PCM20A  
40W MAX  
P.A. AMPLIFIER  
 
Your new PYLE HOME PCM Amplifier  
gives you the power and versatility you need in a professional sound system. The  
wide frequency response of it handles easily amplification of voice and music. The  
talkover function on MIC 1 and one Auxiliary Input on the front panel make it perfectly  
in meeting halls, auditoriums, sports events in school, and paging system in offices,  
anywhere you need to deliver special announcement with excellent sound.

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.
