Operation

1.Make sure the amplifier or receiver is OFF and set the volume to minimum.

2.Set the SCW-1Dvolume to maximum (fully clockwise).

3.If you are using a Niles speaker selector system, locate the ON/OFF button which corresponds to the speaker pair you wish to play. Set it to the ON position.

4.Turn on the amplifier or receiver and select a source, such as tuner or CD player.

5.Slowly turn up the amplifier or receiver volume and set it to a comfortable (not maximum) listening level. Be careful not to overdrive or “clip” your amplifier. If the sound becomes muddy or distorted, you have reached the limit of your amplifier’s volume capability and should quickly reduce the volume to avoid damaging your speakers.

6.Adjust the volume of the speakers to the desired listening level by using the

SCW-1D.If all the speaker pairs in your system are equipped with Niles volume controls, you can leave the amplifier or receiver volume set at one position and use the Niles controls exclusively.

7. You can turn off the speakers by turning the knob on theSCW-1Dcompletelycounter-clockwise,or by pressing the ON/OFF button on your speaker selector.

SCW-1D

STEREO WALL-MOUNTVOLUME CONTROL

Introduction

The SCW-1Dis awall-mount,Decora® style speaker volume control. It connects between thespeaker-leveloutput of an amplifier, speaker selector, etc. and a pair of speakers. A perfect application for theSCW-1Dis adjusting the volume of remotely located speakers.

The SCW-1Dadjusts the volume of speakers connected to it by attenuating the amplifier signal. Niles volume controls use autoformers instead ofL-padsfor the volume controlling element. The autoformers assure minimal internal power dissipation with virtually no power wasted as heat.

Features and Benefits

Boxes

The mounting depth of the SCW-1Dis2-3/8”.When installed, the unit extends1-7/8”behind the sheetrock wall (assuming 1/2” sheetrock). For installation, you must choose between standard light switch plaster ring(p-ring)or a standard 18 cubic inch (or larger) electrical box. Suitable rings and electrical boxes are available from your Niles dealer or a local electrical supply company. Using thep-ringis best because it gives you unobstructed access to the full depth of the wall. In some instances, the use of ap-ringmay be inappropriate, such as in aretro-fit(existing construction) installation, or when building codes require that wall devices be enclosed in

electrical boxes. 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-1Dand connections. For wiring runs longer than 80 feet, 14 gauge wire is recommended. Using speaker wire larger than 14 gauge forSCW-1Dand connections is not recommended — the wire may not fit into the connectors. Never usesolid-core,aluminum or “Romex” type wire with theSCW-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

DO NOT INSTALL THE SCW-1DINTO ELECTRICAL BOXES WITH 110 VOLT DEVICES.

Some states or municipalities allow devices such as the SCW-1Dto be installed into the same electrical box as 110 volt devices, provided a“low-voltagepartition” is used between the

devices. We do not recommend this. 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-1Dnear 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.

Installation

If you are installing the SCW-1Dinto 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.

1.Install the electrical box or p-ringin the usual manner.

2.Run all the necessary wiring to the SCW-1D.Label the wires for future reference.

3.Make the connections to the SCW-1D.Strip 1/4” of insulation from the end of each wire. Tightly twist the end of each wire until there are no frayed ends. Insert each wire into the appropriate hole on the connector blocks; secure the wiring to the connectors by tightening the small connector screws. Be certain that

terminals on the SCW-1Dto the positive terminals on the amplifier and speakers; the negative terminals on theSCW-1Dto the negative terminals on the amplifier and speakers.See Figure 1.

4. Secure theSCW-1Dto the electrical box orp-ring.Insert the1-1/4”long device screws into the oblongshaped screw holes on the top and bottom of theSCW-1D.Note that the oblong shape of the screw holes allow you to position theSCW-1Dso that it is vertical. Position theSCW-1Dso that the screws are aligned with the threaded holes in the electrical box orp-ring.Tighten the screws using a philips screwdriver. DO NOTOVER-TIGHTEN.In some instances, you may need to loosen these screws several turns to allow theSCW-1Dto fit flush with the Decora cover plate.

5. Use the shorter plate screws to fasten the Decora faceplate to theSCW-1D.DO NOTOVER-TIGHTENTHE PLATE SCREWS OR YOU MAY DAMAGE THE FACEPLATE. Line up all the screws in the same direction for a finished look. NOTE: Certain “old work” or“retro-fit”boxes, such as the Carlon B225R, have a plastic “lip” which interferes with the Decora faceplate screws. This lip prevents you from being able to tighten the screws completely. 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.

2.Cut notches into the lip with a pair of diagonal cutters.
