User manual NILES SCW-1D

[. . . ] It connects between the speaker-level output of an amplifier, speaker selector, etc. A perfect application for the SCW-1D is adjusting the volume of remotely located speakers. The SCW-1D adjusts the volume of speakers connected to it by attenuating the amplifier signal. Niles volume controls use autoformers instead of L-pads for the volume controlling element.

Printed in the USA 11/96 DS00172A Niles Audio Corporation Installation Considerations The SCW-1D is a Decorastyle module designed to use "Decora-style" faceplates and mounting hardware. Decora faceplates (up to 6-gang) with colormatched plate screws are available from your Niles dealer. Contact your local building code and inspection department if unsure. Type of Speaker Wire For most applications, we recommend you use 16 or 18 gauge, stranded copper speaker wire for the SCW-1D and connections. For wiring runs longer than 80 feet, 14 gauge wire is recommended. Using speaker wire larger than 14 gauge for SCW-1D and connections is not recommended -- the wire may not fit into the connectors. Never use solid-core, aluminum or "Romex" type wire with the SCW-1D. When running speaker wires inside walls, most states and municipalities in the U. S. specify that you must use a special type of speaker wire. Usually, the requirement is that the wire has a specific "CL" fire rating, such as "CL-2" or "CL-3". Consult your Niles dealer, building contractor, or local building and inspection department if unsure about which type of wire is best for your application. DO NOT INSTALL THE SCW-1D INTO ELECTRICAL BOXES WITH 110 VOLT DEVICES. Some states or municipalities allow devices such as the SCW-1D to be installed into the same electrical box as 110 volt devices, provided a "low-voltage partition" is used between the devices. Speaker wires can act as an "antenna" for electrical noise. Locating speaker wires too close to a light switch or dimmer may cause a "popping" or "buzzing" sound to be heard through the speakers. If you must locate an SCW-1D near electrical devices, install it in a separate metal electrical box, ground the box to the electrical system ground, and route the speaker wires several feet away from the electrical wiring. Receiver Installation If you are installing the SCW-1D into an existing wall, take time to consider any possible obstructions which may be hidden inside the wall, such as wood and metal studs; electrical, telephone wire or other types of wiring; plumbing; conduit; old wall safes; etc. Install the electrical box or p-ring in the usual manner. Run all the necessary wiring to the SCW-1D. [. . . ] To make the clearance necessary for these screws, you must remove the parts of the lip causing interference. There are two ways to accomplish this: 1. Drill through the lip of the box at the screw points. Cut notches into the lip with a pair of diagonal cutters. SCW-1D Mounting Locations Convenient mounting locations for the SCW-1D are: · Near entryways or exits · Near a desk · At your bedside · Close to a telephone · Near other wall controls P-Ring and Electrical Boxes The mounting depth of the SCW-1D is 2-3 /8".
