Oval Window Audio The Satellite III

The Satellite III is Oval Window Audio's most popular induction loop system for large facilities such as houses of worship and auditoriums.

Compatible with all telecoil-equipped hearing aids and cochlear implants, each Satellite III induction loop system improves speech intelligibility for up to 300 people. An Induction Loop Receiver is included for monitoring the system's performance. Low-cost Induction Loop Receivers are available for hard of hearing people who do not own telecoil-equipped hearing aids.

The Cost-Effective Hearing Assistance System

Priced below FM or infrared systems, the Satellite III is a cost-effective hearing assistance system that is ideal for churches, schools, meeting rooms, theaters, libraries and more. And, if your seating area is larger than 300 feet around, you can use additional Satellite III systems to provide adequate coverage.

The Satellite III hearing assistance system comes complete with:

• Satellite III Loop Amplifier
• 500-foot single conductor black/white loop wire - OR - 250 feet two conductor 14 gauge clear
• Induction Loop Receiver with Headphones (x1)
• Signage
• Comprehensive instructions
• 3-year warranty on parts and labor

The Satellite III connects to the audio line level output of most sound systems. If this connection is not available, please click here to learn about the CV-600 loudspeaker output to line output adapter.

Every Oval Window Audio induction loop system complies with the Americans With Disabilities Act and Technical Standard IEC 118-4.

The Satellite III is designed to interface with existing public address systems and is our most popular and cost effective large area induction loop assistive listening system. It is often used in houses of worship, libraries, auditoriums and theatres, providing coverage of up to 300-325 feet in perimeter. In the event larger areas need to be looped, multiple Satellite III systems may be linked, with each system covering no larger than a 300-325 foot perimeter area. Alternatively, two Satellite III amplifiers may be bridged enabling powering of a loop perimeter up to 500 feet (click here for details on the Satellite III bridging feature).

The Satellite III is compatible with all telecoil-equipped hearing aids, cochlear implants and induction loop receivers. (Click on photo to view enlarged image.)
The Satellite III amplifier is designed to be free standing or rack mounted using its built in 2 space rack mount. The amplifier should not be placed near a heat source. At least 1 rack space above and below the amplifier is necessary to permit adequate air circulation.

The Satellite III may be interfaced with any audio line level signal available from the sound system mixer/mixer-amplifier. Appropriate outputs are usually identified as “line” or “auxiliary output.” Use of the Satellite III amplifier’s unbalanced phono input jack is recommended for most installations where the sound system signal feed is short (less than 5 feet). If the signal feed is longer, the balanced input should be used to minimize noise.

<>The area to be looped with each Satellite III should not exceed 300-325 feet in perimeter. The loop wire must fully encompass the listening areas. The Satellite III system is supplied with a spool of 500 feet of high quality 14 gauge stranded wire. The extra wire is provided to allow for connecting the loop to the amplifier.
IMPORTANT LOOP WIRE INSTALLATION INFORMATION:

This loop system includes a 500 foot spool of 14 gauge single conductor stranded wire (black or white color may be specified). The actual perimeter of the area to be looped should not exceed 325 feet per loop system unless a dual amplifier bridged system is used.

The total 14 gauge run of a single loop amplifier wire + lead in should be at least 300 feet so as to present the proper minimum load to the amplifier. If longer lead in wire is needed (exceeding what is available on the 500 foot spool), it should be 10 gauge in order to minimize signal losses.

When looping smaller areas, multiple series loop runs must be installed, for example, two turns around a 150 foot perimeter area. A two turn series loop will result in a 3 dB boost in the signal strength. Please note: Installing a “two turn series loop” means running the loop wire once around, and then continuing around the perimeter one more time. Alternatively, please request information on changing the loop wire gauge.

Important Satellite III installation conditions and recommendations:

· Using the Induction Loop Receiver provided with the system, a pre-installation listening check and measurement should be performed in the areas where loop systems will be installed to ensure that there are no sources of strong electromagnetic fields that can interfere with the system. While holding the induction loop receiver in an upright position, the receiver's LED should not be illuminated by ambient noise. Please contact Oval Window Audio for more information concerning the measurement and mitigation of noise.
· The loop wire may be installed in crawl spaces, under carpeting, in plastic conduit or clips on the wall, on/above ceiling, or simply taped down for temporary use.

· The loop wire may be installed in existing concrete floors by cutting a 1/8” W x >¼” D groove in the floor, placing the loop wire in the groove and filling in the space with epoxy sealer.

· The loop wire may be installed in a newly poured concrete floor by first running the wire through ½-1” PVC conduit. The PVC conduit should be placed in the floor so that it is at least 12” above metal reinforcement bars and within 12” of the flooring surface. The conduit may be tied to wooden support struts before concrete is poured. Alternatively, scaffolding may be used to hold the PVC conduit in place while the concrete is poured.

· In order to maintain proper signal strength and signal uniformity, the loop perimeter in each listening area should not exceed 300-325 feet. The extra wire provided with the systems may be used as loop lead-in wire to connect to the loop amplifier. If longer lead-in wire is needed, 10 gauge wire is recommended in order to minimize power losses.

· Multiple Satellite III systems may be used to cover larger areas. As with stereo/multiple loudspeakers, multiple loop systems must be checked for proper phasing so that the loop signals are working to support each other. Correct phasing will generally occur if all loop wires are installed and connected to the loop amplifiers’ output terminals in the same orientation. For example, all loop wires can start at the “C/-“ terminal and be installed in a clockwise direction around the seating areas. Phasing of multiple loop systems should be confirmed by walking from one looped area to another while monitoring the signals. If the loops are out of phase, there will be a noticeable signal loss in the areas where the loop wires meet. The remedy is to reverse the phasing of one of the loop amplifier outputs. This can also be accomplished by changing the position of the unmarked phase reverse rocker switch on the rear of one of the Satellite III amplifiers.
· Larger areas up to 500 feet in perimeter, may also be serviced by bridging the two Satellite III amplifiers. Click here for information on the Satelllite III's bridging feature.
· Due to “dead spots” that occur directly above and below the loop wire, the sides of the installed loop wire should not be situated directly above or directly below seating within the listening area. The sides of multiple loop wires must meet in areas where there is no seating, such as aisles.

· The loop wire must not be run in continuous contact with metal, either directly above or below the loop wire. Loop wires may cross ceiling framework and may briefly run behind metal furniture. At least 70% of the total loop must be free of metal obstructions.

· At least 70% of the loop wire should be installed in the horizontal plane.

· The loop wire must completely encompass the listening area.

· The height of ceiling loop wires must not exceed 10-12 feet above the floor of the listening area.

· Floor level loop wires must not exceed 3-4 feet below the floor.

· Conventional loops transmit signals that spill outside the looped listening areas. At least twice the length of the longest side of the loop must be allowed between looped areas on the same floor. In regard to loop systems on different floor levels, the systems should be separated by at least one half the length of the longest side of the loop wire.

· Avoid running loop wire in close proximity and parallel to telephone lines, microphone cords and video feeds. Maintain a distance of at 12”.
· The use of dynamic microphones or musical instruments with magnetic pickups can result in equipment damaging feedback. To avoid this, use condenser microphones and/or keep dynamic microphones & musical instrument pickups at least 10 feet from the loop wire.
· Using the Induction Loop Receiver, always begin system set ups with all inputs and output controls at MINIMUM settings, slowly increasing levels until proper signal is attained in the center of the loop. Correct signal strength will light up the Induction Loop Receiver's LED when the receiver is help upright in center of the looped area.
· Please contact us regarding special techniques that may be used to reduce signal spill over.
