Connect Wireless Transmitter to Audio Receiver

Use one of the following two setups to connect the wireless transmitter to receiver:

SETUP #1:
MOST COMMON
(RECEIVER LFE/SUB OUTPUT)
This setup requires one RCA cable.

1. Use one of the RCA cables supplied to connect the wireless transmitter's LFE input to your receiver's LFE or SUB output. Connect with one lead only.
2. Plug the wireless transmitter's 5V DC power adapter into the back of the wireless transmitter. Plug the other end of the adapter into a power outlet.
3. Go to the Select Receiver Options for Optimal Subwoofer Performance instructions next.

The WiConnect System receiver must be within 50 feet (15 meters) from its transmitter to be able to receive the wireless signal. Also, make sure that the same CHANNEL is selected on both the transmitter and receiver.

SETUP #2:
LESS COMMON
(NO RECEIVER LFE/SUB OUTPUT)
This setup requires one RCA cable for each of the L and R channels.

1. Use one of the RCA cables supplied to connect the wireless transmitter's R and L inputs to your receiver's R and L outputs.
2. Plug the wireless transmitter's 5V DC power adapter into the back of the wireless transmitter. Plug the other end of the adapter into a power outlet.
3. Go to the Select Receiver Options for Optimal Subwoofer Performance instructions next.

The WiConnect receiver must be within 50 feet (15 meters) from its transmitter to be able to receive the wireless signal. Also, make sure that the same CHANNEL is selected on both the transmitter and receiver.

Select Audio Receiver Options For Optimal Subwoofer Performance

It is important that the audio receiver is set up correctly to work in concert with the WiConnect System. To set up the audio receiver refer to its instruction manual and use one of the following three options:

AUDIO RECEIVER OPTION #1
The audio receiver's LFE or SUB output is the input to the subwoofer (most common case). Use the audio receiver's speaker menu and set as follows:

1. Select that you have a subwoofer.
2. Select the number of speakers.
3. Select the speaker size as SMALL.
4. If you don't know the low frequency limit of your main speakers, use 80 Hz as the crossover point. The lower limit of the main speaker's frequency response is usually listed in the speaker specifications as, for example, "3 dB down at 45 Hz." In this example, double the value (45 Hz) and use the doubled-value (90 Hz) as the crossover frequency.
5. Adjust the LFE /SUB output level to 0 dB.
6. Go to the Connect Subwoofer instructions next.

AUDIO RECEIVER OPTION #2
The audio receiver's unfiltered/full frequency range R and L output channels, not its LFE or SUB output, is the input to the WiConnect System (less common case). Use the audio receiver's speaker menu and set as follows:

1. Select that you have NO subwoofer.
2. Select the number of speakers.
3. Select the speaker size as LARGE.
4. If the crossover frequency option is available, double your main speakers specified low frequency response value and select the result as the crossover frequency. If you don't know the low frequency response value, use 80 Hz.
5. Go to the Connect Subwoofer instructions next.

AUDIO RECEIVER OPTION #3
The audio receiver has no LFE or SUB output:

1. No selections to make in the receiver's speaker menu.
2. Go to the Connect Subwoofer instructions next.

Connect Subwoofer

1. Place WiConnect System RF receiver near your subwoofer. Do not place in a metal cabinet — this may degrade reception performance.
2. Attach included 5V DC power adapter to WiConnect System receiver.
3. Attach the appropriate RCA cables, depending on the audio receiver option chosen between the WiConnect System receiver and your subwoofer.
4. Plug RF receiver or WiConnect System power adapter into wall outlet.
5. Turn the VOLUME knob to MIN to prevent blasting music when you first use the subwoofer. you can increase the VOLUME to the correct level later.
6. Turn on subwoofer.
7. You're done. No more wires to connect!
8. 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, or if you plan to use more than one WiConnect System (only up to four total WiConnect Systems can be used within 50 feet of each other).
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 wireless receiver to select the same broadcast channel as you selected on the wireless transmitter.

Wireless Broadcast Considerations

All wireless devices like the WiConnect System may be susceptible to radio frequency (RF) interference from other devices, depending on frequency used. 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 wireless receiver.
To prevent wireless broadcast interference problems, keep wireless transmitters at least 2' apart. Any interference effects 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 WiConnect System and the microwave oven.
If the WiConnect System sound is intermittent, check that another wireless device isn't within 2' of either the wireless transmitter or the wireless receiver. Also, try one of the other broadcast channels of the WiConnect System as it may be free of the RF interference.

Connect Multiple Wireless Subwoofers

In a Single Audio System

If you are using more than one WiConnect System in a single audio system, or in two audio systems close together, 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 audio 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 Audio Receiver Options for Optimal Subwoofer Performance section.
3. Set the same wireless broadcast channel on the wireless transmitter and all RF receivers. Follow the instructions in the Select Wireless Broadcast Channel section.

OPTION #2: Subwoofers receive different 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, or for two differently purposed audio systems on either side of a wall. 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 receiver. 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 Audio Receiver Options for Optimal Subwoofer Performance section.
3. Follow the instructions in the Select Wireless Broadcast Channel section, except:
   1. Select a unique wireless broadcast channel for each wireless transmitter.
   2. Match the wireless broadcast channel on each WiConnect receiver to that of the WiConnect transmitter that broadcasts the audiosignal that WiConnect receiver 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 office, you can use a separate wireless transmitter in each system. In this case, use a different wireless broadcast channel for each system, to avoid the subwoofers from getting input from multiple systems due to the close proximity of the systems.

Mount Wireless Transmitter or Receiver on Wall (Optional)

Optionally, you can mount the wireless transmitter or receiver on the wall or place in a location that better organizes your audio components. The WiConnect System 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.

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.

MAINTAIN

Protect Transmitter and Receiver from Damage

DO NOT PUT OBJECTS ON TOP of the transmitter or receiver case that could scratch or otherwise damage the case.

DO NOT EXPOSE TRANSMITTER OR RECEIVER TO DRIPPING OR SPLASHING FROM LIQUIDS.
DO NOT PLACE LIQUID-FILLED OBJECTS ON OR NEAR THE TRANSMITTER OR RECEIVER. Examples of liquid-filled objects include flower vases, beverages and liquid-fueled lamps.
DO NOT PUSH OBJECTS OF ANY KIND into the transmitter or receiver openings.
DO NOT PLACE BURNING CANDLES, INCENSE, OR SMOKING PRODUCTS ON TOP OF OR NEAR THE TRANSMITTER OR RECEIVER.

Clean

USE A CLEAN, SOFT DAMP CLOTH to remove dust or fingerprints from the transmitter or receiver case. Unplug the power cord from the power outlet before cleaning to prevent static electricity from damaging the transmitter or receiver during cleaning.
DO NOT CLEAN THE WIRELESS TRANSMITTER OR RECEIVER CASE with detergents, soaps, abrasives, aerosol sprays, chemical solvents, alcohol, or other cleaning solutions.

Service

DO NOT ATTEMPT TO SERVICE THE WIRELESS TRANSMITTER OR RECEIVER YOURSELF beyond what is described in this owner's manual.
ONLY USE QUALIFIED SERVICE TECHNICIANS TO REPAIR DAMAGED PARTS. Service the transmitter or receiver using qualified service technicians when:

• A power cord or plug is damaged
• The power socket on the transmitter or receiver is damaged
• Objects have fallen on, or liquid has spilled into the transmitter or receiver
• The transmitter or receiver was rained on or has become partially or fully submerged in water
• The transmitter or receiver does not operate normally or exhibits a marked change in performance• The transmitter and receiver has been dropped or is damaged

Troubleshoot

THE TRANSMITTER OR RECEIVER LED IS NOT LIT:

1. Verify that the power adapter is plugged into a live power outlet.
2. Verify that the power adapter is not damaged.

IF YOUR SUBWOOFER ISN'T PRODUCING SOUND, BUT THE TRANSMITTER ACTIVE LIGHT IS BLUE AND THE RECEIVER LIGHT IS SOLID GREEN:

1. Verify that the wireless transmitter is plugged into a live power outlet. The receiver's green LED will blink if it does not receive the transmitter's signal.
2. Verify that the wireless transmitter's inputs are connected to the audio receiver's output. This wire may have become accidentally disconnected.
3. Increase the subwoofer's VOLUME level.
4. Increase the receiver's LFE or SUB OUT volume level, if it is adjustable.
5. If your receiver has a switch or menu to enable its LFE or SUB OUT, make sure this switch or menu is set to ON or YES.
6. Verify that the wireless transmitter's light is on solid. If the transmitter's light isn't on solid and the same CHANNEL is selected on both the wireless transmitter and receiver, select another matching CHANNEL for the wireless transmitter and receiver.

IF THE BASS DOESN'T SOUND LOUD ENOUGH TO YOU:

1. Increase the subwoofer's VOLUME level.
2. Increase the receiver's LFE or SUB OUT volume level, if it is adjustable.
3. Put the subwoofer closer to a corner of your room.

OR

The transmitter and receiver may have lost their broadcast connection.

1. Turn off power to the subwoofer, wireless transmitter, and wireless receiver.
2. Turn back on power to the wireless transmitter, then the wireless receiver, and then the subwoofer.
3. If cycling the power doesn't re-establish the broadcast connection, select another matching CHANNEL for the wireless transmitter and receiver.
4. If selecting another CHANNEL doesn't re-establish the broadcast connection, decrease the distance between the wireless receiver and the wireless transmitter to increase the broadcast signal strength between them.
5. Verify that the transmitter and wireless receiver aren't in close proximity to other electronic devices that could interfere with the wireless transmission and reception.

Specifications

A Note on bandwidth:
Although this manual is written from the perspective of wireless signal transmission for subwoofers, you will see when reviewing the specifications that the WiConnect System has a very wide bandwidth (20-16k Hz +/- 0.5 dB). Thus, it could be used in some cases for full range signals as well.
