SPEAKER CONNECTION
One or more speakers (4, 8 or 16 Ohms) can be connected to the amplifier with or
without transformers. However, before you connect any speakers to the amplifier, the
total impedance must be calculated in order to avoid damage to the amplifier. A total
speaker impedance greater than 8 Ohms or less than 8 Ohms can cause this damage
to occur.
SYSTEM 1 : Single Speaker System
NOTE : Connect the speaker (+) to the amplifier's 8-Ohm terminal.
SYSTEM 2 : Two (or more) Speakers in Series
NOTE : Connect the speaker (+) to the amplifier's 8-Ohm terminal, depending on the
TOTAL IMPEDANCE of the two speakers. If each speaker has an impedance
of 4-Ohm, the total speaker impedance in this series configuration is 8 ohms.

SYSTEM 3 : Two (or more) Speakers in Parallel
NOTE : Connect the speaker (+) to the amplifier's 8-Ohm terminal, depending on the
TOTAL IMPEDANCE of the two speakers. If each speaker has an impedance
of 16-Ohm, the total speaker impedance in this series configuration is 8 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.
