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.
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 2 : Two (or more) Speakers in Series
SYSTEM 1: Single Speaker System
NOTE : Connect the speaker (+) to the amplifier's 8-Ohm terminal.
5
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.
