of attenuation instead of 8. Steps 11-6 attenuate -3 dB per  
step; steps 5-2 are -6 dB per step. Step 12 is full-on” and step  
1 is full-off. The VCS-2D-HP delivers “POP-FREE” switching  
between all steps.  
Silent When Off – Niles controls completely silence your  
speakers when they are at the full-off position  
Removable Connnectors – The connectors on the VCS-  
2D-HP are removable and accommodate up to 14 gauge  
speaker wire. The connectors simplify your installation:  
• The speaker wires are easier to attach—no heavy  
control to hold onto.  
• The control may be removed without disconnecting  
any wiring.  
• ”Wire-Guard” barriers between each connector  
terminal reduce the chance of a short-circuit.  
Mounting depth of only 2 9/16. Fits into standard 18 cu. in.  
1-gang electrical boxes.  
Printed circuit board construction uses no hand wiring,  
assuring high reliability.  
Tested Performance – 100% tested, electronically and  
acoustically, for frequency response, distortion and power  
handling.

P-Rings and Electrical Boxes  
The mounting depth of the VCS-2D-HP is 2 9/16. When  
installed, the unit extends 2 5/16” behind the sheetrock wall  
(assuming 1/ 2” sheetrock). For installation, you must choose  
between a standard light switch plaster ring (p-ring) or a  
standard 18 cu. in. (or larger) electrical box. Suitable p-rings  
and electrical boxes are available from your Niles dealer or  
local electrical supply company. Using the p-ring is best  
because it gives you unobstructed access to the full depth

of the wall. In some instances, the use of a p-ring may be  
inappropriate, such as in a retro-fit (existing) installation, or  
when building codes require that wall devices be enclosed  
in electrical boxes. Contact your local building code and  
inspection department if unsure.  
"Tech Tip"  
Type of Speaker Wire  
For most applications, we recommend you use 16 or 18  
gauge, stranded copper speaker wire for the VCS-2D-HP  
connections. For wiring runs longer than 80 feet, 14 gauge  
wire is recommended. Using speaker wire larger than 14  
gauge for the VCS-2D-HP connections is not recommend-  
ed —the wire may not fit into the connectors. Never use  
solid-core, aluminum, or “Romex” type wire with the VCS-  
2D-HP. 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 CLfire 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.  
Wire size is  
expressed by it's  
AWG (American  
Wire Gauge)  
number. The lower  
the AWG number,  
the larger the wire,  
i.e., 12 AWG wire is  
physically larger than  
14 AWG.

VCS-2D-HP Mounting Location  
Convenient mounting locations for the VCS-2D-HP are:  
Near entryways or exits  
Near a desk  
At your bedside  
Close to a telephone  
Near other wall controls (see caution next page)  
DO NOT INSTALL THE VCS-2D-HP INTO ELECTRICAL  
BOXES WITH 110 VOLT DEVICES  
Some states or municipalities allow devices such as the VCS-  
2D-HP to be installed into the same electrical box as 110 volt  
devices, provided a “low-voltage partition” 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 the VCS-2D-HP 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.

1. Obtain the VCS-2D-HP knob and Decora-style insert in  
the desired color from your Niles dealer.  
2. Holding the VCS-2D-HP control as shown in (Figure 1),  
make sure that the knob is turned completely counter-  
clockwise, to the off position. Note the current position of  
the knob; this will ensure that you install the new knob in  
the same position as the old one. Next, using a 5/64” allen  
wrench/driver, locate the two set screws on the side of the  
knob and carefully loosen both screws until the knob may  
be removed. It is not necessary to completely remove the  
screws from the knob.  
3. Next, holding the control as shown in (Figure 2), 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 mount-  
ing slots.

Removing the  
Decora-style Insert  
4. Locate the new Decora-style insert. Hold the control so  
that it is facing you. Insert the two bottom tabs into the  
bottom slots first, followed by the two tabs on the top. Snap  
the insert into place by carefully pressing on the front of the  
insert.  
"TECH TIP"  
Do not exert  
excessive pressure on  
the plastic  
mounting tabs.  
5. Locate the new knob. Place the new knob onto the shaft  
and align it to the same position as the old one. Secure the  
knob to the shaft by tightening the two set screws on the  
side of the knob. Holding the VCS-2D-HP as shown in  
(Figure 1), check the alignment of the knob by turning it  
through all positions.

In st allat ion  
If you are installing the VCS-2D-HP 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.  
Figure 3  
Wiring the Connectors  
1. Install the electrical box or p-ring in the usual manner.  
2. Run all the necessary wiring to the VCS-2D-HP. Label the  
wires for future reference.  
RECEIVER  
3. Make the connections to the VCS-2D-HP. Locate the  
connectors for the VCS-2D-HP (remove them if they are  
plugged in). Next, 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 removable connector blocks; secure the wiring to  
the connectors by tightening the small connector screws.  
Be certain that proper phasing is observed —connect the  
positive terminals on the VCS-2D-HP to the positive termi-  
nals on the amplifier and speakers; the negative terminals  
on the VCS-2D-HP to the negative terminals on the amplifi-  
er and speakers. See (Figures 3 and 4).  
From Amplifier (Input)  
VCS-2D-HP  
To Speakers (Output)  
The input s of t he VCS-2D-HP are t he connect or pins  
labeled “AMPLIFIER.” The outputs are the connector pins  
labeled “SPEAKERS. Be sure not to reverse these connec-  
tions or the VCS-2D-HP will not function properly.

4. Plug the connectors into the VCS-2D-HP as shown in  
(Figure 5)  
5. Secure the VCS-2D-HP to the electrical box or p-ring.  
Insert the 11/4” long device screws into the oblong-shaped  
screw holes on the top and bottom of the VCS-2D-HP.  
Note that the oblong shape of the screw holes allow you to  
position the VCS-2D-HP so that it is vertical. Position the  
VCS-2D-HP so that the screws are aligned with the thread-  
ed holes in the electrical box or p-ring. 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 VCS-2D-HP to fit flush with the Decora  
cover plate. See (Figure 6).

Installing the  
Connectors  
6. Use the shorter plate screws to fasten the Decora faceplate  
to the VCS-2D-HP. DO NOT OVER-TIGHTEN THE 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 these screws completely. To make the clear-  
ance necessary for these screws, you must remove the parts  
of the lip causing the interference. There are two ways to  
accomplish this:  
Figure 6  
Loosening the Screws  
for a Flush Fit  
1. Drill through the lip of the box at the screw points.  
2. Cut notches into the lip with a pair of diagonal cutters.
