Product Overview & Features

The JLINK TRX system uses state-of-the-art wireless technology to send audio signals up to 100 feet away (30 meters). Broadcasting at an ultrahigh frequency of 2.4 GHz, the JLINK TRX delivers crystal-clear, stereo sound anywhere throughout your home.

Up to 3 JLINK transmitters can be used concurrently (3 output channels to choose from)
JLINK receiver includes JLINK port for compatible JL Audio products
Low-Power Sleep mode after 30 minutes of inactivity

Placement Considerations

The transmitter and receiver modules may be situated in any position, however their placement should be away from heat generating sources, such as amplifier or receiver heat sinks. Also ensure that each module’s placement does not interfere with the ventilation of other components.

Although mounting is not necessary, you may use the supplied hook & loop fastener tape to affix the modules to a flat surface on a cabinet wall, rack or component. If you choose not to mount the modules, make sure they are placed on a flat, stable surface to prevent damage from falling.

Connecting the Transmitter

Select the source device that you wish to transmit audio signal from and power OFF that device.
Connect the JLINK transmitter’s RCA line inputs to your source device’s RCA line outputs.
Plug the smaller end of the AC power adaptor into the transmitter’s power jack. Plug the larger end of the AC power adaptor into a standard A/C wall outlet.
Using the bottom-mounted switch, select one of three output channels to broadcast your audio signal. Note: The transmitter and receiver need to be set to the same channel.

Connecting the Receiver – Option A

(when using RCA connections)

Select the device that you wish to send the audio signal to and power OFF that device.
Connect the JLINK receiver’s RCA line outputs to your device’s RCA line inputs.
Plug the smaller end of the AC power adaptor into the receiver’s power jack. Plug the larger end of the AC power adaptor into a standard A/C wall outlet.
Set the receiver’s bottom-mounted switch to the same channel as the transmitter.

Connecting the Receiver – Option B

(when using JLINK port)

Select the JLINK compatible device that you wish to send the audio signal to and power OFF that device.
Set the receiver’s bottom-mounted switch to the same channel as the transmitter.
Plug one end of the supplied cable into the JLINK receiver’s JLINK port. Plug the other end of the cable into the JLINK port of the compatible device. The JLINK receiver will transfer its audio signal and receive its power connection directly through this cable. Note:
When connected in this manner, the JLINK receiver’s AC power jack and RCA output connections should NOT be used.
