Phase Technology WL-RX SUB Manuel D’Utilisation

WL-RX SUB INSTALLATION/SETUP

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 household 

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 the-

ater receiver or processor to the subwoofer input jack (yellow) on the WL-3TX transmitter.

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 volume 

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.

WL-3TX INSTALLATION/SETUP

The WL-3TX transmitter supplies the left and right channel signals to your WL-Surround 

speakers. It also can feed the WL-RX SUB receiver (see below). Connect the WL-3TX as fol-

lows:

1. Connect RCA cables (not supplied) from the left and right output jacks on your home 

theater receiver or amplifier to the corresponding input jacks on the WL-3TX. If connecting a 

subwoofer via the WL-RX SUB, connect an RCA cable from the receiver’s subwoofer output 

jack to the subwoofer input jack (yellow) on the WL-3TX transmitter.

2. Set the channel selection switch (labeled “Wireless Channel”) on your speakers (and WL-

RX SUB receiver, if using) 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. You have 

the option of three channels.

3. Connect power to your WL-Surround speakers and the WL-3TX transmitter. The Status 

indicator on your speakers should illuminate and if using the WL-RX SUB, the receiver’s LED 

should change from red to blue. A blue light means the receivers are linked to the transmit-

ter and are ready for use.

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 transmit-

ter and subwoofer in the family room could be set to channel 1, while a wireless 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 adapt-

er. 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, indicat-

ing 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 transmitter. Make certain 

that your receiver/processor has the subwoofer function turned on in the setup menu.

•  INTERFERENCE, NOISE, INTERMITTENT OPERATION- Even though Phase Technology wire-

less products use advanced digital wireless technology, as with any wireless product the 

possibility of interference or noise reception does exist. Problems with interference, 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.
