PYLE Audio PCM30A User Manual

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 16 Ohms or less than 4 Ohms can cause this damage 
to occur.

SYSTEM 1 : Single Speaker System

           

NOTE : Connect the speaker (+) to the amplifier's 4-Ohm, 8-Ohm or 16-Ohm terminal, 

                        depending on the speaker being used.

SYSTEM 2 : Two (or more) Speakers in Series

         

  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 

                        cofiguration is 16 ohms.
