When the knob is set at 0, there is no signal level output.O. TAPE IN - Unbalanced phono (RCA) input jacks designed for use with a tapeplayer, CD player, etc. These jacks sum the stereo left and right input signal to a mono signal useful for playingprerecorded music. Thetape/effects return to main andtape/effects return to monitor control the volume to these buses respectively.P. TAPE OUT - Unbalanced phono (RCA) output jacks designed for use with a tape recorder. They produce a mono signal. The rec out knob controls the tape out signal level.Q. PA 1 OUT / PA 2 OUT - These are speaker level output jacks designed to feed your main or monitor speaker enclosures. Remember, the minimum impedance load is 4 ohms . Connecting a load of less than 4 ohms may result in unsatisfactory performance such as overheating to the point of thermal shutdown. PA 1 Out jacks are intended for the main speakers. The use of the PA 2 Out jacks depends on the position of the PA 2 Assign switch.(See item E on page 5).R.POWER SWITCH -Turns the AC power ON and OFF. When the switch is in the OFF position, the SRM 6302 / 8302 is completely shut down.S. SUPPLY CORD - This is a grounding type supply cord to reduce the possibility of shock hazard. Completely unwind the cord from its cord wrap to prevent blocking air flow to the transformer. Be sure to connect the cord to a grounded receptacle. DO NOT ALTER THE AC PLUG.TAPE INPUT / OUTPUT JACKSPOWERONOFFRREAR PANEL OUT INL RTAPE O P SPARALLEL SPK JACKS150W4Ω MIN TOTALPARALLEL SPK JACKS150W4Ω MIN TOTALPA 2OUT PA 1OUTQParallel or series are the two basic ways which multiple speakers can be connected to a single power amplifier. When speakers are connected in parallel, their combined impedance decreases. For speakers wired in series the opposite is true, their combined impedance increases. Also, when speakers are wired in series, higher impedance speakers in the series draw more power from the amplifier than do speakers in the series with lower impedances. When speakers are wired in parallel, the opposite is true.At Fender®, we recommend connecting multiple speakers in parallel for several reasons. First, if one speaker fails, the others will continue to operate. Second, because in a series connection one speaker affects the output of the other speakers, unpredictable frequency response is a concern. Third, most speaker cabinets are already wired for parallel connections making parallel connections the most common wiring method.When using your SRM 6302 / 8302, be sure that the minimum load connected to each channel is 4 ohms. Below are two charts demonstrating how to calculate both parallel and series impedance.Additionally, power and audio signal cables are the most common sources of sound system failure. Well made and carefully maintained cables are essential to the reliability of the entire sound system. If long speaker cables are required, it is important to ensure the cable is sufficient to transfer all of the available amplifier power to the speakers rather than absorbing the power itself. As a rule of thumb, larger wires are better as they conduct more power to the speakers (larger wire has smaller gauge numbers).Below are two charts listing speaker wire gauges and recommendations for best results.*Example - If the speaker wire lengthrequired is between 25-50 feet (7.60-15.25 meters) and the speakerimpedance is 8Ω, the minimumrecommended speaker wire gauge is 16.100'-UP(30.5 m-UP)50'-100'(15.25-30.5 m)*25'-50'(7.60-15.25 m)10'-25'(3.05-7.60 m)0'-10'(0.00-3.05 m)SPEAKER WIRE GAUGESPEAKER IMPEDANCE [z]SPEAKERWIRELENGTHAWGResistance in Ω per foot(30.5 cm) @ 77º F (25º C)1816141210.00651.00409.00258.00162.001028.000640.831.322.103.325.278.3810121412141614*16181618181818184Ω*8Ω16ΩCross-Section[mm ]2The SRM 6302 / 8302 has a variety of connectors on its input / output panels.

IMPORTANT Heed all safety warnings when operating the SRM 6302 / 8302.2. Make sure the power switch is in the OFF position and all volume levels are in the 0 position.3. Next, plug the supply cord into a power source with the correct voltage.5. Connect the speaker cables from the SRM 6302 / 8302 PA out jacks to the input jacks of the speaker cabinets.6. Connect the cord(s) from any outboard gear, microphones or other signal source(s) to the appropriate input jack(s) on your SRM 6302 / 8302's.7. First, turn all outboard gear, instruments and other equipment ON, then the SRM 6302 / 8302.8. Increase volume controls and effects level controls to their desired levels, listening for feedback or ringing.9. When shutting down the SRM 6302 / 8302, turn OFF the SRM 6302 / 8302 first then any additional outboard gear, instruments or other equipment.

A ground loop usuallyoccurs if the separate pieces ofequipment are plugged into different AC circuits. Also, if the audio wiring is placed too close to the power cords, hums or buzzes can bleed into the system. Still, improperly maintained power and audio cables are yet another cause of bothersome noise. In order to help minimize stray hums and buzzes, here are some helpful hints.1. Keep all electronics connected to the sound system on the same electrical circuit.2. Keep audio signal cables away from the ACpower cords.3. Use balanced cables when applicable.4. Always plug the SRM 6302 / 8302 into agrounded AC electrical outlet.5. Be sure to use properly maintained cords andcables with the SRM 6302 / 8302.The SRM 6302 / 8302 is covered ingenuine Tolex®for long life and lastinggood looks.

前言尊敬的用户：您好！首先非常感谢您使用我们公司的系列产品，能够为您服务是我们的荣幸！为确保您正确使用本公司产品，请仔细阅读本手册。

手册采用图文并茂的方式，配合文字的插图详细直观地阐述产品的操作，由于产品生产日期、批次不同，说明可能会与实际使用的产品有差异，请以实物为准。

最后再次感谢您的惠顾与支持，同时也希望您在使用过程中反馈一些宝贵意见。

因为这些意见，能够使我们不断地去完善产品。

因为我们都呼吁安全第一，生命无价！也希望每一位驾驶员都遵守好交通规则，快快乐乐地出门，平平安安地回家！祝各位：万事如意，事事顺心！一、外观及按键功能描述（以下所有图片仅供参考）二、购买安装须知●产品为安卓操作系统汽车中控台车机专用（以下简称安卓车机）●请您先确认产品主机及配件是否完整，然后进行插电测试（测试时无需安装内存卡）●产品通过车机USB连接，内置安卓车机录像仪APP安装包，录像仪与安卓车机USB接口直连后，安装好APP即可正常使用；●产品本身无WiFi热点，使用方式为通过数据电源线连接车机，在车机上显示，通过车机热点或者手机热点，实现手机互联查看（具体操作步骤见后）●产品针对后加装的安卓车机开发，具体适配品牌或方案商的产品为展讯，鼎威、诺威达、腾实、恒昌通、迪恩杰、云智易联、卓芯威等；（原车自带的安卓车机因操作系统被锁定，未开源，不能安装外部软件，故无法使用。

）●录像仪的安装：撕去3M胶保护膜将膜贴于静电贴上，粘贴于后视镜附近的前挡风玻璃上，并保证良好视野。

部分车主因挡风玻璃贴膜，导致静电贴无法吸附挡风玻璃，可直接通过3M胶固定录像仪；部分录像仪支架可拆卸，录像仪固定之后，往下轻推录像仪(如下图），听到“咔哒”声后，可以使录像仪与支架分离。

录像仪安装时确认水平和垂直位置之后，固定录像仪；静电贴和3M胶贴在使用之后不宜再次使用，需要更换新的胶贴。

●连接电源：用电源数据线连接车机端和录像仪端。

（请务必使用原厂电源数据线）连接完成后，若录像仪指示灯变亮，则说明连接成功。
