Thank you for your purchase of the XD-V75 Digital Wireless microphone system. It is a sophisticated digital wireless system, yet is easy to configure and use within minutes. With its fully digital transmission, the system provides features and benefits that differ in some ways from previous generations of analog wireless, but in most respects you use it just like other wireless systems.
Recommendations for Best Performance • Maintain a clear line of sight between the transmitter and receiver antennas. Typically the receiver antennas should be above head level. Avoid placing the receiver in the bottom of the rack unless remote antennas are employed. • Avoid placing the receiver behind walls. When this is necessary the receiver’s antennas should be remotely located as to be in sight of the transmitter.

What Makes a Wireless Digital? In a typical analog wireless microphone system the signal between the transmitter and the receiver consists of a very high frequency radio wave carrier that is continually varied slightly in frequency by the audio signal from the microphone (or other transducer). The electronic circuitry in the receiver removes the carrier frequency and leaves the audio signal – the same principle that is used in FM radio broadcasts.
to a digital word of 1’s and 0’s, that information will be ignored. If noise is riding on those digital words, it is still decoded as one of two states – rather than something in-between, if it were analog. As long as the digitally modulated carrier arrives at the receiver’s antenna with sufficient level, it will be accurately decoded. And as with CD players and other digital audio devices, error concealment algorithms may be added to fill in the gaps where there is missing information.
THH12 Handheld Transmitter Detailed Setup To begin, twist the bottom section of the THH12 transmitter counterclockwise, unscrew and remove it. Lightly pull the battery cover tab down with a thumbnail, and open the cover by pulling back; it is hinged at the base of the transmitter. Insert two AA batteries, noting the polarity markings shown in the battery compartment. Note, Use alkaline batteries, or rechargeable NiMH batteries in the 2400 – 2800 mAh range.
Note, The transmitter can be locked so that the user cannot accidentally or deliberately make changes to its settings during use. To set the lock, unscrew the bottom section of the transmitter, go to the back side of the battery compartment, and flip the small micro-switch to the right to lock; the display will show the image of a lock in the lower left corner, and the word [LOCKED] will appear whenever a button is pushed. Replace the bottom section to use.
When the transmitter is on, a quick push and hold of the MUTE button will mute the audio, and the backlight will remain lit while it is muted. The word [MUTE] will appear on the display. Another quick push will un-mute it. The TBP12 transmitter has other editable functions, including high and low power modes, selectable microphone settings, encryption options, and the ability to give the transmitter a 6-character name that will show on both the transmitter and receiver displays.
Channel Scanning Procedure Though the Line 6 wireless microphone system operates in the unlicensed 2.4 GHz band – above the frequencies used by most wireless microphone systems, cellular phones, and other voice communication devices – the band is not unused, and does include WiFi routers.
Note: Make sure all powered on Line6 TX units are a minimum of 2 meters away from scanning RX antennas. This will avoid overload and incorrect scanning function while in this mode. Audio Output & Filter Adjustments Receiver Output Level Adjustments The default receiver output from the XD-V75 receiver is +0 dB or unity gain. This allows the wireless unit to use the same mixer gain levels as the equivalent wired microphone, and connect to the mic-level input of the mixer.
Dynamic Filter Adjustments The dynamic filter allows users to select from [OFF] (no filtering), [NORM] (for music applications), and [TALK] (for spoken word applications). When active, the filter minimizes handling noise and stage vibrations, via a downward expander with a dynamic high-pass filter. In the [NORM] mode, when the microphone input level falls below a fixed threshold, overall level is reduced by approximately 6 dB while simultaneously rolling off frequencies below 200 Hz.

Microphone Usage Tips Unlike a handheld microphone where the user typically speaks or sings directly into the mic element – where the full frequency response of both the person and the mic is available, lavalier microphones are placed on the body in a variety of places. Being farther away from and below or to the side of the mouth, the level is usually much lower, plus the frequency response lacks the highs as well as the lows from being near the mic element.
To name the transmitter, press and hold the SELECT button until it changes to the channel select page. Quickly press the SELECT button four more times until you reach the [NAME] page. The default position is [OFF]. Press the ON/MUTE button on the handheld or the VALUE button on the beltpack to select [ON]. Press the SELECT button, and the default name (or if already named, the transmitter’s name) appears with the first letter flashing.
lit. To mute the TBP12 beltpack, push and briefly hold the MUTE button on the top of the pack; press again to unmute. The display works identically to the handheld. When the mic is muted and you press the SELECT button to enter another parameter page, the word [MUTED] will remain in tiny characters in the left center of the display as a reminder. When a transmitter is [MUTED] the red MUTE LED will light on the receiver.
The transmitter automatically and randomly generates a six-digit hex code (characters 0 – 9 and A – F), which it uses for encryption and remembers even when the transmitter is turned off. The only way to “lose” this code is to turn the [CRYPTO] page to [OFF]. The code may be seen only once, by pressing the SELECT button immediately after setting [CRYPTO] to [ON]; it will appear on the backlit display for two minutes or until the SELECT button is pressed again to go to the next page.
Note, Though the direct transmission of the encryption code from the transmitter to the receiver is faster and secure, since it is done at very low power in close proximity to the receiver, some users may want to make sure that the code is never transmitted –thus the ability to enter it manually. Also, for redundancy, in some cases the user might want to have two receivers in place holding the same encryption code for the transmitter, with the second one as a backup.
to be charged internally. Because the transmitter’s battery meter was calibrated for alkaline batteries, they will not be as accurate in calculating the remaining battery life when using rechargeable batteries. Note, Carbon-zinc batteries are not recommended.
Since the XD-V75 transmitters use two frequencies simultaneously, the bars to the left of each letter represent the lower of the two frequencies, and the bars to the right of each letter the higher frequency. In some cases, only one of the two frequencies will show interference. The following chart describes the potential effect on performance.
at least a few feet away from the receivers when you are operating the wireless system. Minimizing Near / Far Transmitter Effects Line 6 digital wireless systems are designed so that a receiver only passes audio from a transmitter that is set to the same channel. While other nearby transmitters and RF sources will not create audio in a receiver not on their channel, under certain conditions they can have an effect on range.
To rack-mount a single XD-V75 receiver, use both the long and short rack ears provided with the receiver; the receiver can be mounted on either the left or right side of the rack. If you are not using optional remote antennas, you will be mounting the provided half-wave antennas on the long rack ear. Remove the rubber covers to expose the D-cut mounting holes in the rack ear, unthread the hex nut and lock washer from the provided BNC-to-BNC connectors, pass them through the holes, and rethread and tighten.
Note, For best performance, Line 6 recommends that no more than four receivers share a single pair of antennas via looping through the BNC ports on the rear of the receiver. For the next group of four receivers, use another pair of antennas. Alternately, use a Line 6 antenna distribution unit or other RF distribution unit that is appropriate to the 2.4 GHz band to run multiple receivers from one pair of antennas.
