Introduction to the XDR-95 Digital UHF Wireless
Created specifically for performing and recording musicians who demand to be untethered
without compromising their sound, the XDR-95 24-bit digital wireless system delivers your
tone and performance with the sound and feel of a direct wire connection.
X2’s proprietary digital technology provides superior fidelity while the XDR-95’s receiver houses a micro-processor that selects the
digital data stream from among the four 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 rack-mount receiver to your amplifier or mixer. 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 antennas to loose or break mean you’re up and
running in the time it would take to connect a cable. For maximum performance range, attach the included 1/2 wave antenna or
optionally remote mount standard paddle antenna for even greater flexibility and range.

CH1.
Channel LEDs. A blue LED will light indicating the currently selected channel of operation.
RF LED. A red LED will light indicating that an RF signal is present on the currently selected channel.
Mode LED. A red LED will light indicating that they receiver is currently operating in a backwards compatible mode to allow operation
with original XDT1 transmitters. Please note that while in this mode, the frequency response of the system is that of the original XDR1
receiver (10 Hz - 12 kHz). To enter this mode, power the unit off, press and hold the Channel DOWN button and power up. The unit will
remain in this mode until the power is cycled off then on again.
Receiver LEDs. A green LED will light indicating that the unit is receiving data on one of four internal receivers. The unit houses four
separate internal receivers, two of which include internal antenna meaning that the system will operate even without external antenna
attached. *Please note that range may be adversely affected without attaching the supplied 1/2 wave antenna.
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 (approximately).

Transmitter Controls and Connectors
Power button. Press once to turn the unit on. Press again to turn the unit off.
Channel Select button. Press the CH SEL button to select the next channel. Button sequence will wrap around. For example, once
CH5 is selected you must press the CH SEL button one time to reach CH1. Receiver must be set to the same channel as the corre-
sponding transmitter in order to operate correctly.
LED Display. A blue LED will light indicating the currently selected channel of operation and a
red LED indicates remaining battery life
in one hour increments. When idle, these LEDs toggle continuously. During performance, blue LEDs indicate input 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 (approximately).
Threaded Sleeve. Secure the 1/8” jack plug in place by screwing down the threaded sleeve onto the input jack socket threads and turn
approximately two times.
Jack Plug. For correct operation, the jack plug must be inserted all the way into the jack socket with the threaded sleeve securely
fastened to the threaded input jack socket.
Threaded Input Jack Socket. Make certain that a secure connection is made for trouble-free operation.
Instrument Input. The instrument input circuit is wired to the ring of the input jack plug and socket.
Microphone Input. The microphone input circuit is wired to the tip of the input jack plug and socket.
Battery Life. Fresh Alkaline batteries should last about ~6 hours in the XDT4. NiCad rechargeable batteries will only last about 3.5
hours. Standard batteries are not recommended. THE BATTERY HOUR DISPLAY WILL ONLY BE ACCURATE FOR ALKALINE
BATTERIES. The battery life is calculated inside the each component and displayed in 1 hour increments. Upon power up the battery
info will take about one minute to stabilize, the battery gauge is then accurate within + or - 15 min. You may use batteries until they are
completely drained without affecting the performance of the unit in any way.
Operation note: the system operates at unity gain meaning that the signal fed to the transmitter is produced identically at the receiver.
Therefore, there are no knobs to adjust or switches to change in order to achieve optimum signal levels.

Troubleshooting
Power
Make certain that the transmitter and receiver are receiving sufficient power. The receiver requires 9V DC at 500 MA. The transmitter
requires 9V DC via alkaline 9V battery. Check the battery status indicator on the transmitter and replace if necessary.
Signal Source
Make certain that the source is operating as desired by checking source power, signal levels and connections. If necessary, bypass
digital wireless transmission and check the source directly.
Cables
Make certain that all connections and cables are in working order.
RF
Turn all known transmitters off. Check to see if the red RF LED on the receiver’s front panel is lit. If it is not lit, then the receiver is not
detecting the presence of RF signal on the currently selected channel. If it is lit, then the receiver is detecting the presence of unknown
RF signal. Check to see if any of the green Receiver LEDs are lit. If any are lit, then the receiver is detecting the presence of another
X2 transmitter set to the same channel. Locate this unit and either turn it off or switch channels. If none of the green Receiver LEDs
are lit, then the receiver is detecting confirmed RF signal from a source other than an X2 transmitter. Change the channel and repeat
these steps to locate a clear channel.
Issue
No sound.
Intermittent sound or distorted sound.
Lack of range.
Cause
Source malfunction. Improper connection. Multiple
transmitters are set to the same operating channel.
Transmitter has gone out of range. Transmitting
through metal wall. Unknown source of RF in local
area.
Improper or lack of antenna connection. Multiple
transmitters are set to the same operating channel.
Unknown source of RF in local area..
System not turned on. Source malfunction. Improper
connection or improper channel selection. Expired
battery.

RF Overload
This will usually not cause a problem unless you are using more than one system at the same time, in which case, it can become a
factor when maximum performance range is desired. For example, one performer is ~200 feet from their receiver and another
performer comes within one foot of the furthest performers’ receiver causing the furthest performers‘ signal to mute temporarily. This
can be avoided with proper planning. In any case, the offending transmitter’s signal will not ‘come through’ the other performer’s
equipment.
RF Interference
An X2 Digital transmission is not susceptible to interference in the traditional ‘analog’ wireless sense. An X2 receiver is will only pass
digital data that originated from an X2 transmitter set to the same operating channel. If this transmitter has a custom encryption
scheme, a standard X2 receiver will no longer be able to recognize or reproduce the signal. RF interference for X2 systems will only
become noticeable when a system’s range has been adversely affected or when the red RF indicator is lit without the desired
transmitter in use. In most cases, the system will still operate with an acceptable performance range even when RF interference is
present on your channel. Due to the anti-interference/anti-jamming technology of the XDR-95 system, you will likely never have a
performance negatively impacted by RF interference.
Increasing Range
For best results, maintain a line of sight between transmitter and receiver antennas.
Move receiver antennas away from metal objects or other sources of RF interference (such as CD players, computers, digital effects,
network switches, network cables, etcetera).
For multiple systems, make certain that each system is operating on it’s own separate channel.
