Wireless microphones transduce the waveform of audio entering the microphone into an electrical signal and transmit that signal to a tuner over radio waves. In this event, it is an analog wireless system that processes the audio signal as it is in the waveform. On the other hand, it is a digital wireless system that digitally processes the audio signal.More specifically, in the digital system, after an analog signal (waveform) is transduced into a digital signal (asignal simplified by binary numbers 0 and 1) and transmitted by radio, the digital signal is demodulated into an analog signal and then the audio is output. By digitally processing and simplifying the audioinformation to be transmitted, the system can have a variety of advantages, including strong immunity to noise and maintenance of clear sound.Let’s have a look at the “D/U ratio” of analog-to-digital wireless systems. The D/U ratio refers to the ratio of the desired (D) signal to the undesired (U) signal (unit: dB). The desired signal represents the level of that signal, while the undesired signal represents the level of signal interference, otherwise called noise. The D/U ratio decreases as the undesired signal increases. The D/U ratio can be considered to be a value necessary to maintaining clear sound in a wireless system. If a comparison is made of the necessary D/U ratio between analog and digital wireless systems, it is 40dB for analog systems and 20dB for digital systems. From this, it can be seen that the digital wireless system has an edge over the analog wireless system by 20dB in terms of necessary D/U ratio, indicating that the digital system can maintain clear sound in circumstances where a lot of undesired signals are present.» How the Digital Wireless System Works» Why are digital wireless systems resistant to interference signals?Analog System Digital SystemDigital signal processing of analog audioDemodulation of digital to audible analog signal(analog)“H el l o ”Audio (analog)12Wireless receiverBroadcast122Not only can the digital wireless system reduce the influence of noise, it can also maintain clear sound quality by means of digital processing. In addition to this, there are various advantages unique to the digital wireless system.» Use of Multiple Channels in the Same AreaSince the wireless microphone makes itself a source of noise, when using multiple channels in the same area, channels must be arranged to avoid radio interference due to intermodulation interference. In the case of the analog wireless system, the most efficient channel arrangement is as shown in the [Analog] figure below if the intermodulation interference of radio waves is taken into consideration. In this arrangement, the simultaneous use of 6 channels is all it can handle per 4 MHz band.* This is an example.In the digital wireless system, however, since one of its features is being immune to the influence of noise, even when the intermodulation interference occurs, individual channels are less likely to be affected by it. As a result, equal-interval channel arrangements such as shown in the [Digital] figure below becomes possible, allowing up to 10 channels to be used simultaneously per 4 MHz band.* This is an example.» Interference Noise MutingAnalog systems are prone to generation of strange noises when exposed to radio interference. Conversely, radio interference is muted in digital systems, so strange noises are not produced.» Reuse of the Same ChannelAnother advantage of the digital wireless system is that simultaneous use of multiple microphones on the same frequency in the same area can be realized more easily because of its immunity to radio interference and noise.In the case of analog systems, the distance between microphones should be at least 100 meters when using the same frequency channel in the same area to ensure 40 dB of D/U ratio. However, in the case of digital systems, the distance can be reduced to 30 - 40 m*, making it easier to cope with even a building (area) with multiple rooms that require multiple microphones.*This can change depending on antenna mounting conditions or room conditions, such as the thickness or material of walls.Area and RoomRoomRoom» Improved SecurityConventional analog wireless systems transmit their audio signals through FM modulation. With this method, it is possible that communications could be intercepted by general broadband receivers (FM radio, etc.), causing much anxiety in terms of security. On the other hand, with digital systems, since the audio is transmitted through digital modulation, only noise can be heard if received by a broadband receiver. This can prevent exposure of information, leading to improvements in the security of information communication.(Horizontal coverage of antennas, Page 7)the supplied antenna.the supplied antenna.(Installation of the YW-4500 Wireless antenna, Page 7)o Step (3)(Antenna distribution, Page 8, 9)1) Select an arbitrary bank from Banks 1 – 4 at the receiver.

This is necessary for ensuring optimal conditions for one antenna to receive signals when the microphone my experience the other antenna's dead spot. In other words, the shape of the room does not matter provided that the above conditions are met. On a diagram of the site, use a compass to draw two circles representing a radius of 20 – 30m with each antenna as the central point. If usage locations fall within either of the two circles, such locations can be deemed to be okay.Point 2As a guideline, the distance between the two antennas should be 3 – 18m. Although the coverage area becomes wider as the distance between antennas increases, this degrades the diversity effect, and signal interruption will become more liable to occur.If possible, locate one antenna in the direction that can be viewed from the position where the microphone is held, and the other antenna in the opposite direction (behind the microphone holder).Point 3In indoor installations, as a general guideline, install antennas at a height of 2 – 4m above the floor, lest the signal be blocked by people in the room. Keep the antennas about 30cm below the ceiling. Install the antennas so they face in the specified directions. When making protectors, use resin or timber and do not use metallic materials.• Avoid positioning antennas close to metallic objects wherever possible.• Avoid mounting antennas inside a ceiling or wall.• Select locations where the antenna can be protected from being hit and damaged by objects.• Protect the antennas against rain water.Important points for selecting the mounting position of diversity antennas are as follows:Horizontal coverage of antennas under optimal conditionsInstallation of the YW-4500 Wireless Antenna• YW-4500• WT -D5800 Rod Antenna• Using 1 - 3 channelsAntennas can be distributed without using the WD-5800 Antenna Distributor.• Simultaneous use of 4 channels• Simultaneous use of 5 – 8 channelsaudio• Simultaneous use of 9 -16 channels• Simultaneous use of 17 - 32 channelsaudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixerSplit antennas into two systems and construct a system of up to 32 channels.• Frequency table which can be used with 5000 Series analog wireless systemCompatible Frequency List*WM-D5200/D5300, WT-D5800: BANK 1 - 4WM-4200/4300/5220/5270/5320/5225/5265/5325: BANK 1– 4WT-4800/5800/5805: BANK 1– 4WM-4210/4220/4310, WT-4810/5100/5810, WTU-4800: BANK 1• When needing more channels*Banks A - F cannot be used when including existing analog wireless equipment in the system.Compatible Frequency List*WM-D5200/D5300, WT-D5800• Frequency table which can be used with 5000 Series analog wireless systemCompatible Frequency List*WM-D5200/D5300, WT-D5800: BANK 1 - 4WM-4200/4300/5220/5270/5320/5225/5265/5325: BANK 1– 4WT-4800/5800/5805: BANK 1– 4WM-4210/4220/4310, WT-4810/5100/5810, WTU-4800: BANK 1• When needing more channels*Banks A - F cannot be used when including existing analog wireless equipment in the system.*WM-D5200/D5300, WT-D5800• Frequency table which can be used with 5000 Series analog wireless system*WM-D5200/D5300, WT-D5800: BANK 1 - 4WM-4200/4300/5220/5270/5320/5225/5265/5325: BANK 1– 4WT-4800/5800/5805: BANK 1– 4WM-4210/4220/4310, WT-4810/5100/5810, WTU-4800: BANK 1• When needing more channels*Banks A - E cannot be used when including existing analog wireless equipment in the system.*WM-D5200/D5300, WT-D5800• Frequency table which can be used with 5000 Series analog wireless system*WM-D5200/D5300, WT-D5800: BANK 1 - 4WM-4200/4300/5220/5270/5320/5225/5265/5325: BANK 1– 4WT-4800/5800/5805: BANK 1– 4WM-4210/4220/4310, WT-4810/5100/5810, WTU-4800: BANK 1• When needing more channels*Banks A - E cannot be used when including existing analog wireless equipment in the system.*WM-D5200/D5300, WT-D5800When using transmitters in numbers greater than the number of simultaneously usable channels and in close proximity to each other, microphones operating on the same frequency can be used simultaneously by utilizing their digital characteristics. Note, however, that the same frequency cannot be used in the same room.1. Make channel plans1) Referring to the Frequency T able, select an arbitrary bank from A to F . 2) Scan receiver channels.• C band: Searches for channels in two banks including the currently-set bank and displays idle channels.Combinations of scanned banks are as follows: When Bank A or B is currently set a Searches for and displays idle channels in Banks A and B. When Bank C or D is currently set a Searches for and displays idle channels in Banks C and D.When Bank E or F is currently set a Searches for and displays idle channels in Banks E and F .• G band: Searches for all bank channels in the dedicated digital plan, and displays idle channels.3) Assign idle channels to multiple rooms as shown in the following examples to prevent channelsoperating on the same frequency from being too close to each other.[Example] Same floor or same location on each floor.[Example] Multiple rooms are adjacent to each other on both upper and lower floors in facilities like rental conference rooms and schools. There is a high possibility that the frequencies being used in the ‐ Keep channels using the same frequency as far away from each other as possible. If used on the same floor, keep them at least two rooms apart.‐ Set the wireless microphone’s transmission output to “L.”‐ Adjust the antenna attenuator.2. Use "Code" (recommended)This function prevents interference between channels sharing the same frequency. By performing Code settings, receivers and transmitters can be paired, muting radio signals on the same frequency that may exist in the surrounding area. Code setting is effective when the encryption function is not set.» Code setting proceduresFigure a. Even if the code is the same, if the power for both microphones is ON, radio interference will not occur. (Since the stronger radio signal takes precedence, only the microphone within the immediate area is reproduced.)Figure b. If power to either area is turned off when Figure a conditions exist, Receiver 1 may mistakenly receive MIC 2 audio. (Since the code is the same, it would be impossible to distinguish between MIC 1 and MIC 2.)Figure c. If different codes are set in Area 1 and Area 2, mistakenreception will not occur even if power to the microphone for either area is turned off.

The most effective results may not be obtained when interference signals are strong (i.e. when audio interference constantly occurs).•Proper use of two attenuatorsUse either the WT -D5800 or YW-4500 attenuator to attenuate the reception sensitivity by 10dB. The WT -D5800 may be more convenient as it allows settings by hand.Since the attenuation of both the YW-4500 and WT-D5800 attenuators are added together, when wishing to attenuate reception sensitivity by at least 10dB, use both attenuators in combination.(This is a rare case, though.)UndesiredUndesiredFBS SettingIt is a function that the built-in feedback suppressor filter automatically works to suppress acoustic feedback when the feedback occurs.Use this function when increases in the receiving wireless microphone’s sound volume tend to generate acoustic feedback and reduce speech clarity or make it impossible to achieve the necessary sound volume for broadcast.» What is the feedback suppressor function?» What is the FBS built into the WT -D5800?NOTE: Acoustic feedback, or howling, is generated when sound output from a speaker reenters the microphone.

KTV无线话筒的使用技巧
KTV无线话筒的使用技巧随着无线话筒的普及和广泛使用，怎样才能更好地发挥它们的优越作用，下面是店铺为大家整理的关于：KTV无线话筒的使用技巧。
欢迎阅读!KTV无线话筒的使用技巧在操作使用中应注意以下问题：一、怎样选购无线话筒发射机机的电池为保证系统正常使用时不至出现信号失真和频率干扰，必须使用能是充足的电池，在选购时有条件的话最好选用碱性9V电池。
二、怎样才能尽早知道发射机电池能量是否充足在各种品牌和型号的无线话筒系统中，绝大多数接收机不具备发射机电池能量显示功能。
尽管有的无线发射器上有电池低压显示，但使用者在使用中一般很少会注意这个问题。
在无线话筒正常使用中，出现电池不足引起音频信号失真或频率干扰是时有发生的事。
为了防止发生这种现象，操作人员可在无线话筒正常使用中，适时地使用调音台PFL预听功能，用耳机监听无线话筒的信号，若声音清晰度稍有降低或噪声稍有增大时，就应马上更换电池，这样才能尽可能避免由于电池能量不足给操作者带来的心理压力。
三、怎样在演出中途更换电池在演出中更换电池时应方便、快速、简单。
最好的办法是打开调音台通道的“哑音”开关，使无线话筒处于哑音状态，如没有此功能的调音台可先将无线话筒接收器的输出音量关死，然后关掉发射机电源，更换电池后打开发射机的电源，然后将接收器输出音量复原到原来的增益，如接收器没有输出音量开关的话，可关闭调音台输入增益或使用Line/MIC选择器进行切换，待更换电池后开机再将调音台输入增益或选择器复位。
为什么不是将无线话筒通道的推子关死后再更换电池呢?这里需要说明一点，如果利用关闭通道推子的方法更换电池则较为烦琐，在演唱中一般话筒都加有效果处理声，如果一个话筒使用时，另一个无线话筒需更换电池，这时如果关闭该通道推子，则同时还应相应关闭用于混响、延时的辅助通道电位器，如果忘记关闭辅助通道电位器，更换电池时形状无线话筒发射机的电源冲击声就会从辅助通道经效果器输出至混频，直接影响音响效果;再者，如果更换电池后漏开辅助电位器也会出现没有效果声而影响音响效果。
