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 WRA-50 amplifier to the stereo speakers with 14-18 gauge wires. Plug the 14 VDC power supply into the power outlet with the WRA-50 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 3.6-6 VDC power supply into the power outlet with the WLT- 02 power switch in the off (left) position.

Operation:

Fig. 1 WRA-50 AMPLIFIER

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 WRA-50 amplifier 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 WRA-50 amp volume up to about 1/3. Next push the WRA-50 CH+ button slowly to change channels until the correct channel is chosen and you can hear the source. Adjust the volume to a comfortable level and enjoy. Try experimenting with the transmitter and amplifier volume settings until the best quality sound is produced.
