[. . . ] Then twist the exposed wire to secure all the wire strands. NOTE:Use 18-gauge speaker wire for lengths up to 25 feet; 16-gauge wire for lengths over 25 feet. It is recommended that you use the shortest length of wire possible. 2. Connect the speaker wire to the speaker's positive and negative terminals. NOTE:Most speaker terminals are either color-coded or have a mark that indicates the terminal's polarity. Usually positive terminals are red or have a plus symbol (+), and negative terminals are black or have a minus symbol (-). 3.

IMPEDANCE SPEAKER MUST BE OF SAME IMPEDANCE. use RCA jacks EQ OR MIXER 5 Bridge Mode Operation (PA1000X/PA1800X) The PA1000X and PA1800X can be operated in mono bridged output mode, if your speakers can handle the following power output levels: PA1000X: 320 watts PA1800X: 420 watts As shown in the diagram below, connect the speaker's positive (+) to the amplifier's red speakers left (A/B) terminals and negative (-) to red speakers right (A/B) terminals. The speaker righr (+) on the amplifier is used a negative (-) terminal for a bridged connection. NOTE: IT IS SUGGESTED TO USE A 8-OHM SPEAKER FOR THE ONE CHANNEL BRIDGE HOOKUP. IF YOU CONNECT TWO CHANNELS' BRIDGE HOOKUP, PLEASE MAKE SURE THE SPEAKER IMPEDANCE MUST BE 8-OHM MINIMUM. Turning the amplifier on 1. Turn on the audio input source equipment which is connected to the amplifier INPUT jack. 2. Set the amplifier's left and right output level gain controls to the minimum level settings. 3. Press the power switch to turn the amplifier on. Using the power meter (PA800X/PA1000X/PA1800X) The meter POINTER (PA800X/PA1000X) and/or LED (PA1800X) position indicate the amplifier output power. For ease of reading in dark environments, the VU meter (PA800X/PA1000X) is illuminated. Using the meter range selector (PA800X/PA1000X) When output power is too strong, the meter's pointer might continuously swing to the extreme right and damage or reduce the accuracy of the meter. [. . . ] If the amplifier suddenly turns off or will not turn on, the fuse is properly blown.
