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.
