1. Review the Placement Guidelines section below.
2. Review the Placement Cautions section below.
3. Select a subwoofer placement location based on the placement cautions and guidelines.
4. Before you remove the subwoofer from the box, place the box near where you want to place the
subwoofer in your room. If you’ve already unpacked the subwoofer, move the subwoofer to where you
want it in the room.
NOTE: Later, we’ll guide you to optionally adjust the location of the subwoofer for your listening
preferences.
5. Go to the Box Contents section next.
The seating positions shown in the diagram above are general guidelines for most room types and aren’t
dependent on the subwoofer placement. Sitting closer to the front in a “boomy bass” room may sound better.
Sitting closer to the back of a “bass shy” room may sound better.
Subwoofer Placement Guidelines
REFER to the RECOMMENDED SINGLE SUBWOOFER PLACEMENT diagram above for general seating and
subwoofer placement guidelines.
PLACE in a CORNER (loudest) or within a FEW FEET of a WALL (smoothest). AVOID locations FAR AWAY from
a WALL, CLOSE to the ROOM CENTER, BY a DOOR, NEAR a PARTIAL-HEIGHT WALL, or BEHIND SEATING
ARRANGEMENTS. FACE the GRILLE TOWARDS the room’s main SEATING location.
MAKE SURE:
• You can access the controls on the rear of the subwoofer.
• The included 6’ power cord for the subwoofer can safely reach a power outlet.
Subwoofer Placement Cautions
PLACE THE SUBWOOFER CABINET ON A STABLE, FLAT AND LEVEL SURFACE. An uneven or unstable
surface can cause the subwoofer to tip over and cause injury or be damaged. Protruding objects from the
surface or an uneven surface could cause damage to the speaker cone on the bottom of the cabinet.
DO NOT CREATE A TRIP HAZARD WITH THE POWER CORDS. Route power cables so that they cannot be
tripped on by persons walking in the room.
DO NOT BLOCK THE SOUND PORT. The sound port is located in the back of the cabinet above the cable
connection sockets.
PLACE THE SUBWOOFER ON THE FLOOR. If the subwoofer is placed on a stand, bracket, tripod, table or
similar device, it could fall or be knocked over causing injury to persons or damage to the subwoofer and other
items.
KEEP THE SUBWOOFER IN ITS UPRIGHT POSITION.

Connect Subwoofer
1. Use the included power cord to connect the subwoofer to a power outlet.
2. Turn the POWER switch to the ON position. The ACTIVE light should be yellow.
NOTE: After 12 minutes without receiving a signal, the ACTIVE light turns red to indicate STAND BY mode. The
subwoofer will automatically go from STAND BY mode to ACTIVE when it detects an audio signal.
3. Turn the VOLUME knob to MIN to prevent blasting music when you rst use the subwoofer. You can
increase the VOLUME to the correct level later.
4. You’re done. No more wires to connect!
5. Go to the Select Wireless Broadcast Channel instructions next.
Select Wireless Broadcast Channel
The wireless transmitter can broadcast your audio signals on one of four selectable channels. Multiple channels
are made available in case other devices in your home are using some of the channels for communication.
To select the broadcast channel:
1. Review the Wireless Broadcast Considerations below.
2. Use the CHANNEL switch on the back of the wireless transmitter to select “1”, “2”, “3”, or “4” as the
broadcast channel.
3. Use the CHANNEL switch on the back of the subwoofer to select the same broadcast channel as you
selected on the wireless transmitter.
4. Go to the Adjust Subwoofer Controls for Listening Preferences instructions next.
Wireless Broadcast Considerations
All wireless devices like the WiC-10 may be susceptible to radio frequency (RF) interference from other devices.
Other RF devices include WiFi Internet access, computer equipment and routers; WiFi solar panel monitoring
systems; video game consoles, cordless telephones, blue tooth devices, baby monitors and microwave ovens.
In particular, any devices operating in the 2.4 GHz band may cause intermittent wireless connections between
the wireless transmitter and subwoofer.
To prevent wireless broadcast interference problems, keep wireless devices at least 2’ apart. Any interference
eects from a microwave oven will cease once the oven stops operating and may be resolved on a long-term
basis by increasing the physical distance between the subwoofer and the microwave oven.
If the WiC-10 sound is intermittent, check that another wireless device isn’t within 2’ of either the wireless
transmitter or the subwoofer.

Adjust Subwoofer Controls for Listening Preferences
Now it’s time to adjust the subwoofer controls to match your listening environment and preferences.
1. Play some music through your receiver.
2. Turn the subwoofer’s VOLUME to a level that balances with the output volume of your satellite speakers
and doesn’t distort the bass sounds. You might also want to adjust your receiver’s LFE output volume
higher, if you can’t get a loud enough subwoofer output, or lower, if the subwoofer output is too loud.
3. If you didn’t use the LFE INPUT on the wireless transmitter, optionally, adjust the subwoofer’s LOW
PASS FREQUENCY to provide a wireless transmitter input equivalent to an LFE input. The LOW PASS
FREQUENCY is the frequency at which the subwoofer’s output starts to decrease as the frequency
increases. Your satellite speakers output the frequencies not covered by the subwoofer. You want to
not be able to hear the transition from the subwoofer output to your satellite speakers’ output. You can
adjust this frequency from between 50 Hz to 200 Hz. To adjust this frequency:
a. If your satellite speakers are small with limited low frequency output, choose a LOW PASS
FREQUENCY of between 100 Hz and 120 Hz.
b. If your satellite speakers are larger with better low frequency output, choose a LOW PASS FREQUENCY
of around 80 Hz.
c. Adjust the LOW PASS FREQUENCY based on listening to your audio system until it sounds pleasing to
your ear.
4. Optionally, switch the subwoofer’s PHASE to 180°. This reverses the phase of the subwoofer to correct
for sound cancellations between your subwoofer and your satellite speakers. To determine which PHASE
is best for your room and subwoofer location:
a. Listen to the system with music playing.
b. Ask a friend to switch the PHASE switch from 0° to 180° while you listen for a change in the mid-
bass loudness.
c. The correct PHASE is the one that you hear as having louder mid-bass.
d. If you can’t tell a dierence, keep the phase at 0°.
5. Go to the Adjust Subwoofer Location for Listening Preferences instructions next.
Adjust Subwoofer Location for Listening Preferences
Optionally, you can now optimize the location of the subwoofer for your listening preferences by either using the
“Crawl Test” or the “Move Test.”
Crawl Test
In this test, the subwoofer stays in one spot and you move around the room to dierent listening spots. To do
the “Crawl Test”:
1. Place the subwoofer on the oor or table near your most often used seating location. Velodyne doesn’t
recommend placing the subwoofer on the actual seating surface. The weight of the subwoofer or its
corners could damage the seating surface or structure. Also, placing the subwoofer on a very soft
surface, such as a sofa cushion, will not allow the downward ring speaker cone to extend out freely
without hitting the surface and causing damage to the speaker.
2. Play some music on the audio system.
3. Crawl around to various spots in the room until you hear the best sounding bass output to you. When
you hear the best bass output, you have determined the placement of the subwoofer for your listening
preferences.
4. Re-locate the subwoofer from the seating location to the spot you crawled to that sounded the best.
5. You’re done with this best placement test and setting up the subwoofer. Enjoy!

10 - WiConnect User’s Manual
Move Test
In this test, you stay in one listening spot and you move the subwoofer around the room. To do the “Move Test”:
1. Place the subwoofer in a new location in the room.
2. Sit in the seating location you use most often.
3. Play some music on the audio system.
4. Listen to the audio output.
5. Repeat Step 1 through Step 4 until you hear the best sounding bass output to you. When you hear the
best bass output, you have determined the placement of the subwoofer for your listening preferences.
6. You’re done with this best placement test and setting up the subwoofer. Enjoy!
Connect Multiple Wireless Subwoofers
In a Single Audio System
If you are using more than one wireless subwoofer in a single audio system, the following two setup options
exist.
OPTION #1: All subwoofers receive the same audio signal. This is the most common setup. For this setup:
1. Connect only one wireless transmitter to your receiver. Follow the instructions for OPTION #1 or OPTION
#2 in the Connect Wireless Transmitter Section.
2. Follow the instructions for SETUP #1 in the Select Receiver Options for Optimal Subwoofer
Performance section.
3. Set the same wireless broadcast channel on the wireless transmitter and all subwoofers. Follow the
instructions in the Select Wireless Broadcast Channel section.
4. Follow the instructions in the Adjust Subwoofer Controls section for each subwoofer.
OPTION #2: Subwoofers receive dierent audio signals. This is a less common setup. Usually, this setup uses
one subwoofer for the R audio channel and one subwoofer for the L audio channel. If using separate R and
L channel subwoofers, place each subwoofer within a couple of feet of the appropriate main speaker for the
channel. If the system’s crossover frequency is high, each subwoofer should be even closer to its channel’s
main speaker. For this setup:
1. Connect a wireless transmitter to each signal you want to transmit to a subwoofer. Usually, one for the
R and one for the L channel. Follow instructions for SETUP #2 in the Connect Wireless Transmitter
Section, except pair one transmitter’s R input to the R channel receiver output and the other transmitter’s
L channel input to the L channel receiver output.
2. Follow the instructions for OPTION #3 in the Select Receiver Options for Optimal Subwoofer
Performance section.
3. Follow the instructions in the Select Wireless Broadcast Channel section, except:
a. Select a unique wireless broadcast channel for each wireless transmitter.
b. Match the wireless broadcast channel on each subwoofer to that of the wireless transmitter that
broadcasts the audio signal the subwoofer is to output.
4. Follow the instructions in the Adjust Subwoofer Controls section for each subwoofer.
In Separate Audio Systems
If you have multiple audio systems in your home, such as one in the family movie room and another in a
bedroom or oce, you can use a separate wireless transmitter in each system. In this case, use a dierent
wireless broadcast channel for each system, to avoid the subwoofers from getting input from multiple systems
due to the close proximity of the systems.

www.velodyne.com WiConnect User’s Manual - 11
Use the Subwoofer’s LFE Input (Optional)
In case you misplace the wireless transmitter or the wireless transmitter malfunctions, you can also connect the
subwoofer to your receiver with an RCA cable.
1. Use the RCA cable, supplied by you, to connect one end of the RCA cable to the subwoofer’s LFE In
input.
2. Connect the other end of the RCA cable to either the receiver’s:
• LFE or SUB output
• Or the R output channel (red or purple connector)
• Or use a “Y” connector (notincluded) to connect both the Rand L output channels
3. Go to the Adjust Subwoofer Controls for Listening Preferences instructions next.
NOTE: Do not use the subwoofer’s LFE connection option if you are already using the wireless connection
option.

12 - WiConnect User’s Manual
Mount Wireless Transmitter on Wall (Optional)
Optionally, you can mount the wireless transmitter on the wall or place in a location that better organizes your
audio components. The transmitter doesn’t have to be visually in view in the room to function properly.
1. Use the template below to mark the mounting locations on the wall. Mark the two screw locations for
either the horizontal or vertical mounting orientation.
2. Hand turn one of the included self-tapping wood screws into each marked location. Tighten the screws
until about 1/8” (3.17mm) of the screw shank is exposed.
3. Hook two of the slotted holes on back of the wireless transmitter to the two screws. There is no right way
up for the transmitter. It can be mounted in any orientation.
NOTE: The provided wood screws aren’t suitable for stone or other hard wall surfaces. If you can’t hand drive
the screws, you may need to drill holes and provide other wall anchors.
