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.
