The exclamation point within an equilateral triangle is intended to alert the user to
the presence of important operating and maintenance (servicing) instructions in
the literature accompanying the appliance.

The lightening flash with arrowhead symbol, within an equilateral triangle, is
intended to alert the user to the presence of uninsulated “dangerous voltage” with­in the product’s enclosure that may be of sufficient magnitude to constitute a risk
o

f electric shock to persons.

b

efore the product is operated.

RETAIN INSTRUCTIONS: The safety and operating instructions should be retained

for future reference.

H

EED WARNINGS: All warnings on the product and in the operating instructions

should be adhered to.

ince they may corrode the cabinet.

ATTACHMENTS: Do not use attachments not recommended by the product manu-

facturer as they may cause hazards.

WATER AND MOISTURE: Do not use this product near water, for example, near a

bathtub, wash bowl, kitchen sink, or laundry tub; in a wet basement; or near a
swimming pool; and the like.

ACCESSORIES: Do not place this product on an unstable cart, stand, tripod, brack-

et, 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 manufacturer’s instructions, and should use a mounting
accessory recommended by the manufacturer.

CART: 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. See Figure A.

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 manufacturer’s instructions have been
adhered to.

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.

LOCATION: The appliance should be installed in a stable location.
NON-USE PERIODS: The power cord of the appliance should be unplugged from the

outlet when left unused for a long period of time.

GROUNDING OR POLARIZATION:

• If this product is equipped with a polarized alternating current line plug (a plug
having one blade wider than the other), it will fit into the outlet only one way. This
is a safety feature. If you are unable to insert the plug fully into the outlet, try
reversing the plug. If the plug should still fail to fit, contact your electrician to
replace your obsolete outlet. Do not defeat the safety purpose of the polarized
plug.

• If this product is equipped with a three-wire grounding type plug, a plug having
a third (grounding) pin, it will only fit into a grounding type power outlet. This is a
safety feature. If you are unable to insert the plug into the outlet, contact your elec­trician to replace your obsolete outlet. Do not defeat the safety purpose of the
grounding type plug.

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.

OUTDOOR ANTENNA GROUNDING: If an outside antenna or cable system is con-

nected 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

r

egard 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 B.

LIGHTNING: For added protection for this product during a lightening 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
t

he product due to lightening and power-line surges.

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
i

nto 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.

O

VERLOADING: Do not overload wall outlets, extension cords, or integral conven-

ience receptacles as this can result in a risk of fire or electric shock.

OBJECT AND LIQUID ENTRY: Never push objects of any kind into this product

t

hrough 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.

S

ERVICING: 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.

DAMAGE REQUIRING SERVICE: Unplug this product from the wall outlet and refer

servicing to qualified service personnel under the following conditions:

• When the power-supply cord or plug is damaged.

• If liquid has been spilled, or objects have fallen into the product.

• If the product has been exposed to rain or water.

• 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.

• If the product has been dropped or damaged in any way.

• When the product exhibits a distinct change in performance, this indicates a
need for service.

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.

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.

WALL OR CEILING MOUNTING: The product should not be mounted to a wall or

ceiling.

CONVERTIBLE PHONO/LINE INPUTS
The MM-1000 has 2 CONVERTIBLE PHONO/LINE (PH/LN) RCA
INPUTS These small switches which are located to the right of the
RCA inputs for channels 2 and 3 allow you to choose between a
PHONO (Turntable) input or a LINE level (Mp3, CD, Tape player

etc..).and require the proper switching.

When switched to the PH position you may use any Turntable with
a magnetic cartridge, remember to connect your ground wire (see
GROUNDING SCREW) or there may be a system hum

And when the switch is in the LN position you may connect any
line level device as described before (Mp3, CD, Tape etc).

NOTE: CONNECTING A LINE LEVEL DEVICE TO A PH INPUT MAY
C

AUSE THAT MIXER CHANNEL TO OVERLOAD AND OR DISTORT.

Now you may plug the RCA’s from your playable medium into each
input to be connected to thier respective CHANNELS (CH).

Then when all of your connections have been made turn on the
mixer by pressing the POWER SWITCH.
