INSTALLATION/SETUP INSTRUCTIONS
1. Make sure your subwoofer is turned off to avoid any possible damage.
2. The WL-RX SUB receiver includes a universal adaptor designed to operate on house-
hold power of 100-240V and 50/60 Hz. Plug the power adapter into a convenient
power outlet and the small coaxial DC power plug into the transmitter socket labeled
“DC In +5V”. The receiver should power up and display a red LED light on the front of
the unit.
3. Connect the attached RCA audio cable labeled SUB OUT on the wireless receiver to
the Line, LFE or RCA input connection on your subwoofer amplifier.
For the subwoofer receiver to function there are three steps (steps 4, 5 and 6) that you
must do with your Phase Technology WL-3TX transmitter.
4. Connect an RCA cable (not supplied) from the subwoofer output jack on your home
theater receiver or processor to the subwoofer input jack (yellow) on the WL-3TX trans-
mitter.
5. Set the channel selection switch on the WL-RX SUB receiver to the same setting as
on the WL-3TX transmitter. This switch is located on the side of the receiver, and on
the right rear corner of the transmitter. Both are labelled “Wireless Channel” and have
the options of 1, 2, or 3.
6. Turn on the transmitter. The LED light on the receiver should change from red to
blue. A blue light means that the receiver is linked to the transmitter and ready for use.
7. Follow your subwoofer’s manual and set controls for the subwoofer. Keep the vol-
ume turned down low, and turn the subwoofer on. Gradually increase the volume to
the desired setting.
8. There is a hook and loop pad provided with the receiver with an adhesive backing
for easy attachment of the receiver to the rear of your subwoofer or any other smooth
clean surface.
MULTIPLE SUBWOOFERS
To add a second subwoofer to the same system, use a second WL-RX SUB receiver and
connect it to the second subwoofer following the steps above. Set the second WL-RX
SUB receiver to the same wireless channel as the first.
To set up a second wireless system in a different room within the same house, set up
the second transmitter and receiver using a different channel. For example, a wireless
transmitter and subwoofer in the family room could be set to channel 1, while a wire-
less transmitter and subwoofer in the master bedroom operate on channel 2.
Up to three transmitter/receiver systems can be operated in a single home, using
channels 1, 2, and 3.
TROUBLESHOOTING
• NO POWER- Check for a loose connection at the power jack on the receiver or wall
adapter. Verify that the receiver adapter is plugged into a live power outlet.
• POWER BUT NO SOUND- Be sure that the LED on the front of the receiver is blue,
indicating an RF link from the transmitter. Check cable connections from the wireless
receiver to the subwoofer and also the from your receiver/processor to the transmit-
ter. Make certain that your receiver/processor has the subwoofer function turned on
in the setup menu.
• INTERFERENCE, NOISE, INTERMITTENT OPERATION- Even though Phase Technology
wireless products use advanced digital wireless technology, as with any wireless prod-
uct the possibility of interference or noise reception does exist. Problems with interfer-
ence, noise or intermittent operation might be caused by other products that share
the 2.4 GHz radio band. This is most likely to occur if the transmitter and receiver are
being operated near their range limits. This might also occur if there is a strong local
source very close to the receiver.
o Turn off or relocate any equipment that might be operating on the 2.4 GHz
band.
o Check the distance between the transmitter and receiver and move closer if
possible. The audio cables can be extended if necessary for better placement
positioning.
o Building construction or large metal objects can reduce the strength of the
radio signals. Concrete and steel do not pass radio waves well. Try relocating the
receiver or transmitter to improve the signal strength.

lems that these trouble shooting tips do not solve, please contact your Phase Technol-
ogy dealer or our customer service department at (888) PHASE-TK.
