麦克风混音器使用方法
电脑麦克风回音解决办法
电脑麦克风回音解决办法1、这种情况有时是网络速度太慢造成的，如果你在语音的时候最好关掉视频。
2、不少人在使用麦克风之前，喜欢将音量控制面板中“麦克风”一栏的“静音”选项勾去掉，并且把麦克风音量调到最大。
其实这种做法是错误的，“麦克风”的“静音”选项并不是控制麦克风发声的，而是控制音响和耳机是否反馈麦克风的声音。
所以建议大家在使用麦克风时将“静音”选项选中，这样就可以消除耳机中的杂音和回音，以便得到更好的语音效果。
3、详细设置步骤如下：（1）用鼠标双击windows桌面右下角的“喇叭”形图标，打开“音量控制”窗口。
（2）点窗口主菜单项“选项”（左上角），并选“属性”，打开“属性”对话框。
（3）在“混音器”下拉列表中选择一个混音器。
大多数电脑中只有一个混音器，有的电脑中有两个混音器，一个用于设置录音，一个用于设置播放。
对于只有一个混音器的情况，在“调节音量”下的单选纽中一般有两个有效的单选钮，播放和录音，对于有两个混音器的情况，在“调节音量”下的单选钮中只有一个有效，播放或录音。
4、播放的设置（1）选中“调节音量”下的单选钮“播放”。
（2）将“显示下列音量控制“下的各项全部打勾；（3）点“确定”打开“音量控制”窗口；（4）除了“音量控制”和“波形”下的选择框外，其他选择框全部打勾（静音）。
（5）播放设置完成。
5、录音的设置点窗口主菜单项“选项”（左上角），并选“属性”，打开“属性”对话框。
（1）选中“调节音量”下的单选钮“录音”；（2）将“显示下列音量控制”下的各项全部打勾；（3）点“确定”打开“录音控制”窗口；（4）除了“麦克风”下的选择框打勾外，其他选择框全部不打勾；（5）调节麦克风的滑动条中的滑块来调节录音音量（一般最大）；（6）麦克风高级属性设置；A．如果麦克风设置下，没有“高级”按钮，则点“选项” “高级”（如果为有效状态）B．点“高级”按钮，打开“麦克风的高级控制”对话框；C．如果你麦克风的录音音量很小，建议在“MICBOOST”(麦克风加强)前打勾；D．如果你麦克风的录音的杂音大，建议在“MICBOOST”(麦克风加强)前不打勾7、录音设置完成。

LM-2 Series Remote Mic/Line Mixer/Control ModulesInstallation GuideContentsIntroduction (3)Mounting - mechanical (3)Faceplate Controls and Connections (4)Block Diagram (5)Installation - connections (5)Configuring the Facility Port (7)Connecting multiple LM-2s (7)Local inputs (7)Remote controls (8)LM-2 Priority Operation (9)Mic priority: (9)Full priority: (9)Power considerations (10)The LM-2 is a remote module for use with the following Cloud products:• Z4MK3 and Z8MK3 Zone Mixers• 46-120 and 46-120MEDIA Zone Mixing AmplifiersIt cannot be used with any other Cloud product.NOTE: Unless specifically stated otherwise, all referencesto “LM-2” in this Installation Guide can be taken to applyto all LM-2 mechanical and cosmetic variants.The LM-2 module combines the functions of a remote input connection plate, local audio mixer and a remote control for the host unit’s background music.Inputs for both a microphone and a stereo line signal (for a local music source) are provided, with individual level controls. The stereo channels are summed to mono, and then mixed with the mic input.The remote control facilities are equivalent to those on a Cloud RSL-6 remote control module, and allow selection of background music source and level control for the host’s Zone to which the LM-2 is connected. (Note that the 46-120 and 46-120MEDIA have a single Facility Port, for Zone 1 only.)The LM-2 is connected to the host unit’s Facility Port by a single screened Cat 5 cable with RJ45 connectors. A link connector is provided to permit multiple LM-2s to be installed in the same Zone.LM-2 (UK version)The Cloud LM-2 fits a standard UK-style dual-gang electrical back box. The box used should have a depth of at least 35 mm. LM-2A (US version)The Cloud LM-2A fits a standard US dual-gang electrical ‘J’ box in vertical orientation. The box used should have a depth of at least 1¼”.LM-2D (German/Austrian version)The Cloud LM-2D fits a DIN-standard double-gang back box (requiring 2 x 68 mm dia cut-outs), of the type used in various countries including Germany and Austria. The box used should have a depth of at least 35 mm.1. MIC INPUT – 3-pin XLR3F connector for dynamic microphones. Note that the LM-2 does not provide phantom power.2. LINE INPUT (a) – 2 x phono (RCA) sockets for connection of sources such as CD players, audio mixers, radio micreceivers, etc; suitable for line level signals with a nominal level of 0 dBu.3. LINE INPUT (b) – 3-pole 3.5 mm jack socket for connection of sources such as computers, laptops and digital mediaplayers; suitable for line level signals with a nominal level of +8 dBu. A source plugged into this input will be summed to mono and mixed with any source connected to the phono inputs 2.NOTE: Both stereo line inputs are summed internally to mono; hence, if using a mono source such as a radio mic receiver, only one channel need be connected.4. MIC LEVEL – gain control for mic input. Up to 60 dB gain is available; with the control fully anti-clockwise, the input iseffectively ‘off’.5. MUSIC LEVEL – gain control for whichever line input (2 or 3) is in use. With the control fully anticlockwise, the sourcewill be ‘off’; in the fully clockwise position, 10 dB of gain is provided.6. MIC PRIORITY – default function for this button is to give the microphone input priority over both the module’s lineinput and the background music selected at the host unit. This operation can be modified by jumpers on the rear PCBs. See “LM-2 Priority Operation” on page 9.7. BACKGROUND MUSIC SOURCE – six-position switch selecting which of the host unit’s six Line Inputs will be routedto the Zone to whose Facility Port the LM-2 is connected (usually the Zone where the LM-2 is installed).8. BACKGROUND MUSIC LEVEL – adjusts the background music level in the Zone.NOTE: Switches and internal jumpers will need to be set in the host unit in order for the background music controls 7 and 8 to operate as required. See “Remote controls” on page 8.RJ45 RJ45The LM-2 has two PCBs mounted on the rear of the faceplate. The OUTPUT RJ45 connector is located on the upper PCB while the LINK RJ45 connector is on the lower:LOCATION OF REAR RJ45CONNECTORS(‘DIN’ version illustrated.Sketch simplified;only primarycomponents shown)The LM-2’s OUTPUT connector should be connected to the host unit’s FACILITY PORT for the Zone in which it is installed* with screened Cat 5 cable and shielded RJ45 plugs.LM-2 (UK version illustrated)The maximum total Cat 5 cable length should not exceed 100 m. If further modules are being “linked” together (see below), this figure applies to the overall cable run from the host unit to the “furthest” module in the chain.IMPORT ANT: Because the cables carry low-level audio, only screened Cat 5 should be used, the foil screen of the cable being bonded to the metal screening can of the plugs. If an LM-2 is being installed in very close proximity to the host unit, it may be possible to use ready-made screened Cat 5 “patch” cables of short length. In all other situations, shielded RJ45 plugs should be crimped onto the installed screened Cat 5 cable using the pinout shown below.* There is no reason why the module cannot be connected to the Facility Port of a Zone other than that in which it is installed – though this is likely to be anunusual installation scenario.Configuring the Facility PortThe mic and line inputs on the LM-2 module will be available in the Zone as soon as the module is connected to the host unit’s Facility Port for that Zone. The volume of the mic and line inputs will be determined solely by the level controls on the LM-2 faceplate and unaffected by any of the host unit’s front panel controls.In order for the remote control section (background music source and level controls to operate correctly), the host unit must be set for remote control operation.Z4MK3 and Z8MK3:Set the MUSIC CONTROL button on the host unit’s rear panel to REMOTE (in) for the Zone in use. The button is adjacent to the REMOTE SOURCE + LEVEL connector immediately above the FACILITY PORT. This will disable the host unit’s front panel music source and level controls for the Zone.Sometimes it is desirable to permit remote control of music level but keep music source selectable only on the host unit. In this case, internal jumper J1 on the sub-board for the Zone in use should be moved from ‘SW’ to ‘FR’. This will render the LM-2’s music source switch inoperative, and return source selection to the front panel. See the Z4MK3/Z8MK3 Installation and User Guide for full details and jumper locations.46-120 and 46-120MEDIA:These units only have a single Facility Port, for Zone 1. Thus the LM-2 can only be installed in Zone 1. (If the LM-2 needs to be added to a different Zone in an existing system, this restriction may be simply overcome by swapping outputs and renaming the Zones.)Set the two REMOTE MUSIC CONTROL buttons (LEV and SRC) for ZONE 1 on the rear panel to REMOTE (in). The buttons are immediately below the 4 x 3-pin REMOTE CONTROL PANEL CONNECTORS. This will disable the host unit’s front panel music source and level controls for Zone 1.Sometimes it is desirable to permit remote control of music level but keep music source selectable only on the host unit. In this case, set the SRC button for ZONE 1 back to FRONT PANEL (out). This will render the LM-2’s music source switch inoperative, and return source selection to the front panel. See the 46-120/46-120MEDIA’s Installation and User Guide for full details and jumper locations.Connecting multiple LM-2sT wo or more LM-2s may be installed in the same Zone by employing the LINK connector on the lower rear PCB. The primary purpose of this feature is so that microphones and music sources may be connected into the audio system at different locations within a single Zone (typically one of large area or complex layout).Local inputsWhen modules are “daisy-chained” together in this way, the audio signals from each module are summed together to produce a single mono feed to the host unit. Thus two (or more) microphones may be connected within a zone and either or both used as wished, with individual mic level controls at their respective modules.An internal gating circuit on each module automatically “disconnects” any chained modules which are not in use, to minimise noise contribution. Should this the gate function not be required for any reason, it may be disabled by linking two solder pads on the lower PCB - see page 8. (Remove the lower PCB from the faceplate before attempting to make this link.)This also applies to multiple music sources simultaneously connected (though the possibility of resulting cacophony makes this a less likely scenario!)LM-2 LOWER PCBNOTE: Users should be aware when using simultaneous microphone and/or music sources from multiple linked modules that the operation of the LM-2’s Priority function may become unpredictable, and if the function is enabled, one microphone may disable another, for example. We recommend that the Priority function is not used under these circumstances.Remote controlsWhen modules are linked, only one may act as the remote control for each of the host unit’s background music functions: source and level. The MUSIC SOURCE and MUSIC LEVEL controls 7 and 8 (see “Faceplate Controls and Connections” on page 4) on all but one of the linked modules must be disabled. This is done by moving jumpers J1 and/or J3 on the upperPCB as required.J1J3LOCATION OF JUMPERSThe default setting for J1 and J3 is LOCAL; this enables both the faceplate background music source and level controls. Set both jumpers to LINK to “pass” the remote control functions to the LM-2 connected at the LINK connected.Note that the two functions – background music source selection and background music level – may be disabled individually, so that one LM-2 in a Zone could control the music source and another the music volume.Note that it is also possible to “daisy-chain” standard Cloud RL-1 and RSL-6 remote control plates to the LINK connector. This would be useful if additional background music control points were required in the Zone, but not additional system inputs. Please refer to the T echnical Notes section at for further information on this topic.If the MIC PRIORITY button on the LM-2 faceplate is not pressed, mic and/or line signals connected at the module will be routed to the Zone to whose Facility Port the LM-2 is wired, and heard through the audio system at volumes which can be controlled from the MIC LEVEL and MUSIC LEVEL controls on the faceplate. These locally-connected signals will be mixed within the host unit with any background music currently selected for that zone.Mic priority:The LM-2’s Priority facility has two modes of operation, selected by jumpers on the upper rear PCB. The default mode operates thus: with MIC PRIORITY pressed, a signal at the microphone input will cause the line input signal connected at the same module to “duck” by 30 dB, giving the speaker priority over the music. The attack time (how quickly the music level drops when the mic is used) and release time (how quickly it recovers after the mic signal stops) are pre-set, and optimised for best audible results. The priority control signal is also sent to the host unit, where it additionally “ducks” whichever Line Input is currently selected in the Zone. Thus the LM-2 mic input has priority over both local and global music sources.It is important to note that any Priority functions set within the host unit – e.g., Line 6 Priority or Paging – will operate as normal. However, if Line 6 Priority is selected and active, the Line 6 source will still be ducked by the LM-2’s Mic Priority. Full priority:LOCATION OF JUMPERSLink indicates defaultIf jumpers J2 and J4 are moved from their default settings to the alternative setting, Priority operation changes. When MIC PRIORITY is pressed, the module’s summed output is used to derive the priority control signal that is sent back to the host unit, and the signal is at the voltage required by the host unit to fully mute the background music.The result is that a signal at either the LM-2’s mic input or line input will fully mute the selected Line Input at the host unit, and thus any source connected at the LM-2 will take full priority over the Zone’s background music.As with the default mode, any priority functions set within the host unit itself will still operate normally, though if Line 6 priority is selected and active, the Line 6 source will be overridden by the LM-2 Priority.The LM-2 is powered from the host unit’s FACILITY PORT via the Cat 5 connection. The LM-2 consumes 12 mA of current from the host unit’s power supply.In the majority of installations, the host unit will have ample spare current capacity to power one or more LM-2s. However, installers should note that this may not be case in a very large system with multiple remote modules in several Zones. If there is any doubt about the power capability, please refer to the host unit’s Installation and User Guide where full details of power supply ratings can be found.Should you have any questions concerning the installation and connection of the LM-2, please visit /resources, where you will find additional technical information.LM-2 Installation Guide v1.011Cloud Electronics Limited 140 Staniforth RoadSheffield S9 3HFEnglandT el: +44 (0)114 244 7051 Fax: +44 (0)114 242 5462 email:*************.uk web: Cloud Electronics USA 2065 Sidewinder Drive,Suite 200, Park City,Utah 84060.

Selected Channel LED indicators. Indicate which channels are “on” or “active.”5. Aux In control. Adjusts input for source output level and/or operating conditions.6. Output Level LED meter. Indicates RMS output level of the mixer. “Zero” (0) level isfactory calibrated for an output of +4 dBm into 600 ohms (Master level control fullyclockwise). Can be set for peak output level indication via internal switch (see page 10).7. Priority Pre-select switches (1-4). A switch in the “up” position assigns the respectivechannel priority over the other channels. A priority channel can not be locked out byother channels. Any combination of priority/non-priority selections is allowed.8. Manual mode switch. Setting this switch in the “up” position bypasses all of theSmartMixer’s automatic functions, except limiting and NOMA if selected.9. Lockout LED indicator. Shows when lockout bus is active.10.

Rear panel78Mode 2…Priority Pre-select switches (1-4) DownIn this mode, only one mic at a time can be “on.” The lockout bus shuts down all other mics until the first speaker pauses. As soon as the controlling microphone goes silent, the lockout bus goes inactive and any other mic can come on. This switching takes place without anysyllable-grabbing delay, or pops or clicks. (This mode is known as “First-come-first-served”or “Filibuster.”)This mode is very useful when the gain setting of the overall sound system must be close to the threshold of feedback, and additional microphones coming on could throw the system into feedback. The SmartMixer will not allow multiple microphones to be on at the same time in this mode. The switching is so fast and silent that the meeting can still be completely interactive.Mode 3…One Priority Pre-select switch UpThe selected priority microphone can come on at any time and can mute any other mic that is on (popularly called “The Chairperson” mode).(Note that there may be special circumstances where two or three mics could be set to priority, so those speakers could talk whenever desired, but still mute one or two non-priority mics.)If multiple SmartMixers are used with AT8325/1.0 Link Cables, Priority Pre-select switches on all channels in use will have the control effects described above.The selected priority microphone(s) will mute only those non-priority microphones within the same unit.NOMAThe NOMA is factory set in the “off” position. To turn on the NOMA function, unplug the unit, remove the top cover and change the setting of the switch designated on the circuit board by “SW25” (Figs. 4 and 5, page 11).NOMA serves to maintain overall system gain by proportionately reducing amplifier gain as the number of open microphones increases. In a sound reinforcement system, this can tend to preserve the feedback margin and system stability. However, this action necessarily reduces the sound level of each individual person speaking, which may not be desired. In the end,use of NOMA often comes down to the preferences of the system’s designer and/or operator.Generally speaking, use of NOMA is not desirable in applications such as teleconferencing,recording or broadcasting.Auxiliary InputThe Aux input is an RCA jack accepting auxiliary-level (–10 dBV) input from sources such as tape decks and VCRs. There is no signal processing of the Aux input.Preamplifier GainThe SmartMixer has a substantial gain range, allowing it to accept a wide variety of micro-phones. However, if in some instances higher-output microphones are used for close talking, it may be necessary to reduce the preamplifier gain. This can be done by changing switchsettings inside the unit. With the unit unplugged from its AC source, remove the two screws on each side of the unit and carefully lift off the top cover. Locate the internal switchesdesignated on the circuit board by “SW2,” “SW8,” “SW14” and “SW20” (Figs. 4 and 5, page 11).A “control map” drawing will be found on the inside of the top cover. Changing the settingsof these internal switches will cause a gain reduction of 10 dB for channels 1, 2, 3 and 4respectively.9The preamplifier gain may be reduced further, allowing the SmartMixer to accept line-level sources. Changing the settings of the internal switches designated by “SW3,” “SW9,” “SW15”and “SW21” will cause an input reduction of 50 dB for channels 1, 2, 3 and 4 respectively.Note that the appropriate internal switches can be used in combination for a total sensitivity reduction of up to 60 dB for each channel.Output LevelThe SmartMixer’s output is factory set at line level. Should mic-level output be desired,simply unplug the unit, remove the top cover and locate the switch on the circuit boardmarked “SW26” (Figs. 4 and 5, page 11). Changing the setting of this switch will cause a50 dB reduction in output.Phantom PowerEach of the SmartMixer’s inputs supplies +48V DC phantom power. Should it be requiredto disable the phantom power, simply unplug the unit, remove the top cover and locate the switches designated on the circuit board by “SW1,” “SW7,” “SW13” and “SW19” (Figs. 4 and 5, page 11). Changing the settings of these switches will disable phantom power on channels 1, 2, 3 and 4, respectively. Note that, although they do not require phantom power for operation, most balanced-output dynamic microphones can be used without disabling the SmartMixer’s phantom power.Output Level LED MeterThe Output Level LED meter is factory set to indicate RMS output. Should peak outputindication be desired, simply unplug the unit, remove the top cover and change the setting of the switch designated on the circuit board by “SW27” (Figs. 4 and 5, page 11). “Zero” (0) level is factory-calibrated at +4 dBm into 600 ohms.10Summary of Internal ControlsFunction Ch 1 Ch 2 Ch 3 Ch 4 Output 48V Phantom Power SW1 SW7 SW13 SW1910 dB Input Atten.

To adjust the “off” attenuation ofchannel 1, unplug the unit, remove the top cover and locate the trimpot designated on thecircuit board by “VR3” (Figs. 4 and 5, page 11). It is factory set at approximately 8 dB, theattenuation at the middle of the control’s rotation. When the control is turned fully counter-clockwise, “off” attenuation is approximately 20 dB. Conversely, when the adjustment isturned fully clockwise, “off” attenuation is approximately 6 dB. VR6, VR9 and VR12 control “off” attenuation for channels 2, 3 and 4 respectively.Changing the settings of the switches designated on the circuit board by “SW5,” “SW11,”“SW17” and SW23” will extend the range of “off” attenuation to –40 dB for channels 1, 2, 3 and 4 respectively.Preamp OutputsEach microphone channel has an independent unbalanced preamp output that is separatefrom the main mixer output. This is helpful when it is necessary to record the output of each channel, whether or not it is the active mixer output (as is required, for example, in somecourtroom proceedings). As set at the factory, no gating is applied to these outputs. To gate these outputs, unplug the unit, remove the top cover and locate the switches designated on the circuit board by “SW6,” “SW12,” “SW18” and SW24” (Figs. 4 and 5, page 11). Change the switch position(s) to “Gating” for channels 1, 2, 3 and/or 4 respectively, as desired.Input LimitersIndependent, adjustable limiters are available on all mic channels. To adjust the limiterthreshold of channel 1, unplug the unit, remove the top cover and locate the trimpot designated on the circuit board by “VR2” (Figs. 4 and 5, page 11). It is factory set at approximately 0 dB RMS. When the control is turned fully counter-clockwise, limiter threshold is approximately –10 dB RMS. Conversely, when the adjustment is turned fully clockwise, limiter threshold is approximately +10 dB RMS. VR5, VR8 and VR11 adjust limiter threshold for channels 2, 3 and 4 respectively.Changing the settings of the switches designated on the circuit board by “SW4,” “SW10,”“SW16” and SW22” will turn off the threshold-limiting function on channels 1, 2, 3 and 4respectively.Force-on/Force-offTo activate force-on/force-off, install a closure between the appropriate pin and GroundReference on the External Control connector on back of unit.12External Control Connector PinoutPin 1 Channel 1 force off Pin 8 Channel 4 force on Pin 2 Channel 2 force off Pin 9 Channel 1 TTL out Pin 3 Channel 3 force off Pin 10 Channel 2 TTL out Pin 4 Channel 4 force off Pin 13 Ground reference Pin 5 Channel 1 force on Pin 14 Channel 3 TTL out Pin 6 Channel 2 force on Pin 15 Channel 4 TTL out Pin 7 Channel 3 force onDriving LampsGCVDriving Logic GatesEquivalent Output Circuit for ControlVoltage Out Relay Driver Control Voltage OutWhen a microphone channel turns “on,” as indicated by a Selected Channel LED on the front panel, the channel’s associated Control Voltage Out goes “high” (+4 VDC). See chart on page 12 for pin connection. This signal can be used to light indicator lamps, switch speaker zones on and off, select video cameras, etc. The control voltage should not be connected directly to an inductive load such as a relay coil, as damage to the mixer may result. Several interface circuit possibilities are shown in Figure 6 below.Figure 6. Control interface examples.13Daisy-chaining MixersWhen more than four microphones are needed, it is possible to daisy-chain multipleSmartMixers together through the Link In/Out connectors on their back panels (Fig. 2).Connect Mixer #1 Link Out jack to Mixer #2 Link In jack, etc. Mixer #1 output contains onlyaudio from the first four microphones; Mixer #2 output then contains audio from all themicrophones plugged into Mixer #1 and the microphones plugged into Mixer #2. The lastmixer in the chain contains audio from all preceding mixers. The combined output is thentaken from the last mixer in the chain. Because lockout information is passed between mixersthrough Link In/Out, the last-microphone-on condition is not violated. Thus only onemicrophone per installation will stay on when no one is speaking.Note that one or more mixers can be switched to “Manual” mode without affecting theautomatic operation of any other mixers in the chain.NOMA information is passed between AT-MX351 mixers through Link In/Out. If AT-MX351mixers are linked with AT-MX341 and/or AT-MX341a mixers, the NOMA function will passthrough the AT-MX341(a) models but their mics will not be included in the NOMA calculation.Rack MountingProvided with each mixer are two rack ears and six self-tapping screws to attach the ears tothe unit, which allow the unit to be mounted in a 1U rack space.Security CapsFor permanent installations where microphone selections, positions and acoustic conditionsare constant, it may be advantageous to remove the front panel knobs and install securitycaps to prevent unauthorized adjustments. To install, simply press the caps into place,covering the desired control(s). The system should be tested carefully before installing thesecurity caps because they are intended to be “permanent” and are very difficult to remove.If removal of installed security caps becomes necessary, unplug the mixer, remove the twoscrews on each side of the unit and remove the top cover. Then remove the nine screws thatattach the front panel: six on top and three underneath. Remove the front panel. With thepanel removed, the two locking tabs on each security cap can be accessed. The cap can bereleased by carefully squeezing the two tabs together.1415One-Year Limited WarrantyAudio-Technica brand products purchased in the U.S.A. are warranted for one year from date of purchase by Audio-Technica U.S., Inc.

麦克风混音器怎么调
麦克风混音器怎么调麦克风混音器是一种常见的音频设备，用于将多个麦克风的声音混合并调整为理想的音频输出。
混音器的调整可以使得演出、录音等音频活动的效果更加出色。
本文将介绍麦克风混音器的基本调节方法和一些常见的技巧。
基础调节1.连接麦克风和音频设备：首先，将麦克风通过音频线与混音器相连，并将混音器与扬声器或录音设备相连。
确认连接无误后，打开混音器和扬声器/录音设备的电源。
2.调整音量控制：调节混音器上的音量控制旋钮，使得各个麦克风的音量适中。
可以根据需要，逐个调节各个麦克风通道的音量，确保声音的平衡。
3.音频效果处理：许多混音器都提供了一些常见的音频效果处理功能，如均衡器、压缩器、反馈抑制器等。
通过调节这些效果处理功能，可以对声音进行进一步的调整和改善，使声音更加清晰、饱满。
高级调节技巧1.PFL/AFV功能：混音器上通常会有PFL（Pre-Fader Listening）和AFV（After-Fader Listening）按钮。
PFL可用于在调节前预览某个通道的音频信号，AFV可用于在调节后预览某个通道的音频信号。
这些功能可以帮助你更准确地调节每个通道的音量和音质。

High Definion Audio声卡麦克风的相关设置和详细图解
HD Audio 声卡麦克风的相关设置和详细图解注：不同的HD声卡设置界面可能稍有不同，以下图片仅供参考，具体按实际样式查找类似设置路径。
注：此项问题有可能只涉及主机前置（前面）的麦克风接口，用主机箱后面的麦克风接口也许不需要进行设置。
1.点击屏幕右下角红色小喇叭（如图），或是依次打开控制面板-Realtek高清晰音频配置2.在弹出的设置面板里选择混频器3.点击如图所示按钮向前移动4.直到看见 Front Pink in 和 Rear Pink in或者是麦克风5.把红色的叉叉取消掉，然后把音量调大6.大家可以发现上图（ALC880）的录制里的“线路音量、麦克风音量、立体声音量”都可以单独调节，因为ALC880在Recording 的部分，是Selector ,也就是同时间只有一路可以录，所以我们可以个別定义每一路的音量，但现在ALC 861/883等芯片属于Sumation架构，也就是说可以同时间unmute 好几路（例如同时间录Line-In /Mic-In ...）让信号进来ADC, 也就是因为这样，我们只能透过ADC这边的单一Gain Control来录信号。
ALC 861/883录制调节如下图：首先把你要使用的如“线路音量、麦克风音量、立体声音量”的叉叉取消掉7.然后通过旁边的录制旋钮来调节音量大小08.设置后效果如图如果觉得麦克风音量小可以进行09-11步骤，或者直接跳到12步9.点击混频器麦克风设置里面如图的小按钮10.钩选麦克风增强11.这时麦克风音量会明显增大，但伴随有噪声，调节如图重放，可减少噪声12.点击音频IO13.点击设置按钮14.在弹出的对话框如下设置（中英文一样）15.设置好后留意面板里面是否如图显示，如果是则进行如下16-18步骤设置，没有则跳到19步16.点击面板的输出设置17.在弹出的设备类型设置里把音源输入改为音源输出18.确定后面板里应该如图显示如果觉得前置耳机音量小可以进行19-11步骤19.点击如图面板的输出设置20.设置类型为耳机21.设置后应该如下图显示，这时，耳机的音量明显增大了如果没有上面HD音频控制面板请看下图1：首先请双击喇叭图标在点击录音控制面板的选项=》属性，在属性页面上可看到混音器选项，点击右边下拉箭头选择录音控制选项Realtek HD Audio Input,此时会出现录音控制相关菜单，点确定后弹出录音音量调节画面，见下图：默认状态第一项总的录音控制音量为最小，后3项为灰色不可调，这是由于HD 声卡特性，智能控制，这是正常的，请不用担心~~ ^_^ ！请把第一项总的录音控制音量调到最大，后面3项下面静音处打勾的给去掉，现在后置MIC就可以正常使用了！在使用 Realtek ALC880 HD Audio 声卡的系统中，如何使用前置或后置麦克风接口进行录音和语音聊天？文章简介本文介绍了如果设置 Windows 选项，在使用 ALC880 HD Audio 的系统中，用机箱前面板的麦克风接口（简称 MIC ）或机箱后面板的麦克风接口来进行录音。
声卡的音频编辑和混音器使用技巧
声卡的音频编辑和混音器使用技巧在当今的数字音频时代，声卡已经成为我们进行音频创作和处理的重要工具。
无论是录制音乐、制作播客，还是进行视频配音，掌握声卡的音频编辑和混音器的使用技巧都能让我们的作品质量更上一层楼。
接下来，让我们一起深入探讨这些实用的技巧。
首先，了解声卡的基本功能和设置是至关重要的。
声卡不仅负责将声音信号转换为数字信号，还能对输入和输出的音频进行各种处理和控制。
在安装好声卡驱动程序后，我们需要进入声卡的设置界面，根据实际需求调整采样率、位深度和缓冲区大小等参数。
较高的采样率和位深度可以提供更清晰、更准确的音频质量，但同时也会增加系统资源的消耗。
因此，需要根据电脑的性能和具体的应用场景进行平衡选择。
音频编辑方面，剪辑和修整音频是常见的操作。
在选择音频编辑软件时，要考虑其功能是否满足需求以及操作的便捷性。
对于简单的剪辑工作，如去除不需要的部分、分割音频片段等，大多数软件都能轻松胜任。
但如果需要更复杂的处理，如音频特效的添加、音频的拉伸和压缩等，就需要选择功能更强大的专业软件。
在进行音频剪辑时，精确的选择工具是关键。
我们可以通过设置起始点和结束点来准确地选取要处理的音频段落。
同时，利用淡入淡出效果可以使音频的过渡更加自然，避免出现突兀的截断感。
另外，消除噪音也是音频编辑中经常遇到的问题。
通过软件中的降噪工具，我们可以有效地减少背景噪音，提高音频的清晰度。
混音器在音频处理中起着核心作用。
它允许我们对多个音频轨道进行音量、平衡、声像等方面的调整。
在开始混音之前，要先对各个音频源进行清晰的分类和规划。
例如，将人声、乐器、背景音乐等分别放置在不同的轨道上，以便进行独立的控制。
音量调整是混音中最基本也是最重要的操作之一。
要确保各个音频元素之间的音量比例协调，突出主体声音的同时，也不能让其他声音被完全掩盖。
平衡调整则用于控制左右声道的音量分布，以营造出更具立体感的音频效果。
声像的设置可以让声音在立体空间中定位，比如将吉他声音放在左边，鼓的声音放在右边，从而增强音频的层次感。

麦克风使用的注意事项
养成良好的使用习惯，才能最大程度的发挥出其应有 的性能。 ①测试话筒时不能吹话筒或者拍话筒。应用语言或者“喂” 等试音。因为急速气流特别容易损坏拾音器。 ②演出中话筒随用随开。不用时及时关闭话筒上的哑音开 关，这种良好的习惯可以防止杂音的混入。 ③不要将话筒对准音箱。这样做极容易引起声反馈，轻者 影响听众心情，重者烧毁音箱高音。 ④不要用手捂住话筒使用。这样做容易发生声反馈，而且 出来的声音发混不清晰，并且极易引起过载。 ⑤手持话筒尽量将话筒稍低于嘴，这样做可减少喷麦声的 发生。

调音台
概述
调音台实际上是一个音频信号混合控制台(Audio Mixing Controler)，也称作调声控制台。它是包括录 音、扩声等音响系统的控制中心，它不仅是声音信号 的调度司令台，而且是各种警示信号、监听信号的控 制司令台。通常我们所说的调音，其中一个主要步骤 就是根据声源(或者说节目)的特点对调音台进行操作。 调音台可以接受多路不同阻抗、不同电平的输入声源 信号，并对这些信号进行放大及处理，然后按不同的 音量对信号进行混合、重新分配或编组，产生一路或 多路输出。通过调音台还可以对各路输入信号进行监 听。

麦克风混音器使用方法
经常进入聊天室的朋友都知道有一些聊友在唱歌的时候混音效果出奇的好听今天我就拿出一个不错的混音效果器与大家共同分享
这个软件应该是国人网友自己编制的无从考证我也是偶尔发现。
其软件小巧精悍只有3个文件虽然说设计实时Mic混响功能并不是什么复杂的工作但是之前却没有人能或许是愿意做这个软件。
软件资源占用小但功能很丰富里面可以选择不同的混响方式实用性非常强而且操作也非常的简单
首先点击软件的开始这样我们对着mic说话就可以听到自己说话的声音。
需要注意的是所有的录音声卡都要选择录音混和的功能每个卡的
控制台在这个叫法上各不相同有的是mixer有的是叫混合我用的是很普通的话筒在电脑上显示是STEREO MIX。
解压之后把麦克风混响效果器这个文件夹和里面的文件拷到C:/Program files目录内打开找到echoXP按右健创建快捷方式把它拷到桌面上即可。
设置方法是:
1.先在选择里填写你喜欢的记录名称比如慢歌那么你设置混响度的时候就可以设置大一点快歌则设置混响度小一点
2.输入增益标准在----9~13之间根据你机器和麦的效果自由调节。
为了能自己听见自己唱歌时候混响声音效果你需要把输出增益设置成和输入增益一样
3.反馈和变调都设置成零混响音量根据个人机器和个人爱好调节。
4.最后别忘记点一下软件界面正上方“打开设置”左侧那个像个小软盘摸样的按扭记录一下你的设置这样下次用的时候就不用再调整一次了
5. 点一下“开始”按钮这个软件就可以开始工作了
最后提醒各位在语音聊天到里使用这个软件之后可能有人说你的声音很美你得声明自己使用了混响效果软件如果欺骗网友造成了感情纠纷之类的事儿本软件的作者和推荐使用者不负任何责任

效果如何啊一定还要结合伴奏音乐和麦声音大小调节哦
还给大家介绍一种效果吧。
试试如何
1、在选择中选“Double Echo”模式即双混响模式。
2、将输入增益设置成80 输出增益设置成100 反馈设置成30 变调设置成0
3、其他操作同上。
大家也可根据自身设备和个人喜好来制定一个自己的参数以下是一些小窍门。
1、先在选择里填写你要预设的混响参数方式名称比如慢歌一你设置混响度时就设置大一点如果是快歌就设置混响度小一点
2、输入增益参数设置在9~13之间根据你机器和麦的效果可以自由调节为了能自己听见自己唱歌时候混响声音效果你需要把输出增益设置成和输入增益一样
3、反馈参数设置在-11根据个人爱好调节变调设置成零录音控制混响音量根据个人机器和个人爱好调节。
4、最后别忘记点一下打开设置左边的小磁盘按扭保存你的设置这样下次用的时候就不用再调整一次了。
