These numbers are located on the rear panel of the unit. Space is also provided for other relevant informationModel NumberSerial NumberDate of PurchasePlace of PurchaseSelecting fine audio equipment such as the unit you’ve just purchased is only the start of your musical enjoyment. Now it’s time to consider how you can maximize the fun and excitement your equipment offers. VocoPro and the Electronic Industries Association’s Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion and, most importantly, without affecting your sensitive hearing.Sound can be deceiving. Over time your hearing “comfort level” adapts to a higher volume of sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.To establish a safe level:• Start your volume control at a low setting.• Slowly increase the sound until you can hear it comfortably and clearly, and withoutdistortion.Once you have established a comfortable sound level:• Set the dial and leave it there.• Pay attention to the different levels in various recordings.Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for a lifetime.Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Association’s Consumer Electronics Group recommend you avoid prolonged exposure to excessive noise. This list of sound levels is included for your protection.���������������������������Level������������ExampleQuiet library, Soft whispersLiving room, Refrigerator, Bedroom away from traffic Light traffic, Normal ConversationAir Conditioner at 20 ft., Sewing machineVacuum cleaner, Hair dryer, Noisy RestaurantAverage city traffic, Garbage disposals, Alarm clock at 2 ft.��������������������������������������������������������������Level��������������ExampleSubway, Motorcycle, Truck traffic, Lawn MowerGarbage truck, Chainsaw, Pneumatics drillRock band concert in front of speakersGunshot blast, Jet planeRocket launching pad-Information courtesy of the Deafness Research FoundationListening For A LifetimeSpecifi cationsReceiverCarrier Frequency Range: UHF 614~694MHzOscillation Mode: Quartz Controlled Fixed Frequency Stability: 10 PPMSensitivity: 1.6uV @ sinad =12dBMax.

The most common applications and placement techniques are listed below. Keep in mind that microphone technique is largely a matter of personal taste, and there is no one “correct” microphone position.Proximity EffectWhen the sound source is less than ¼ in. from the microphone, the microphone boosts bass frequencies (by 6 to 10 dB at 100 Hz), creating a warmer and richer bass sound than when farther away. This effect, known as proximity effect, happens only in unidirectional dynamic microphones like the UHF-5805.FeedbackFeedback occurs when the amplified sound from any loudspeaker reenters the sound system through any open microphone and is repeatedly amplified. Most commonly, feedback is caused by the following condi-tions: placing loudspeakers too close to microphones, having too many open active microphones, boosting tone controls indiscriminately (mainly treble) and performing in areas with high ratios of room surfaces that have hard and reflective surfaces such as glass, marble and wood. What to do if feedback occurs before the sound system is loud enough?• Request that the talker speak louder into the microphone.• Reduce the distance from the talker to the microphone. Each time this distance ishalved, the sound system output will increase by 6dB.• Reduce the number of open microphones.• Move the loudspeaker farther away from the microphone. Each time this distance isdoubled, the sound system output can be increased by 6dB.• Move the loudspeaker closer to the listener.• Use an equalizer/feedback reducer to cut the frequency bands in which the feedbackoccurs.Microphone Placement & Tone QualityLead & Backup VocalsLips should be less than 3” from or even touching the windscreen on an axis to the microphone. Doing this creates a robust sound, emphasizes bass and provides maximum isolation from other sources.SpeechWhen giving a speech or simply speaking, place the microphone 4” to 10” away from the mouth, just above nose height for a natural sound with reduced bass. You can also place the microphone 8” to 16” away from the mouth, slightly off to one side, for a more “distant” sound with highly reduced bass and minimal “s” sounds.Before getting startedBefore starting any installation procedures, it is recommend to completely unpack all the package contents. The original packaging should be kept in the event that re-shipping is needed. Upon unpacking the UHF-5805, you should have received the following items:•Custom Aluminum Travel Case (1)• UHF-5805 Receiver (1)• Handheld Microphones (4)• 3 ft. male/male ¼” cable (1)• 14V DC Main Unit power adapter (1), 9V DC Charger power adapter (2)• Dual Microphone Charger (2)9V9VUniversal Mic Charger Universal Mic Charger14VTo install the UHF-5805 to a 19” rack case, complete the steps below.1. Attach mounting brackets to the UHF-5805 via the supplied mounting screws.2. Align the UHF-5805 with the desired space in rack and slowly slide in, rear panel first.3. While aligned, use rack case screws (not included) in the order shown below to stabilize the UHF-5805 in its space, using the “X” rotation (numbered below) will ensure even tension and flush alignment.MountingNOTE: Depending on your rack case design, it may be neces-sary to allow for sufficient space for the antennas.NOTE: Do not tighten screws firmly until all screws are in place.����Maintenance proceduresRemoving the Field Replaceable ModulesEach of the 4 microphone modules on the UHF-5805 were designed in a way that allows them to slide out. This is a convenient feature if ever a module needs to be repaired or replaced.1. Remove the two screws that fasten the module to the front panel.2. To remove the module, simply slide the module out of the compartmentNOTE: It might be helpful to use a flat-head screwdriver to nudge the module out of its compartment.3. To re-insert, slide the module into compartment until it is completely secured. Secure the module withthe screws.The UHF-5805 comes with two dual chargers that let you charge all four microphones at the same time.Charging the MicrophonesIf the LED light on the microphone(s) does not light up when the microphone is turned on, this indicates that the microphone needs to be chargedTo charge:1. Place the microphone in the charger slot, the LED on the charger will be lit while the microphone is charging.2. When the LED on the charger turns off, the microphone is charged and can be removed.NOTE: For longest battery life, be sure to turn the microphones off when not in use.Reading the LED IndicatorsThe LEDs on the charger indicate the charging status. There are three states: blinking, on, and off.• Blinking - The power is connected to the charger but there are no microphones being charged • On - The microphone is being charged• Off - The microphone is completely charged and can be removed.Charger and Microphone Descriptions and Functions1.

(With the speakers located in these positions, the possibility of feedback is greatly reduced).• Always check the stage setup before a performance to ensure optimum placement of microphone and monitors.IMPORTANT: Every wireless microphone installation is a unique situation, and can present a variety of prob-lems. Never attempt a live performance without first conducting a “walkthrough” test of the system in the performing area. If major changes (additional wireless systems or intercoms, relocation of scenery, etc.) have been made since the last walk-through test, check the wireless system again, as close to performance time as possible.P.A. Speakers Facing AwayFrom Rear of MicrophoneMonitor Directly BehindMicrophoneOperations2. Adjust the receiver’s VOLUME controls to approximately 50%.3. Switch the microphone’s POWER BUTTONS to the ON positions.4. Talk or sing into the microphones. During normal operation, the RF/AF signal LED’s will light when amicrophone is being used.5. Adjust the receiver’s VOLUME controls until the output levels are balanced w ith each other and otherpossible source output i.e. CD+G tracks.TroubleshootingProblemsNo sound output, RF/AF LED(s) are not glowingReceived signal is noisy or contains extraneous sounds with the microphone(s) ON.There is noise coming from the receiver with the microphones turned OFF.Momentary loss of sound as microphone(s) are moved throughout the operating range.Solutions• Make sure the microphone and receiver power switches and receiver are set to the ON position.• Check microphone charge to ensure there is sufficient power. Charge mic if necessary• Check receiver’s AC power connection.• Make sure antennas are firmly connected and extended to an optimal position.• If necessary, reduce the distance between the microphones and receiver.• Turn up the receiver’s VOLUME level controls.• Check for proper connection between receiver and external amplifier/mixer.• Talk into the microphone and observe the receiver’s RF/AF signal LED’s. If they glow, the problem is elsewhere in the sound system.• Check microphone(s) charge and recharge if the charge is low.• Remove local sources of UHF interference, such as lighting equipment.• Adjust the squelch controls on the front of the UHF-5805 receiver.• Signal may be too weak. If so, reposition antennas. (If possible, move them closer to the transmitter).• Remove local sources of UHF interference, such as lighting equipment.• Reposition the receiver or antennas.• Reposition the receiver, perform a “walkthrough”, and observe the signal strengths. If audio dropouts persist, mark these “dead spots” in the operating area and avoid them during the performance.UHF-5805 Manual © VocoPro 2011V 1.1Erratic LED blinking on the main receiver modules• Make sure the 14V power adapter is pluggedin to the main unit.

无线话筒调频知识
无线话筒调频知识第1步、认识无线话筒1、无线话筒的分类。
无线话筒也称之为无线麦克风，按其频率是否可调节，分为固定频率无线话筒和可调频率无线话筒。
区分无线话筒是固定频率无线话筒，还是可调频率无线话筒，最直观的的方法是看话筒外观是否有液晶显示屏。
一般情况下，固定频率无线话筒是没有液晶显示屏的，而可调频率无线话筒的话筒身上都有液晶显示屏，固定频率的无线话筒和可调频率的无线话筒的外观如下图所示步骤阅读步骤阅读2无线话筒按其使用的制式的类型分为三种，分别是FM无线话筒、VHF 无线话筒和UHF无线话筒。
a、FM 无线话筒：俗称FM是指FM 88-108MHz国际调频广播频段。
早期消费性无线话筒是利用FM收音机来接收，系统简单，成本低廉，但因使用效果，不能满足专业品质的要求，21世纪只能成为小孩或学生的玩具。
b、VHF无线话筒：又分为低频及高频段两类型，前者使用VHF50MHz的频段，因频率较低，使用天线长度太长，又最容易受到各种电器杂波的干扰，因此这一类型的产品，在21世纪已经被高频段所取代而逐渐从市场上消失。
后者使用VHF200MHz的频段，因频率较高，使用天线较短，甚至可以设计成隐藏式天线，方便，安全又美观，受电器的杂波干扰又大为减少，电路设计极为成熟，零件普及价格低廉，所以成为当今市场上的热门机种。
c、UHF无线话筒：使用频率为300-3000M的无线话筒。
是21世纪话筒应用的主流。
因为避免了V段的对讲机等的干扰，所以稳定性有很大提高。
步骤阅读32、查看无线话筒的频率。
固定频率无线话筒是没有液晶显示屏的，其频率值一般标帖在话筒电池仓内，且频率不可调节，扭开电池仓后盖，即可见本只话筒的频率，如下图所示本只话筒的频率为：步骤阅读4可调频率无线话筒的话筒身上都有液晶显示屏，通过这个液晶显示屏，我们就可知道这只无线话筒使用的频率和信道值，如下图所示本案例当前使用的可调频率的无线话筒的频率为：，信道为：181信道第2步、调频1、设备连接。

但是如果是专业的UHF 麦克风需要具备以下特点：1.具备网头锁紧结构并配用高强度防撞钢性网头，在营业场所以防止客人拆解麦克风而造成损坏;2.采用简单按键开关，麦克风外观上再没有其它按钮或者可调部件，完全避免误操作造成故障;3.网头部位有六角防滚橡胶圈，放在桌面不易滚动;麦克风尾部有保护橡胶套，跌落时不易损坏;4.以自动搜索空闲信道，快速准确地找到无干扰的用信道，大大简化工程安装中的调试工作;5.音码静音设计(数字导频)，具备音码锁定功能或者身份识别功能，彻底杜绝干扰和窜频现象：在麦克风所发射的信号中，包含音码频率;接收机在接收到信号后，会检测信号中的音码频率。
干扰信号不会包含这种特定的音码频率，所以接收机以将不包含音码频率的干扰信号拒之门外，大大提高了接收机的抗干扰能力。
这一功能最大程度地满足了多台产品同时使用的场合，例如舞台演出、KTV包房、学校教室等.6.采用专门设计的音头，针对人声的特点进行了均衡调校，使您讲话或者唱歌都能轻松自如。
7.具备自动静音及冲击消除电路，避免开关机时的冲击和噪声，防止影响现场气氛甚至损坏扩声设备;8.麦克风内部采用双升压电路设计，电池电压下跌时，不会降低发射功率，不会缩短操作距离。
干扰信号拒之门外。
静噪门一般在产品生产时设定，能适合大多数应用场合。
静噪门设定得比较低时，接收机能够接收到更弱的信号，即反映出接收距离比较远，但是抗干扰能力就弱些，比较弱的干扰信号也能通过接收机输出;静噪门设定得比较高时，接收机抗干扰能力就比较强，同时接收距离就会缩短，需要麦克风比较靠近接收机，才能有足够强度的信号供接收机接收和输出。
1设置与开启接收机将接收机的音量推钮置于较小音量位置，并将扩音机的音量旋钮也调到较小位置，然后按下接收机电源开关。

用户选择了我们的产品，并对其感到非常满意，都源于我们的产品在质量、性能及可靠性等各方面的优良表现。
Audio-Technica 的无线话筒是以多年来成功的经验设计及生产。
接收机宽度是标准的19英寸机架宽的一半，两部接收机(工作于不同频率)可以通过使用AT8630安装套件并排装在一起。
请注意在多系统应用时，对于每一个所需要的信号，必须有一个发射机—接收机组合(每部接收机应与一部发射机配合工作)，并设定到一个单独的频率上工作。
由于一些无线频率接近或位于UHF 电视频段内，在特定的地区只有特定的频率可用，并且，只有某些频率可以与其它UHF 仪器靠在一起工作。
安装：1. 为使设备运行达到最佳状态及减少反射，接收机距离地面的高度要高于1米，距离墙壁或金属表面至少1米。
2. 保持天线远离噪声源，例如：数字设备、电视机、汽车和霓虹灯，同时也要远离大面积金属物体。
3. 接收机放置的地方至发射机常用的地点之间，应尽可能减少障碍物。
视线内为最佳。
4. 当两个发射机同时使用的时候，发射机与接收机的间距要至少2米。
连接：1. 接收机背板上设有两类音频输出端子，分别为平衡方式(12.5mV )及非平衡方式(25mV )。

uhf无线麦克风对频说明
今天来介绍一下怎么对频。
以无线话筒鼻祖的话筒举例。
你可以看看功能设置是不是跟你的一样，照做就行。
放大一点给你看，每一组按键控制一个屏幕。
我用工厂里面还没有装外壳的手持话筒举例哈
第一步：先用话筒的IR对频点对准主机的IR红点。
对准喽，它们的距离是2厘米哈
第二步：按一下SET键
第三步：它们正在自动对频：（注意话筒你可以横着对频，也可以竖着对频，不要乱动就行哈，我分几次拍照搞成横竖的啦）
对频完成后，它是这样的。
以上就是的方法了哈。

专业UHF无线麦克风说明书
专业UHF无线麦克风说明书产品简介：本系列专业无线麦克风设计用于专业舞台演出、体育场馆、高档KTV 包房和大厅、学校课室和多媒体室及高品位的家庭使用，配合专业级的功放、音响、点歌机和大屏幕电视的使用。
具备以下特点：1.具备网头锁紧结构并配用高强度防撞钢性网头，在营业场所以防止客人拆解麦克风而造成损坏；2.采用简单按键开关，麦克风外观上再没有其它按钮或者可调部件，完全避免误操作造成故障；3.网头部位有六角防滚橡胶圈，放在桌面不易滚动；麦克风尾部有保护橡胶套，跌落时不易损坏；4.以自动搜索空闲信道，快速准确地找到无干扰的用信道，大大简化工程安装中的调试工作；5.音码静音设计（数字导频），具备音码锁定功能或者身份识别功能，彻底杜绝干扰和窜频现象：在麦克风所发射的信号中，包含音码频率；接收机在接收到信号后，会检测信号中的音码频率。
干扰信号不会包含这种特定的音码频率，所以接收机以将不包含音码频率的干扰信号拒之门外，大大提高了接收机的抗干扰能力。
这一功能最大程度地满足了多台产品同时使用的场合，例如舞台演出、KTV 包房、学校教室等.6. 采用专门设计的音头，针对人声的特点进行了均衡调校，使您讲话或者唱歌都能轻松自如。
7.具备自动静音及冲击消除电路，避免开关机时的冲击和噪声，防止影响现场气氛甚至损坏扩声设备；8.麦克风内部采用双升压电路设计，电池电压下跌时，不会降低发射功率，不会缩短操作距离。
关于干扰常识无线麦克风是利用无线电波在空间的辐射传播来传递声音的设备，需要发射无线电波和接收无线电波，因此不避免地会遇到无线电波干扰的问题。
设备所处的空间里，会有许多其它设备发出的无线电波信号，例如电视发射台、雷达站、无线电台、无线对讲机等，会发射出自身工作所需的无线电波，这些电波信号一般情况下分布在频谱图的不同位置，即具有不同的频率，而接收设备(接收机)具有选频接收的能力，所以一般情况下不会受到干扰。
是当其它信号的频率足够接近接收机的接收频率时，就能产生干扰，即接收机接收到其它信号而发出不需要的声音，尤其是其它信号又比较强的时候，更容易出现这种干扰现象。

This shows how much battery power is left in your mic/bodypack transmitter. Always check this battery level if you are having trouble connecting your mic/bodypack transmitter. When the lock indicator is lit, the controls are‘frozen’ to avoid accidental changes. To unlock, simply press and hold the Set button (2.). For further instructions onthe display please read below.Receiver operation1. Connect audio outputs for channel A and B to your mixer/amplifier/PA speaker system, choose either two balanced XLR cables for dual output or a single unbalanced 6.35mm jack cable for mixed output of both channels.2. Turn down the volume controls on your mixer/amplifier/PA speaker system before connecting your transmitters.3. Connect the DC power supply to the receiver (10.) and plug into an appropriate power outlet.Automatic transmitter connection to receiver (ACT)1. Ensure that the microphone/bodypack is turned OFF and the receiver is turned ON.2. Decide which of the 16 frequencies you wish channel A to operate on. In this example we will choose the first frequency (863.00MHz). On the receiver unit, press and hold the Set button (3.) until the word ‘Channel’ starts flashing on the receiver display (4.). Press the up or down buttons (2.) to move through the frequencies until you reach your chosen frequency (e.g. 001 / 863.00). Press and hold the Set button (2.) for three seconds to select the frequency and move on to connecting the mic/bodypack transmitter. The ACT icon will now flash on the display.3. Remove the battery compartment cover on the handheld mic or open the bodypack battery compartment.4. Now turn ON your mic/bodypack transmitter.5. Ensure that there is a short and direct line-of-sight between the transmitter infrared connect window (13. on the mic or 22. on the bodypack) and the receiver’s infrared connect window (5.). In other words, point the front of the mic or the open battery compartment of the bodypack towards the right hand side of the receiver’s front panel.6. When the mic/bodypack display (12./21.) shows the same frequency as the receiver, the two are connected. The RF indicator should also change to indicate the connection and the ACT icon will stop flashing.7. If the receiver displays stops flashing before connection, press the Set button again to restart the process.8. To test the connection, speak into the mic, the AF indicator should change indicate that the unit is receiving an audio signal. To test the bodypack, attach one of the mics or an instrument to the bodypack input socket (16.), turn up the volume control (17.) and speak/play, the AF indicator will change to indicate that the unit is receiving a signal.Whenever the mic/bodypack transmitter or system are turned off and then turned on again, the ACT connection should remain in place until you change the channel frequency on the receiver. This allows the mic/bodypack to be turned on and off during performance. If for any reason the connection is lost, simply repeat from step 1.To connect the second microphone/bodypack to Channel B, repeat the above procedure from step 1. (but choose a different frequency in step 2.). To avoid interference between the two channels, ensure that your chosen frequencies are not too close to each other (e.g. 1+2), instead choose two separated frequencies e.g. 1+14 or 5+15. When both channels have transmitters connected, turn up the channel volume controls on your connectedmixer/amplifier/PA speaker system, you should hear the signal coming through and you can adjust the volumes to suit your performance. To adjust the output volume of each channel of the receiver, press the up/down Selection buttons (2.) to increase or decrease the volume.VERY IMPORTANT - if you wish to run 2 receivers and 4 transmitters together and to avoid interference between the two systems, it is recommended you use the following setup:Unit 1 - set channel A to frequency 1 and set channel B to frequency 14.Unit 2 - set channel A to frequency 5 and set channel B to frequency 15.Other functionsTo search for a free channel on the receiver, press and hold the Set button (3.), press the Set button repeatedly until Frequency on the display begins to flash. Use the up/down Selection buttons (2.) to find a free channel, then press the Set (3.) button again to confirm your choice.To adjust the mic/bodypack transmitter power output, press and hold the Set button (3.), press the Set button repeatedly until POW on the display begins to flash. Use the up/down Selection buttons (2.) to choose either HI (high power) or LO (low power), then press the Set (3.) button again to confirm your choice.TroubleshootingIf you are having trouble connecting the mic/bodypack transmitters to the receiver, first check whether you have fresh working batteries correctly installed. Weak or dead batteries will NOT be able to make a connection. If you still fail to connect the two, start by turning both units OFF for 5 seconds, then turning the receiver only back on and starting the connection procedure from step 1. If you get intermittent interference while using a handheld microphone ensure that you are holding it in them middle and NOT by either end as this is where the antennas are situated.。

今天来介绍一下对频。
以无线话筒鼻祖的话筒举例。
你可以看看功能设置是不是跟你的一样，照做就行。
放大一点给你看，每一组按键控制一个屏幕。
我用工厂里面还没有装外壳的手持话筒举例哈。
第一步：先用话筒的IR对频点对准主机的IR红点。
对准喽，它们的距离是2厘米哈。
第二步：按一下SET键。
第三步：它们正在自动对频：（注意话筒你可以横着对频，也可以竖着对频，不要乱动就行哈，我分几次拍照搞成横竖的啦）
对频完成后，它是这样的。
以上就是的方法了哈。
