Q-Audio QWM 1940 V2 systems uses16 UHF frequencies from 863.0 to 865.0 MHz.
Systems are available with handheld microphones or bodypack kits (including headset mic, lavalier/lapel mic and
guitar/instrument lead). If you have purchased theoptional QWM 1940BP V2 Kit, you will also need a Q-Audio
QWM1940 V2 receiver (not included in theQWM 1940 BP V2Kit) to operate and receive signals from your
bodypack.

Operation
Before operating the system ensure that you have installed fresh new batteries in the mic or bodypack transmitters.
Receiver operation
1. Connect audio outputs for channel Aand Bto your mixer/amplifier/PA speaker system, either two balanced XLR
cables for dual output or a single unbalanced 6.35mm jack cable for mixed output of both channels.
2. Turn down the receiver channel volume control knobs (2.)before wirelessly connecting your transmitters.
3. Connect the DCpower supply to thereceiver and plug into anappropriate power outlet.
Automatic transmitter connection to receiver (ACT)
1. Ensure that the microphone/bodypack is turned OFF and the receiver is turned ON.
2. Decide which of the 16 frequencies you wish channel Ato operate on. In this example we will choose the first
frequency (863MHz). On the receiver unit, press and hold thechannel selection button (5.) until the channel number
LEDs start flashing. Press the button again to move up through the frequencies until you reach your chosen
frequency (e.g. 1). Wait until the channel number LEDs stop flashing, this is now your selected frequency.

3. Slide off the battery compartment cover on the rear of your mic (by pushing downwards towards the base) or open
the bodypack battery compartment.
4. Now turn ON your mic/bodypack transmitter.
5. Ensure that there is a short and direct line-of-sight between the transmitter infrared connect window (14. on the
mic or 20. on the bodypack) and thereceiver’s infrared connect window (7.). In other words, point the open battery
compartment of the mic or bodypack towards themiddle of the receiver’s front window.
6. Press and hold the IR connect button on the receiver (6.), the infrared connect window’s LED indicator will flash
momentarily and then theRFLED indicator (4.) will light up green. The receiver and mic or bodypack are now
connected (channel A = frequency 1 /863MHz).
7. To test the connection, speak into themic, the AFLED indicator should light up orange to indicate that the unit is
receiving anaudio signal. To test the bodypack, attach one of the mics or an instrument to the bodypack input socket
(15.), turn up the volume control (18.) and speak or play, the AF LED indicator should light up orange to indicate that
the unit is receiving an audio signal.
Whenever the mic/bodypack transmitter or system are turned off and then turned on again, the ACT connection
should remain in place until you change the channel frequency on the receiver. This allows the mic/bodypack to be
turned on and off during performance. If for any reason the connection is lost, simply repeat from step 1.
To connect the second microphone/bodypack to Channel B, repeat the above procedure from step 1. (but choose a
different frequency in step 2.). To avoid interference between the two channels, ensure that your chosen
frequencies are not too close to each other (e.g. 1+2), instead choose two separated frequencies e.g. 1+14 or 5+15.
When both channels have transmitters connected, turn up the channel volume controls on the receiver and the
volume controls on your connected mixer/amplifier/PA speaker system, you should hear the signal coming through
and you can adjust the volumes to suit your performance.
VERY IMPORTANT - if you wish to run 2 receivers and 4 transmitters together and to avoid interference between
the two systems, it is recommended you use the following setup:
Unit 1 - set channel Ato frequency 1and set channel B to frequency 14.
Unit 2 - set channel Ato frequency 5and set channel B to frequency 15.
Troubleshooting
If you are having trouble connecting the mic/bodypack transmitters to the receiver, first check whether you have
fresh working batteries correctly installed. Weak or dead batteries will NOT be able to make a connection. If you still
fail to connect the two, start by turning both units OFF for 5 seconds, then turning the receiver only back on and
starting the connection procedure from step 1.
