behringer调音台使用(图解)个人 2009-09-06 09:50 阅读898 评论0字号:大中小Behringer UB1622FX调音台作为一个现代乐手,经常会见到调音台。
就是那种有无数旋钮,还有各种开关,看上去样子很吓人的设备。
一个号称音响师的家伙躲在调音台后面,也不知在忙些什么。
如果他是个高手,你的演出会非常爽!或许你很好奇,但是不会介意自己不会使用调音台——那是专业设备嘛!不会用是应该的。
不过现在越来越多的朋友想在家里给自己录小样,开始玩电脑音乐。
于是总会使用到各种调音台。
什么模拟的、数字的,音频接口里也可能有内置的调音台界面,还有那些似乎更加摸不着头脑的音频软件的调音台。
总之到处都会找到调音台的影子。
很多朋友觉得调音台很复杂,弄不懂。
搞了半天甚至没有声音,郁闷!或者不懂原理,错误的使用调音台,使它没有发挥应有的作用。
想要学习一件事物,我们首先应该知道这个东西到底能够作些什么!我们能用调音台做些什么事情呢?大致可以有如下几项:一. 调音台能够放大输入通道的信号,并且调整输入声音的均衡(EQ),甚至其他效果,比如压缩等等二. 调音台可以把很多声音的混合起来组成一个立体声!三. 调音台能为乐手和演员“返送”监听。
四. 调音台协助效果器为各个通道添加混响、延迟等效果五. 调音台把各通道的声音发送给多轨录音机或者音频接口分轨录音六. 调音台能够可以让录音师很方便的监听所有通道的声音,并且并不干扰这些通道。
实践是学习调音台的最好方法。
我们以市场上比较常见的Behringer UB1622FX模拟调音台为例,介绍调音台的基本功能和使用方法。
这个UB1622FX调音台虽然体积不大,但是功能比较全,还内置了一个数字效果器。
首先声明我不是Behringer公司的“托儿”,我只想用一个具体的例子让大家了解调音台的一些基础知识!知识是相通的,只要掌握了调音台的基础知识,就可以很快掌握和使用各种各样的调音台,无论是模拟的还是数字的,甚至是那些虚拟的调音台,都能很快上手。
Manual-1MLM 103MIC/LINE MIXEROPERATORS MANUAL WEAR PARTS:This product contains no wear parts.MLM 103 CONNECTIONINPUTSThe MLM 103 has ten balanced Euroblock Inputs. Use only shielded cable. For best noise rejection use two-conduc-tor-plus-shielded wire, even for unbalanced operation.Connect the non-inverting (positive) audio lines to the “+”terminals, and the inverting (negative) lines to the “–”terminals. Connect the shields to the “ground” terminals.For those installations where the MLM 103’s internal shield-to-chassis connection causes interference, connect the shields directly to chassis PEM nuts directly above each pair of Euroblock connectors. Be sure to bite through the paint with the star washer and keep the shields wrapped around the audio conductors as mush as possible. For the “theoretical”best ElectroMagnetic Interference (EMI) immunity, connect the shields at both ends of the cables. (For more informationon connections, see RaneNote 110, “Sound System Intercon-nection” later in this manual or on Rane’s web site.)MONO INPUTS 1-6 can accept either mic or line level sources. When connecting line level signals, push the rear panel button in for LINE. For mic signals, be sure the button is in the MIC (out ) position.STEREO INPUTS 7/8 and 9/10 accept line level stereo and mono sources.OUTPUTSThe MLM 103’s OUTPUTS (and DIRECT OUTPUTS)are balanced. The same wiring conventions as the Euroblock Inputs apply.QUICK STARTIf you don't get any further, at least read this section to get the best gain structure out of the MLM 103.INPUTS 1 through 6 may be microphone or line level. The choice between the two is made by setting the Input’s LINE push-button on the rear panel.Push the PHANTOM POWER button (when needed) for each pair of Inputs.Using a screwdriver, adjust the TRIM for each Input so that the front panel OL LED illuminates only occasionally during extreme peaks. The three-band Equalizer settings will influence this, so keep an eye on the OL when making EQ adjustments. Now adjust the LEVEL for each Input.Assign each Input to the desired Output by pushing any combination of the A , B , or AUX ASSIGN buttons.INPUTS 7/8 and 9/10 are stereo line level Inputs.Assign each stereo input to the desired output as follows:When the A/B ASSIGN button is engaged and the MONO button is not engaged, INPUT 7 (or 9) is routed to the A Output, while INPUT 8 (or 10) is routed to the B Output.When the both the A/B ASSIGN and MONO buttons are engaged, both Inputs of 7/8 (or 9/10) will route to both the A and B Output.The AUX ASSIGN button is always a mono mix of the stereo channel.FRONT PANEL DESCRIPTIONቢ Equalizer level controls are used to contour the frequency response of the desired Input.ባ Mic/Line OUTPUT ASSIGN buttons. When the A button is engaged, the Mic/Line Input’s audio is routed to Output A.When the B button is engaged, the Mic/Line Input’s audio is routed to Output B. When the AUX button is engaged, the Mic/Line Input’s audio is routed to the Aux Output. Any (or all) of the ASSIGN buttons can be engaged simultaneously.ቤ Mic/Line INPUT LEVEL controls 1-6 determine the amount of signal to be delivered to the assigned Outputs.ብ Mic/Line OVERLOAD LED monitors the signal level before and after the Equalizer.ቦ Stereo Line OUTPUT ASSIGN buttons. When the A/B assign button is engaged and the MONO button is not engaged, Input 7 (or 9) is routed to the A Output, while Input 8 (or 10) is routed to the B Output. When both the A/B ASSIGN and MONO buttons are engaged, both Inputs of 7 and 8 (or 9 and 10) will be routed to both the A and B Output. The AUX ASSIGN button is a mono mix of the stereo Inputs.ቧ Stereo Line INPUT LEVEL controls 7/8 and 9/10 determine the amount of stereo or mono line signal to be delivered to the assigned Outputs.ቨ Stereo Line OVERLOAD LED monitors the signal levels after the Equalizer and after the line gain stage.ቩ Output Meters indicate the overall levels of Outputs A, B and the AUX Output. The Meters are “peak hold”.ቪ A, B and AUX OUTPUT LEVEL controls set the Output Level for A, B and AUX Outputs.ቫ POWER LED lights whenever adequate power is applied to the unit.Manual-2Manual-3REAR PANEL DESCRIPTIONቢ MIC/LINE INPUT TRIM controls 1-6 adjust the input gain of the Mic/Line Inputs. The gain range for Mic level is 15 to 60 dB. The gain range for Line level is 0 to 12 dB.ባ LINE/mic INPUT buttons 1-6 switch the sensitivity and input impedance for either a microphone or line input. Mic level is selected when the button is in the “out” position. Line level is selected when the button is in the “in” position.ቤ MIC/LINE INPUT connectors 1-6 are balanced Euroblocks that connect either microphone or line signals.ብ PHANTOM POWER button applies 12 volt phantom power to each pair of Mic/Line Inputs.ቦ STEREO LINE INPUT connectors 7/8 and 9/10 are pairs of balanced Euroblock connectors, to accommodate stereo or mono line level signals.ቧ PRE/post MIX LEVEL DIRECT OUTPUT buttons . When this switch is in the “in” position, the Direct Output signal is not affected by the Input’s Level control. When this switch is in the “out” position, the Direct Output signal is affected by the Input’s Level control.ቨ DIRECT OUTPUTS are balanced Euroblocks that directly connect each Mic/Line Input signal to other audio devices as needed. These Direct Outputs are post-Equalizer.ቩ A, B and AUX OUTPUT connectors. One 6-post balanced Euroblock connects the A mix and the B mix to other audiodevices as needed. The other 3-post balanced Euroblock connects the AUX mix to other audio devices as needed.Manual-4©Rane Corporation 10802 47th Ave. W., Mukilte o WA 98275-5098 TEL (425)-355-6000 FAX (425)-347-7757 WEB 104195MLM 103 OPERATIONMONO MICROPHONE/LINE LEVEL INPUTS 1-6The rear-panel MIC/LINE INPUT TRIM adjusts the input gain of these Inputs, before the front panel LEVEL controls.When an Input’s LINE/mic button is in the “out” position (Mic Level), the gain range is 15 to 60 dB. When an Input’s LINE/mic button is in the “in” position (Line Level), the gain range is 0 to 12 dB.First, input some “loud” source material (like a pop metal or disco CD, give a kid a mic, etc.) Then, using a screwdriver,adjust the TRIM for each Input so that the front panel OL LED illuminates only occasionally during extreme peaks. The 3-band Equalizer settings will influence this, so keep on eye on the OL when making EQ adjustments.Push the PHANTOM POWER button (when needed) for each pair of Inputs. If the LINE/mic button is engaged (Line Level), Phantom Power is automatically defeated for that Input. The PHANTOM POWER button activates 12 volts which is sufficient power for all but the most esoteric condenser mics. If in doubt, check the manufacturer’s microphone specs.Assign each Input to the desired Output by pushing any combination of the A, B or AUX ASSIGN buttons.The LEVEL of each Input can now be adjusted as needed without danger of blowing your speakers, or scaring the neighbors, whichever you deem worse.STEREO LINE LEVEL INPUTS 7/8 and 9/10When a stereo source (CD, DVD, cassette, etc.) isconnected to Inputs 7/8 (or 9/10), the routing is as follows:When the A/B ASSIGN button is engaged and the MONO button is not engaged, INPUT 7 (or 9) is routed to the A Output, while INPUT 8 (or 10) is routed to the B Output.When both the A/B ASSIGN and MONO buttons are engaged, a mono mix of INPUTs 7/8 (or 9/10) will be routed to both the A and B Outputs.The AUX ASSIGN button is always a mono mix of the stereo channel.OUTPUT LEVELSAfter all of the Mic/Line and Stereo Input Levels have been adjusted and routed, adjust the OUTPUT faders so the Meters peak average around 0 to +2.。
AMBE-1000 用户手册版本1.0南京梧桐微电子中心1. 概述根据对语音构成的分析,应运而生了多种对音频信号的压缩编码算法,如CELP、RELP、VSELP、MP-MLQ、LPC-10、MBE等,它们通过不同的算法,实现对音频信号的压缩。
这些压缩编码算法的压缩率、语音质量各有所长,其中美国DVSI(Digital Voice System Inc)公司提出的先进多带激励AMBE (Advanced Multi-Band Excitation)压缩编码算法是其中的杰出代表。
AMBE是基于MBE技术的低比特率、高质量语音压缩算法,具有语音音质好和编码速率低等优点,AMBE-1000是一款高性能多速率语音编码/解码芯片,语音编码解码速率可以在2400~9600bps之间以50bits的间隔变化,即使在2400bps的时候,仍能保持自然的声音质量和语音可懂度。
在芯片内部有相互独立的语音编码单元和解码单元,可同时完成语音的编码和解码任务。
并且所有的编码和解码操作都能在芯片内部完成,不需要额外的存储器。
这些特性使它非常适合于数字语音通信、语音存储以及其它需要对语音进行数字处理的场合。
2. AMBE-1000应用设计的概述2.1 基本操作AMBE-1000最基本的组成部分就是一个编码器和一个解码器,两者相互独立。
编码器接收8KHZ采样的语音数据流(16bit线性,8bit A律,8bit u律)并以一定的速率输出信道数据。
相反,解码器接收信道数据并合成语音数据流。
编码器和解码器接口的时序是完全异步的。
AMBE-1000采用A/D-D/A芯片作为语音信号的接口。
输入输出的语音数据流的格式必须是相同的(16bit 线性的,8bit A律,8bit u律),信道接口采用8位或16位的微控制器。
芯片可选择的功能包括回声抵消,VAD(语音激活检测),电源模式,数据/前向纠错率的选择等,这些功能由外围管脚或输入到解码器的命令帧来决定。

Input sensitivity is variable from200 Millivolts to 8 volts. Clockwise increases sensitivity. Counterclockwise decreasessensitivity. The amplifier can be driven to full power with a wide range of signal levels.A lower signal level will require increased sensitivity for full power. A higher signal levelwill require decreased sensitivity. Av oid setting sensitivity lower than necessary as this would introduce unwanted distortion.This control is used to set the desired low pass frequency (50 ~ 150HZ).The filter acts to cut-off frequencies above the set-point. In general, the selectedfrequency should closely match the resonant frequency of the speaker box.By using the bass boost function, bass notes at 35Hz - 80Hz are emphasized as much as 18dB.PHASE SHIFT SWITCH (0 AND 180 DEGREES):Allows you to change the phase of your subwoofer from 0 to 180 degrees to helpcompensate for timing differences between drivers.6Variable Subsonic Filter (15Hz - 40Hz) :The Subsonic filter will roll off all of the unwanted frequencies below 15Hz - 40Hz.This will allow the amplifier to use that wasted power on the audible bandwidth.These inputs are for signal cables from the source. Always use high quality shieldedRCA cables.the first amplifier, then using the line out RCA jacks as the feed to the next amplifier.Adjust the crossover for your chosen installation method.LOW: Low pass filter-only bass tones(50Hz-150Hz)go to speakers. Use with woofer or sub-woofer . FULL: No filter-all tones go to speakers. Use with full-range speakers, or with external crossovers. HIGH: High pass filter-blocks very low tones(50Hz-600Hz)from the speakers.CH4Due to the power requirements of the Amplifier, this connection should be made directly to the positive(+) terminal of battery. For safety measure, install an in-line fuse Holder (not included) as close to the battery positive(+) terminal as possible with an ampere rating ; not to exceed total value of fuses in Amp.PWR(Power): This GREEN LED will illuminate when the amplifier is turned "ON".If it fails to illuminate, check the power connections to the Amplifier and fuses.PROT(Protection): The amplifier protection circuitry will disable the amplifier if input overload, short circuit or extremely high temperature conditions are detected. When the protection mode is in operation, the LED indicator on the side panel will be illuminated, indicating the amplifier has gone into a self-preservation mode.If you observe that the Protection LED is lit, please check the system carefully to determine what has caused the protection circuit to engage. The amplifier can be reset by turning the remote power off and then on again. If the amplifier shut down due to a thermal overload condition, please allow it to cool down before restarting. If the amplifier shut down becauseof an input overload or short circuit, be sure to repair these conditions before attempting to power up the amplifier again.Controls & FunctionsThe mounting position of your Amplifier will have a great effect on its ability to dissipate the heat generated during normal operation.Under normal conditions, the heatsink will dissipate sufficient heat to avoid thermal shutdown. However please do not install the amplifier in a wooden box or similar device as this will prevent heat dissipation into the atmosphere.Temperatures in car trunks have been measured as high as (155'F) in the summer time. since the thermal shut-down point for the amplifier is (158'F) it is easy to see that it must be mounted for maximum cooling capability. To achievemaximum advantage of convection air flow in an enclosed trunk, mount the amplifier in a horizontal position.Cooling requirements are considerably relaxed when mounting inside the passenger compartment since the driver will not often allow temperatures to reach a critical point. Floor mounting under the seat is usually satisfactory as long as there is at least1 inch of clearance (2.54 cm) above the Amplifier's fins for ventilation.A. Select a suitable location that is convenient for mounting, is accessible for wiring. And has ample room for air circulation and cooling.B. Use the amplifier as a template to mark the mounting holes.

turn red to indicate clipping any time the audio signal exceeds acceptable levels. These clipping indicators will appear regardless of what mode the Touch Panel is currently operating in.Direct MonitoringDirect Monitoring(DM)is a key feature of the Connect AUDIO2/4.It enables you to monitor audio input dir-ectly from the Connect AUDIO2/4interface without the latency introduced when monitoring the same sig-nal through your DAW.DM offers Mono and Stereo modes and provides Rotary Dial control to balance the level between your audio input(s)and the computer output.How to Enable Direct Monitoring1.Touch Direct on the Touch Panel.The Direct LED indicator will display green and initialize in Monomode by default.2.Select the inputs(1,2,or both)to be monitored.e the Rotary Dial to adjust the balance between audio from the input(s)and USB audio. Working with Direct Monitoring: Mono/Stereo ModesWhen you first initialize DM,it will be enabled in Mono Mode by default.If both inputs are enabled,there will be no panning between audio sources.Toggling DM to Stereo Mode allows you to auto-pan Inputs1 and2to the Left and Right sides of the stereo spectrum and enables clearer monitoring of multiple sources.With Direct selected on the Touch Panel Display,Direct Monitoring can be toggled to Stereo Mode by touching the48V/Inst button.The Direct LED indicator will change from green to red,indicating that DM is now operating in stereo.Figure3:Toggling DM from Mono to Stereo ModeRefer to the Direct Monitoring States reference section of this manual to view all the possible DM con-figurations and their respective audio routing.Working with Direct Monitoring:Adjusting the Input/USB BalanceWith Direct Monitoring enabled,the meters on the Touch Panel Display toggle to show the respective Input(left meter column)and USB(right meter column)levels.Moving the Rotary Control Dial adjusts the balance between the two.l Rotate the dial clockwise for more USB signal in the monitor mixl Rotate the dial counter-clockwise for more Input signal in the monitor mixFigure4:Adjusting the Direct Monitoring balanceAdditional Notes About Direct Monitoringl The Direct Monitoring LED indicator will change to orange any time you press the In or Out buttons to make adjustments.This indicates that Direct Monitoring is still enabled,but not available for edit-ing.Headphone Source SelectionHeadphone Source Selection is a feature of the Connect AUDIO2/4that allows you to easily switch between the computer output channels being monitored on the headphones.One touch switches the headphone source between channels1/2and channels3/4.Note that channels1/2are always routed to the analog outputs on the back panel,regardless of the headphone source selec-tion.To change headphone sources,press the1/2_3/4button on the Touch Panel.l indicates that output pair1/2is selectedl indicates that ouput pair3/4is selectedTroubleshootingI don't hear any sound from the speakers or headphones connected to the interfaceMake sure that you have set up output levels on the unit.Verify that the output pair over which your DAW is transmitting audio is selected on the Touch Panel.I’ve turned on direct monitoring but I'm only hearing the computer output,not the analog input.Verify that you have selected one or more of the analog inputs for monitoring.If neither input is selected, you will only hear the computer output.Refer to the Direct Monitoring section for more information.I have a device connected to the MIDI DIN connectors,but I'm not seeing it on my computer.Verify that the MIDI DIN connections are not reversed.MIDI Out on the controller should be connected to MIDI In on the interface,and vice-versa.The interface is not powering up or is turning ON and OFF again.Verify the USB cable and the USB port power.The USB port may not be providing sufficient power.The cable may be too long or of insufficient quality to support the power supply current.Reference: Audio SpecificationsDigital Performancel24bit resolutionl

AMBE-1000 用户手册版本1.0南京梧桐微电子中心1. 概述根据对语音构成的分析,应运而生了多种对音频信号的压缩编码算法,如CELP、RELP、VSELP、MP-MLQ、LPC-10、MBE等,它们通过不同的算法,实现对音频信号的压缩。
这些压缩编码算法的压缩率、语音质量各有所长,其中美国DVSI(Digital Voice System Inc)公司提出的先进多带激励AMBE (Advanced Multi-Band Excitation)压缩编码算法是其中的杰出代表。
AMBE是基于MBE技术的低比特率、高质量语音压缩算法,具有语音音质好和编码速率低等优点,AMBE-1000是一款高性能多速率语音编码/解码芯片,语音编码解码速率可以在2400~9600bps之间以50bps的间隔变化,即使在2400bps的时候,仍能保持自然的声音质量和语音可懂度。
在芯片内部有相互独立的语音编码单元和解码单元,可同时完成语音的编码和解码任务。
并且所有的编码和解码操作都能在芯片内部完成,不需要额外的存储器。
这些特性使它非常适合于数字语音通信、语音存储以及其它需要对语音进行数字处理的场合。
2. AMBE-1000应用设计的概述2.1 基本操作AMBE-1000最基本的组成部分就是一个编码器和一个解码器,两者相互独立。
编码器接收8KHZ采样的语音数据流(16bit线性,8bit A律,8bit u律)并以一定的速率输出信道数据。
相反,解码器接收信道数据并合成语音数据流。
编码器和解码器接口的时序是完全异步的。
AMBE-1000采用A/D-D/A芯片作为语音信号的接口。
输入输出的语音数据流的格式必须是相同的(16bit 线性的,8bit A律,8bit u律),信道接口采用8位或16位的微控制器。
芯片可选择的功能包括回声抵消、VAD(语音激活检测)、电源模式、数据/前向纠错速率的选择等,这些功能由外围管脚或输入到解码器的命令帧来决定。
AMBE数字语音混音板使用说明
南京梧桐微电子
一、 原理框图
二、 功能
该混音板最多支持5路信道的混音处理。
每一路取得的混音编码数据不包含本路的语音,即在A、B、C、D、E共5路数据中,A路的编码数据是来自B、C、D、E共4路的语音编码,其余以此类推。
板上跳线可以设置某一路不参加混音(地址A2A1A0=000路必须参加混音)。
MixV oice是全5路数据混音后的模拟语音输出(暂不提供)。
三、 接口信号
下图为混音板的实物示意图。
J1、J2为电源及信号连接排针,J3、J4为定位排针,J5-J9为跳线,设置相关信道是否参加混音。
从左到右如跨接跳线帽依次设置地址A2A1A0为100、011、010、001的信
道不参加混音。
混音板示意图
相关的信号定义如下:
J1-1、J1-2:电源地;
J1-3、J1-4:正电源5V;
J1-5:全信道混音输出SPK-;
J1-6:全信道混音输出SPK+;SPK+、SPK-之间可以接0.5W 8欧姆的喇叭;
J1-7:保留;
J1-8:全信道混音模拟输出。
J2-1、J2-2(GND):信号地;
J2-3(A2)、J2-4(A1)、J2-5(A0):信道地址信号,用于选择5路之中的一路进行读写操作,有效地址是000、001、010、011、100,其他地址保留。
J2-6(D7)--- J2-13(D0):D[7:0]为并行8位数据线。
同单颗AMBE-1000并行8位数据线。
J2-14(DPE):解码器包空,混音板上5颗AMBE-1000芯片工作是同步的,该信号同单颗AMBE-1000的DPE信号。
J2-15(EPR):编码器包准备好,混音板上5颗AMBE-1000芯片工作是同步的,该信号同单颗AMBE-1000的EPR信号。
J2-16(RD):读选通,该信号由外部输入,混音板上的AMBE-1000芯片在RD的下降沿将数据锁存到数据总线。
J2-17(WR):写选通,该信号由外部输入,混音板上的AMBE-1000芯片在WR的上升沿锁存数据。
J2-18(RESETB):混音板复位信号,低电平有效。
四、 混音板读写方法
混音板的读写操作实际上就是对混音板上AMBE-1000芯片的读写操作。
混音板上有五颗AMBE-1000芯片,用地址A2A1A0来选择
其中一颗进行读写,读写的时序同单颗AMBE-1000的读写时序完全相同。
因此,混音板的操作方法为:先设置地址A2A1A0,然后同读写单颗AMBE-1000芯片一样的进行读写。
混音板上电复位以后,或者通过J2-18(RESETB)信号给混音板复位以后,各信道默认的编码速率为2400BPS。
如实际使用的编码速率不是2400BPS,则要进行码率设置,设置的方法是:先设置好地址A2A1A0,然后同AMBE-1000芯片的码率设置方法一样进行设置。
混音板允许不同的信道采用不同的编码速率。
