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.

QTX Sound VHF-series 无线麦克风系统用户手册说明书

VHF Wireless Microphone System (VH1, VH2, VN1, VN2, VHN2, VL1)User ManualFeatures:∙Sleek, ergonomic design∙Auto-mute on signal drop∙Wide frequency responseIntroduction:Thank you for choosing the QTX Sound VHF-series wireless system. This professional wireless set provides a high quality microphone with VHF radio system for freedom of movement without loss of audio quality. Please read this manual before using this equipment in order to avoid damage through incorrect operation and to get the best performance from your purchase. Contents:Please take care when unpacking this product. Inspect for any damage and ensure you have the following components…∙ VHF wireless receiver ∙ Mains power adapter ∙ 6.3mm mono jack lead ∙ 9V battery, PP3 (2 pieces for VH2, VN2 or VHN2) ∙ Microphone / transmitter(s) – see table belowWarning:To prevent the risk of fire or electric shock, do not expose any of the components to rain or moisture.If liquids are spilled on any component, stop using immediately, allow unit to dry out and have checked by qualified personnel before further use. Avoid impact or heavy vibration to any of the components, dropping the microphone can cause capsule failure. No user serviceable parts inside transmitter or receiver - refer servicing to qualified service personnel.Safety ∙ Ensure that the correct adapter is used with adequate current rating and that the mains voltage is as stated on the adapter. ∙ Avoid ingress of water or particles into the transmitter(s) or receiver ∙ Use alkaline or NiMH batteries in the transmitter(s) and remove if unused for long periods. ∙ Observe the correct polarity when replacing batteriesPlacement ∙ Keep all components out of direct sunlight and away from heat sources. ∙ Do not place heavy objects on top of the receiver or transmitter(s) ∙ If rack-mounting, secure the receiver to a 1U rack tray and do not place heavy equipment above the receiver. ∙ Keep the transmitter(s) and receiver away from damp or dusty environments.Cleaning ∙ Use a soft cloth with a neutral detergent to clean the body of the microphone/transmitter and receiver. ∙ Lightly damp sterile wipes may be used on the microphone grille for hygiene purposes ∙ To avoid damage, do not use solvents to clean the componentsHandheld TransmitterBeltpack TransmitterReceiver Rear PanelReceiver Front PanelOperationFor handheld transmitters, insert the supplied 9V batteries by carefully unscrewing the base to reveal the + and - terminals inside the microphone body, connect the battery (ensure + and - are the correct way round) and carefully screw the base back on.For beltpacks, slide the front half of the beltpack upwards just enough to reveal the battery compartment and position the supplied 9V battery inside (ensure + and - are the correct way round) and then slide the beltpack case together as before.Position the receiver within the best available line of sight to the transmitter(s) and connect the DC jack of the supplied power adapter to the receiver and the plug-top to the mains outlet. Extend both antennae fully upwards and outwards slightly and switch the power on. Turn microphone level(s) down on the receiver.Note: for dual sets (with 2 transmitters), both microphones’ outputs will be mixed and fed to both balanced and unbalanced ou tputs.Connect the jack or XLR (optional) lead to the recei ver’s audio output connector, turn down the volume of any equipment (mixer, amplifier etc.) that the signal will be fed into and then connect the jack or XLR to the equipment.Warning! - take care not to point microphones towards speakers – this can cause damaging feedback (loud whistle or howling noise) – try to point microphones away from the speaker cabinets.Move the switch on the handheld or beltpack transmitter to the first notch (MUTE) – the LED should light momentarily (continuous dim LEDindicates low battery). Move on another notch (ON) and gradually increase the microphone level(s) on the receiver, then increase the volume on the mixer or amplifier until the sound from the microphone can be heard through the equipment.During use, it may be useful for the reception of the microphone to be muted for a short period of time (e.g. to avoid feedback when walking across the front of a speaker or avoid handling noise when placing the microphone down momentarily or adjusting a neckband microphone). In these circumstances, it may be better to move the transmitter switch to the “MUTE” position, which maintains the radio freque ncy carrier signal but mutes the microphone input. When this switch is moved back to the “ON” position, the sound will be immedia tely restored without waiting for the radio signal to be reinstated.If the wireless system is not to be used for more than a few seconds, it is preferable to slide the transmitter switch to the “OFF” position, which mutes and deactivates the radio signal and powers down the transmitter. Be sure to turn down the volume of the mixer or amplifier and then switch off the receiver. Unplug signal leads from the receiver and mixer or amplifier when moving or packing away.If the system is not to be used for long periods of time, remove the batteries from the transmitter and unplug the power adapter from the receiver and the mains outlet. Retracting the antennae can also help avoid damage when the system is not in use.TroubleshootingNote: for further troubleshooting, refer equipment to qualified service personnel for testing© QTX Sound 2011。

uhf-902使用说明

uhf-902使用说明
1、不要用手握话筒的网头。

因为所有话筒的受话部分均有一定的指向性，如果用手握住网罩部分，会改变话筒的指向性和频率响应，还会由于手掌的聚集效应，产生回输、啸叫等影响。

2、不要手握话筒的天线发射部位。

一般手持式话筒，其发射电路及天线位于话筒的下部（远离咪头那一端），当人手接触到天线部位时，大多数射频能量因无法进入空气中而丢失，降低无线系统的使用范围，影响接收效果。

3、应适当保持话筒与嘴的距离。

在使用手持无线话筒时，话筒与嘴巴的距离一般保持在5-10厘米为佳，过近会产生近讲效应，过远声音很轻，均会破坏音质；在使用领夹式话筒时，要防止话筒离嘴巴过远，尽量靠近嘴部；使用头带式话筒则是要避免嘴巴正对话筒头，避免发声气流的冲击，应往两边移一下。

4、避免将话筒直接指向音箱。

如将话筒直接指向音箱，就整个系统来说，形成了一个闭合环路，会产生正反馈（啸叫），这是必须避免的。

5、尽量避免将两个无线话筒发射器靠在一起，以免产生互调干扰。

相信随着人们生活水平的发展，无线话筒一定会普及到我们每一个家庭中，但大家在使用无线话筒的时候一定要注意以上所述的一系列的注意事项。

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 无线话筒经是多年来成功经验设计及生产。

ATW-3000a系列无线系统工作于25MHz频段范围内，提供200组通信通道设定：G频段为721.500-746.375MHz(电视频道55-60)。

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(32mV)及非平衡方式(50mV)。

使用有屏蔽的音频线连接到混音器：如果混音器输入端子为XLR卡农平衡输入，则从接收机背板的XLR卡农平衡输出端子，以屏蔽音频线连接到混音器；反之，如果混音器的输入端子是6.3mm的插座，则从接收机背板的非平衡输出端子以屏蔽音频线连接到混音器。

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。
