<br> <BR> one, then the power outlet FireWire (L) and neutral (N) engage in anti. .<BR> <BR> Second, not sure that the power to rush to take power or normal boot. .<BR> <BR> Three electrical switches still open to connect the power supply. .<BR> <BR> Related explanation: <BR> <BR> many are in the firing line with a electrical fuse position, rear reverse will cause the fuse is still charged with the electrical situation. .Best to replace the fuse and double pole switches, which can cut off the firing line with the zero line. .Exhaust outlet is directly attached to electrical equipment, and in other protective devices connected to the regulator identified no abnormalities in the off state can be connected to each device. .Note Paicha good contact with the power supply. .Power amplifier at least make sure the volume switch is closed and the location of minimum. .Some more to the microphone input of the amplifier volume down his microphone. .<BR> <BR> Points: wiring the standard specification; first read through the device status, do not hurry to boot. .<BR> <BR> Fourth, the power cord exposed easily be stepped on kicked the place. .<BR> <BR> V. winding wire clutter, the signal line and power line is too close. .<BR> <BR> Six, forget sure the wiring is correct and secure. .<BR> <BR> Related explanation: <BR> <BR> when the power cord to be considered in the next to be pulled into, should first make it easy to be pulled bad, such as not to leave some reluctance to extend the length of .to avoid the force by pulling on a large angle to maximize the line is smooth, and sharp corners to avoid the slit; wire wrapped into a ball will be out of shape, but the line wrapped around a ball to use is not good. .When power is like the antenna wire, neatly rolled up and closely aligns parallel to each other when the wires perpendicular to the wire than the large disturbance. .Especially the signal lines and power lines entangling the worst case; wiring is not correct and not the firm is taboo in professional applications, reliable wire to make the work substantially reduce the chance of accidents. .<BR> <BR> Points: the role of the connection can not be ignored. .<BR> <BR> Seven, did not confirm whether the volume is off all equipment to the minimum position. .<BR> <BR> Eight, the boot sequence. .Such as the first open power amplifier. .<BR> <BR> September, the volume suddenly opened when debugging too big. .<BR> <BR> Related explanation: <BR> <BR> volume is turned up too high current would be the impact of, instant may kill equipment. .While there is comprehensive professional equipment protection, but do not take risks. .Equipment sometimes protection circuit has been the first action before the damage. .These three omissions and errors are likely to burn audio equipment, especially speakers. .<BR> <BR> Points: layers of caution. .<BR> <BR> Ten, in an attempt to use move, change equipment. .<BR> <BR> XI forget the effect of work status of monitoring equipment. .<BR> <BR> Second, the equipment does not work calmly unusual rush to cope. .<BR> <BR> Related explanation: <BR> <BR> the equipment is operating as not to move it as far as possible when not moving is not the time for the suspension; the status of monitoring equipment to observe whether there are any anomalies that is mainly .Note that there is no volume overload. .Abnormalities quickly and accurately to keep a cool head to take measures. .<BR> <BR> The safe use of audio equipment <BR> <BR> how to use the audio equipment it? .This article provides some useful recommendations for your reference: <BR> <BR> one. Note the use of machine conditions: <BR> <BR> general instructions in the machine will be listed in the use of machine conditions, such as: .<BR> <BR> 1. Ambient temperature: -10 ℃ - +40 ℃ <BR> <BR> 2. Relative Humidity: 50% - 80% <BR> <BR> 3. Power supply voltage: 198V-242V .<BR> <BR> 4. Power frequency: 50Hz-60Hz <BR> <BR> Specifically, it is required: <BR> <BR> 1. to avoid extremely low or high environmental temperature, the use of machines, to avoid .direct exposure to sunlight has been the surface of the machine. .<BR> <BR> 2. Humid environment to avoid the use of machinery in order to avoid premature failure of components inside the machine or machine prematurely rust. .<BR> <BR> 3. Must be confirmed prior to use the local power supply voltage and the local match. .<BR> <BR> II. .Note the use of the machine environment: <BR> <BR> 1. Avoid dust and vibration environments using the machine. .<BR> <BR> 2. In the machine should allow plenty of space around, in order to facilitate the cooling machine. .<BR> <BR> 3. For the power amplifier, special attention should be to maintain the smooth flow of cooling channels. .<BR> <BR> III. .The attention of the machine in use point: <BR> <BR> 1. In the sound system, attention should turn, shut down order. .Boot, should be open source and other pre-equipment, power amplifier and then open; shutdown, power amplifier should be off, then close the front audio and other equipment. .Audio equipment if the volume knob, boot, shut down, the best off the volume knob to the smallest place. .The aim is to reduce the power, shut down the impact of the speaker. .<BR> <BR> 2. Non-electric pull out, plug the signal plug. .So as not to damage the impact of the resulting machine or speakers. .<BR> <BR> 3. The machine if an abnormal course of their work sounds, immediately turn off the power and stop using it. .And invites qualified and experienced service personnel. .Do not open your machine, so as not to suffer more damage the machine or cause electric shock. .IV. Note that the machine maintenance: <BR> <BR> 1. .Do not use volatile solution, cleaning machines, such as gasoline, alcohol, wipe the surface of the machine, wipe the dust with a soft cloth. .When cleaning the machine casing and unplug the power first. .<BR> <BR> 2. .Machines generally are not waterproof, if wet, water, water stains use a dry cloth until the moisture dry before they can start work. .<BR> <BR> 3. .Do not place heavy objects on the machine so the machine deformation. .<BR> <BR> Five. .Safe use of machinery: <BR> <BR> 1. .Refrain from wet hands to pull out, plug the power cord to avoid electric shock. .<BR> <BR> 2. .Long periods of use, the power plug from the power outlet. .<BR> <BR> 3. .Do not let the iron needles, hairpins, coins and other metal conductive material falling into the machine, so as not to damage the machine. .<BR> <BR> 4. .When replacing the fuse the machine should be in strict accordance with request for a change, prohibited the use of undesirable substitutes. .<BR> <BR> 5. .Machine in use, should take place chassis safety ground. .<BR> <BR> 6. .The machine is prohibited in the case of overload or short circuit work. .<BR> <BR> 7. .Civilian power amplifiers generally have auxiliary power outlet on the back panel, not through its connection hair dryer, iron and other electrical appliances, it can only be used to connect audio devices. .<BR> <BR> 8. .Constant pressure in the power amplifier, its output will be higher output voltage and output leads are generally longer, so in use, make sure the output lead of the safe and reliable. .<BR> <BR> VI. .Attention to the protection of the power cord: <BR> <BR> 1. .Power cord to avoid being trampled, squeezed by a heavy object. .<BR> <BR> 2. .Never pull the power cord plug and strong distortions. .<BR> <BR> 3. .Remove the plug from the outlet, should grasp the plug to pull. .<BR> <BR> Short, modern audio equipment is high-tech products, must be well-maintained, safe use and correct operation. .For the joy of beauty, and to avoid unexpected losses. .<BR> <BR>.
