Introduction
Created specifically for performing and recording musicians who demand to be untethered
without compromising their sound, the XDS-PLUS 24-bit digital wireless system delivers
your tone and performance with the sound and feel of a direct wire connection all with extended range and added protection from outside RF interference.
X2’s proprietary digital technology provides superior fidelity while the XDR2 stomp-box receiver houses
a micro-processor that selects the digital data stream from among the two internal receivers to eliminate
dropouts and interference including DTV and other digital signal sources. You’ll enjoy the sound and
performance of a direct wire connection free from compander ICs - and the associated ’pumping’ and
’breathing’ - that squash your tone, as well as other problems associated with analog wireless
technology. Operating the system is unlike any wireless you’ve tried before. Simply connect the transmitter to the source via the 1/8" threaded-collar locking connector and the stomp-box receiver to your
amplifier or effects pedals. Then power up making sure the transmitter and receiver are set to the same
channel. That’s it. You’re ready to go! No knobs to adjust and no complicated menus to scroll through
mean you’re up and running in the time it would take to connect a cable.

Power Button
Press once to turn the unit on. Press again to turn the unit off.
Channel Up & Down Buttons
Press the UP button to select the next channel. Press the DOWN button to select the previous channel.
Button sequence does not wrap around. For example, once CH5 is selected you must press the DOWN
button four times to reach CH1.
Channel LEDs
A blue LED will light indicating the currently selected channel of operation.
Audio LEDs
Blue LEDs will light indicating the audio signal level. There is no need for a CLIP indicator as the system
has greater than 118 dB dynamic range and can accommodate input/output signals up to ~6V peak-to-
peak.
Battery LEDs
Green LEDs will light indicating remaining battery life in the transmitter in 20 minute increments. The first
three LEDs will glow red once the transmitter battery life falls below one hour. NOTE: Battery telemetry
is only available with XDT4 transmitters.
RF LED
A red LED will light indicating that an RF signal is present on the currently selected channel.
Receiver LEDs
A green LED will light indicating that the unit is receiving data on one of two internal receivers. The unit
houses two separate internal receivers. RX 1 represents the lower frequency while RX 2 represents the
upper frequency. Please see Frequency Diversity description page at the end of this manual.

Mode LED
A green LED will light indicating XDS+ mode (factory) and ensures that your system is operating at full
bandwidth and providing frequency diversity interference protection. A red LED will light indicating that
the receiver is currently operating in XDS mode allowing operation with original XDT1 transmitters (nonfrequency diversity).
NOTE: While in this mode, the frequency response will be (10 Hz - 12 kHz).
NOTE: Battery telemetry will be disabled when using XDT1 transmitters with XDR2.
Changing Receiver Operating Mode
To change the operating mode: power the unit off, press and hold the Channel DOWN button (left button) and power up. The unit will remain in the newly chosen and displayed mode until you repeat this
process.
