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.

sE V系列 V BEAT V CLAMP 麦克风说明书

V KICK • V BEAT • V CLAMPUser Manual - EN Thank youWe would like to thank you cordially for choosing this sE product! This manual contains some important instructions for setting up and operating your new equipment. Please take a few minutes to read the instructions below carefully. We hope you will enjoy working with it as much as we enjoyed designing and building it for you.Most Sincerely,Your sE TeamBrief DescriptionsV KICKThe V KICK is a dynamic microphone intended for use with kick (bass) drums and other sources such as miking bass guitar speaker cabinets, floor toms or other large drums where capturing low-frequency energy is of the utmost importance. Its specialized capsule provides a sound character tailored specifically for kick drums, which can be further shaped with the use of two switches on the rear side of the microphone.V BEATThe V BEAT is a dynamic microphone intended for use with snare or tom drums, but it can also be used on sources such as miking electric guitar speaker cabinets or brass instruments. Its specialized capsule provides a highly detailed, natural sound character on snares or toms of any size.V CLAMPThe V CLAMP was designed to be the perfect companion for the V BEAT for snare or tom miking purposes. Its sturdy elastic clamp enables setup and tear-down within seconds, and it fits any popular snare or tom drum available.Product DetailsV KICKThe V KICK’s specialized capsule provides a sound character tailoredspecifically for kick drums, which can be further shaped with the use oftwo switches on the rear side of the microphone.The left-hand switch shapes the microphone’s overall voicing, with twoselectable options:“Classic” provides a more traditional kick drum sound with a familiarlow frequency punch and a warmer, more rounded sound. If a morecontemporary, aggressive sound is desired, the “Modern”settingemphasizes the low end and high end (a “scooped” sound).The right-hand switch specifically tailors the microphone’s high-frequency character: “Classic” provides a typical bite in the upper midrange (presence boost) and a more rounded andfamiliar HF sound, while “Modern” provides an open, clear and transient-rich top end for a more contemporary, aggressive drum sound.Each of these switches is recessed slightly into the mic body and requires a small flathead screwdriver or similar implement to switch between settings.The V KICK also has an integrated swivel joint that allows for easypositioning inside or outside a kick drum. Its extremely low profile allowsit to fit easily through the drum head port, and the XLR cable and micstand mount are in parallel to minimize cable clutter. Please rememberto securely tighten the swivel clamp whenever adjusting it, so as toprevent the mic from sagging during a performance or recording.V BEATThe V BEAT’s ultra-compact design lets it occupy a minimal amount of space on your drum, without interrupting lines of sight any more than necessary, and keeping it out of the way of drum sticks and cymbals. With the XLR connector and stand mount on the bottom of the V BEAT and in parallel with one another, the footprint and cable clutter are further minimized.Its swivel mount also allows theangle of the mic to be adjusted withgreat precision, so it can be aimed atalmost any part of the drum head tochange the character of the sound,and to minimize spill from otherdrums or cymbals.Please remember to securely tighten the swivel clamp whenever adjusting it, so as to prevent the mic from sagging during a performance or recording.V CLAMPThe V CLAMP can be fitted to any popular snare or tom drum availableby carefully stretching the elastic clamp over the drum rims to fit. Theheight and rotation of the connected microphone can be changed byloosening the V CLAMP’s knob and adjusting the position of the rod. Thisallows the mic to be positioned perfectly for any desired drum tone, or tominimize spill from nearby drums. The small hole at the bottom of therod can be used for a tie clip to attach a cable, or as a backup solution incase the knob becomes loose for any reason.What’s in the boxYour packaging should contain the follow items. If anything is missing, please contact your sE Electronics dealer and let them know.•Thread adapter•Zipper pouch•Spare black internal windscreen•Knurled nut for LP® Mic ClawTips for practical useThe closer the distance from the microphone to the source, the more bass you’ll get (“proximity effect”). Use this to your advantage when you want it - and be aware of it when yo u don’t.Aim the microphone towards the desired sound source, and angle it away from other drums and cymbals to reduce bleed and maximize off-axis rejection.Ensure that the microphone & cable do not touch the drum head, as this may affect the sound. Safety and maintenanceRisk of damagePlease make sure that the piece of equipment to which your microphone will beconnected fulfils the safety regulations enforced in your country and is fittedwith a ground lead.Cleaning the microphoneAfter every use, clean the microphone with a dry, soft cloth tissue and store it in a solid case or a zipper pouch.Technical SpecificationsV KICKFrequency Response Polar PatternV BEATFrequency Response Polar PatternSupportIn case you are experiencing any problems or have any questions regarding your sE product, please contact your dealer first for the fastest and more direct service.

移动和固定安装应用紧凑的高性能解决方案Electro-Voice ®公司，行业先锋 ---- 领导专业音响设置标准来自Electro-Voice 公司的线数组系统：一种真正的优势“Hydra ” – EV ®的平波发生器经过75年来的努力，EV ®现已发展成为顶尖的专业音频设备制造商之一。

在换能器系统和功率放大器的设计和生产方面拥有超过50年的经验。

加上在数字信号处理领域有将近30年的历史，是该公司实现艺术级音频性能的基础。

EV ®设计团队同世界各地的广大客户之间保持着密切关系，这是系统解决方案的基础。

它的卓越的音频质量、可靠性和使用方便性完美地结合在一起。

在专业音频领域中最大的经销商和广阔的服务网络的支持下，EV ®系统代表着超凡的价值。

线数组扬声器技术在行业中已经出现有好几十年，然而直到最近五年它才成为现场演出的标准，并且在固定安装系统中也非常流行。

如今，众多制造商都提供“线数组” 扬声器：一组垂直排列的扩音器箱。

但是，并非看上去像一组线数组就可以理想地工作。

无数案例证明，Electro-Voice ®的X-Line 和XLC （X-Line Compact ）具有“真正的线数组”功能：提供一个非常好的水平分散及非常均匀的前后覆盖。

借助其X-Line VeryCompact ，EV ®的工程师定义了一组新型超紧凑、高性能的线数组。

EV 的X-Line 包括四个XVLS 音箱和两个XVLT 音箱任何音乐信号中最关键的信息位于中高频段，HF 扬声器的数量去决定在一个音乐系统中的表现。

对于一组垂直的多音源而言，应当适当的保持单元与发射波长之间的距离，这一点非常重要。

对于较低频率这不难做到，但是为了产生“平波”，需要相同振幅和相位、但频率超过3kHz （波长大约11cm ，或4英寸）的声波，此时挑战就增加了好几倍。

EV 线数组的成功之处在于其独特的“Hydra ”设计，它是一个具有卓越性能的关键组件。

These modes can be controlled by 2 HW mode_selector input pins (default setting), or by I2C command control set from the host controller/baseband. When the I2C is chosen to switch these modes, then the DSP receives the mode-switch command from the baseband chip through the I2C interface and writes the result to the 2-bit mode_sel registers to handle mode/power control. If the baseband chip chooses the I2C interface to control the mode selection, then some of the CM7001 function blocks will be kept alive while in suspend and power-down modes.7.2Mode state diagram and power managementThe following diagrams illustrate mode switch states and corresponding power levels (level 0-4) for Mode_Sel and the I2C interface respectively.Mode State Diagram Controlled by Two Mode_Sel (1,0) PinsPower Down Mode－●Digital power level 0:No power●Analog power level 0:Minimum analog powerconsumption ENC On Mode－●Digital power level 4:Normal operation●Analog power level 4:Normal operationBypass Mode－●Digital power level 3:By-pass DSP coreprocessing●Analog power level 4:Normal operationSuspend Mode－●Digital power level 1:Digital core onlyconsume static power●Analog power level 1:Analog keeps digital coreLDO voltage onFigure 7.1 Mode State Diagram (by Mode_Sel pins)Mode State Diagram Controlled by I2C Bus● Digital power level 2: DSP core is operated at a lowest frequency ● Analog power level 2: Analog keeps digital core/PLL LDO voltages on● Digital power level 4: Normal operation ● Analog power level 4: Normal operation ● Digital power level 3: By-pass DSP Core processing ● Analog power level 4: Normal operation－● Digital power level 2: DSP core is operated at a lowest frequency ● Analog power level 2:Analog keeps digital core/PLL LDO voltages onFigure 7.2 Mode State Diagram (by I2C interface)7.3 Recommended control methodsThere are three recommended control scenarios for different customer considerations:Mode_Sel pin control for non-custom tuning or programming parameters with the best power savingsIn typical cases, if you need to change some ROM code parameters or set HW registers via the I2C interface, we recommend using Mode_Sel 0/1 pins to easily control the chip operation mode for improved power savings. In this way, the power-down mode will be changed to power level 0, consuming almost no power when on standby/sleep/deep-sleep or power-off modes. During a call, when the phone is active, it will switch to ENC mode via baseband’s active signal pin or a GPIO pin (drive high) to Mode_Sel0 pin. When pulled down, this pin will power-down the phone when a call is ended, returning it to standby status. Another GPIO pin can drive Mode_Sel1 pin high (while Mode_Sel 0 is high at the same time) to enter bypass mode when the user chooses to turn off the ENC function, or if the phone design does not allow it to use the CM7001’s AEC or NR functions in speakerphone and recorder applications. The phone status should match the following operation modes:In this scenario, please note that the baseband needs to program the parameters or HW registers through the I2C every time before entering into phone active/calling status with the ENC chip working (very-short time of ~0.12ms).Mode_Sel pin control for demand to download firmware codes with power savingWhen the default DSP algorithm ROM codes CANNOT satisfy your needs, the CM7001 ENC chip allows the baseband to download a whole new version of codes into the program’s RAM through the I2C interface. In this situation, we still recommend using Mode_Sel 0/1 pins to easily control the chip’s operation mode for better power saving. However , to avoid downloading times (1.16 sec for 32Kbytes FW @ I2C fast mode) every time the phone comes out of power-down mode, it might be necessary to use the suspend mode (Mode_Sel0=low, Mode_Sel1=high) for phone standby or sleep status settings, which will keep the RAM program/data operational.When the phone is active during a call, switch to active ENC-On mode via the baseband’s phone active signal pin or a GPIO pin (Mode_Sel0 pin must be pulled high and the Mode_Sel1 pin must be pulled low at the same time. The reverseposition puts the phone back in standby/sleep mode). Just like scenario one, drive both Mode_Sel 0/1 pins to high at the same time to enter by-pass mode when the user wants to turn off ENC for calls. Again, the phone status should match the following operation modes:I2C-only Control ScenarioThe CM7001 chip also allows the baseband to switch operation modes via I2C programming hardware registers if customers do not want to use additional GPIO control. This means that only the I2C controls the ENC chip,necessitating higher power levels to keep the I2C slave interface and digital core alive the device is on standby. In thissituation, we recommend using the power-down (00) or suspend (10) mode for the phone standby status (in this scenario, these modes are actually the same), which will keep the RAM program/data and I2C operation. Therefore, the baseband does not need to program or download codes every time the phone becomes active for calls.Set registers [1:0] as 01 are used for ENC-On operation while the unit is in operation. It goes back into power down/suspend mode when the call is ended and returns to standby/sleep status. Just like scenarios one and two, setregisters [1:0] as 11 are used to enter bypass mode when the user would like to turn off ENC for calls or otherapplications. The phone status should match the following operation modes via I2C interface writing from the baseband:8.1Absolute maximum ratingsNote：In default analog codec mode, AVDD needs to be >=2.2V to make internal codec work properly.8.2Recommended operating conditionsNotes：1.In default analog codec mode, AVDD is recommended to be >=2.4V to allow the internal codec to work properlyand achieve the best audio quality.2.26MHz is a default assumption for clock source, but other common clock sources on mobile phones, like 13MHzand 19.2MHz, are also compatilbe with proper PLL frequency divider setting.Notes：1.Vih for Mode_Selector pin is recommended to be > 0.75*DVDD for corner case.2.Vil for Mode_Selector pin is recommended to be < 0.23*DVDD for corner case.3.Power supply test conditions: AV DD = 2.8V, DVDD = 1.8V, clock= 26MHz, TA=+25o C, digital mic-in, digital mic-out,Mode_Select pin control mode.

The frequency response is tailored for wide-range sound reproduction with very natural sound pickup for either distant or close-up use. The PC Desktop can be used on lecterns, podiums, desks, table-tops, or other applications. To maximize gain-before-feedback, the PolarChoice’s three directional polar patterns allow the user to pick the directional polar pattern for optimum effect. For those applications where gain-before feedback is not a problem, anomnidirectional pattern is included. Applications requiring speaking close to the microphone at podiums, lecterns, or pulpits normally require a windscreen (included) to control breath noise and P-popping or, in some cases, wind noise from circulating air.Microphone Setup:Refer to Figure 1 for the following switch function descriptions-Switch “A”:Select High-Pass switch position. Start with this switch set to the left (flat response). If the mic is in a location where low frequency rumble or wind noise is a encountered, moving this switch to the right will help by reducing low frequency sensitivity. Flat ( ): Normal response.High Pass ( ): minimum 5 dB reduction in sensitivity at 100 Hz.Switch “B”:Select preferred polar pattern. The cardioid polar pattern works well for most installations. If feedback from a sound system occurs, switching to the supercardioid or hypercardioid pattern will usually allow increased mic gain before feedback. The omnidirectionalpattern is best suited for situations where there is no sound reinforcement system present, such as for recording.Switch “C” and “D”:Controls action of push-button switch on the top of the PC Desktop microphone.Momentary Modes:When switch “C” is set to the left, the push-button (mute) switch action is momentary.In addition, If switch “D” is in the left hand position, the mic willbe in push-to-mute mode.Alternately, If switch “D” is in the right hand position, the mic will be in push-to-talk mode.Toggle Modes:When switch “C” is in the right hand position, the push-button (mute) switch will be in toggle (push-on/push-off) mode.With switch “C” in the right hand position, the setting of switch “D” determines if the mic audio should be muted when power is first applied.If switch “D” is in the left hand position, the mic audio will be on when power is first applied.If switch “D” is in the right hand position, mic audio will be muted when power is first applied.Switch “E” (Logic Mode Select):When switch “E” is set in the left hand position, the PC Desktopoperates as a normal desk microphone. Mic muting and operation of the LED is controlled by the push-button on the top of the mic. With switch “E” in the right hand position, the mic will be in automatic mixer mode, and the following will apply:1.) Mic audio is always on.2.) The automatic mixer controls LED operation and micmuting.Wiring:For non-automatic mixer applications, the PC Desktop comes equipped with a standard XLR style 3-pin male connector. Forautomatic mixer applications, remove the XLR connector and service the cable as needed.Cable Connections:Red – Balanced Audio High Black – Balanced Audio Low Shield – Audio GroundGreen – Logic Ground (Common to shield unless R45 is removed. See Figure 3.)White – Switch Logic Orange – LED ControlLogic Signals:If the PC desktop mic is in momentary mode (see above section on the mute switch), the logic level on the white wire will normally be “high”, and go “low” when the push-button is pressed. If the mute switch is set for toggle mode, the logic will toggle from high to low, or from low to high, each time the button is pressed. (If desired, a pc board change can be done to force the logic to always be momentary, regardless of switch settings.
