User manual AUSTRALIAN MONITOR ACM250P

[. . . ] The "Protect" function is there to protect the amplifier from a high temperature problems which would only occur if the fan stopped working or became clogged up. In this very rare occurance, the protect LED will illuminate and the amplifier may shut down. The amplifier will automatically restart once it's internal temperature has fallen within "safe" limits. If the protect LED illuminates, it is best to switch the amplifier off, let it cool down and then try it again. [. . . ] When both outputs are used simultanously, ensure that neither output is loaded to maximum. Level Control Located to the left of the XLR input/output is a recessed screwdriver adjustable level control. 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 ACM250P includes both male and female 3 pin XLR connectors. 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.

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. Do not spill water or other liquids into or on the unit, or operate the unit while standing in liquid. Make sure power outlets conform to the power requirements listed on the back of the unit. 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. 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. 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 not covered by any warranty. Have gain controls on amplifiers turned down during power-up to prevent speaker damage if there are high signal levels at the inputs. [. . . ] Service Information Equipment should be serviced by qualified service personnel when: A. The equipment does not appear to operate normally, or exhibits a marked change in performance E. The equipment has been dropped, or the enclosure damaged. Engineered by Audio Telex Communications Pty Ltd, Sydney, Australia A. B.
