INTRODUCTION  
Thank you for purchasing this Sonance® component. Sonance  
also offers the largest selection of high fidelity in-wall/  
in-ceiling speakers in the world. Consult Sonance literature or  
your Authorized Sonance Dealer for more information on the  
wide variety of speakers, amplifiers, switchers, controls, cable,  
and other custom installation products available from Sonance.  
4. Connect the left speaker wires to the left or Channel-A  
output terminals of the volume control. Check proper polarity  
of wires for correct speaker phase. For example connect the +  
terminal of the speaker to the + VC output, and - to -  
(see diagram 2).  
5. Repeat step 4 for the right or Channel-B speaker connection.  
Please read these instructions carefully before connecting this  
device to your system. If connections are made incorrectly you  
may damage your amplifier/receiver.  
MOUNTING THE CONTROLS:  
IMPORTANT NOTE: TURN YOUR AMPLIFIER/RECEIVER OFF  
BEFORE ATTEMPTING THE FOLLOWING HOOK-UP PROCEDURES.  
Once the unit has been wired, position the volume control with  
terminals at top, and attach it to a standard light switch plaster  
ring or J-box. Use the included screws to attach the  
volume control to the plaster ring or box. Attach the wallplate  
to the control using the screws provided. DO NOT OVER-  
TIGHTEN THE PLATE SCREWS OR YOU MAY DAMAGE THE  
PLATE. Finally, attach the knob to the control shaft  
(See Diagram 3).  
VC30R APPLICATIONS  
The VC30R is a rotary volume control. The volume can be  
controlled by turning the knob clockwise to increase volume  
and counterclockwise to decrease volume. This 10 position  
rotary knob incorporates light touch silent switching  
capabilities and can safely handle 30 watts per channel  
of power.  
OPERATION  
Determine the maximum volume you wish to feed to the rooms  
in which you have volume controls and speakers. With your  
house music source (amplifier/receiver) turned down, turn the  
volume control(s) all the way up. Feed the amplifier/receiver a  
strong music signal, then gradually increase the  
amplifier/receiver volume until the volume in the room(s) is as  
loud as you are likely to ever listen. Take particular care that no  
audible distortion is heard through your speakers or speaker  
damage will occur. If you are using an amplifier with input level  
controls, such as the Sonance Sonamp® series amplifiers, adjust  
the level controls appropriately. Then return to the rooms with  
volume controls and lower the volume settings to normal  
listening levels. Setting the maximum volume will ensure safe  
operation for speakers and amplifiers. If you think there should  
be sound coming from your speakers but do not hear anything  
when the VC is turned all the way up, DO NOT leave it in the  
full ON position when checking your sources or source  
material. Otherwise there may be a startling increase in  
volume when the problem is remedied, and speaker damage  
may occur.  
WIRING AND PLACEMENT  
DO NOT mount the volume control in the same electrical box  
with AC house wiring, light switches, dimmers, or any other  
high voltage device or control. The VC can share gang boxes  
with other low voltage controls such as A/B speaker switches,  
infrared receivers and emitters, and other volume controls if  
these other devices are rated as Class 2 devices by the National  
Electrical Code. With 14-18 gauge wire the volume control  
between a single pair of speakers and the amplifier powering  
those speakers. Run four wires for carrying speaker signals  
(L+, L-, R+, and R-) from the amplifier, through the walls or  
ceiling, to the volume control.We recommend high quality wire  
like Sonance MediaLinQ®. If using free standing speakers, run  
the wire through the wall or ceiling to a convenient location  
near the speaker and terminate it with a Sonance FielDress™  
series system terminator or other audio jack.  
INSTALLATION FOR VC30R (SEE DIAGRAM 1)  
1.Once the speaker wires have been run, install a standard light  
switch plaster ring or J-box that is approximately 3in depth,  
available from an electrical supply source.

2. TURN THE AMPLIFIER/RECEIVER POWER OFF. Then  
connect the left or Channel-A speaker output, of the  
amplifier/receiver, to the left screw-to-connect input terminals  
of the volume control, observing proper polarity. For example  
connect L+ of the amplifier to L+ of the VC, and L- to L-  
(see diagram 2).
