Read and follow all of Whelen’s written instructions when installing or using this device. Emergency vehicles are often operated under high speed stressful conditions which must be accounted for when installing all emergency warning devices. Controls should be placed within convenient reach of the operator so that they can operate the system without taking their eyes off the roadway. Emergency warning devices can require high electrical voltages and/or currents. Properly protect and use caution around live electrical connections.Grounding or shorting of electrical connections can cause high current arcing, which can cause personal injury and/or vehicle damage, including fire. Many electronic devices used in emergency vehicles can create or be affected by electromagnetic interference. Therefore, after installation of any electronic device it is necessary to test all electronic equipment simultaneously to insure that they operate free of interference from other components within the vehicle. Never power emergency warning equipment from the same circuit or share the same grounding circuit with radio communication equipment. All devices should be mounted in accordance with the manufacturer’s instructions and securely fastened to vehicle elements of sufficient strength to withstand the forces applied to the device. Driver and/or passenger air bags (SRS) will affect the way equipment should be mounted. This device should be mounted by permanent installation and within the zones specified by the vehicle manufacturer, if any. Any device mounted in the deployment area of an air bag will damage or reduce the effectiveness of the air bag and may damage or dislodge the device. Installer must be sure that this device, its mounting hardware and electrical supply wiring does not interfere with the air bag or the SRS wiring or sensors. Mounting the unit inside the vehicle by a method other than permanent installation is not recommended as unit may become dislodged during swerving; sudden braking or collision. Failure to follow instructions can result in personal injury. Whelen assumes no liability for any loss resulting from the use of this warning device. PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER USE OF EMERGENCY WARNING DEVICES IS ESSENTIAL TO INSURE THE SAFETY OF EMERGENCY PERSONNEL AND THE PUBLIC.Warnings to UsersWhelen’s emergency vehicle warning devices are intended to alert other operators and pedestrians to the presence and operation of emergency vehicles and personnel. However, the use of this or any other Whelen emergency warning device does not guarantee that you will have the right-of-way or that other drivers and pedestrians will properly heed an emergency warning signal. Never assume you have the right-of-way. It is your responsibility to proceed safely before entering an intersection, driving against traffic, responding at a high rate of speed, or walking on or around traffic lanes. Emergency vehicle warning devices should be tested on a daily basis to ensure that they operate properly. When in actual use, the operator must ensure that both visual and audible warnings are not blocked by vehicle components (i.e.: open trunks or compartment doors), people, vehicles, or other obstructions. It is the user’s responsibility to understand and obey all laws regarding emergency warning devices. The user should be familiar with all applicable laws and regulations prior to the use of any emergency vehicle warning device. Whelen’s audible warning devices are designed to project sound in a forward direction away from the vehicle occupants. However, because sustained periodic exposure to loud sounds can cause hearing loss, all audible warning devices should be installed and operated in accordance with the standards established by the National Fire Protection Association.Safety FirstThis document provides all the necessary information to allow your Whelen product to be properly and safely installed. Before beginning the installation and/or operation of your new product, the installation technician and operator must read this manual completely. Important information is contained herein that could prevent serious injury or damage.Installation Guide:Howler™ Siren Speaker Bracket2011 Dodge 450051 Winthrop RoadChester, Connecticut 06412-0684Phone: (860) 526-9504Internet: Sales e-mail: autosale@Customer Service e-mail: custserv@®ENGINEERING COMPANY INC.Page 25/16-18X 1-1/4BOLT(QTY 2)STRAP (QTY 2)5/16FLAT WASHER (QTY2)5/16-18ELASTIC STOP NUT (QTY 2)CLAMP MOUNTFig 1ABOTTOM OF SPEAKER5/16-18X 1-3/4BOLT (QTY 1)5/16FLAT WASHER (QTY1)SPACER (QTY 1)5/16-18ELASTIC STOP NUT (QTY 1)STRAP (QTY 2)TOP OF SPEAKERFig 1BCHANNELVENT HOLES MUST FACE BOTTOMSTRAPSlide speaker forward with strap located to rear of channel.Securing the siren speaker to the bracket:Main Bracket:Secure the clamp mount that you secured to the siren speaker in step 1, to the main bracket as shown in figure 2.Support Bracket:Extend the WHITE (positive) and BLACK (negative) speaker wires to your siren amplifier and refer to the amplifiers instructions for connections.IMPORTANT! READ THESE WARNINGS BEFORE CONTINUING!The Howler™ Supplemental Siren was designed for use in high-risk areas such as an intersection. It is not intended to be, nor should be operated as a replacement or alternative to the vehicle’s primary siren.The low-frequency tones of the Howler™ demonstrate significantly different audio characteristics as compared to those of a traditional higher-frequency siren. While the low-frequency tones are better able to penetrate other vehicles, thus alerting drivers to the presence of the responding emergency vehicle, these tones may also penetrate into the responding vehicle itself. This could potentially expose the operator to increased noise levels.To help eliminate overexposure, the Howler™ siren has been designed with a built-in timing circuit. The Occupational Safety & Health Administration (OSHA) () provides information necessary to determine safe exposure times in Noise and Hearing Conservation, Section 1910.95(Occupational Noise Exposure). Until you have determined the safe exposure times for your specific application, this siren should be configured for the minimum operating time and operators should be required to use an approved hearing protection device. FAILURE TO FOLLOW THIS RECOMMENDATION COULD CAUSE HEARING LOSS!。
EDMI EM 710-MK2多脉冲多角度回声声音器产品说明书
Multibeam echo sounderHigh resolution seabed mapping systemSystem overviewThe EM 710-MK2 multibeamecho sounder is a high to very high resolution seabed mapping system capable of meeting all relevant survey standards. The coveragefor EM 710-MK2 is increased by replacing the receiver interface boards with new boards and new transceiver SW. The transducer arrays are the same. The system configuration can be tailored to the user requirements, allowing for choice of beam widths as well as transmission modes.The minimum acquisition depth is from less than 3 m below its transducers, and the maximum acquisition depth is approximately 2800 m, dependant upon array size. Across track coverage (swath width) is up to 5.5 times water depth, to a maximum of more than 3000 m.Echo sounder models There are three basic versions of the EM 710-MK2 system, with different range performances:• EM 710‑MK2 ‑ Full performance version.• EM 710S‑MK2 ‑ CW pulse forms only.• EM 710RD‑MK2 ‑ Short CW pulse only.Choice of beamwidthsThe along track beamwidth depends upon the chosen transmit transducer configuration with 0.5,1 and 2º available as standard. The receive beam width is either 1 or2º depending on the chosen receive transducer.Innovative acoustic principlesThe EM 710-MK2 operates at sonar frequencies in the 65 to 100 kHz range in shallow waters, and can use frequencies down to 40 kHz to extend coverage in deep waters. The transmit fan is divided into three sectors to maximize range capability, but also to suppress interference from multiples of strong bottom echoes.The sectors are transmittedsequentially within each ping,and uses distinct frequencies orwaveforms.EM 710S‑MK2 and EM 710RD‑MK2both use CW pulses of differentlengths. The full performance version,EM 710-MK2, supports even longer,compressible waveforms (FM sweep).Fully stabilized andfocused beamsThe system applies beam focusingto both transmit and receive beamsin order to obtain the maximumresolution also inside the acousticnear‑field.During transmission, focusing isapplied individually to each transmitsector with a focus point on the rangedefined by the previous ping, to retainthe angular resolution in the nearfield. Dynamic focusing is appliedto all receive beams. The transmitbeams are electronically stabilizedfor roll, pitch and yaw, while thereceive beams are stabilized for rollmovements.Controlled, dense andaccurate soundingsThe beam spacing may be set to beeither equiangular or equidistant.The maximum swath coverage may belimited by the operator either in angleor in swath width without reducingthe number of beams. A combinationof phase and amplitude bottomdetection algorithm is used, in orderto provide soundings with the bestpossible accuracy.The number of beams varies with thebeamwidth. The system generates400 soundings per swath for 1º RX,and 200 soundings for a 2º RXsystem. (800 and 400 in dual swathmode)TransducersThe active elements of theEM 710-MK2 transducers are basedupon composite ceramics, a designwhich has several advantages, inparticular increased bandwidth andtighter performance tolerances.The 1x2º and 2x2º versions canbe mounted on a pole for portabledeployment.For larger transducer versions arepermanent mounting like; flush withthe hull, in a blister or in a gondolaconstruction a possible solution.EM 710-MK2 can also be deliveredwith ice-reinforced transducer anda strengthen mounting frame forinstallation on icebreakers.Transceiver UnitThe EM 710-MK2 electronicssystem is a true wideband design.The transmitter circuits are fullyprogrammable to support anyfrequency or pulse form. The use ofFM sweep as a pulse form allowsfor more energy per pulse and thusincreased range performance, withoutany sacrifice of range resolution. Thenon-saturating and low noise receiversand A/D converters are of floatingpoint type, resulting in a dynamicrange of more than 140 dB. Theconventional TVG compensation isno longer needed. Filters, correlatorsand beamformers are fully digitalimplementations, and the beamforming method is by time delays, toallow for the wide frequency band ofthe system.The 2 x 2º RD version is deliveredwith a shorter (portable) transceivercabinet.Operator StationThe Operator Station is the HWS highperformance PC workstation usingWindows ®. The HWS is normallysupplied with a 24” industrializedLCD monitor. Support for a secondmonitor is included. A spillproofUS keyboard and a standard opticalmouse is normally supplied.Advanced functions• Integrated seabed acoustical imaging capability is included as standard. Software to use this data for automatic seabed classification is available from many third‑party suppliers.• A real time display window for water column backscatter is available. Logging of water column data and of raw stave data (before beamforming) is a system option.• A high density beam processing mode provides up to 400 or 200 soundings per swath. In order to make the soundings independent, a limited range window is set inside each beam for each sounding. In practice this is equivalent to synthetically sharpening the beam width. (Down to 25% in the outer beams)• The system generates two separate alongtrack swaths per ping. With dual swath the system can produce up to 800 ping.soundingsper• The Operator Station includes the necessary operator controls for setting up and running the system, data logging and system testing.• The Seafloor Information System (SIS) includes an extensive set of graphical displays for data quality control, as well as system calibration and other tools which are required. SIS supports on-line real-time data cleaning to improve the overall survey efficiency.• Post-processing software for the EM 710-MK2 is available from many third-party suppliers.390849 / Rev.C / November 2014Strandpromenaden 50P.O.Box 111N-3191Horten,NorwayKongsberg Maritime ASTelephone:+4733023800Telefax:+4733044753******************** Frequency range 40 to 100 kHz Max ping rate 30 HzSwath coverage sector Up to 140 degrees Min depth3 m below transducerRoll stabilized beams Yes, ±15°Pitch stabilized beams Yes, ±10°Yaw stabilized beams Yes, ±10°Sounding patternsEquiangular Equidistant High DensityMax depth (approximate values)0.5 x 1°EM710-MK2EM710S -MK2EM710RD -MK22800 m 1750 m 600 m CW transmit pulses 0.2 to 2 ms 0.2 to 2 ms 0.2 ms FM sweep pulseMax. 120 msNoNoTransducer choices 0.5 x 1°1 x 1°1 x 2°2 x 2°Availability Not EM 710RD‑MK2Not EM 710RD‑MK2All models All models TX dimensions (L x W x H)1940 x 224 x 118 mm 970 x 224 x 118 mm 970 x 224 x 118 mm 490 x 224 x 118 mm RX dimensions (L x W x H)970 x 224 x 118 mm 970 x 224 x 118 mm 490 x 224 x 118 mm 490 x 224 x 118 mm Max no. of soundings per ping (Dual swath mode)800800400400Kongsberg Maritime is engaged in continuous development of its products, and reserves the right to alter the specifications without further notice.Transceiver Unit dimensions (W x H x D)540 x 841 x 750 mm (including shockabsorbers)540 x 573 x 750 mm ‑ Standard for EM710RD‑MK2 2 x 2° version (Bulkhead mounting)EM ® is a registered trademark of Kongsberg Maritime AS in Norway and other countries.0.5 x 1°1 x 1° 1 x 2°2 x 2°Max coverage winter*2650250023502100Max coverage summer*3050285026502450Max depth winter*2650250023502200Max depthsummer*2800270025502400* Estimated depth and coverage for EM 710-MK2, based on BS= -20dB, NL= 45 dB, f = 40 kHz。

Ocean Way Recording began in 1968, as a showcase for Allen’s custom monitors.Allen needed impressive sounding material for his speakers so he began to record music that sounded dramatic! The studio business boomed and he met the demand with many rooms in several locations. At the peak of the studio business, Allen designed and owned four recording studio complexes.Five time Grammy® Award winning Allen Sides has personally recorded over 1,000 albums, many of which have become audiophile classics. He has worked with the finest and most famous artists of the last four decades. Albums recorded in Allen’s studios have sold over a billion copies. Allen’s hearing capabilities enables our engineers to translate every sonic nuance, bringing a new dimension and understanding to what is possible in high-end speaker design. His ears are our final design tool.Ocean Way Hollywood Ocean Way Nashville Ocean Way Record One Ocean Way St. Barts Through-out the history of Ocean Way Studios, we built the monitor systems for all the control roomsand private studios for selected elite cliental.These many accomplishments, paved the way forOcean Way AudioThe HR Series delivers “the” sound of Ocean Way Studios in a free standing design.

如1脚和8脚悬空，电压增益为20，则使用的元件最少。
如在1脚和8脚之间增加一只外接电阻和电容，便可将电压增益调为20-200间之任意值。
该芯片的优点是电压增益可调；外围元件少，一定程度上减少了杂散电容、电阻等元器件上的无谓损耗，且电路比较简单，成本低；低失真度，有利于音频信号的传输；静态功耗低，约为4mA,可用于电池供电。
其缺点是输出端电容耦合虽有益音频信号输出，但也在一定程度上对静态直流电流的隔断也会不利于维持预定的增益。

1.2.3声音接受
方案一：采用如图3声控电路。
利用驻极体话筒，将声音的强弱转化为电信号，并经三极管共射级放大电路放大。
静态时，根据图中参数可知三极管工作在饱和区。
动态时，如果环境的声音信号很弱，三极管仍处于饱和状态，B 点为低电平。
当环境声音信号达到一定强度时，集电极B 点电位随着声音而高低变化，当声音达到一定强度时，B 点输出高电位。
将此高电位做为单片机的驱动脉冲，驱动单片机工作。

方案二：采用如图4所示的语音输入双差分放大电路。
信号首先经过差分放大，再经过第二级放大。
自动增益控制部分利用场效应管工作在可变电阻区，漏源电阻受栅源电压控制的特性，利用压控放大器，整流滤波电路，场效应管闭环来实现。

方案三：采用含有两个与非门构成的延时控制电路。
当声音信号输入时，经过两级转换，实现后级所需的高电平，以保证延时顺利实现。
1.2.4红外传感
方案一：选用红外线光电开关。
运用对射形的方式，由投光器和受光器一对于一体，由物体是否遮断投光器和受光器的重合光轴来判断物体的有无。
此形检测距离最远，灵敏度高。
方案二：选用无线发射接收模块。
