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.
-
Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat.
-
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.

-
Only use attachment/accessories specified by the manufactures.
-
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.
-
Unplug this apparatus during lightning storms or when unused for long periods of time.
-
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.

-
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.
-
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. -
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.

4 audio inputs: 3.5 mini jack, Balanced input, TosLink, Bluetooth (optional)
The Normal input accepts an unbalanced input via a 3.5 Mini Jack. 1 Balanced input via a Phoenix style screw terminal plug. Input 3 can be microphone level or line level, set by ( ). The line level can range from -20dBu to 0dBu. The microphone level input can be -40dBu. The minijack can accept mono or stereo inputs. The stereo channels are summed together. This audio is adjusted with potentiometer adjacent by each “Input”.
Priority Override Feature
The Priority input accepts balanced input levels of jumper selected 100 volts audio, 70 volts audio, 25 volts audio and 1volt (approximately line level) audio. Audio on the Priority input suspends audio on the Normal or Auxiliary input and switches the speaker amplifier to pass the Priority audio (A8). After the Priority audio stops, the unit waits a selectable time delay before returning to the Normal or Auxiliary audio input. The delay is computer settable via RS232 from 5 to 60 seconds. With an adapter, the USB connector on a computer can be used to set the delay.
Balanced Line Level Output
A nominal 0dB level, balanced output ( ) is available. The audio output is
post-master fader. The master (Master Volume) fader is on the face per source.
Microphone Wireless Microphone / “Auxiliary Input” A 3.5mm connector is
available to connect an infrared receiver. This receiver picks up an infrared
signal from a special wireless microphone. The wireless microphone is
interrupted by priority audio. There is a level adjustment pot on the circuit
board to balance the microphone audio level against other audio input levels.
Any line level may be input here.
