#5 Both the DCA and DCM series amplifiers feature thermostatic controls that will shut the amp down if it should become too hot. This offers appropriate protection from improper operating conditions. The Front "TEMP" light will come on to indicate that the amp has been shut down. Allow fifteen minutes for the amp to cool. Upon properly cooling down the amplifier will reset itself and again resume normal operation. Note: you should check to determine the reason For over-heating. Usual causes are poor ventillatidn, speaker impedance below recommended minimums, direct sun overheating the chassis, etc. #6 You will note that both series amplifiers do not have a ground reversal switch. It has been eliminated to prevent shock hazard. All grounding is done through the ground lug of the 3 conductor A.C. plug. This is the safe and proper way to ground all electrical appliances. If for any reason you require an A.C. line phase reversal, you may do so by utilizing a 3 to 2 prong adaptor and Flipping the plug. NEUER DEFEAT THE USE OF THE 3RD PIN GROUND LUG ON THE AC RECEFTICLE. WHEN USING A 3 TO 2 PRONG ADAPTOR SE SURE THE GROUND LINE IS PROPERLY CONNECTED TO A "GOOD" GROUND. THIS IS TO PROUIDE THE BEET MARGIN OF SAFETY AND PERFORMANCE FROM YOUR AMP. #7 Always be sure you are plugging the amp into the proper A.C. voltage. Be sure the voltage is properlu regulated and will not Fluctuate more than 10% above or below the 120U requirement cf the DCA/DCM AMP. If the amplifier is going to be powered From a generator, be sure the generator has proper "electronic" voltage regulation and that the A.C. lines are free From voltage surges. Note: It is recommended that you use a surge supressor and broad band noise supressor, especially when operating the amp off a oenerator. This will provide further protection against voltage surges and spikes. #6 Whenever turning on or off uour CARUIN amp you should follow this rule: "Last on - First off." This means that you will turn on all associated pre-amp (mixers) and associated equipment prior to turning on the amp. When uou are Finished with a performance, the amplifier will be the first item shut down. Following this proceedure will help eliMinate pops & power surges (created by preceding equipment) that are annouing to audiences and potentially harmful to speakers. #S Do not remove the amplifiers cover at any time while the amp is plucced in or powered up. THERE ARE POTENTIALLY LETHAL UOLTAEES INSIDE THE AMP.
