CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK DO NOT REMOVE COVER (OR BACK)  NO USER-SERVICEABLE PARTS INSIDE REFER SERVICING TO QUALIFIED PERSONNEL

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.

AMPBACKPLATE AND TRUMPET SPEAKER WIRING AND INSTALLATION INSTRUCTION

MODEL: AMP04TRP

1. Get the AMPBACKPLATE and remove the knockout of one of the conduit access hole closer to the POWER IN Phoenix connector as shown above. Insert the other end of the power supply wires through the conduit access hole then connect the positive wire to the positive terminal and the negative wire to the negative terminal of the phoenix connector labeled POWER IN on the AMPBACKPLATE.
   

2. Insert the incoming wires from the source CD/DVD player and let it pass through the conduit access hole and connect the wire pair to the green detachable connector. If it’s balanced, attach the inner wire pair to+ and-. Attach the shield to Ground (Sh). Where there is hum. Attach a jumper between – and (Sh). On a CD player with only 2 wires, run hot wire to+ and shield to -. Attach a jumper to (Sh) only if there is hum.
   

3. Get the TRP470 and with the use of a screw driver, remove the two screws (A & B) at the back of trumpet speaker to detach the existing cap of the speaker.

4. After detaching the cap, remove the two screws on the top left (C) and on the bottom right (D) of the backplate.

5. Connect the positive(+) wire from the Phoenix connector to the Black 5 way binding post (COM) of the Trumpet Speaker and the negative wire to the Red binding posts ( 4Q ) of the TRP470. ( For the two and four speaker combination wiring diagram – please see the users manual).
   

6. Position the AMPBACKPLATE to the back of the TRP470 by aligning the two open holes of the AMPBACKPLATE to the two holes vacated by screws C & D in STEP 4. Secure the AMPBACKPLATE to the back of the TRP470 by installing the two provided screws (E & F). Please see the wall, ceiling or pole mounting installation instruction of the TRP470 to complete the installation.

Trouble Shooting Guide

1. No output: Disconnect any secondary speakers and check for operation of the primary speaker only. If still there is no output, check for loose screws on the green input connector. It is easy to think the wires are secure in the connector and one wire is not. Tug on each wire to make sure each is tight.
2. Intermittent output: Check for shorted output causing the amplifier to into and output protection. Check each input wire for loose screws.
3. Distortion: Do not power more than one AMP04TRP on one power supply. While it will work, it will cause distortion.
4. No output, check to see that the power on light is on. It is located on the main PCB. If it is off, the power supply is either bad or has come loose in the power socket.
5. Hum, for single ended inputs, there is a need for a jumper between – and the ground screw. Most of the time, the jumper is needed.
