5. g the risk of blowing high tensions fuses In the unlikely event that the DC fuse actuates the output transistors should be checked as it is probable that the amplifier has been subjected to very extreme conditions Important Safety Information 1 Save the carton and packing material even if the equipment has arrived in good condition Should you ever need to ship the unit use only the original factory packing 2 Read all documentation before operating your equipment Retain all documentation for future reference 3 Follow all instructions printed on unit chassis for proper operation 4 Do not spill water or other liquids into or on the unit or operate the unit while standing in liquid 5 Make sure power outlets conform to the power requirements listed on the back of the unit 6 Do not use the unit if the electrical power cord is frayed or broken The power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them paying particular attention to cords and plugs convenience receptacles and the point where they exit from the appliance 7 Always operate the unit with the AC ground wire connected to the electrical system ground Precautions should be taken so that the means of grounding of a piece of equipment is not defeated 8 Mains voltage must be correct and the same as that printed on the rear of the unit Damage caused by connection to improper AC voltage is no
6. ol One is provided per amplifier channel The level control is an input attenuation control normally used to match the amplifier to a wide variety of input signals In essence the amplifier is designed to receive a 700mv input signal however the level control can be used to increase the level for lower signals or decrease the level for higher input signals In normal use the level control is used as a set and forget master level control for the amplifier XLR Audio Input and Parallel Output The AMIS1202P includes both male and female 3 pin XLR connectors per channel While the female is normally used as the input to the amplifier both XLR s are connected in parallel so either will work When signal is connected to one XLR the other XLR becomes a line level output allowing the input signal to be distributed split to other amplifiers In some projects the same input may be looped through to multiple amplifiers using this method Up to 6 amplifiers can be looped together without any noticeable loss in level A distribution amplifier should be used when more than 6 amplifiers need to be looped The XLR s are wired as follows Pin 1 Shield Pin 2 Hot Positive Pin 3 Cold Negative Fuse Sizes Mains 230VAC 4 Amperes Slow Blow Notes The DC fuse is located on the circuit board This is a feature of the AMIS series amplifier which is equipped with a current limiting circuit preventing excessive DC current thus eliminatin
