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.
•Avoid placing the receiver in close proximity to RF generating equipment including computers, wireless access points and microwave ovens.
•Point the antennas up and 45 degrees from vertical while avoiding touching metal objects like rack or rack rails.
•Avoid blocking antennas in the transmitters. Do not “cup” the bottom of the handheld transmitter. Avoid placing the beltpack transmitter in pockets.

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. The signal is highly compressed upon transmission and expanded at the receiver – the origin of the word “companding.” Analog transmissions are vulnerable to many interference effects from other RF and electromagnetic signals – and the interference is usually audible as well as having the effect of shortening range or rendering the channel unusable.

Digital wireless microphone systems provide a much more robust and interference resistant performance. Within the microphone transmitter, the audio signal from the voice or other source is digitally sampled, and the sample is converted into a digital “word” consisting of the electrical equivalent of a string of 1’s and 0’s. As in analog wireless, a very high frequency carrier wave is modulated, but in this case with the digital “stream” of samples so that the carrier frequency only has two distinct states that represent the signal in the same manner that the flat areas and pits on a CD represent the music. The receiver retrieves this information from the carrier and decodes it via a D/A converter and outputs an audio signal that is the replica of what was encoded at the mic.

Benefits of Digital Wireless
As mentioned above, analog wireless transmissions are susceptible to a variety of noise and interference conditions, related to signal strength and/or interference from external electronic devices and other wireless signals. These can ride along with the carrier frequency and its audio signal as added noise, affect the receiver directly because the antennas that pick up the transmitter signal are also wide open to pick up other radio signal in the same general RF band, or interact with the carrier frequency to create additional harmonic frequencies. Problems can come from sources as diverse as a television broadcast signal, other wireless mics in use, digital signal processors, or even malfunctioning fluorescent lighting ballasts or other electrical devices.
While the same physics applies to a digital signal riding on a carrier wave, the digital signal with just two states is more difficult to damage. If the receiver finds that something has come in that is not equivalent
9
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.
Typically with a digital wireless system, the signal will retain its quality until the signal level is too low, and then it’s gone. The main effect that interference has on a digital wireless system is that it will shorten the maximum range between the transmitter and receiver antenna. To alleviate potential problems, maintain line-of-sight between transmitter and receiver, locate the receiver / receiver antennas at a distance from interfering sources such as WiFi routers, and use the HI setting on the transmitter when operating at longer distances.
XD-V75 Receiver Detailed Setup
For stand-alone placement, position the receiver on a level surface where the front-panel controls and displays are visible. Connect the supplied DC-1G power supply to the 9VDC In connector on the rear panel; to secure, press a loop of the cable through the cable holder located above the connector to prevent accidental disconnection. Plug the power supply into an available AC outlet that provides voltage from 90 – 240 VAC.
Place the supplied half-wave articulating antennas (RDrac) on to the outer left and right BNC connectors marked ANTENNA A and ANTENNA B. Rotate a quarter-turn clockwise, and then position the antennas at an approximately 45 degree “rabbit ears” orientation. For details on frontmounting antennas when rack-mounting, or connecting multiple receivers, see Antenna Mounting and Placement.
On the right side of the front panel, turn on the power switch; the display will light. Press the SETUP button. The two-line display will show [SELECT FUNCTION] in the top position, and turning the ROTARY ENCODER will scroll through a list of editable functions. Scroll to [SET CHANNEL] and press the ROTARY ENCODER to select; pressing the SETUP button also will select the function.
CH 1:THH12B |
SET CHANNEL: |
8:00 |
14 |
Note, Turn clockwise to scroll down the list, and counterclockwise to return to the top of the list.
The [SET CHANNEL] edit page will show the currently selected channel. Turn the encoder to change the channel; any channel number other than the one currently selected will flash. Press the ROTARY ENCODER to select the new channel.
Note, The receiver’s RF channel will not actually change to a different frequency until the ROTARY ENCODER is pressed.
To sync the handheld or beltpack transmitter to the receiver, follow the procedure in the following transmitter quick setup sections. For more details on scanning channels and using multiple wireless units together, see Channel Scanning Procedure, Range and Interference Testing, and Minimizing Near / Far Transmitter Effects.
To adjust the output level of the receiver going to the mixing console or other audio equipment, see
Audio Output and Filter Adjustments.
Note, The receiver provides three display modes. The Main Page shows the currently selected channel, transmitter name or designation, remaining battery life, and the performance of antennas A and B. The [SELECT FUNCTION] page has a scrollable list of editable receiver operations. The Edit page allows changes to be made to the currently selected function. The only user operations available are pressing SETUP and EXIT, and turning or pressing the ROTARY ENCODER knob.
