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.

Please read these instructions carefully before connecting this device to your system. If connections are made incorrectly you may damage your amplifier/receiver.

IMPORTANT NOTE: TURN YOUR AMPLIFIER/RECEIVER OFF BEFORE ATTEMPTING THE FOLLOWING HOOK-UP PROCEDURES.

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.

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 3” in 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).

I N S TA L L AT I O N I N S T R U C T I O N S

V C 3 0 R	R O T A R Y	I N - W A L L
S T E R E O	V O L U M E	C O N T R O L

3.Repeat step 2 for the right or Channel-B speaker output.

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.

MOUNTING THE CONTROLS:

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).

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.
