2. Liquid Entry Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings 13 Power Lines An outdoor antenna should be located away from power lines 14 Damage Requiring Service The appliance should be serviced by qualified service personnel when A The power supply cord or the plug has been damaged or B Objects have fallen or liquid has been spilled into the appliances or C The appliance has been exposed to rain or D The appliance does not appear to operate normally or exhibits a marked change in performance or E The appliance has been dropped or the enclosure damaged 15 Servicing The user should not attempt to service the appliance beyond that described in the operating instruction All other servicing should be referred to qualified service personnel OPERATTING PRECAUTIONS Make sure the mains voltage is correct and is the same as that printed on the rear of the amplifier Unless otherwise specified when ordered amplifiers shipped to customers in North America operate on 120VAC 60Hz those shipped to customer in Europe and Asia operate on 220 240VAC 50Hz and those shipped to customers in Japan operate on 100VAC 50Hz Damage caused by connecting the amplifier to improper AC voltage is not covered by any warranty Always power down and disconnect the amplifier from mains voltage before making connections Itis always a good idea to have the gain controls turned down during

7. ight glow means the amp is peak limiting or reducing gain to prevent severely peak wave form reaching the loudspeakers 5 SIGNAL LED This green LED lights when its channel produces an output signal of about 4 volts RMS or more 1 volt or more at the input with OdB attenuation indicating that there is amplified signal present in the amplifier It is useful in determining whether a signal is reaching and being amplified by the power amplifier Note If the signal reaching the power amplifier is bellow 50 100mV the LED will not be active Also if the amplifier goes into protective mode this LED will not active 6 POWER LED The green Power LED indicates that the channel is operational It lights under normal operation when a channel is not in protection mode If the Power LED goes off there is no signal at the module output point 7 AC POWER SWITCH Power ON OFF switch 8 9 SPEAKER JACK Connect same polarity of speaker as terminal of connection of Left Right speakers 10 CH 1 2 INPUT JACK Balanced amp Unbalanced signal input of CH 1 amp 2 Can use XLR plug amp 6 3 mm plug 11 STEREO MONO BRIDGE SWITCH Slide switch to select stereo or bridged mono mode 12 AC Mains Power Input Socket AC115 230V 50 60Hz Check the power source of AC Voltage before connections 13 Power Fuse When power is overload this Current will auto broken circuit and all LED at front panel will turn off Now you should turn off t
