Not so with Tannoy installation products. Tannoy in-wall speaker systems are monitor quality speaker systems based on the company’s expertise in the manufacture of premium quality cabinet loudspeakers and studio monitors.The iwSA 500 amplifier was created specifically to maximize the inherent performance of your T annoy inwall subwoofer. By carefully matching the amplifier’s capabilities and performance criteria to the inwall subwoofer, Tannoy has enabled installers and end users to carefully tailor the performance to the job at hand.iwSA 50023446756.0 CONNECTIONS6.1 Input Connections 6.2 Connecting the Speaker 6.3 Cable Choice7.0 OPERATION7.1 Operation Precautions8.0 PROTECTION FEATURES8.1 Limiter Function9.0 MAINTENANCE 10.0 TROUBLESHOOTING 11.0 WARRANTY12.0 Technical Specifications iwSA 5008978882.4 User Responsibility 2.4.1 Speaker Damage 2.4.2 Radio Interference4.0 INTRODUCING THE iWSA 5004.1 Unpacking 4.2 Front Panel 4.3 Rear Panel5.0 INSTALLATION5.1 Mounting5.2 Operating Voltage43.0 APPROVALSThis equipment is tested and approved according to the Canadian Standards Association (CSA/C/US) and Federal Communications Commission (FCC).2.4 USER RESPONSIBILITY 2.4.1 Speaker DamageYour amplifier is very powerful and can be potentially dangerous to both, loudspeakers and humans alike. Many loudspeakers can be easily damaged or destroyed by overpowering, especially with the high power available. Always check the speakers’ continuous and peak power capabilities.Even is the amplifier’s front panel attenuators can be used to reduce the gain, it is still possible to reach full output power if the input signal level is high enough.TANNOY iwSA 5002.4.2 Radio InterferenceThis equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference from electrical equipment. This product uses radio frequency energy and if not used or installed in accordance with these operating instructions, may cause interference `in a particular installation.If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment on and off,the user is encouraged to try to correct the interference by one or more of the following measures:• Reorient or relocate the antenna.• Increase the separation between the equipment and receiver.• Connect the equipment into an outlet on a a circuit different from that to which the receiver is connected.• Consult the dealer or an experienced radio/TV technician for help.TANNOY iwSA 500iwSA 5007TANNOY iwSA 5006.3 Cable ChoiceAlways use the best quality of cable available within your budget. High quality audio signals passing from the amplifier to the loudspeaker are unusual in their demands on the cable. Wide dynamic range and frequency bandwidth information has to coexist with the ability to transmit peak currents of at least 10 Amps, without incurring any loss or signal impairment. This explains why the sound quality of the information reproduced by the loudspeakers is so dependant on the physical properties of the cables connecting them to the amplifier.Technically, we recommend two-core cable with cross section area not less than 1.5mm 2 (14 gauge) for cable runs of up to 3 metres. For longer lengths we would suggest that you use cable with a minimum cross sectional area of 2.5mm 2 (12 gauge).Keep the speaker cable leads as short as possible. Do not use shielded leads, such as microphone or guitar cable. Remember that the speaker cable robs the power of the amplifiers in two ways: by increasing the load impedance and by introducing resistive power losses.iwSA 5005.0 INSTALLATION The amplifier is two rack units high (2U) and will fit into a standard EIA 19” rack. Amplifiers should not be stacked directly on top of each other,we recommend a space at least 3” for the top and sides with 5” on the back . When shelf mounted the height of the supplied feet is adequate.5.1 MountingWARNING!A label just above the mains cable connector on the rear of the amplifier indicates the AC mains voltage for which the amplifier is wired. Connect the power cable only to the AC source referred to on the label. The warranty will not cover damage caused by connecting to the wrong type of AC mains.5.2 Operating Voltage6.0 CONNECTIONS From an unbalanced source the hot (+) center conductor connects to the center pin of the RCA connector. The (-) shield connects to the chassis of the RCA connector.From a balanced source the hot (+) conductor connects to the center pin of the RCA connector. The cold (-) and the shield connect to the chassis of the RCA connector.6.1 Input ConnectionsSpeaker connections are made via 4 gold plated binding posts. When connecting 1 subwoofer to the amplifier the (+) wire connects to the RED (+) binding post of output #1. The (-) wire connects to the BLACK (-) binding post of output #2.When connecting 2 Tannoy subwoofers one will connect to output #1. Negative (-) wire to BLACK binding post and positive (+) wire to RED binding post. The second will connect to output #2. Negative (-) wire to BLACK binding post and positive (+) wire to RED binding post.Never connect either output terminal to ground or to some other output or input terminal. Pay attention to speaker polarity; loudspeakers connected out of polarity degrade sound quality, and may be damaged as a consequence.6.2 Connecting The Speaker7.0 OPERATION• Make sure that the power switch is set to “off” before connecting any input or output, or operating the switch on the rear panel.• Make sure that the AC mains voltage is correct, and the same as the one printed on the rear panel of the amplifier.• Make sure that the switch on the rear panel for limiter function is in the correct position.7.1 Operation PrecautionsTANNOY iwSA 5008.0 PROTECTION FEATURES8.1 Limiter FunctionThe limiter function is included to prevent dangerous clipped signals reaching the speaker and damaging it. If an amplifier is severely overdriven, its output waveform is clipped (its peaks are squared off) - reducing the crest factor. In extreme cases the waveform can approach that of a square wave. An amplifier is normally capable of producing far more power under these conditions than its normal undistorted rated output power.The Tannoy iwSA 500 Amplifier has two modes of thermal protection and an auto shut down when an internal fault is detected.It is important to have the limiter function switch in the correct position for the number of subs connected, as it sets the amount of output power before limiting occurs.9.0 MAINTENANCEUnder normal use the amplifier should provide years of trouble-free service, with no maintenance required.10.0 TROUBLESHOOTINGThese are typical things to check if you think your amplifier is faulty:FAULT: No power indicator light• Check for proper voltage at receptacle.• Make sure power cord is properly seated in connector on the rear of the amplifier.• Check power switch on back of amplifier.• Check fuse located in holder/drawer below power input connector on back of amp.FAULT: No output• If the power indicator light is on, verify that there is a usable signal on the input.• Check position of level control knob on the front of the amplifier.• Check speaker cable connections on the output binding posts for bad connections.• Check speaker cables for possible short circuits.FAULT: The amplifier does not respond even after having checked the above items.In the unlikely event of a non-user rectifiable fault return the amplifier to your supplier, or an approved service center.Tannoy cannot be held responsible for damage or injury as a result of the top or bottom cover being removed.11.0 WARRANTYNo maintenance of Tannoy products is necessary.All of our products have been produced and tested with care and precision to give first-class service.All passive components are guaranteed for a period of five years from the date of purchase from an authorized Tannoy dealer subject to the absence of evidence of misuse, overload or accidental damage.All active and electronic components are guaranteed for a period of one year from the date of purchase from an authorized Tannoy dealer subject to the absence of, or evidence of, misuse, overload or accidental damage.If at any time during this warranty period the equipment proves to be defective for any reason other than accident, misuse, neglect, unauthorized modification or fair wear and tear, we will repair any such manufacturing defect or, at our option, replace it without charge for labour, parts or return carriage.If you suspect a problem with a Tannoy product then, in the first instance, discuss it with your Tannoy dealer.

2015年P型音频分析仪数字多功能多元器测量仪数据手册说明书

The 2015-P Audio Analyzing Digital Multimeter and the 2015 Total Harmonic Distortion Multimeter combine audio band quality measurements and analysis with a full-function 6½-digit DMM. Test engineers can make a broad range of voltage, resistance, current, frequency, and distortion measurements, all with the samecompact, half-rack measurement instrument. The 2015-P offers additional processing capacity for frequency spectrum analysis.Key Features•THD, THD+Noise, and SINAD measurements •20 Hz–20 kHz sine wave generator •Fast frequency sweeps•2015-P identifies peak spectral components •Sine wave generator maximum amplitude: 4 Vrms single-ended or 8 Vrms differential output •Individual harmonic magnitude measurements • 5 standard audio shaping filters •13 DMM functions (6½ digits)•GPIB and RS-232 interfaces2015 6½-Digit THD Multimeter2015-P 6½-Digit Audio Analyzing MultimeterDatasheetFrequency Domain Distortion AnalysisFor applications such as assessing non-linear distortion in components, devices, and systems, DSP-based processing allows the 2015 and 2015-P to providefrequency domain analysis in conventional time domaininstrum ents. They can measure Total Harmonic Distortion (THD) over the complete 20 Hz to 20 kHz audio band. They also measure over a wide input range (up to750 Vrms) and have low residual distortion (–87 dB). The THD reading can be expressed either in decibels or as a percentage.In addition to THD, the 2015 and 2015-P can com p ute THD+Noise and Signal-to-Noise plus Distortion (SINAD). For analyses in which the individual harmonics are the criteria of greatest interest, the instruments can report any of the (up to 64) harmonic magnitudes that can be included in the distortion measurements. The user can program the actual number of harmonics to be included in a computation, so accuracy, speed, and complexity can be optimized for a specific application. (See Figure 1.)Optimized for Production TestingThe 2015 and 2015-P can perform fast frequency sweeps for characterizing audio-band circuitry in production test systems. For example, the instruments can execute a single sweep of 30 frequencies and transmit both rms voltage readings and THD readings to a computer in only 1.1 seconds. With that data, a complete frequency response analysis and a harmonic distortion vs. frequency analysis can be performed in a very short time. Thus high speed testing of the audio performance of a high volume device such as a cellular telephone can be performed without reducing the number of tests or reducing themeasurements in each test. With these instruments, which are optimized for production testing, test engineers can lower test times, in comparison to test speeds achievable with general purpose audio analyzers, without sacrificingproduction test quality.Datasheet2Figures 2, 3, and 4 demonstrate how the 2015 and 2015-P can provide both time domain and frequency domain measurements in a single test protocol. Figure 2 shows a s ample test system schematic with a telecommunication device in a loop back mode test. The Audio Analyzing DMM’s source provides a stimulusf requency sweep, and the Audio Analyzing DMM measures the response from the microphone circuit. Figure 3 shows the resulting frequency domain analysis of the THD and the first three harmonics as a function of frequency. Figure 4 shows the time domain analysis of micro p hone circuit output voltage as a function of frequency.Figure 2. Total Harmonic Distortion Analysis and Frequency Response of a Portable Wireless Telecommunication DeviceFigure 1. Frequency Spectrum of 1kHz Square Wave. Figure 1 shows a plot of a square wave’s harmonics (frequency components) computed and transmitted to a personal computer by the 2015. A square wave’s spectral content consists of only odd harmonics whose magnitudes are (1/harmonic number × the magni t ude of the fundamental). For example, the magnitude of the third harmonic is 1⁄3 the magnitude of the fundamental.Figure 3. THD and 2nd, 3rd, and 4th Harmonics as a Function of FrequencyFigure 4. Frequency Response 32015 6½-Digit THD Multimeter2015-P 6½-Digit Audio Analyzing MultimeterDual Output SourceThe 2015 and 2015-P include an internal audio band sine wave source for generating stimulus signals. A second output, the inverse of the first output, is also available, simplifying the testing of differential input circuits for common mode or noise cancellation performance. The 2015 and 2015-P have a 4 Vrms single-ended output and 8 Vrms differential source output.Wide Selection of Audio FiltersFive industry-standard bandpass filters are provided for shaping the input signal for audio and tele c om m u n ica t ion applications. Available filters include the CCITT weighting filter, CCIR filter, C-message filter, CCIR/ARM filter, and “A” weighting filter (see Figures 5a–5e ). The 2015 and 2015-P provide programmable, high cutoff (low pass) and low cutoff (high pass) filters. Furthermore, the two filters can be implemented together to form a bandpass filter. The programmable filters can be used to fi lter out noise generated by electromechanical machinery on the production floor or to simulate other types of system transmission charac t eristics.Figure 5a.Figure 5b.Figure 5c.Figure 5d.Figure 5e.Datasheet4Broad Measurement FlexibilityIn addition to their THD, THD+Noise, SINAD, and individual har m onic measure m ent capabilities, the instruments provide a compre h en-sive set of DMM functions, including DCV, ACV, DCI, ACI, 2WΩ, 4WΩ, temperature, frequency, period, dB, dBm, and continuity measure m ents, as well as diode testing. This multi-functional design minimizes added equipment costs when config u ring test setups.Wide Band or Narrow Band Noise MeasurementsThe 2015 and 2015-P are capable of measuring both wide band noise and narrow band noise. Alternatively, these instruments’ DSP (digitalsignal processing) capabilities allow users to make frequency domain measurements of RMS voltage noise over the 20 Hz–20 kHz frequency audio band or a narrow portion of the band. Furthermore, noisemeasurements can be extracted in the presence of a stimulus signal for fast signal-to-noise c omputations.Spectrum AnalysisThe 2015-P has internal computationalcapabilities that allow it to characterize an acquired signal spectrum. This instrument can identify and report the frequency and amplitude of the highest value in a complete spectrum or within a specified frequency band. It can also identify additional peaks in descending order of magnitude (see Figure 6). The 2015-P’s on-board capabilities make it simple to obtain a thorough analysis of a frequency spectrum more quickly and with little or no need for external analysis software.Figure 7. Rear panel of both modelsFigure 6. The 2015-P directly identifies peak values of the f requency spectrum.Typical Applications• Wireless communication device audio quality testing • Component linearity testing• Lighting and ballast THD limit conformance testing • Telephone and automotive speaker testing2015 6½-Digit THD Multimeter2015-P 6½-Digit Audio Analyzing Multimeter SpecificationsDistortion CharacteristicsVoltage Range 100 mV, 1 V, 10 V, 100 V, 750 V (user selectable).Input Impedance 1 MΩ paralleled by <100 pF.Display Range 0–100% or 0–100.00 dB.Resolution 0.0001% or 0.00001 dB.Fundamental Frequency Range 20 Hz–20 kHz.Harmonic Frequency Range 40 Hz–50 kHz.Frequency Resolution 0.008 Hz.Frequency Accuracy ±0.01% of reading.Frequency Temperature Coefficient≤100 ppm over operating temperature range.Distortion Measurement Audio FiltersNone C-MessageCCITT Weighting CCIR/ARMCCIR “A” WeightingNumber of Harmonics Included in THD Calculation2 to 64 (user selectable).HI and LO Cutoff Filters (bus settable)20 Hz–50 kHz.

如何使用莱斯康LEXICON MPX500效果器

如何使用莱斯康LEXICON MPX500效果器一、首先设定声频信号电平输入1、首先将所有的效果旁路，对于系统参数，旁路方式（BYPASS MODE）必须设成通过干的声频信号。

为此应该：按下SYSTEM，进入系统方式。

转动EDIT旋钮1.显示BYPASS MODE。

转动EDIT旋钮3.选择DRY（干信号）。

在按SYSTEM，推出系统方式。

按BYPASS（旁路）。

2、对于很大电平的节目素材，先从极低的输入电平开始，然后漫漫提高输入电平。

3、当听出有可闻失真时，或当显示中的削波指示灯持续点亮时，将输入电平降低，直至削波表只在出现最高峰值时点亮为止。

输入电平调整控制可使MPX500由电平范围在+20DB至+8DB输入信号来驱动，最低的设定（逆时针旋到底）对于+4DB（平衡式）输入最佳的，最高设定（顺时针旋到底）对于-10DB（非平衡）输入是最佳的。

输出：1、按SYSTEM，进入到系统方式。

将显示出OUTPUT LEVEL（输入电平）（第一个系统参数）。

2、转动EDIT旋钮3，设定OUTPUT LEVEL。

对于+4DB输入设备，0DB 应为增益单位。

对于-10DB输入设备，-12DB应为增益单位。

3、在按SYSTEM，退出系统方式。

二、选择和安装程序MPX500的程序被组织到24个工厂记忆库和一个用户库中。

当开启电源时，单元将显示和装入所使用的最近一个程序。

要想显示MPX500中的任何程序，只需要简单转动前面板的PROGRAM（程序）旋钮，旋钮会快速选择当前库中的其它程序，然后在继续检索其它剩下的程序。

要想在库间进行切换，则要在转动的同时，按下PROGRAM旋钮。

如果所选的程序不是当前装入的程序，则LOAD（安装）LED点亮。

在4秒之后，显示将转回到显示当前的程序，但是L OAD LED将还会亮着，以表示上一个所选程序已提示用来安装，被提示的程序的号码将出现在显示屏中当前库的名字的左边，并反白显示，要想安装提示的程序，则按下LOAD。
