Sonance VC30R User manual

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
withAChousewiring,lightswitches,dimmers,oranyother
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).
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.
