equipment operates best in a clean,dry,well-ventilated environment free of vibra-tion and electromagnetic fields.The following are some guidelines to achieve optimal per-formance.Avoid placing the mixer and cables near heat sources.Be particularly aware of other audioequipment,such as amplifiers,which can produce a great deal of heat when operating.T o minimize hum in the system,avoid placing the mixer and cables near radio frequencydevices and other electromagnetic field sources such as:•Fluorescent lights•Electrical motors•SCR dimmers•AC power lines,etc.Note:Always use 2-conductor shielded cable to reduce EMI or RF interference to theLine/MIC inputs.Keep the mixer and other equipment clean and free of dust by wiping occasionally with a soft,damp cloth.Protect the mixer from electrical damage by disconnecting it from the power source when-ever it will be unused for a week or longer.The Bogen mixer is easy to install and adjust.The only tools needed are:1.Slotted screwdriver2.Phillips-head screwdriverT roubleshooting Gain StructureIf the procedure followed to this point does not give satisfactory results,follow theappropriate adjustment sequence below:If channel clipping occursIf the signal is clipping or producing audible distortion,the gain is too high.Reduce the InputGain/T rim Control (rear panel) by turning it counterclockwise until clipping does not occur.Also make sure that the new setting of the gain control offers a usable control range betweenthe 9 o’clock and 2 o’clock positions on the front panel volume control knob.If channel volume is too lowIf a channel must be set above the 2 o’clock position to provide adequate volume,the inputgain setting is too low.T urn the volume control knob to the 1o’clock position and increasethe input gain by turning the input gain/trim control clockwise until clipping occurs,or VUmeter is over 0 VU.Then adjust the gain to a setting just below the clipping level.If channel volume is too highIf a channel is not clipping but must be set below the 9 o’clock position to achieve the prop-er volume level,the input gain control setting is too high.Reduce the Input Gain/T rim Controlby turning it counterclockwise.Set the volume control knob to the 9 o’clock position andcontinue to adjust the gain control until the desired volume level is achieved.Range for optimal volume control operationsettings (indicator positions).Jumper OptionsChanging Jumper SettingsT o change a jumper setting,remove the ten screws secured to the top of the mixer.Afterremoving the top of the mixer,locate the jumper to be changed by referring to the drawingon page 18.Jumpers are included from the factory in positions:J2,J17,J18,J21,and J22.Warning:Disconnect AC Power before opening case.Bar Graph OptionsThe mixer’s meter can be configured to meter the output of either the main or auxiliary bus.In addition,the bar graph can be configured to register either the peak or average level of theaudio signal.J22-J23The LED Bar Graph Output Meter can be set to register either the main or auxiliary busoutput audio signal.The choices are:J22 installed:The Bar Graph meters the main bus output.This is the factory default.J23 installed:The Bar Graph meters the auxiliary bus output.Note:The meter will operate only when a jumper is in one of these two positions.J20-J21The LED Bar Graph Output Meter can be set to register either the peak or average levelof the output audio signal.The choices are:J20 installed:The Bar Graph meter registers the peak level of the audio output.J21installed:The Bar Graph registers the average level of the audio output.This is thefactory default.Note:The meter will operate only when a jumper is in one of these two positions.Bus Routing OptionsAUX In Jumpers:J17 and J18.These jumpers determine the destination of the AuxiliaryInput.The choices are:J17 installed:Auxiliary Input is routed to Main Output.J18 installed:Auxiliary Input is routed to Auxiliary Output.J17 and J18 both installed:Auxiliary Input is routed to both Main and AUX outputs.This is thefactory default setting.AUX Source Jumpers:J1and J2.These jumpers determine which of two gain controls areused to control the level of the AUX output.The choices are:J1installed:AUX output gain is controlled by the internal pot,“AUX Pregain Pot” RP23 (seepage 18 for location).The front panel AUX output volume knob continues to independentlycontrol the gain of the headphone amplifier jack on the front panel.This setting is typicallyused in a linking situation where the output from a mixer must remain fixed,since J1makesthe output of that mixer tamper-proof (from the front panel).With J1installed,the front panelAUX volume knob controls only the headphone level.J2installed:AUX output gain is controlled by AUX volume knob on front panel.The 1/4-inchHeadphone amp is also controlled by the AUX volume knob,but not independently of theAUX output.Note:Never install jumpers in both positions J1and J2.If both J1and J2 jumpers are installed,then gain is defeated.Simple linking or “daisy-chaining” allows the expansion of mixer inputs in multiples of 8 inputs by chaining together multiple mixers with auxiliary buses.T o preserve certain mixer features, this must be done in the way shown below.Follow these steps (see page 18 for jumper loca-tions):1.For each mixer,remove the jumper from J2 and place it on J1.This causes the Auxiliary Out level to be set by an internal pot,fixing the linked gain structure.The external pot only controls the headphone out level.2.In the last mixer in the chain,remove the jumper from J18.Leave the jumper in place on J17.This routes the AUX In to the Main output,preserving the Compressor/Limiter feature.3.All other mixers in the chain should have jumper J18 in place,and J17 removed.4.Connect each mixer’s AUX Out terminals with the AUX In terminals of the next mixer in the chain.5.T ake the summed daisy-chain output from the Main Out terminals of the last mixer in the daisy-chain.This must be the mixer with J17 in place (from step 2).6.All mixers except the last mixer in the chain (#1in the drawing below) must have all its front panel M-A switches in the A position,to route its inputs to the auxiliary bus.The posi-tion of jumpers J17 and J18 in the first mixer (#4 in the drawing below) do not matter,and can be left undisturbed.Y ou should now have a daisy-chain configured as shown in the drawing below.Note that the position of J17 and J18 are shown within the drawing of each mixer in the chain (except mixer #4 in which the jumper position is immaterial).Destination 1receives inputs from mixer 2 with the M-A switch set to auxiliary,and from mixer 1with the M-A switch set to main.Destination 2 receives inputs from mixer 2 with the M-A switch set to main,and from mixer 1with the M-A switch set to auxiliary.Auxiliary CircuitsBar Graph-18,-12,-6,-3,0,+3,+6,+12 VU(0 VU = +4

C A M教材前半部分Company Document number：WUUT-WUUY-WBBGB-BWYTT-1982GT软件介绍M a s t e r C AM8软件是美国C NC .所研制开发的C A D/C AM系统，是最经济有效率的全方位的软件系统。

包括美国在内的各工业大国皆一致采用本系统，作为设计、加工制造的标准。

M as t e r C A M8为全球P C级C AM，全球销售量第一名，是工业界及学校广泛采用的C AD/C AM系统，以美国和加拿大教育单位来说，共计有2500多所高中、专科大学院校使用此来作为机械制造及NC程式的制作，在中国大陆及台湾其业界及教育单位亦有领先之地位。

M a s t e r C AM8分为四个系统:三维设计系统,铣床3D加工系统,车床\铣床复合系统,线切割\激光加工系统,由于本书作为模具专业C AM教学的特点,我们只介绍与模具设计密切相关的三维设计系统和铣床3D加工系统.一、三维设计系统:(CAD部分)1、完整的曲线功能：可设计、编辑复杂的二维、三维空间曲线。

还能生成方程曲线。

尺寸标注、注释等也很方便。

2、强大的曲面功能：采用N UR B S、P A R AM ETR IC S等数学模型，有十多种生成曲面方法。

还具有曲面修剪、曲面间等（变）半径倒圆角、倒角、曲面偏置、延伸等编辑功能。

3、崭新的实体功能：以P AR AS O LID为核心，倒圆角、抽壳、布尔运算、延伸、修剪等功能都很强。

4、可靠的数据交换功能，可转换的格式包括：IG E S、S A T（AC IS S O LID S）、D X F、C AD L、V D A、S T L、DW G、AS C II。

并可读取P a r as ol i d、HP G L、C A T IA、P R O/E、S T EP等格式的数据文件。

二、铣床3D加工系统.（CAM部分）1、完整三维设计系统。

2、完整的铣床2D、加工系统。
