Using the power LED meters  
Bridged Mode Operation  
The meter pointer position indicates the amplifier output  
power. For ease of reading in dark environments, the meter  
is illuminated.  
This amplifier can operate in a mono bridged output mode, if  
your speakers can handle the following power output levels:  
120VAC,60Hz/230VAC,50Hz  
120VAC,60Hz/230VAC,50Hz  
120VAC,60Hz/230VAC,50Hz

Using the Channel 1 and Channel 2 Output Level controls  
Rotate output level gain clockwise to increase, or counter-  
clockwise to decrease the output power. To get the best  
performance with the least sound distortion, always adjust  
the output level gain so the meter's pointer does not  
continuously exceed the extreme right of the meter's scale.

As shown in the diagram below, connect the speaker's positive  
(+) to the amplifier's red speakers left (1/2) terminals and  
negative (-) to red speakers right (1/2) terminals.  
The speaker right (+) on the amplifier is used as a negative (-)  
terminal for a bridged connection.  
CAUTION: It is possible to overdrive the amplifier by  
setting output level gain too high, which may cause  
damage or failure.

About the internal protect circuitry  
Special clip circuitry incorporated into your PYLE PPA  
amplifier’s design protects the amplifier and speaker system  
from being damaged from overdriving power.  
DO NOT USE  
BLACK TERMINALS  
Under normal conditions, the amplifier’s clip indicator will  
flicker as the output power momentarily exceeds the level  
as set by the output level gain selector.

However, under excessive output conditions, the protect  
indicator lights remain on continuously, alerting you that  
the special clip circuitry has become active. When this  
occurs, you should simply reduce the output power level  
by rotating the Master Volume control counterclockwise.
