WTA-PACK
50 Watt 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 WTA-PACK consists of a 50 watt WRA-50 amplifier and
a WLT-02 transmitter. 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 WTA-PACK’s can operate at the
same time, in the same space without sound quality or overlap issues.
Transmission distances can vary and should be tested. The WTA-PACK
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, HUGE sound. Fits almost anywhere!
Stereo amplifier has 25 watt RMS per channel rating.
Up to 30 different stereo channels can operate in the same space at the
same time.

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 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.
