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.

MCRC303 carton includes the following items:  
1. One (1) each MCRC303

Introduction:  
Congratulations on purchasing the Media Center by OWI.  
The OWI MEDIA CENTER is a 50-Watt (25 x 2) High Fidelity Amplifier, Mixer, and  
Room- Combiner all in a small package that fits into a double gang box. This high quality  
durable unit is capable of powering up to 4 speakers per side for voice, music and paging. The  
Media Center has 3 independent inputs that can be used for Line or Mic input.  
The MEDIA CENTER is meant to replace bulky racks, amps, and mixers. OWI made to  
fit into a double gang box where space is limited.  
Assembly Steps:  
Please note that the GANGBOX SHOULD BE cut into the wall and all wires are best to be run  
in the wall.  
Mark the wall were you will be cutting and make sure that nothing is behind the wall before you  
cut. Be sure that nothing is going to disturb the placement of the INWALL AMPLIFIER.  
Please note that this is a digital amplifier. This amplifier is small enough for it to fit into a double  
gang box, and gives off very little heat.  
Important!  
All connections should be made with the power turned OFF!  
Note: Strip all wires 3/16” and place the wires in the connector and tighten screw to the right.  
Note: this must be done for each input.  
1) Disconnect the Green Phoenix connector and connect the wires for your line source/s to the Green  
Phoenix connector. Then Plug this into the MEDIA CENTER to the desired input (1, 2, or 3) be sure that  
the RED jumper is in the Line spot.  
2) Disconnect the Green Phoenix connector and connect all the microphone/s to the MEDIA CENTER to the  
desired input (1, 2, or 3) be sure that the RED jumper is in the Mic spot.  
3) Disconnect the Green Phoenix connector and connect the speaker wires to the SPKR CH1 (Red to +,  
Black to -) phoenix connectors SPKR CH 2(Red to +, Black to -) phoenix connectors. These are both 25  
watts each.  
4) Connect the UL listed 15-Volt transformer (supplied) to input the amplifier. The wires must not be crossed

and will damage the Media Center if this is done. Please note that the power supply must be plugged in to  
a 110-volt outlet.  
5) Finish terminating all the wiring before powering up the MEDIA CENTER.  
6) Turn on amplifier and test system.  
7) Next place the amplifier into the gang box and add the screws to the face screws and add the screws to the  
faceplate and test the system one last time.  
Connecting the Media Centers to another Media Center  
Note: If you are going to do this please note that you will lose one of the inputs on all of the  
additional MEDIA CENTERS.*  
1) Connect a line between the Media Center to the other MEDIA CENTERS with either a 2 conductor wire  
or CAT-5 (only use one pair of the CAT-5 ) Plug them into the desired input (1,2, or 3) be sure that the  
jumper (red plastic) is in the Line spot. Be sure to label the location for the combining location.  
2) Connect the other local equipment in the room (microphone/s or Sources) to the MEDIA CENTER to the  
other desired input (1, 2, or 3) be sure that the jumper (red plastic) is in the correct Mic or line spot.  
3) Connect the speaker wires to the SPKR CH1 phoenix connectors SPKR CH 2.  
* Everything from the first MEDIA CENTER will be heard on all the speakers if the slide  
switch is greater than the off position.  
System is now fully operational.
