Description:  The Wireless Audio Transmitter by Q Wireless will broadcast a monaural audio signal wirelessly through 
the air to a compatible receiving device.  There are six independent RF channels in the 900 MHz band for frequency 
diversity and the unit is powered from an external DC wall mount power supply. 
 
Setup: 
 

1)     Connect one end of a shielded audio cable to the audio output of your music source.  Please note that the RCA 

audio cable must be shielded. 

 

2)     Connect the other end of the cable to the Audio Input Jack on the Wireless Audio Transmitter.  

 

3)     Plug the external DC power supply into an available and working wall AC outlet. 

 

4)     Connect the 2.5 mm power connector into the Wireless Audio Transmitter’s power jack.  The green POWER 

ON / CHANNEL indicator will glow ON if power is supplied to the unit. 

 
Changing the RF Channel: 
 

1)     The Wireless Transmitter comes from the factory preset to CHANNEL #1.  This can be confirmed by re -

connecting the power supply into the unit and by counting the number of flashes seen on the green LED 
indicator.  One flash – CHANNEL #1, two flashes, CHANNEL #2, etc.  

 

2)     To change to the next available RF channel, depress the channel switch once.  You will know that the new 

channel has been entered properly when the green LED indicator starts flashing.  Again, One flash – CHANNEL 
#1, two flashes, CHANNEL #2, etc. 

 

3)     Repeat step #2 until the desired channel is obtained.  Once CHANNEL #6 has been reached, the next depression 

of the CHANNEL SWITCH will return the channel back to CHANNEL #1  

 

4)     Once the channel has been set, it will be stored in non-volatile memory.  The Transmitter will default to the last 

channel programmed on power up.
