Setting Up
Mounting your speakers on a wall 
CAUTION:  
Do not mount the brackets on surfaces that are not 
sturdy enough, or that have hazards concealed behind them, 
such as electrical wire or plumbing. If you are unsure about install-
ing the bracket, contact a qualified professional installer. 
CAUTION:  
Do not hang items from the brackets or speakers. The 
brackets were designed to support the weight of the speakers 
only. 
Note:  
See the back pages of this guide for the mounting template 
and hardware information. 
Note:  
For vertical mounting, mount part A with the hole for screw 
C at the bottom. Be sure to tighten all screws. 
Note:  
For Stereo Everywhere 
® 
 speaker performance, horizontal 
mounting is required. 
1. Hold the mounting template in position and mark holes for the 
mounting hardware. If you plan to feed wires through the wall, 
mark the speaker wire pilot hole also. 
2. Drill holes for the chosen mounting hardware.
3. Mount bracket part A to the wall and mount bracket part B to 
the rear of the speaker (Figure 8).
4. Secure the speaker with bracket part B to bracket part A 
using screw C. To adjust the angle, loosen screw C slightly, 
move the speaker up or down, and retighten screw C.

Adjusting Your Surround Sound Settings
For realistic home theater sound
Each speaker produces only the sound directed to it by your sur-
round sound receiver. During a surround sound program, the front 
and center speakers will emit sound almost constantly, while the 
surround speakers may be silent at times. 
How to set your Pro-Logic receiver 
For use in video applications, be sure the SURROUND SOUND 
center mode setting of your receiver is on NORMAL (Figure 9). You 
may press in the button labeled Loudness (Bass Boost or Super 
Bass on some receivers) to see if you prefer that video sound.

amplifier set to

Use the test tone on your receiver to further verify connections 
and to adjust the volume level of the speakers. 
To use the test tone
1. Press test tone ON at the receiver remote.  
2. Listen and confirm that each speaker reproduces sound as 
the tone moves from speaker to speaker. One tone should 
come from both SURROUND speakers at the same time. 
3. Adjust the volume levels of the CENTER and SURROUND 
speakers so all of the speakers sound equally loud in your 
main listening area.
Instructions for this process vary, depending on the receiver brand 
and model you are using. Follow your receiver owner’s guide 
instructions for more details on using the test tone.
To balance the bass and treble
Upholstered furniture, wall-to-wall carpets, or heavy drapes can 
muffle treble (high notes), making your speaker system sound 
bass heavy. Bare floors and walls and hard surface furniture can 
make your speaker system sound too shrill. After listening to your 
speakers, you may want to adjust the balance of bass and treble. 
You can use the bass and treble controls on your receiver.

Adjusting Your Surround Sound Settings
How to set your Dolby Digital receiver
Your VCS-10® or VCS-30® Series II speakers are compatible with 
the output from Dolby Digital receivers. Take special care to set 
the channel output on the Dolby Digital screen menu to SMALL for 
both the center speaker and surround speakers.
Follow the receiver owner’s guide instructions for using the 
receiver test tone to verify your connections and to adjust the vol-
ume levels of the speakers. 
If the sound is interrupted
The VCS-10 Center Speaker and VCS-30 Series II Center/Sur-
round Speaker System feature an advanced automatic electronic 
protection circuit to prevent speaker damage due to an overload.
When the center channel speaker detects an overload, the protec-
tion circuit intermittently shuts down and resets the speaker a 
fraction of a second later, until the overload is cleared. Intermittent 
play will continue for the duration of the overload. 
If you hear this interruption, turn down the volume to relieve the 
overload. You will hear the speaker resume normal play when the 
volume is set at a safe level.
Note: The overload problem described here should occur only if 
the receiver is overdriven and sending a distorted signal, or when 
the center speaker is driven by an amplifier rated well above the 
100 watts per channel maximum listed in “Compatibility” on 
page 15.Receiver channel output Proper setting

the sound source (DSS, laserdisc, or DVD player) is con-
nected directly to your receiver as described in your 
receiver owner’s guide.
