System 2: Two (or more) speakers in series 1. Connect the LEFT SPEAKER (-) to the amplifier COMMON terminal. 2. Connect the LEFT SPEAKER (+) to the RIGHT SPEAKER (-). 3. Connect the RIGHT SPEAKER (+) to the amplifier's 4 Ohm, 8 Ohm or 16 Ohm terminal, depending on the TOTAL IMPEDANCE of the two speakers. If each speaker has an impedance of 8 Ohms, the total speaker impedance in this series configuration is 16 Ohms. LEFT speaker RIGHT speaker THIS EXAMPLE SHOWS 4 OHM SPEAKERS, TOTAL IMPEDANCE IS 8 OHMS FUSE COM 4Ω 8Ω 16Ω 70V 8Ω + 8Ω - GND IN 110 OUT LINE C NOTE: ADDITIONAL SPEAKERS MAY BE INCLUDED IN SERIES, BUT IT IS NECESSARY TO CALCULATE TOTAL IMPEDANCE, AND CONNECT THE SPEAKER CIRCUIT TO A TERMINAL OF APPROPRIATE IMPEDANCE. FOR EXAMPLE, IF THREE SPEAKERS OF 4 OHMS ARE USED, TOTAL IMPEDANCE IS 12 OHMS - YOU SHOULD CONNECT TO THE 16 OHM TERMINAL. System 3: Two (or more) speakers in parallel 1. Connect the LEFT SPEAKER (-) to the RIGHT SPEAKER (-). 2. Connect both the LEFT SPEAKER (-) and the RIGHT SPEAKER (-) to the amplifier COMMON terminal. 3. Connect the LEFT SPEAKER (+) to the RIGHT SPEAKER (+). 4. Connect both the LEFT SPEAKER (-) to the RIGHT SPEAKER (+) to the amplifier 4 Ohm, 8 Ohm or 16 Ohm terminal, depending on the TOTAL IMPEDANCE of the two speakers. If each speaker has an impedance of 8 Ohms, the total speaker impedance in this parallel configuration is 4 Ohms.

Group the four speakers in two pairs. 2. Connect one pair of speakers in series (see system 2, above). Note total impedance in chart below. 3. Connect one pair of speakers in parallel (see system 3, above). Note total impedance in chart below. 4. Connect the speakers' (-) terminals to the amplifier COMMON terminal. 5. Connect the speakers' (+) terminals to amplifier's 4 Ohm, 8 Ohm or 16 Ohm terminal, depending on the TOTAL IMPEDANCE of the four speakers. See the chart below for some sample system suggestions: PARALLEL speaker pair (net impedance for pair) 8Ω ∗ 8Ω ∗ 4Ω∗ 8Ω ∗ 8Ω ∗ 4Ω∗ 16Ω ∗ 16Ω ∗ 8Ω∗ 16Ω ∗ 16Ω ∗ 8Ω∗ SERIES speaker pair (net impedance for pair) 8Ω ∗ 8Ω ∗ 16Ω∗ 16Ω ∗ 16Ω ∗ 32Ω∗ 4Ω ∗ 4Ω ∗ 8Ω∗ 8Ω ∗ 8Ω ∗ 16Ω∗ TOTAL IMPEDANCE isnysttheims type 3.∗Ω 3 Use this amp terminal 4Ω 4Ω 4Ω 8Ω PARALLEL LEFT speaker NOTE: This diagram is for THE FIRST THREE examples in chart. In this case, 4 Ohm terminal is used. Your system impedance may vary depending on the impedances of the individual speakers, and may require hookup to the 8 or 16 Ohm terminals. PARALLEL RIGHT speaker SERIES SERIES RIGHT speaker LEFT speaker FUSE COM 4Ω 8Ω 16Ω 70V 8Ω + 8Ω - GND IN 110 OUT LINE C Series/parallel variations Although the description above is for combining a series pair and a parallel pair in a parallel hookup, you may also elect to combine two series pairs in a parallel hookup. Simply be sure you have properly calculated the total impedance, and attach the (+) speaker circuit wire to the proper amp terminal. For example, if you use two pairs of 8 Ohm speakers in series each pair, the impedance for each pair is 16 Ohms. Connected in parallel to the amp terminals, the TOTAL impedance is 8 Ohms, so you should connect these to the 8 Ohm terminal. PYLE PRO PT610 Amplifier Owner's Manual - 3
