User manual CAMBRIDGE SOUNDWORKS OUTDOOR 42

[. . . ] This manual provides tips and instructions to help you get the most from your loudspeakers. Please read through it carefully before proceeding with the installation. Installing the Outdoor loudspeakers is straightforward and may be performed by an experienced do-it-yourself homeowner. However, some familiarity with typical home construction is necessary. [. . . ] For this reason, we recommend using the gold plated spade lugs we have included to terminate the speaker wire. A properly crimped or soldered connection will create a gas-tight contact surface with the wire which will not deteriorate. The gold-plated contact surfaces of the spade lug and speaker terminal will be resistant to oxidation, making the connection more reliable. It is not mandatory to use the spade terminals. Connecting the wire directly to the terminals will not compromise performance, but you may need to periodically scrape the wire contact surfaces clean if the speakers are left outside year around. solder or crimp 6 OUTDOOR 42/52/62 manual 6/4/02 11:21 AM Page 7 INSTALLATION Building construction practices and materials vary widely based on your geographical region as well as the building's style and age. You will need to adapt these generalized instructions for your specific needs. In particular, the method you use to attach the brackets to the mounting surface will differ for various construction types. Because of this, we have not included hardware to attach the brackets to the building. In most cases this hardware will consist of some form of metal or plastic insert with matching screws. If you are attaching directly to a wood framework, simple wood screws will be all you need. Make sure that whatever hardware you choose is made from rust resistant material, such as Stainless Steel. Your local building supply or hardware store will be best equipped to recommend appropriate mounting hardware for your needs. Remove the bracket from the speaker by removing the thumbscrews and pulling the bracket away from the cabinet while spreading the bracket arms slightly. Decide where you want the speakers to be placed. Use the bracket itself to scribe mounting screw locations through the bracket holes. Use at least two screws in each bracket. It is recommended that a level or plumb bob be used to square the template to other reference points. While there is some degree of freedom to adjust the speaker, it is best to have a level mounting hole pattern to begin with. Drill the mounting holes to the size required by your particular hardware. If you are cutting into a wall or ceiling with a plaster, stucco or adobe surface, drill a small hole first, then increase its size a few steps at a time to reduce the chance of a spreading crack. [. . . ] Contact the retailer where you purchased your loudspeakers, or a Cambridge SoundWorks audio expert for advice on how to best satisfy your needs. Also, keep the volume turned down when connecting or disconnecting components in order to prevent damage from strong, non-musical transients. This will help protect your ears as well as the speakers. Protection Circuit The Outdoor loudspeakers each incorporate a solidstate tweeter protection circuit to reduce the chance of permanent damage as the result of short-term overpowering. When activated, this circuit will cut the signal to the tweeter, and the speaker may sound dull. [. . . ]
