SYSTEM 3 : Two (or more) Speakers in Parallel NOTE : Connect the 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-Ohm, the total speaker impedance in this series configuration is 4 ohms. SYSTEM 4 : Four Speakers in Series and Parallel NOTE : Although the description above is for connecting two series pairs of 8 Ohms speakers in a parallel hook up, you may also select to combine a series pair and a parallel pair in a parallel hook up, simply be sure you have calculated the total impedance, and attach the speaker (+) circuit wire to the proper amp terminal. SYSTEM 5 : Connecting Speakers with Transformers NOTE : When the 25V or 70V constant line voltages are used, a line matching transformer must be used with each speaker, All transformers must be connected in parallel, never connect line transformers in series. 5 - Pyle Home PCM30A Manual
