The lightning 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
of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user of the presence of important operating
and maintenance (servicing) instructions in the literature accompanying the appliance.
The apparatus shall not be exposed to dripping or splashing and that no objects filled with liquids, such as vases, shall be
placed on the apparatus.
IMPORTANT SAFETY INSTRUCTIONS
1. Read these instructions - All the safety and operation instructions should be read before this OWI product is operated.
2. Keep these instructions - The safety and operating instructions should be kept for future reference.
3. Heed all warnings - All warnings on this product and in these operating instructions should be followed.
4. Follow all instructions - All operating and other instructions should be followed.
5. Do not use this apparatus near water - for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, near
a swimming pool, swamp or salivating St. Bernard dog, etc.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions. - This OWI product should
be situated so that its location or position does not interfere with its proper ventilation. For example, the Component should not
be situated on a bed, sofa, rug, or similar surface that may block any ventilation openings, or placed in a built-in installation
such as a bookcase or cabinet that may impede the flow of air through ventilation openings.
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 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 wider blade or 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.
10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where
they exit the apparatus.
11. Only use attachment/accessories specified by the manufactures.
12. Use only with the 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 normally, or has been dropped. The user should not attempt to service
this OWI product beyond those means described in this operating manual. All other servicing should be referred to the OWI
Service Department.
15. To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.
16. To prevent electric shock, do not use this polarized plug with an extension cord, receptacle or other outlet unless the blades
can be fully inserted to prevent blade exposure.
17. Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably in susceptibility to
noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a period of
time. The U.S. Government's Occupational Safety and Health Administration (OSHA) has specified the permissible noise
level exposures shown in the following chart.
According to OSHA, any exposure in excess of these permissible limits could result in some hearing loss. To ensure against
potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment
capable of producing high sound pressure levels use hearing protectors while the equipment is in operation. Ear plugs or
protectors in the ear canals or over the ears must be worn when operating the equipment in order to prevent a permanent
hearing loss if exposure is in excess of the limits set forth here.
18. OWI recommends that this apparatus is to be placed on a switched power outlet, one that switches both sides of the line and
has contact separation of at least 3mm.

Introduction:
Congratulations on purchasing the Media Control MC4DNGL by OWI.
A two gang electrical box four channel Audio mixer, the MC4DNGL will allow either Line or Mic level
inputs on each channel. It has an additional four set of level controls to provide a fixed secondary output not
effected by any of the changes on the front panel level input controls. Typical uses of the secondary output
would be “Hard of hearing”, “Room combiner” or priority feed that is not effected by input controls. All
inputs and outputs are balanced so that, if needed, very long input lines and output lines are possible.

Two convenient Mic and Line switches are accessible from the rear allowing Channel 3 or 4 inputs to be
assigned to either Line or Mic level input. Line is to the right and Mic is to the left.
The four inputs are balanced with detachable Euro style three pin connectors. When single ended is
required, - and ground are jumpered together and + is tied to the hot wire.
The Main balanced output is a green Euro Style output connector which is being controlled by a volume
control .
