INSTALLATION GUIDELINES  
Connecting the GND (GROUND) screw terminal Connecting  
a mixer or preamplifier may cause excessive noise or hum  
in the amplifier output. To prevent this, connect one end  
of a low-capacitance shield wire to the amplifier's ground  
screw (on the rear panel). Then connect the other end of  
this wire to the ground terminal on the mixer or preamplifier  
enclosure.

STEREO OPERATION  
Bridged Mode Operation  
This amplifier can operate in a mono bridged output mode, if  
your speakers can handle the following power output levels:  
MONO OPERATION  
SWITCH IN “MONO” POSITION  
SWITCH IN “STEREO” POSITION  
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.  
NOTE: The extra amplifier output of 6.35mm phone  
jacks can not be used for the bridged connection. It can only  
be used in normal (non-bridged) operation as a stereo speaker  
output.

DO NOT USE  
BLACK TERMINALS  
Your Pyle Pro amplifier can be operated in Stereo, Mono or  
Bridged mode, depending on the input source. If the input  
signal is mono, slide the Stereo/Mono/Bridged selector  
switch to MONO and the signal will be routed through both  
channels. If you wish to run the amplifier in bridged output  
mode, slide the switch to Bridged.

CHANNEL 1  
INPUT ONLY  
You can connect 4 Ohm, 8 Ohm or 16 Ohm speakers to  
Channel 1 and/or Channel 2 of the amplifier. If you connect  
two pairs of speakers, be sure to follow these guidelines:  
• Speakers which are connected to the same channel are  
part of a pair, and must be of the same impedance.  
DO NOT USE  
BLACK TERMINALS  
STEREO SIGNAL SOURCE

• Speakers connected to different channels are NOT part  
of a pair, and can be of different impedances.  
1. Prepare the speaker wire by removing about 1 inch of  
insulation from the end of the speaker wire you intend to  
connect to the amplifier. Then twist the exposed wire to  
secure all the wire strands.  
NOTE: Use 16-gauge speaker wire for lengths up to25  
feet; 14-gauge wire for lengths over 25 feet. It is  
recommended that you use the shortest length of wire  
possible.

Connecting to standard AC power  
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.

Turning the amplifier on  
1. Turn on the audio input source equipment which is  
connected to the amplifier INPUT jacks.  
Special clip circuitry incorporated into your Pyle Pro  
amplifier’s design protects the amplifier and speaker system  
from being damaged from overdriving power.

2. Set the amplifier’s Channel 1 and Channel 2 output level  
gain controls to the minimum level settings.  
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.

3. Push in the power switch to turn the amplifier on.  
Using the power blue LED meters (without PT1201X)  
The meter pointer position indicates the amplifier output  
power. For ease of reading in dark environments, the meter  
is illuminated.  
However, under excessive output conditions, the clip  
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.
