Introduction
Created specifically for performing vocalists and musicians who demand to be untethered without compromising their sound, the XDR95x 24-bit digital wireless system delivers your exact 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 XDR-95x’s rack-mount 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 grab the microphone or connect the transmitter to the source via
the 1/8" threaded-collar locking connector, then connect the rackmount receiver to your amplifier or mixer. Finally, power up making
sure the transmitter and receiver are set to the same channel. That’s it. You’re ready to go! The XDR-95x is free of the typical setup
complications of other systems meaning you’re up and running in the time it would take to connect a cable. For greater operating range,
attach the included 1/2 wave antenna to the BNC connectors on the back panel of the receiver. And for even greater flexibility, the system ships complete with a front-mount antenna kit that allows you to bring the BNC connectors and antenna out to the front of the receiver unit.

Power
Make certain that the transmitter and receiver are receiving sufficient power. The receiver requires 9V DC at 500mA. The handheld
transmitter required 3V DC via two alkaline AA batteries. The bodypack 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.

Optimizing Performance
RF Interference
An X2 Digital transmission is not susceptible to interference in the traditional ‘analog’ wireless sense. An X2 receiver 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 reliably with a reduced performance range even when RF interference is present on your channel. Due to the anti-interference/anti-jamming technology available with the XDR-95 system, the chance of having a performance negatively impacted by RF interference is greatly reduced.
Increasing Range
Transmission range depends to a large extent on location and can vary the minimum and maximum performance range. There should
be a “free line of sight” between transmitters and receiving antennas. 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, etc.). We recommend that you employ remote antennas when the receiver position is not the best antenna position for optimum reception. For multiple systems, make certain that each system is operating on it’s own
separate channel.
Multi-channel Operation
For multi-channel operation, it is recommended that you only use channels that are not in use by other performers. Before powering on
additional transmitters, we recommend performing a quick RF scan. This is done at the receiver unit by selecting unused channels and
checking for the presence of RF energy via the RF indicator on the front panel. If the channel is open, power on the desired transmitter
and set it to the open channel. NOTE: When operating more than one system, maintain a minimum distance of 3 ft. from all other receiving antenna that are connected to systems other than your system.

Q-DiversityPLUS™ Frequency Diversity Technology
What is it?
A dual-frequency broadcast system that maximizes data isolation from undesired interference. It can also be thought of as two
completely separate ‘true-diversity’ systems operating in tandem. RX 1 and 4 work together to receive the lower frequency while
RX 2 and 3 work together to receive the upper frequency.
What does it do?
Allows XDR95 to provide reliable performance under adverse RF conditions.
Do other types of technology use dual-frequency broadcast?
Multiple frequency broadcasts are not unique. OFDM would be an example of splitting up data over multiple frequencies.
However, X2’s proprietary Q-DiversityPLUS is unique for real-time audio applications.
Why do we need it?
Wireless systems are subject to increased interference due to known and unknown sources of RF interference, including DTV,
cell phones, blackberrys and networking devices. XDR95 was designed to address the needs of professional wireless users
requiring consistent reliable performance even in adverse conditions without any loss to sound quality.
How does it work?
In the transmitter, a proprietary digital data stream that includes a digital representation of the audio signal is split and modulated
on two separate RF carrier frequencies. The receiver contains a quadraplex of separate receiver sections that work simultaneously
to receive the two RF signals. Two receiver sections are directly connected to two internal antennae, while two others are
fed RF signals via two chassis mounted BNC connectors. These sections work simultaneously to receive the two RF signals
that contain the transmitted digital data.
Why is it better?
Q-DiversityPLUS allows the XDR95 to exceed other wireless systems in terms of freedom from negative audio side-effects of
increased interference and longevity of performance in the field.
