泰勒梅 M1 驱动器说明书

FADEDRAWThe 4° Loft Sleeve allows you to adjust the loft, lie and face angle of the M1 driver: • Each of the 12 sleeve movements increases or decreases loft 0.50 - 0.75° • Each of the 12 Sleeve movements increases or decreases lie angle 0.50 - 0.75° • Each of the 12 Sleeve movements increases or decreases face angle 1.0 - 2.0°The M1 460 and 440 Front Track consists of one 15-gram weight to provide a range of draw, neutral and fade ball flights:• Fade – Position the weight towards the toe• Neutral – Position the weight in the center of the track • Draw – Position the weight towards the heel TOUR FIT SYSTEMTUNING MANUALAdjusting the M1 driver is simple by way of a 3 step system created to allow golfers to optimize launch conditions. Follow these steps to ensure you are achieving high launch and low spin to complement your ideal shot shape. The adjustable back weight in the M1 adds the ability to adjust spin, launch and playability to ensure all golfers can maximize their distance.ADJUSTING THE M1Adjusting the M1 family is simple with the TaylorMade torque wrench. Use the wrench to loosen the screw in the center of each weight, then slide the weight to the desired location and lock it in place by tightening the screw until you hear an audible “click” noise from the wrench.In order to adjust the Loft Sleeve, loosen the screw in the heel until the clubhead releases from the shaft. Align the desired loft as marked on the sleeve with the line on the back of the hosel and tighten the screw until you hear an audible “click” noise.1. LOFT, LIE & FACE ANGLE - LOFT SLEEVE2.

Rane Model DC 24 动态控制器说明书

DC 24DYNAMIC CONTROLLERData Sheet-1General DescriptionThe Rane Model DC 24 Dynamic Controller is a two chan-nel Compressor, Limiter, Expander Gate system with very un-usual attributes. The DC 24 oﬀers unprecedented control of its operating parameters as well as a built-in 24 dB/octave Linkwitz-Riley Crossover which gives it very impressive capabilities.Total freedom from control interaction highlight the DC 24 as well as the availability of separate Compressor and Limiter controls. The Compressor oﬀers control over both Ratio and Threshold, while the Limiter allows setting a separate Threshold. In doing this, the DC 24 allows the operator to create a smooth transition between subtle compression over a wide dynamic range and peak-stop limiting at the sound system’s highest allow-able level. If that’s not enough, the DC 24 also oﬀers indepen-dent Expander/Gate Ratio and Threshold controls. This third level of signal manipulation makes the DC 24 a most useful and revolutionary device.Attack and release times are automatic and program depen-dent. This simpliﬁes use of the DC 24, as these subtle controls can confuse most users. History has proven that experienced compressor users rarely miss these controls after using a DC 24.The internal Crossover allows the DC 24 to operate as a two-way speaker dividing network along with all of the dy-namic characteristics of a fully featured Compressor Limiter. In addition to this application, the DC 24 supplies the necessary circuitry to allow the unit to divide a single channel of audio information in two separate frequency ranges and to then re-combine the program material into one Channel. Using the DC 24 in this way eliminates the pumping and breathing associated with compression and limiting when only one Channel is used to cover the entire audio spectrum.Refer to “The DC 24 User’s Guide,” on the Rane website, for an easy-to-understand guide of operation and applications.Features• Ratio & Threshold Controls for Compressor and Gate/Expander • Limiter Threshold Controls• Program Dependent Attack & Release• Linkwitz-Riley Crossover with 24 dB per Octave Slopes • Low-High Crossover Mode (1 In/2 Out)• Bandsplit Combine Mode (1 In/1 Out)• Stereo/Dual Modes (2 In/2 Out)• Side Chain Insert Jacks• Balanced XLR & ¼" TRS Connectors • -10 dBV / +4 dBu Gain Switch• UL/CSA Remote Power Supply (120 VAC)• CE (Low Voltage & EMC) Remote Power Supply (230 VAC)DATA SHEETDC 24DYNAMIC CONTROLLERData Sheet-2Parameter Speciﬁcation Limit Units Conditions/CommentsCompressor..........Threshold Range -50 to +205dB ..........Ratio Range 1:1 to 10:110%Expander / Gate..........Threshold Range -50 to +105dB ..........Ratio Range 1:1 to 20:110%Limiter..........Threshold Range -20 to +202dBCrossover ..........Type Linkwitz-Riley 4th-order 24 dB per octave slopes..........Range 70 Hz to 7 kHz5%41-detent continuously variable pot Inputs: Type Active Balanced / Unbalanced ..........Connectors XLR & + ¼" TRS ..........Impedance20k 1%Ω..........Maximum Level +201dBuOutputs: Type Active Balanced ..........Connectors XLR & + ¼" TRS ..........Impedance1001%ΩEach output ..........Maximum Level +261dBu 2 kΩ or greater +201dBu 600 Ω or greaterOverall Gain Range -12 to +12±1dB Center detent unity gainRFI FiltersYes Passive Bypass SwitchYes LED Thresholds: Overload +221dBu Output or any internal level ..........Signal Present -403dBu Input LevelFrequency Response 20 Hz to 20 kHz +0/-.5dB THD+Noise0.05.01%+4 dBu, 1 kHzIM Distortion (SMPTE)0.1.01%60 Hz / 7 kHz, 4:1, +4 dBuSignal-to-Noise Ratio 1082dB Unity Gain re +20 dBu, 20 kHz BW 922dBUnity Gain re +4 dBu, 20 kHz BW Unit: Agency Listing ..........120 VAC model Class 2 Equipment National Electrical Code UL & CSA Exempt Class 2 equipment ..........230 VAC model CE-EMC EMC directive 89/336/EECCE-SafetyExempt per art. 1, LVD 73/23/EEC Power Supply: Agency Listing Rane model RS 1Class 2 Equipment ..........120 VAC model UL File no.

The gating function shall provide a means for setting the gate threshold as well as the ratio of the function thus providing a means for gentler slopes to oc-cur such as one would expect to ﬁnd in an expander.The compressor shall also provide a means for setting thresh-old and ratio independently. The limiter shall also provide a means for setting its operational threshold, but shall diﬀer from the other two functions in that limit ratio shall be a function of limit level.All attack and release characteristics provided by the dynam-ic controller shall be a function of the current program material, thus providing a high level of transparency to the listener.The dynamic processor shall provide an active crossover circuit for the purpose of using the unit to drive ampliﬁers con-nected to two-way loudspeaker systems as well as for dividing a single channel audio source into two frequency bands for ulti-mate recombination at the outupts of the device. The crossover shall be a fourth-order Linkwitz-Riley type conﬁguration.Passive bypass switches shall be provided to ensure total bypass of the unit’s active circuitry in the event of power failure. The inputs and outputs shall be active balanced/unbalanced designs terminated with XLR & ¼" TRS connectors. The side-chain send and receive connectors shall be ¼" unbalanced types, wired tip=send, ring=return.RFI ﬁlters shall be provided at the processor’s inputs. LEDs shall be provided to indicate the presence of an input signal as well as high level overload conditions.The unit shall be exempt from agency safety requirements and powered from a UL listed / CSA certiﬁed remote power sup-ply (120 VAC), or CE approved (230 VAC) via a rear panel input modular plug.The unit shall be entirely constructed from cold-rolled steel, and mount into a standard EIA relay rack occupying 1 rack space.The unit shall be a Rane Corporation Model DC 24.DC 24DYNAMIC CONTROLLERData Sheet-4All features & speciﬁcations subject to change without notice.DOC 107501Rear PanelAvailable Accessories • SC 1.7 Security Cover©Rane Corporation 10802 47th Ave. W., Mukilteo WA 98275-5098 TEL 425-355-6000 FAX 425-347-7757 WEB Application InformationTraditionally, a product such as the DC 24 has been referred to as a “Compressor / Limiter” because the range of the Ratio control on the Compressor has been wide enough to accommo-date both gentle compression and harder limiting eﬀects. Not, however, simultaneously. One had to make a choice between the two modes of operation. On some models a Gate has been pro-vided which may or may not be part of the Compressor function.In the DC 24, all three functions of each channel are inde-pendent. Gating may occur when low-level signals are present, compression may occur when the level increases, and “peak-stop” limiting is available for high-level signals. This provides a three slope capability which is rather unique in the audio industry.Additionally, the DC 24 can help out a great deal on the low end of the amplitude spectrum by serving as a noise gate simul-taneously. The Compressor may be used to “tighten” vocals and instrumentals while leaving the Limiter function available for use as a safety valve.To accomplish this feat, the DC 24 provides three separate “Side Chains” in each Channel, each having its own set of front panel controls. For the Gate / Expander function, input signal is converted from an audio format to a control signal and ap-plied to the threshold circuit. If the output of the controller is below the speciﬁed threshold, it is passed along to the Gate / Expander Ratio control. The Ratio control allows attenuation of the controller to inhibit the slope of the Expander. After this at-tenuation, the control signal is delivered to the Channel’s control summing ampliﬁer where it will meet similar signals generated by the Compressor control system.The Compressor controller works remarkably similarly to the Gate, the exception being the polarity. While the Gate circuit reduces gain when input level decreases below Threshold, the Compressor decreases gain when input increases above Thresh-old. The Compressor also receives the output of the controller, applies it to its threshold determinator, and passes the signalto the ratio attenuator if threshold conditions are satisﬁed. The output of the Ratio control is applied to the summing ampliﬁer referenced in the gate section.Side Chain inserts have been provided on the rear of the unit to allow the insertion of an equalizer into the control circuits of the Gate and the Compressor. This will allow the user to create a frequency-dependent threshold for the Gate and/or the Compressor. This feature is useful when attempting to control sibilance in vocals.The Limiter operates in an entirely diﬀerent manner than the preceding sections. The control circuit for the Limiter monitors the output of the VCA, not the input of the unit. Anytime the output of the VCA exceeds the Threshold set on the front panel, Limiting begins to take place. The ratio of the Limiter is set automatically and is a function of the excess level the system is attempting to deliver above the preset Threshold. The attack and release time of the Limiter is a function of the speed at which the input signal is attempting to drive the output of the unit above the Threshold level.The Crossover function of the DC 24 is based on Rane’s time-proven 4th-order state-variable Linkwitz-Riley design. This yields a 24 dB per octave slope and an in-phase characteristic. Since the outputs are in phase with each other, they recombine properly when the channel summing mode is selected via the rear panel Separate/Combine switch.In its band-split mode, the DC 24 allows separate processing of low frequencies and high frequencies; a mode which makes its operation all the more transparent. When the Crossover is used in conjunction with a two-way loudspeaker system, adequate driver protection may be ensured while providing a very ﬂexible means of program manipulation.For a better view of the various operational modes, refer to “The DC 24 Users Guide” RaneNote, from the Rane website.。

mems imu 旋转调制

mems imu 旋转调制英文回答：MEMS Inertial Measurement Units (IMUs) and Rotation Modulation.MEMS (Microelectromechanical Systems) IMUs are small, low-power devices that measure linear acceleration and angular velocity. They are used in a variety of applications, including navigation, attitude control, and vibration measurement.Rotation modulation is a technique used in MEMS IMUs to improve the accuracy of angular velocity measurements. In rotation modulation, the IMU is rotated at a known frequency and the angular velocity is measured at different points in the rotation cycle. This allows the IMU to compensate for errors caused by the Coriolis effect and other factors.Rotation modulation is typically implemented using a dither motor. The dither motor rotates the IMU at a known frequency, and the angular velocity is measured using a piezoelectric sensor. The piezoelectric sensor generates a voltage proportional to the angular velocity, and this voltage is used to estimate the angular velocity of the IMU.Rotation modulation can significantly improve the accuracy of angular velocity measurements. In some cases, rotation modulation can improve the accuracy by a factor of 10 or more. This makes rotation modulation an essential technique for applications that require high-precision angular velocity measurements.中文回答：MEMS惯性测量单元（IMU）和旋转调制。
