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
