XPD2 USB Digital Wireless System 7
1.  Plug the RXD2 USB receiver into the USB jack on a wireless-enabled 
Samson audio device, or to an available USB port on a computer. 
Note: When using the XPD2 wireless system with a computer, you 
must set the computer’s audio input device to “Samson RXD Wireless 
Receiver”. In most computer operating systems, an audio software 
must be used to record or monitor the audio from the USB receiver. 
2.  Place a fresh set of AA (LR6) batteries in the transmitter battery 
holder, taking care to observe the polarity markings.
3.  If using a Samson audio device, turn the wireless level knob on the 
audio device completely counterclockwise, then turn the power of the 
audio device to the ON position.
4.  Turn on the power to the transmitter by pressing and holding Power 
switch; the indicator LED will light amber.
5.  If the transmitter and receiver have not been previously paired, press 
and hold the button on the RXD2 receiver for >5 seconds, until it 
begins to flash. Press and continue to hold the Power button on 
the transmitter until the LED indicators on both units light steady, 
indicating that the receiver and transmitter are paired and ready for 
operation. 
6.  Speak or sing into the microphone at a normal performance level and 
raise the input level on the audio device until the desired level is 
reached. For best signal-to-noise operation, set the input Gain control 
as high as possible without overloading.
7.  If you hear distortion turn down the input level on the audio device. 
If distortion is still audible, use the supplied screwdriver to turn the 
Gain control in the PXD1 transmitter slowly counterclockwise until the 
distortion disappears. 
Conversely, if you hear a weak, noisy signal at the desired volume 
level and with the wireless level control of the audio device is set to 
maximum, use the screwdriver to turn the Gain control in the PXD1 
transmitter slowly clockwise until the signal reaches an acceptable 
level.
