Manual abstract: user guide PYRAMID PA1800X

Detailed instructions for use are in the User's Guide.

[. . . ] Please read this manual throughly before you attempt to set up and use the amplifier. It contains a range of installation suggestions as well as instructions to ensure safe usage. [. . . ] If you connect two pairs of speakers, be sure to follow these guidelines: · Speakers which are connected to the same channel are part of a pair, and must be of the same impedance. · Speakers connected to different channels are NOT part of a pair, and can be of different impedances. 1. Prepare the speaker wire by removing about 1 inch of insulation from the end of speaker wire you intend to connect to the amplifier. NOTE:Use 18-gauge speaker wire for lengths up to 25 feet; 16-gauge wire for lengths over 25 feet. 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. Connect the speaker wires to the amplifier's left and right speaker terminals according to the terminal color polarity. use RCA jacks CD PLAYER, TAPE PLAYER OR TUNER Connecting an equalizer or external signal processor Connect the processor's OUT to the amplifier's IN connector. EQ OR MIXER use 6. 35mm phone jacks R L 4 OHMS MIN. 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. [. . . ] Tightly secure four mounting screws (not supplied) through these four slots and into your standard electronics equipment rack. 6 Using the A/B Speaker Selector Switch You can listen to speakers on set A or set B individually or simultaneously. Simply push in or out the desired speaker set to make your selection. CAUTION: If the impedance of your speakers is 4 OHMS, do not use both the speaker A and speaker B terminal at the same time as the net impedance may be low enough to damage your amplifier. Replacing a fuse This amplifier requires a fuse with the proper rating for protection from power surges and short circuits. [. . . ]
