Quickstart
In order for the XPDm Digital Wireless System to work correctly, both the RXD1m
receiver and HXD1 handheld or PXD1 beltpack transmitter must be paired together.
(NOTE: The XPDm Digital Wireless System will come paired from the factory).
Follow this basic procedure for setting up and using your XPDm Digital Wireless
System:
1. Physically place the RXD1m receiver where it will be used. We suggest you keep
receiver and transmitter within line of sight for optimal performance, meaning
the performer using or wearing the transmitter can see the receiver.
2. Connect the included power adapter to the RXD1m receiver before turning the
power on. Turn the RXD1m on momentarily to confirm that it is receiving power,
then turn it off (figure 1).
3. With your amplifier or mixer powered off and
volume control down connect the RXD1m
receiver output jack to the mic or line input
using the balanced XLR output, unbalanced
1/4” or 1/8” output jacks. Turn the RXD1m
power on but keep the volume at minimum
level (figure 2).
4. Place a fresh set of AA (LR6) batteries in the
transmitter’s battery compartment being sure to observe polarity markings (figure
3).

Quickstart Continued
5. If the receiver and transmitter have not been previously paired press and hold
the pair button on the RXD1m receiver for >3 seconds until the LED begins to
flash (amber). Press and continue to hold the power button on the transmitter
until the LED indicators on both units light steadily indicating that the receiver
and transmitter are paired and ready for operation.(figure 4)
6. Turn on the connected amplifier or mixer but leave the PA system’s volume at
the minimum level. Turn the volume control of your RXD1m fully clockwise, this
is unity gain. Speak or sing into the microphone at a normal performance level
while turning up the PA system’s volume control until you reach the desired
output level.
7. NOTE: Only two XPDm systems can be used within close proximity to each other.

Troubleshooting
Issue Solutions
Make sure that the transmitter and receiver are both powered on.
Ensure the transmitter’s batteries are installed correctly.
Check that the transmitter is not muted.
Confirm that the RXD1m adapter is correctly connected and
plugged into an electrical outlet.
No Audio
Distorted Audio
Audio Dropout
Receiver will not power on Check the adaptor to ensure it is properly connected and plugged
Transmitter will not power
on (LED does not light)
Noise or interference If using two systems, make sure both systems are paired together.
Turn on the RXD1m receiver.
Make sure the RXD1m audio output connections are securely
seated into the jacks and that the cables are functioning.
Ensure that the receiver and transmitter are in line of sight with
one another.
Check the receiver and audio input device level controls.
Ensure that the transmitter and receiver are paired. If unsure,
follow the pairing explanation on page 11, #5.
The receiver output level or audio input device level may be too
high.
Check the transmitter’s batteries, and replace if low.
The input gain on the transmitter (PXD1/HXD1) or audio source
output level may be too high.
The transmitter may be too far away from the receiver. Move it
closer to the receiver.
Remove any sources that may cause RF interference such as cell
phones, cordless phones, lighting equipment, computers, metal
structures, etc.
into an outlet providing power.
Replace the transmitter batteries.
If the problem persists, pair each system individually.
