Bodypack Transmitter ControlsFIGURE 11Power ButtonPress once to turn the unit on. Press and hold to turn the unit off. Channel Select ButtonPress 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 corresponding transmitter in order to operate correctly.LED DisplayA 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 signals up to ~6V peak-to-peak.Operating Modes for the TransmitterThe XDT4 ships in XDS+ mode from the factory and ensures that your system is operating at full bandwidth (10 - 20,000 Hz) while pro-viding frequency diversity interference protection (you can be certain that the transmitter is operating in XDS+ mode if the audio level LEDs are lighting up in blue when signal is present). If required, the XDT4 can operate in standard XDS mode. This is necessary when using it with the original XDR1 receiver or other X2 receivers that are operating in standard XDS mode (you can confirm that the trans-mitter is operating in standard XDS mode if the audio level LEDs are lighting up in red when signal is present). NOTE: While in standard XDS mode, the frequency response will be 10 - 12,000 Hz and frequency diversity (anti-jam) will be disabled.NOTE: Battery telemetry will be disabled when using original XDT1 transmitters with XDR2.9

Changing Transmitter Operating ModeTo 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.FIGURE 1210

To do so, remove the clip and remount it reversing the orientation as shown in figure 17.For thinner nylon-type guitar straps you can secure the transmitter by weaving the strap through the clip as shown in figure 18 or by running it straight up and down as in figure 19.13FIGURE 16 FIGURE 17FIGURE 18FIGURE 19

TroubleshootingIssueCauseSee Solution...No sound.System not turned on. Source malfunction. Im-proper connection or improper channel selection. Expired battery.Power, Signal Source, Cables or RFIntermittent sound or distorted sound.Source malfunction. Improper connection. Multipletransmitters are set to the same operating channel.Transmitter has gone out of range. Transmittingthrough metal wall. Unknown source of RF in localarea.Signal Source, Cables or RFLack of range.Improper or lack of antenna connection. Multipletransmitters are set to the same operating channel.Unknown source of RF in local area.RFPowerMake 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 SourceMake 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.CablesMake certain that all connections and cables are in working order.RFTurn 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 anX2 transmitter. Change the channel and repeat these steps to locate a clear channel.14

Optimizing PerformanceRF InterferenceAn X2 Digital transmission is not susceptible to interference in the traditional ‘analog’ wireless sense. An X2 receiver will only pass digi-tal 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 no-ticeable 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 chan-nel. Due to the anti-interference/anti-jamming technology available with the XDR-95 system, the chance of having a performance nega-tively impacted by RF interference is greatly reduced.Increasing RangeTransmission 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, comput-ers, digital effects, network switches, network cables, etc.). We recommend that you employ remote antennas when the receiver posi-tion 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 OperationFor 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 re-ceiving antenna that are connected to systems other than your system.15

Q-DiversityPLUS™ Frequency Diversity TechnologyWhat is it?A dual-frequency broadcast system that maximizes data isolation from undesired interference. It can also be thought of as twocompletely separate ‘true-diversity’ systems operating in tandem. RX 1 and 4 work together to receive the lower frequency whileRX 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 usersrequiring 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 modulatedon two separate RF carrier frequencies. The receiver contains a quadraplex of separate receiver sections that work simultaneouslyto receive the two RF signals. Two receiver sections are directly connected to two internal antennae, while two others arefed RF signals via two chassis mounted BNC connectors. These sections work simultaneously to receive the two RF signalsthat 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 ofincreased interference and longevity of performance in the field.FIGURE 2019
