通常情况下，头戴无线麦克风都配有一个接收器，用户只需将接收器插入输出设备（如扬声器、耳机等）的音频接口中即可连接。
如果无法匹配，可以尝试重新对麦克风和接收器进行匹配。
3. 调节音量如果接收器与麦克风成功连接，则可以进行音量调节。
不同的设备，音量控制的方法会有所不同，但通常情况下，可以通过音频设备本身的音量控制功能进行调节。
如果需要调整麦克风的音量，则需要根据麦克风所配备的控制面板进行调节。
4. 开始使用最后，用户可以开启头戴式无线麦克风进行使用。
如果需要录音，则需要将麦克风调整到适当的位置，并保持安静的环境，以避免录入无用信号。
如果需要进行语音聊天，则需要确保麦克风的音量不会太大或太小，以免影响语音通话效果。
三、使用技巧1. 保养无线麦克风头戴无线麦克风由于是直接接触人体皮肤的设备，所以需要注意保养。
尽量避免长时间使用，以免引起不必要的疲劳。
同时，在使用的过程中，需要注意清洁设备，定期更换麦克风的耳套等易耗品，以保证使用效果。
2. 预防干扰信号由于无线麦克风可能会受到其他设备干扰，所以在使用过程中，需要尽量避免接收器靠近其他无线设备，以免产生信号干扰。

d p a m i c r o p h o ne s.c o m/df i n eOmnidirectional characteristics• The mic is sensitive to sound from all directions• The sound remains more or less the same regardless of the distance between the sound source and the mic• The positioning of mic with omni characteristics is less critical than with directional• An omnidirectional microphone is generally not very sensitive to wind, breathing, pop and handling noisesDirectional characteristics• Rejects background noise and creates higher separation• The mic is most sensitive to sound on one side (marked on some variants)• The positioning of mics with directional characteristics is essential as the low frequency level will change according to the distance to the mouth, known as proximity effect• Choose a distance that yields the desired amount of bass• Care should be taken to protect against wind and pop noise e.g. by using a windsceenIntroductionAll d:fine TM Headset Microphones provide a uniquely natural and opensound. Ultra-lightweight and adjustable, these mics ensure a secure andcomfortable fit in live performance environments. To ensure optimal performance of your d:fine Headset Microphone, please follow the simple instructions below. Placement of microphoneFor discreet placement, you can bend the microphone boom slightly so that the capsule is placed in the desired position. Do not hold the capsule while bending; bend the wireboom, making a smooth curve with your thumb to best fit the profile of the face.Mount a directional mic 2-3 cm (1 in) from the corner of the mouth to ensure optimal sound quality compared to an omnidi-rectional mic that can be placedfurther away from the mouth.How to tell the difference between d:fine TMHeadset Microphone capsulesSee the mark on the capsuleSee the mark on the capsuled:fine TM CORE 4166d:fine TM CORE 4188d:fine TM CORE 4066, CORE 4266d:fine TM CORE 4088, CORE 4288The size of the headset mount can easily be adjusted. Change the standard bend by carefully expand-ing the distance between the earhooks.To change sides, simply click the boom out of the clips and switch it over to the other side. The remaining two clips are not used. The soft cable must not be attached into the clips.For the single-ear, just open the spring hook lightly, first place the slide behind your ear-lobe (Pic. 1) and let go of the spring over your ear (Pic. 2). For the dual-ear, place the headset behind your ears and place the springs like for the single-ear. Adjust the headset mount by pulling or pushing the wires until it fits tightly (Pic. 3).A directional headset should be mounted 2-3 cm (1 in) from the corner of the mouth to ensureoptimal sound quality.Correct placement behind the earlobePic. 1Pic. 2Pic. 3See instruction video at /dfinePosition the microphone properly by pulling or pushing the boom along the slide.Switch between left and right ear wearing style simply by rotating the microphone boom. Hold on to the earhook while gently turning the boom.For the dual-ear versions, also rotate the two earhooks.Adjust the microphone boom to follow the shape of your face by gently bending the soft steel on the cable hanger.Adjust the angle of the cable run, also by gently bending the soft steel (see arrows). Position the cable as shown on the picture for securing the position of the microphone.The cable relief on the dual-ear version should be fixed in the clip that also holds the two wires on the mount.Always leave the protection grid on the d:fine TM 4166 Omnidirectional & 4166 Directional capsules, as it protects the inner grid and offers protection against wind and breathing noise. The protection grid is replaceable.Service connector to exchange cables or booms on d:fine TM 4166, 4266, 4188 and 4288 Headsets These d:fine TM Flex Headset Microphones offer exchange of cables or microphone booms. Simply locate the service access point, pull back the small locking cap and gently pull the boom away from the cable hanger.WindscreensThe enclosed windscreens offer additional protection against wind and pop noise. Gently draw the windscreen over the microphone head. For even better protection, bigger windscreens are available.Sweat stopThe microphone is equipped with a transparent sweat stop around the microphone boom to prevent sweat running along the microphone boom to the microphone head.Accessories(see more at /accessories)Grids and windscreens, cables, adapters, booms and earhooks.Cleaning d:fine TM 4066 & 4266 mic gridsRemove the mic grid from the mic element and clean the grid using a soft cloth and demineralized water only. Make sure the grid is dry before remounting it on the mic element. This is not possible on the d:fine TM 4088 and 4288 types as the diaphragm is protected inside the mic housing and the protection grids are not removable. Therefore, for these two mics, no attempt should be madeto clean the grid surface and extreme care should be taken not to clog the grids with makeup e.g.Clothing clip for d:fine TM 4266 & 4288 Head-set typesThe supplied clothing clip allows you to at-tach the cable to your clothes, thus relieving the cable draw to the headset mic. This is essential on especially the single-ear headset mic.Color codes & cable steerd:fine TM 4166 Omnidirectional & 4188 Direc-tional Microphone types come with a number of cable steer clips in different colors. Mounted on the cable relief, this clip allows for quick rec-ognition of a specific headset microphone.Protection capThe d:fine TM 4166 Omnidirectional & 4188 Di-rectional Microphones come with a red plastic cap which serves to protect the microphone head when putting on makeup, hairspray and more. Remove the cap before use.Cable maintenanceThe cable is usually longer than required. Make sure that superfluous cable is wound up in soft figure-of-eight loops (preferably 6-8 cm (2.5-3 in) diameter) and avoid kinks in the cable.Use Ecotech2 Multi Degreaser from Finish Line to remove residue from tape, glue, or makeup on the cable. Do not bend the cable or rub it harshly, it may stress the inner cores of the cable and cause them to break over time.General maintenanceThe d:fine TM Headset Microphones are resistant to high levels of humidity. How-ever, care must be taken to keep the mic away from exposure to water and cleaning fluids and to keep the mic head dry at all times. Do not use spray or use fluid containing chemicals that could remove static electricity on or close to the microphone. This could cause permanent damage. MicroDot connectors and adaptersT o provide users with safe and compact mounting of connec-tors, all headsets from DPA are fitted with the MicroDot con-nector as standard. A broad range of connection adapters is offered as optional accessories for most wireless systems for professional use.

领夹,头戴话筒应用基础
领夹，头戴话筒应用基础领夹话筒通常是夹在衣服或演出服装上的，很适用于演讲。
跟领夹话筒一样，头戴话筒的声源是讲话声和歌声。
不需要的声源包括其他人的声音、乐器的声音、环境噪声和音响系统扬声器的声音。
领夹话筒领夹式话筒的声源是讲话的声音（或者是偶尔的歌唱声）。
而不需要的声源包括其他人的说话声、衣服或者移动产生的噪声、周围环境的噪声和扬声器的声音。
通常平衡式低阻抗输出的领夹话筒是客户的首选。
通过动圈和电容话筒头来获得足够的灵敏度，因为这两种话筒的放置位置相对来说很接近声源。
然而，通常电容话筒更能得到人们的青睐。
它的结构设计更适合于佩戴在衣服上使用。
并且它可以通过别针、大头针或者是挂在脖子上的绳索来佩戴在身上。
体积小这一特点更是它的优势。
对于电容话筒来说，一些必需的电子元件通常被放置在一个单独的小盒子里，当然这个盒子也可以佩戴在身上或者是放在口袋里。
而有一些电容话筒直接把电子元件集成在话筒连接器里。
领夹式话筒必需对话筒线进行合适的管理和固定，以便于用户可以移动使用。
领夹话筒的安装位置应该尽量接近嘴，通常放在西服翻领、领带和系索的下面，对于长的礼服或者是其它的礼服来说，要放置在领口的位置。
全指向话筒可以接收任意方向上的声音，而单指向话筒只能接收来自嘴方向的声音。
尽量避免把话筒放置在衣服的底层，或者是避免放在衣服或其它物体能够接触或摩擦到话筒的地方。
对于单指向话筒来说，这一点尤为重要。
定位并固定话筒线，以使话筒被拖拉的距离减到最小，并且还要保证走路的时候不能踩到或是绊到话筒线。
而无线领夹话筒就消除了这种问题，并且能够完全自由的移动。
这里再说一遍，一定要使用优质的电缆线和连接器，有时需要幻象电源供电。
电容领夹话筒即使在非常小，性能也非常好。
在不能提供幻像电源，或者话筒体积大小无所谓的情况下，也可以使用动圈式领夹话筒。
领夹话筒有一个特殊形状的频率响应图，用来补偿离轴位置高频的损失，以及某些情况下胸腔共鸣所带来的中频提升。

浅析话筒的使用技巧
浅析话筒的使用技巧话筒（Microphone）简写为MIC，又称为传声器。
它的作用是将声音信号转换成电信号，再送往调音台或放大器。
在音响系统中，话筒拾音是第一个环节，所以使用好手中的话筒对每一个音频工作者都是至关重要的。
想要使用好你的话筒，首先你要了解它，熟悉它的特性。
之后，当你要对某种音源进行拾音时，你才会知道要使用什么样的话筒，如何使用它，才会达到令人满意的效果。
一. 话筒的特性1. 话筒的分类根据话筒的特性不同，其分类有很多种。
下面只简单的介绍几种：根据把声音变成电信号的转换方式可分为：动圈式话筒，带式话筒，电容式话筒。
其中电容式话筒又分成真正的电容话筒和驻极体电容话筒。
根据极坐标图可分为：全方向性话筒，单方向性话筒，双向性话筒。
其中单方向性话筒又分为心形话筒，超心形话筒，强心形话筒。
根据不同的用途可分为：人声话筒，乐声话筒，界面话筒，微型话筒，立体声话筒，头戴式话筒。
2. 话筒的性能参数当拿到一只话筒和它的使用说明书后，我们如何来判断这是否是一只性能好的话筒或是否是我们想要的话筒呢？下面我们简单的介绍一下话筒的性能参数。
灵敏度话筒的灵敏度指的是话筒在一定声压级下所能产生多少输出电压。
下面列出了3种类型话筒的灵敏度指标。
电容话筒：5.6mv/pa，动圈话筒：1.8 mv/pa，带式话筒：1.1 mv/pa。
频率响应话筒的频率响应指声波从指定方向入射时，话筒灵敏度随频率变化的特性。
反映灵敏度与频率关系的曲线称为频率响应曲线。
通常用带内不均匀度来表示话筒频率响应的优劣。
不均匀度越小，表示话筒的频率响应越好。
本底噪声本底噪声是话筒本身产生的电噪声或咝咝声。
14dB的本底噪声指标为极好，21 dB时为很好，28 dB时较好，35 dB时则一般。
信号噪声比信号噪声比是话筒灵敏度与本底噪声之间用分贝来表示的差量。
当指标为74 dB时为极好，64 dB时为良好，54 dB时就比较差了。
最大声压级最大声压级是此话筒最大不失真的声压级的值。

二、游戏耳机麦克风的技术参数除了麦克风的类型外，游戏耳机麦克风的技术参数也是评估其通话效果好坏的重要指标。
常见的技术参数包括频率响应范围、灵敏度和阻抗等。
频率响应范围表示麦克风能够传输的声音频率范围，一般来说，频率响应范围越宽广，麦克风的接收声音能力越好。
而灵敏度则表示麦克风对声音的敏感程度，单位为分贝（dB）。
一般来说，灵敏度越高，麦克风接收声音的效果越好。
阻抗则是指麦克风的电阻特性，与耳机的驱动器匹配程度相关，对于通话效果的影响较小。
三、游戏耳机的噪音抑制技术在游戏语音通话中，噪音的存在常常成为影响通话效果的因素之一。
为了提供清晰的通话体验，许多游戏耳机采用了噪音抑制技术。
噪音抑制技术可以有效地过滤掉周围环境中的杂音，使声音更加纯净。
目前市面上常见的噪音抑制技术包括被动噪音抑制和主动噪音抑制。
被动噪音抑制通过优化耳机结构，减少来自外界的噪音干扰。
而主动噪音抑制则通过在麦克风和扬声器之间建立一个反噪声系统，实时监测和抵消环境中的噪音。
四、游戏耳机麦克风的方向性游戏耳机麦克风的方向性也是影响通话效果的重要因素之一。
常见的麦克风方向性有全向麦克风、单向麦克风（心形麦克风、超心形麦克风）等。
4560 CORE Binaural 头戴式麦克风说明书
4560 CORE BinauralHeadset MicrophoneUser’s manual dpa /4560Congratulations on your new 4560 CORE Binaural Headset Microphone.Immersive sound is an emerging market and there are many possible uses for the 4560 CORE Binaural Headset Microphone. The 4560 is an appealing solution for applications such as sound system documentation, soundscape analysis, sound quality assessment, as well as sound for theatrical productions, podcasts and gaming.The 4560 is made from a handpicked stereo pair of 4060 Miniature Omnidirectional Microphones. With the use of our head and ears as natural spacers/shadows and reflectors we can create a sonic 3D print of the sound around us. This is based on the theory of the HRTF, which also means that the recorded material must be listened to via headphones or converted to a relevant 3D format that includes the height information.Learn more: dpa /binaural-recording-techniques The two 4060 mics are mounted on a flexible, unobtrusive headset, which is ergonomically designed to fit comfortably. The headset adjusts easily to fit any ear size as well as head shape.IntroductionCable management and additional adjustment options see: dpa /4560Getting started Adjusting frame sizeTwo sizes of foam windscreens are supplied with the 4560 to secure the mics’ position in the ears and to offer extra damping of wind noise. Gently place the desired size onto the microphones.To decrease the frame size, hold the coils on the headset frame and slowly pull the coils away from each other to the desired size. After making the frame adjustments, starting from the top, smooth the entire braided sleeving back down the cable. Replace the clothing clip.To increase the frame size, hold the cable and frame behind the earhooks and slowly pull the ear hooks away from each other to the desired size.Before adjusting the frame size, you need to loosen the braided sleeving covering the cable. Remove the clothing clip, grab the bottom of the sleeving and pull it gently upwards, smoothing it up the entire length of the cable to make it loose at the top.Make a little loop with the cable so there is enough slack to turn your head from side to side.To make sure the microphones stay in place, use the clothing clip. This relieves the weight of the cable on the headset.Adjusting the cableMounting on the head Make sure the earhooks sit comfortably and securely around the ears.Place the microphones gently in your ear canals. They should not be pressed tightly into the ears because this might affect the sound.0Connecting the 4560Make sure you correctly plug the connections into the right/left device inputs.

头戴式麦克风的正确使用
麦克风在录音室与现场扩音的音效不同：
许多用户看到电视节目中，使用领夹式麦克风（Lavalier Mic）发音的音效非常理想，于是也使用这种麦克风在现场扩音，结果都达不到想象中那么满意的音效。
这不是领夹式麦克风本身质量的问题，而是因为麦克风的佩戴位置距离嘴巴太远，在现场扩音时麦克风会与扩音系统的喇叭产生回授声的物理现象，无法任意提升音量，于是扩音效果不佳。
拉近麦克风与嘴巴的距离，以改善麦克风的扩音音效：
由于领夹式麦克风佩戴在胸前，距离嘴巴较远，输出的音量会大大的降低，若是把扩音机的音量调大，就容易产生回授的哮叫声，这是一般麦克风用户常遇到的难题。
如果要提升麦克风的音量，又不产生回授声，唯一的方法就是利用『麦克风的音量与音源的距离平方成反比』的原理，将麦克风与嘴巴的距离拉近，就可以将麦克风的声音大大的提升。
使用头戴式麦克风，改善现场扩音的音量：
可是问题就在于如何将麦克风固定在嘴巴的附近呢？市面上出现许多设计，『头戴式麦克风』的设计就是其中的解决方法之一。
头戴式麦克风主要目的是提供现场扩音之用，借着佩挂在头上，可以把麦克风音头调整到最靠近嘴巴的位置，让麦克风获得最高的灵敏度，输出最大的音量，改善产生回授声的困扰。
头戴式麦克风音效的难题：
可是新的问题又来了，由于我们的嘴巴在讲话时，对有些发音如含有英文字母的『B、F、P…』或中文的『ㄆ、ㄈ、ㄊ、ㄏ…』等等字音，会由嘴巴发出强烈的『气爆』冲击到麦克风的振动膜，使麦克风产生过荷（Overload）失真，导致喇叭输出强烈的『气爆杂音』（Pop Noise），严重破坏了正常音质，这种现象尤其在麦克风对着嘴巴正面或下巴附近使用时最明显，而且麦克风距离嘴巴越近，气爆杂音也就越严重。
怎样佩戴头戴式麦克风才能展现最佳的音效？
调整佩戴麦克风的姿势，将音头调整在『靠近嘴巴左右两边』的位置，可以降低气爆杂音并获得预期的音量及正常的音质。
头戴式麦克风使用的音头有：全指向性及单指向性两种，前者，因为音头没有指向性，佩戴时只要『把音头调整在嘴巴左右两边，距离嘴角约一个指头的距离，并与嘴角接近垂直的方向』，就可以明显的避免气爆杂音，达到最清晰的音响效果。
后者的音头因具有指向性，在现场演唱时，比全指向性麦克风具有较丰富的低音及较高的动态范围，可展现较富有音乐性（Musical）的音效，但是音头的佩挂位置也相对的更加挑剔。
除了灵敏度会因距离嘴巴的远近而改变之外，音头的近接效应（Proximity effect）与『气爆杂音』的反应也比较敏感。
因此，采用指向性头戴式麦克风在佩戴时，理论上，音头位于嘴巴正前方的音质最好，但是这个位置与全指向性麦克风一样，是最容易受到气爆声的影响而破坏了正常的音质，所以佩戴时最重要的原则，同样是要避开『嘴巴的正面到下巴中间』的位置。
经过实际测试，『把麦克风音头的正面与嘴角保持约一个指头的距离，并与嘴角保持45度左右的水平方向』是最理想的佩挂位置，可以避免气爆声的破坏，又能展现最佳的灵敏度与音质，如果音头的位置超过嘴角的前面，受到气爆声的影响会越大，虽然利用海绵之类的防风罩，可以稍微减少气爆杂音及风杂音的影响，但是多少也会破坏脸部的观瞻及衰减麦克风的高频响应。
如何正确的佩戴头戴式麦克风？
首先要依个人的脸形、头部及耳朵大小，从大、中、小三个耳挂框架选择最适合的尺寸，再选择适合搭配发射器插座的输出联机，将另一端结合到偏爱的音头模块后，装配到框架上的固定座上，戴在头上再调整音头模块的连杆固定位置及连杆的弯曲度，使音头位于嘴角边最适当的位置，因为连杆固定位置可以自由
移动及任意弯曲调整，调整是否适当，对麦克风的使用效果影响非常大，所以初次使用头戴式麦克风者，对耳挂框架大小的选择及连杆的调整要特别用心。
调整音头的位置与方向：在音头模块固定座（A）调整音头连杆（B）的长度，使音头连杆尾端的音头（C）位置不要超过嘴角，再利用可适度任意弯曲的音头连杆，调整音头的水平高度及方向约在嘴角之下附近。
调整音头位置时，最好一边调整，一边利用现场的扩音系统试音，请用中文发音：『丰富！丰富！…』，或英文发音：『PUSH! PULL! ...』，在嘴角边细心的微调音头的位置及方向，直到获得最满意的灵敏度及没有气爆声的最佳音效。
