.
19. Object and Liquid Entry Never push objects of any kind into
this product through openings as they may touch dangerous
voltage points or short-out parts that could result in a fire or
electric shock. Never spill liquid of any kind on the product.
20. Servicing Do not attempt to service this product yourself as
opening or removing covers may expose you to dangerous
voltage or other hazards. Refer all servicing to qualified service
personnel.
21. Damage Requiring Service Unplug this product from the wall
outlet and refer servicing to qualified service personnel under
the following conditions:
a. When the power-supply cord or plug is damaged.
b. If liquid has been spilled, or objects have fallen into the product.
c. If the product has been exposed to rain or water.
d. If the product does not operate normally by following the
operating instructions. Adjust only those controls that are
covered by the operating instructions as an improper adjustment
of other controls may result in damage and will often require
extensive work by a qualified technician to restore the product to
its normal operation.
e. If the product has been dropped or damaged in any way, and
f. When the product exhibits a distinct change in performance
this indicates a need for service.
22. Replacement Parts When replacement parts are required, be
sure the service technician has used replacement parts
specified by the manufacturer or have the same characteristics
as the original part. Unauthorized substitutions may result in fire,
electric shock, or other hazards.
23. Safety Check Upon completion of any service or repairs to this
product, ask the service technician to perform safety checks to
determine that the product is in proper operating condition.
24. Wall or Ceiling Mounting The product should be mounted to a
wall or ceiling only as recommended by the manufacturer.
25. Heat The product should be situated away from heat sources
such as radiators, heat registers, stoves, or other products

4. Anschlüsse
Bei diesem Anschluss haben Sie zwei Auswahlmöglichkeiten, nämlich zwischen den unsymmetrischen
Buchsen und den symmetrischen Buchsen, um den SC-7S1 mit dem MA-9S1 zu verbinden.
Komplette Doppelverstärker-
Verdrahtung
Verbessern Sie das Verdrahtungsbeispiel 2, indem Sie einen
weiteren Steuerverstärker SC-7S1 verwendet. Dies ist die so
genannte <komplette Doppelverstärker-Verdrahtung>, bei der das
Mittel-/Hochfrequenzsignal (MF/HF) vom Niederfrequenzsignal
(NF) des Vorverstärkers getrennt wird. In diesem Fall wird die
SC-7S1 als Mono-Verstärker verwendet.
Außerdem erfolgt der Signalausgang an der Ausgangsbuchse
des CD-Players getrennt für den linken/rechten Kanal.
Dadurch wird die Rückstrahlung zwischen dem Mittel-/
Hochfrequenzsignal und dem Niederfrequenzsignal
ausgeschaltet.
Durch den Anschluss mit dem Fernbedienungskabel können
höchstens 6 Geräte synchron bedient werden.
Vorsicht
Wird der Einstellungsmodusschalter auf <Doppelverstärker>
(Bi-Amp) gestellt, können die Kanaleingangsbuchsen B nicht
verwendet werden.
Symmetrische Klemme
q Als symmetrischer Ausgangsstecker dient ein XLR-
Stecker.
w Der für professionellen Einsatz geeignete XLR-Stecker
ist im Geräteinneren in Form eines der folgenden zwei
Systeme verdrahtet.
1. System USA (Stift 2 = TOT, Stift 3 = HEISS
(Spannungsführend))
2. Europäisches System (Stift 2 = HEISS
(Spannungsführend), Stift 3 = TOT)
e Der MA-9S1 benutzt das System USA wie 1 oben.
Wenn ein Vorverstärker oder ein Hauptverstärker, der
das europäische System übernimmt, mit einem Kabel
mit symmetrischen Steckern der Bauart XLR
angeschlossen ist, kann das reproduzierte Signal eine
Phasenumkehrung aufweisen. In diesem Falle muß die
Verdrahtung eines der XLR-Stecker an den Kabelenden
auf das System USA geändert werden. Dies geschieht
durch Vertauschen der Anschlüsse der Stifte 2 und 3.
Dadurch wird es möglich, die Signale mit der richtigen
Phase abzuspielen.
