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。

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.

It can be used as a handheld microphone, a lapel microphone with included lanyard, or a belt packmicrophone with optional AL-HSM headset. Each AL-MYNA has a switchlocated under the battery door used to set it’s IR Channel to either A or B. OneAL-MYNA must be set to Channel A and the other AL-MYNA must be set toChannel B. The system will not function properly if there are two AL-MYNAs setto the same IR channel.Also located under the battery door is the LOCKOUT switch. When thisis engaged all function buttons are disabled and the unit can be used as amicrophone only.AL-MYNASpecifications are subject to change without notice.The AL-MYNA can be used in two different modes that effect the control it has over the AL2430 amplifier/receiver. Mode 1: • The right side blue LED will be illuminated• Volume UP / DOWN buttons will control the microphone volume• The Mute button mutes the microphoneMode 2: • Both blue LEDs will be illuminated• Volume UP/DOWN buttons will control the multimedia inputs on theAL2430 Receiver/Amplifier• Mute button will mute the multimedia inputs on the AL2430Receiver/AmplifierPower and Panic buttons function as described below regardless of microphones mode setting.The Power button needs to be pressed for three seconds to turn the unit On or Off.When the Panic button is pressed along with the Mode button, a signal is sent to the AL2430 Receiver/Amplifier. This closes its Panic Output relay. The Panic Output relay can be connected to an external system. For example: the school’s Paging / Intercom system to alert someone of an event in the class room that requires immediate attention.AL-MYNA Microphone SpecificationsIR Led’s 6Aux Input 1, 3.5mm Phono Jack, Mic LevelExternal Controls Power, Panic, Mic VolumeInternal Controls Lockout, Mic A/B ChannelIndicator LED’s Mode (2 Blue), Lockout (1Red), PWR/BATT(1 Green/ Red)Dimensions 5.25" x 1.75" x 1.15" (133mm x 44mm x 29mm) Weight With Battery 4.23oz (120g)Weight Without Battery 2.1oz (60g)AL-MYNA-NEST Microphone SpecificationsAL-MYNA Ports Two Charging PortsCharge Indicator LED’s 4 (Red-Charging, Green-Charged)PSU Type 120V Input, 9VDC, 1A OutputDimensions 4.17" x 7.44" x 2.75" (106mm x 189mm x 70mm)AL-MYNASpecifications are subject to change without notice.Limited Warranty All products manufactured by Atlas Sound are warranted to the original dealer/installer, industrial or commercial purchaser to be free from defects in material and workmanship and to be in compliance with our published specifications, if any.
