Niles Audio VCS50 Installation, Operation, Changing The Color Of The Knob And The, Decora Insert

INSTALLATION CONSIDERATIONS

CHANGING THE COLOR

OF THE KNOB AND THE

DECORA INSERT

The Decora-style insert and knob on the VCS50 are removable, allowing fast and easy color changes as needed. Inserts and knobs are available in a variety of colors. To change the color of your unit:

1.Obtain the appropriate knob and Decora- style insert in the desired color from your Niles dealer.

2.Pull the knob off the shaft. See Figure 1.

3.Locate the two plastic mounting tabs at the top rear of the Decora-style insert. Using two fingers, simultaneously press both tabs down (towards the center of the insert) and forward (away from you) until the insert pops free from its mounting slots.

4.Locate the new Decora-style insert. Hold the volume control facing you. Insert the two bottom tabs into the bottom slots first, then the two tabs on the top (see Figure 1). Press carefully on the front of the insert to snap it into place.

5.Locate the new knob. Align its flat side to the flat side of the shaft, and push the knob onto the shaft. Check the alignment of the knob by turning it through all positions.

INSTALLATION

If you are installing the VCS50 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 or other types of wiring; plumbing; conduit; old wall safes; etc.

1.Install the junction box in the usual manner.

2.Run all the necessary wiring to the VCS50. Label the wires for future reference.

3.Make the connections to the VCS50. Locate the connectors for the VCS50. 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 tight- ening the small connector screws. Be certain that proper phasing is observed— connect the positive terminals on the VCS50 to the positive terminals on the amplifier and speakers; the negative terminals on the VCS50 to the negative terminals on the amplifier and speakers. See Figures 2 and 3.

NOTE: THE INPUTS OF THE VCS50 ARE THE CONNECTOR PINS LABELED “IN”. THE OUTPUTS ARE THE CONNECTOR PINS LABELED “OUT”. BE SURE NOT TO REVERSE THESE CONNECTIONS OR THE VCS50 WILL NOT FUNCTION PROPERLY.

4.Secure the VCS50 to the junction box. Insert the 1-1/4" long device screws into the oblong- shaped screw holes on the top and bottom of the VCS50. Note that the oblong shape of the screw holes allow you to position the VCS50 so that it is vertical. Position the VCS50 so that the screws are aligned with the threaded holes in the junction box. Tighten the screws using a phillips screwdriver. DO NOT OVER- TIGHTEN. In some instances, you may need to loosen these screws several turns to allow the VCS50 to fit flush with the Decora cover plate. See Figure 4.

5.Use the shorter plate screws to fasten the

Decora faceplate to the VCS50. DO NOT OVER-

TIGHTEN THE PLATE SCREWS OR YOU MAY DAM- AGE THE FACEPLATE. Line up all the screws in the same direction for a finished look.

	system with a VCS50	“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 using the VCS50. 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.
