[. . . ] Mic 4 / PHONO Allows you to adjust volume of connected Mic4 or turntable. XLR Balanced Microphone Inputs Connect up to four high-impedance microphones to your amplifier REAR PANEL Cooling Fan Cooling system is automatically activated whenever the amplifier is turned on. This forced air cooling system rapidly exhausts interior heat to reduced operating temperature Feedback Filter Left / Right Volume Controls the audio Lets you regulate the sound level of feedback. left and right speakers. 1/4" Stereo Input Jacks Connect stereo input sources (CD or DVD player, TV, etc. ) here, via a 1/4"(balanced) audio cable. Audio Input Jacks Connect input sources (CD or DVD player, TV, etc. ) here, via an unbalanced audio cable. [. . . ] A total speaker impedance greater than 16 ohms or less than 4 ohms can damage your amplifier or speakers. To determine total speaker impedance, you must first decide if you are going to connect the speakers in series, parallel, or a series, parallel combination. If you are connecting more than two speakers in series only or parallel only, be sure the total impedance does not exceed the amplifier's maximum impedance (16 ohms) or fall below the minimum impedance (4 ohms). A proper total impedance within the 4 to 16 ohms range can be achieved by combining series and parallel speaker connections. Preparing the speaker wires Finally, always use the shortest length of speaker wire possible of proper gauge. Usually, 18 gauge wire is adequate for length under 25 feet, while 16 gauge is used for greater length. To prepare the speaker wire, remove about 1/2 inch (12. 5mm) of insulation from the end of the speaker wire you are connecting to the amplifier. Then twist the exposed wire to secure all of the wire strands. Connecting Two Speakers in Series 1. Connect the right speaker's positive to the left speaker's negative terminal. 2. Connect the left speaker's positive to the speaker output jack's positive terminal. 3. Connect the right speaker's negative to the speaker output jack's negative terminal. Note: Determine the total speaker impedance of speakers you want to connect in series by adding up the individual impedance of all the connected speakers. If connecting two 4-ohm speakers in series, your total speaker impedance is 8 ohms. Connecting Two Speakers in Parallel 1. Connect the speaker's negative terminals together and then to the speaker output jack's negative terminal. 2. Connect the speaker's positive terminals together and then to the speaker output jack's positive terminal. Note: Determine the total speaker impedance of speakers you want to connect in parallel by dividing the impedance of one speaker by the number of speakers. If connecting two 8-ohm speakers in parallel, divide 8 (one speaker's impedance) by 2 (number of speakers). Your total speaker impedance is 4 ohms. Unbridged Connection Use this connection if you are connecting more than one speaker on the same channel or if you do not have highpower speakers. 1. Connect the speaker wires to the corresponding left and right speaker's positive (+) and negative (-) terminals. 2. Connect the other end of the left and right speaker's positive (+) and negative (-) wires to the amplifier's corresponding SPEAKER LEFT and SPEKAER RIGHT terminals for each channel. To connect speaker wires to the amplifier, turn the knob on the terminal counterclockwise until it stops, insert the bare wire inside the space between the knob and the amplifier, then turn the knob clockwise until it stops to secure it. 3. Make sure STEREO/MONO is set to STEREO. PYLE PRO PT-910 Amplifier Owners Manual - 3 Bridged Connection, Connecting The Speakers Without and With Transformers IMPORTANT: For a bridged connection, DO NOT connect any speaker wires to the BLACK SPEAKERS TERMINALS. NOTE: SPEAKERS RIGHT (+) on the amplifier is used as a negative (-) terminal for a bridged connection. Connecting The Speakers Without Transformers Use this connection if you have high power speakers that can handle a power output of 350 Watts.
