To purchase these accessories, contact your local Bose dealer or visit w CAUTION: Do not use any other hardware to mount the speakers.Setting UpRLAcoustimass 3 systemAcoustimass 5 systemEnglish - 7Setting UpConnecting the Acoustimass ® module to your receiver or amplifierThe speaker wires without plugs connect the Acoustimass module to your receiver or amplifier. Your speaker system works withr eceivers or amplifiers rated from 10 to 200 watts per channel with 4 to 8 ohm impedance. Refer to your receiver or amplifier owner’s guide.CAUTION: Incorrect wiring results in little or no bass output and could damage the system.1. Connect the speaker wires to the INPUTS FROM AMP OR RECEIVER terminals on the Acoustimass module’s rear panel:A. Connect the marked wire to the positive (+) terminal of the L (left) pair of input terminals.B. Connect the unmarked wire to the negative (–) terminal of the L (left) pair of input terminals.C. Repeat steps A and B with the other speaker wire for the R (right) pair of input terminals.–R +–L +OUTPUTSTO CUBE SPEAKERS–R +–L +INPUTSFROM AMP OR RECEIVER2. Connect the other ends of the cables to the speaker terminals of your amplifier or receiver.A. Connect the marked wire connected to the L (left) pair of input terminals on the module to the LEFT positive (+) terminal on youramplifier or receiver. B. Connect the unmarked wire connected to the L (left) pair of input terminals on the module to the LEFT negative (–) terminal onyour amplifier or receiver.C. Repeat steps A and B with the wire connected to the R (right) pair of input terminals on your Acoustimass module and theRIGHT pair of input terminals on your amplifier or receiver.–R+–L +OUTPUTSTO CUBE SPEAKERS–R+–L +INPUTSFROM AMP OR RECEIVERBefore plugging in your receiver or amplifier:• Ensure no strands of wire from any terminal are brushing against any other terminal. Such “bridged” wires create short circuits which can damage your receiver or amplifier.• Check all connections to avoid damaging your speakers. Make sure the speakers are connected to the module and not directly to the amplifier or receiver.Checking the systemWith your amplifier and Acoustimass ® module powered, your system should respond accordingly:• With the balance control on your amplifier turned to the left, sound comes from the Acoustimass module and left speaker only.• With the balance control turned to the right, sound comes from the Acoustimass module and right speaker only.• With the balance control in the center position, music with bass should be the same or louder with the control in the center than to the left or right.If your system does not respond as described, check all the wires for proper positive to positive and negative to negative connections. If your system still doesn’t respond properly, see “Troubleshooting” on page 8.Understanding automatic system protectionWhen played at high volume, your Acoustimass systems’ automatic protection circuit activates to prevent damage to the system from electrical stress or overload. When this happens, you may notice a slight decrease in volume. This indicates that the power input may have exceeded safe levels. Setting the volume at or above this level for sustained periods is not r ecommended.Care and MaintenanceTroubleshootingProblem What to doDistorted or no sound• Disconnect the amplifier or receiver from the system, and reconnect the Acoustimass® module to another amplifieror receiver that is working properly. If the system now works, the problem is in your amplifier or receiver.• Power off the amplifier or receiver and check all the connections between the speakers, the module, and amplifieror receiver.• Refer to your amplifier or receiver’s owner’s guide for more troubleshooting information.• See “Checking your receiver or amplifier’s speaker channels”.Checking your receiver or amplifier’s speaker channelsIf one of the speakers does not play or sounds distorted, your amplifier or receiver’s speaker channel may be defective.1. Disconnect both speaker cables from the amplifier or receiver.2. Reconnect the cable from the Acoustimass® module’s L INPUTS to the amplifier or receiver’s right speaker terminals.3. Disconnect both speaker cables from the amplifier or receiver. Reconnect the cable from the Acoustimass® module’s L INPUTS tothe amplifier or receiver’s right speaker terminals.4. Set the amplifier or receiver’s balance control all the way to the right and power it on. If the left speaker now plays properly, youramplifier or receiver’s left speaker channel may be defective.5. Repeat to check your right speaker, reconnecting the cable from the module’s R INPUTS to the amplifier or receiver’s left speakerterminals.CAUTION: DO NOT connect the other speaker to the potentially defective channel. If the channel is defective, it could d amage your Acoustimass system.Cleaning• Clean the surface of the system with a soft, dry cloth.• Do not use any sprays near the system. Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia or abrasives.• Do not allow liquids to spill into any openings.• You can vacuum the speaker grilles.

OPA846中文资料

ELECTROSTATIC DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
A new external compensation technique can be used to give a very flat frequency response below the minimum stable gain for the OPA846, further improving its already exceptional distortion performance. Using this compensation makes the OPA846 one of the premier 12- to 16-bit Analog-to-Digital (A/D) converter input drivers. The supply current for the OPA846 is precisely trimmed to 12.6mA at +25°C. This, along with carefully defined supply current tempco in the input and output stages, combine to provide exceptional performance over the full specified temperature range.

It is quite simple to obtain this function using a microprocessor (Fig. 1 and 2).At first St-by signal (from µP) goes high and the voltage across the St-by terminal (Pin 7) starts to increase ex-ponentially. The external RC network is intended to turn-on slowly the biasing circuits of the amplifier, this to avoid "POP" and "CLICK" on the outputs.When this voltage reaches the St-by threshold level, the amplifier is switched-on and the external capacitors in series to the input terminals (C3, C5) start to charge.It's necessary to mantain the mute signal low until the capacitors are fully charged, this to avoid that the device goes in play mode causing a loud "Pop Noise" on the speakers.A delay of 100-200ms between St-by and mute signals is suitable for a proper operation.Figure 1.

INSTRUCTION MANUALFor Model 7290A Microtron® Variable Capacitance AccelerometerIM7290A, Revision AThe Model 7290A Microtron® is a rugged, variable capacitance accelerometer with integral electronics for voltage regulation, filtering and signal amplification. As is the practice with all instrumentation, certain precautions should be followed with check-out, mounting and recalibration.Materials RequiredAll the materials used in the mounting of the Model 7290A Microtron accelerometer are supplied with the unitin the shipping container. These materials, as shown in Figure 1, include:(1)Allen wrench for 4-40 screws- Endevco P/N EHM464(2)4-40 x 7/16 inch Socket Head Cap Screws- Endevco P/N EH702(2)Size 4, Flat Washers- Endevco P/N EHW265For biaxial or triaxial acceleration measurements, the user should consider the Model 7990 Triaxial Mounting Block which is available as an optional accessory.Check-outBefore installation of the accelerometer, it should be checked to insure proper operation. A simple Zero Measurand Output and 2 g Turnover test can be conducted with minimal test equipment. Place the unit on its side so that the accelerometer mounting surface is perpendicular to the table top. Apply the specified excitation voltage to the accelerometer (see data sheet for proper wiring hook-up) and measure the output with a dc millivolt meter. Allow the unit to warm-up for two minutes. The accelerometer should have a Zero Measurand Output (ZMO) within the specified limits in the data sheet.To perform the 2 g Turnover Test, the Model 7290A Microtron is oriented with its mounting surface on the table top (sensitive axis is vertical) and the output is measured with the dc millivolt meter. The unit is then turned over 180°, resulting in a change of 2 g, and the output is again noted. The sensitivity is computed by dividing the change in output by 2 g. The sensitivity in mV/g should be within the specified limits in the data sheet.If this initial check does not give a proper reading, indicating a possible malfunction, and the reason for the erroneous reading cannot be found, contact Endevco at +1 (866) 363-3826.IM7290A, Page 1MountingWhen mounting the Model 7290A Microtron accelerometer, it is best to utilize the proper techniques and tools listed to ensure optimum performance. For triaxial acceleration measurements, the Model 7990 Triaxial Mounting Block is available - see paragraph 7 below.1.The mounting surface should be clean and free of burrs. Two #4-40 tapped holes, 0.2 inch minimum depth should be spaced 0.825 inches (20.96 mm) apart. A 32 micro inch rms surface finish with flatness of 0.0001 inches is recommended for the area that will contact the accelerometer. The sensitive axis of the unit is perpendicular to the mounting surface, so the angular alignment of the two mounting holes is not critical.2.If possible, do not cement the unit to the mounting structure. Use the supplied mounting washers and screws, as shown in Figure 1. Metric size screw M3 may also be used. Note: Adhesive mounting may be used, if necessary. Adhesion of epoxies to the hard anodized case is excellent, but thermal mismatch to the mounting surface can degrade the joint. A compliant adhesive, such as Dow Corning 3145 RTV, is recommended. Use care to maintain flatness of the unit during curing to reduce cross talk errors.FIGURE 1- Installation of Model 7290A Microtron Accelerometer3.Remove the unit from the shipping container. Place the unit on the mounting surface and align the mounting holes.4.Slide the washers over the screws. Using the supplied wrench or a torque wrench, tighten the screws to 6 lbf-in (0.7 Nm). This is roughly equivalent to finger tight with the supplied wrench.5.As practical, tie down the cable within 2 to 3 inches (4 to 6 cm) of the unit. Whipping of the cable during vibration and shock will strain the cable unnecessarily at the unit. The cable jacket is silicone, so care should be taken to avoid cutting or tearing the jacket. The cable is rated for 300°F (150°C) continuous service.6.Connect the unit to the signal conditioner using the following lead designation:Red- Excitation +Green- Output +White- Output -Black-Ground7.For triaxial acceleration measurements, the Model 7990 Mounting Block is attached to the mounting surface with three (3) 6-32 x 1 inch socket head cap screws as shown in Figure 2, with subsequent attachment of the (3) Model 7290A Microtron Accelerometers per steps 2 through 6 above.FIGURE 2- Installation of (3) Model 7290A Microtron Accelerometers onto Model 7990 Triaxial BlockElectrical Precautions1.Excitation- The Model 7290A Microtron has an internal voltage regulator, so excitation from +9.5 to +18 Vdc is adequate. A low noise power supply is recommended and care should be taken to minimize pickup on the cabling to the accelerometer. The maximum current drain over the entire operating range is 15 mA.2.Signal Leads- The green and white signal leads are differential. The green lead has a varying output, while the white lead is fixed at a reference voltage of approximately +3.6 Vdc. However , using the Model 7290A Microtron in a single- ended mode is not recommended since the internal temperature compensation also corrects for thermal change in the reference voltage. Although the output is high level, at ±2 Vdc, the usual precautions of using twisted pair, shielded instrumentation cable should be taken to avoid noise pickup on the signal leads.3.Grounding- The case of the Model 7290A Microtron is not attached to circuit ground, and the cable shield is not attached to the case or to circuit ground. The recommended grounding scheme is to ground the cable shield at the power supply ground and to no other point to avoid ground loops.4.Signal Conditioning- The Model 7290A Microtron has a high level differential output of ±2 Vdc, biased at 3.6 Volts. The 0 g reading, or Zero Measurand Output (ZMO), is 0 volts ± 50 mV. When the accelerometer is subjected to acceleration of 1.75 times range, the output of the unit will electrically clip, with a recovery time of < 10 µseconds.5.Loading Effects- The Model 7290A Microtron accelerometer performs within specification limits while loaded with 10,000 ohm minimum resistance, and/or 0.1 µfarad maximum capacitance.Shunt CheckA Shunt Check is performed in applications where the Model 7290A Microtron accelerometer is already mounted on a test structure and cannot be dynamically checked with a 2 g Turnover test. Full details of the Shunt Check procedure is contained in Endevco Tech Data A542.However, in brief, the shunt check is performed by connecting a precision fixed resistor of known value to the positive output (green lead) of the accelerometer. The other end of the shunt resistor is connected to an excitation voltage source to promote output shifts simulating positive direction accelerations, or to circuit ground for shifts in the negative direction.The nominal output voltage shift (E sh) based on the fraction of full scale reading desired is:E sh= SENS * FS * nwhere:E sh = output voltage shift, VdcSENS = sensitivity, volts/gFS = ± full scale acceleration, gn = fraction of full scale readingKnowing the desired output voltage shift, (E sh) the value of the external shunt resistor (R sh) is:R sh = (V sh - V ent - V wh - E sh) x R out____________________________________E shOr conversely, given the value of the external shunt resistor (R sh), the expected output voltage shift, (E sh ) is:E sh = (V sh - V out - V wh) * R out_______________________R sh + R outwhere:R sh = selected external shunt resistorV sh= voltage applied to shunt resistor (for + acceleration shifts, connect to excitation, V sh =+9.5 to 18.0 Vdc and for negative acceleration shifts, connect to circuit ground, V sh = 0 Vdc)V out = output signal measurement unshunted, Vdc (positive output signal (green) withrespect to negative output signal (white))V wh = negative output signal (white) with respect to ground, V wh= 3.5 ±0.1 VdcR out = output impedance, ohms (R out = 470 ± 24 ohms, ±100 ppm/°C)E sh = output voltage shift, VdcThermal errors have no significant effect on accuracy as long as the unshunted and shunted measurements are taken at the same temperature.RecalibrationSensitivity and Zero Measurand Output calibration should be performed at 6 to 12 month intervals, depending on usage. Ordinarily, recalibration need be performed only at 12 month intervals if it is known that the accelerometer has not been used beyond its rated specifications. If the unit is used under severe environments, it may be desirable to use shorter calibration intervals.Contact Endevco for local calibration facility information or return the unit to Endevco for recalibration. Endevco maintains an accelerometer recalibration service with NIST traceability in the United States. Endevco European Regional offices maintain accelerometer recalibration services with traceability to national standards.Dirty units may be wiped clean using a damp cloth and a solvent such as acetone.QuestionsIf you have any questions regarding the use of this or any Endevco accelerometer, please contact Endevco at +1 (866) 363-3826 in North America, or your local sales representative.。
