OEM Sound Terrain ST-6 Manuals

INSTALLATION GUIDE Landscape Speakers page 1 of 2 Install Guide Rev. A INTRODUCTION Congratulations on the purchase of the ST-6 speaker. The ST-6 has been specially tuned for outdoor use and sounds best in the outdoor environment. Since the ST-6 has a built-in transformer it is ideally suited for use in commercial 70V/100V distributed audio systems in addition to consumer applications with amplifiers that are designed to drive 8-ohm loads. With its 360 degree high fidelity dispersion, the ST-6 creates a rich enveloping listening environment when used in multiples. CONTENTS (1) ST-6 High Performance Landscape Speaker (2) Security Brackets (2) 8mm X 10mm Socket Head Screws (Requires 6mm Hex wrench) ADDITIONAL TOOLS & ACCESSORIES THAT MAY BE REQUIRED Wire cutter / stripper 6mm Hex Wrench (Allen Wrench) (2) Waterproof wire connectors / Silicone filled wire nuts 2-Conductor direct-burial stranded speaker cable SHIPPING DAMAGE Each speaker is thoroughly tested before it leaves the factory. However, in shipment, accidents may occur. Please inspect your speakers carefully when you receive them to make sure there is no damage. If there is, please notify your dealer or supplier immediately for assistance. If you received your speakers by public transportation, report the damage at once to the shipping company. ATTACHING SECURITY BRACkETS Should you wish to restrict movement and/or theft of the ST-6, two security brackets are supplied with each speaker to anchor the speaker into the ground. 1.�Place the speaker upside down on surface that will not damage the top surface. 2.�Install the brackets as shown in the image using the supplied hardware. 3.�Repeat for the 2nd bracket. CONNECTION & SETUP Connection from the speaker to the amplifier should be made with appropriate size cable. Use the chart below to help determine the best wire size. The cable should be rated for direct burial applications. Landscape lighting wire often meets these requirements. Use waterproof wire connectors for all exterior connections. These connectors usually contain a silicone gel to prevent moisture ingression. This type of connector is commonly used for landscape lighting. Connect the short cable that is protruding from the bottom of the speaker to the direct-burial trunk line. Prepare the connections by stripping a short length of insulation from the ends of each wire, exposing approximately 5/8” (15mm) of each conductor, or perform the connections as directed by the manufacturer of the wire connectors. Ensure that the proper polarity is maintained for all connections. This will ensure maximum system performance. Refer to the diagram on the next page. Set the transformer tap position to the desired level. When using multiple speakers on a single line in distributed 70V/100V audio systems, the sum of the power taps selected on all the speakers should approximately equal, but not exceed, the amplifier’s power output. E.g. 24 speakers each set to 8 watts, 24 x 8W=192W, therefore the amplifier should have an approximate power rating of 200W or be limited to approximately 200W output. Note: Not all speakers need to be set to the same position. Overdriving the transformer will cause saturation, distortion, and eventual failure. Setting a high-pass filter at approximately 60Hz will help reduce saturation of the transformer.
