WLT-02
WLR-02

Wireless stereo 2.4 GHz, 30 channel system
Installation Instructions v1.0

Warning: To be installed and/or used in accordance with appropriate

electrical codes and regulations.

Description: The WLT-02 transmitter and WLR-02 receiver are state of
the art, feature packed stereo wireless transmission systems. This
system boasts a 64k sampling rate (higher than CD’s 44.1k quality) and

2.4 GHz transmission. When multiple stereo transmissions are required,
up to 30 WLT/WLR’s can operate at the same time, in the same space
without sound quality or overlap issues. The WLT/WLR system can go

thorough most walls and be reliable up to 100’ (30 m) and 150’ (45 m)

outdoor line of sight. The shorter the transmission distance, the more

reliable it will be. Transmitter remote control included.

 Small size, fits almost anywhere!
 Up to 30 different stereo channels can operate in the

same space at the same time.

 Transmission distances up to 100’ (30 m)
 Super high quality due to 64k sampling rate with a latency

of less than 0.5 msec.

 Transmitter remote control included.

Installation:

The maximum transmission distance can vary depending on
several factors, including how much WI-FI traffic is taking place in
the space at any given time and how much iron and steel is
nearby. The rule of thumb is a maximum of 100’ (30 m) through
walls and 150’ (45 m) outdoor in direct line of sight. In certain
instances this system will encounter so much interference it may
not work at all. We always suggest experimenting to see if it will
work satisfactorily.

Connect the Knoll WLR-02 to a stereo amplifier with the included

3.5mm to RCA jack cord or plug it directly into headphones. Plug
the 5 VDC power supply into the power outlet with the WLR-02
power switch in the off position.

Connect the WLT-02 transmitter to the stereo source using the
supplied RCA to 3.5mm stereo cord provided or another cord. Plug
the 3.5 mm stereo jack into the WLT-02 jack labeled AUDIO. Plug
the 5 VDC power supply into the power outlet with the WLT-02
power switch in the off (left) position.

Operation:

Turn the stereo source music (iPod, CD player, stereo receiver
etc.) on to a mid comfortable volume setting if it has a control.
Move the switch on the rear of transmitter two clicks right to the
ON position. Turn the WLR-02 receiver power switch to the on
position. If this transmitter is the only one in the area, change the
transmitter using the remote or the WLT-02 CHANNEL SELECT
push buttons to channel 25.

In most stand alone systems we suggest starting with channel 25,
as this is at the high end of the WI-FI band and is generally less
used by other WI-FI users. If a great deal of interference is

detected this system is designed to temporarily mute or “dip out”.

If this happens repeatedly, try experimenting with other channels.

Turn the WLT-02 volume using the pushbuttons or remote control
until it is mid way (about level 16 of 32). Make sure the WLT-02
gain set switch is in the left MUSIC position. Turn the WLR-02
receive volume up to about level 16 of 32. Next change the WLR­02 channels to the same as the transmitter, channel 25. You
should now be able to hear the source. Adjust the volume to a
comfortable level and enjoy. Try experimenting with the
transmitter and receiver volume settings until the best quality
sound is produced.
