FEATURES AND CONTROLS FRONT PANEL, PT1200 Clip Circuit and Indicator This special circuitry protects the amplifier and speaker system from being damaged by overdriving power levels. Indicator lights remind the user to reduce the volume when amplifier output is excessive. Power On/Off Phone Jack Lets you connect a pair of stereo headphones for private listening or cueing (monitoring) sound prior to "airing" it. Left and Right Output Level Controls Lets you adjust the sound levels for each channel Speaker A/B Selector Switches Permits you to select speakers attached to terminal set A, set B or both. REAR PANEL, PT1200 STEREO MONO GND INPUT R L 1 MONO 2 RL Stereo/Mono Selector Lets you select bridged mono input mode in combination with a mono signal source plugged into the Left channel, or conventional stereo operation with a stereo input signal. Input Jacks Lets you connect a variety of audio input sources via the balanced (XLR/6.35mm phone jack combinations) or unbalanced (RCA) inputs. RIGHT A LEFT - MONO + B +--+ SPEAKER VOLTAGE AC OUTLET FUSE Speaker terminals Permits hookup of two stereo pairs of speakers via the wire terminals. AC Outlet This switched outlet allows the electrical hookup of other units, with maximum load of 300W. Fan Cooling Cooling system is automatically activated whenever amplifier is turned on. This forced air cooling system rapidly exhausts interior heat, reducing operating temperature and aiding performance. 2 - PYLE PRO PT2000/1600/1200 Amplifier Owner's Manual INSTALLATION GUIDELINES Connecting the GND (Ground) screw terminal Connecting a mixer or preamplifier may cause excessive noise or hum in the amplifier output. To prevent this, connect one end of a low-capacitance shielded wire to the amplifier's ground screw (on the rear panel). Then connect the other end of this wire to the ground terminal on the mixer or preamplifier enclosure.

If the input signal is mono, connect the source via the LEFT input only (also marked "MONO" on the back of the amplifier). Then slide the Stereo/Mono selector switch to MONO and the signal will be routed through both channels.

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 the speaker wire you intend to connect to the amplifier. 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 wires 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. R L 4 OHMS MIN. IMPEDANCE SPEAKERS MUST BE OF SAME IMPEDANCE!
