Clip Circuit and Indicator  
This special circuitry protects  
the amplifier and speaker  
system from being damaged  
by overdriving power levels.  
Indicator lights remind the  
user to reduce the volume  
when amplifier output is  
excessive.  
Your Pyle Pro amplifier can be operated in Stereo or Mono  
mode, depending on the input source. If the input signal is  
mono, connect the source via the LEFT input only (also  
marked “MONO” on the back of the amplifier). Then slide  
the Stereo/Mono selector switch to MONO and the signal  
will be routed through both channels.  
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 shielded 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.

two pairs of speakers, be sure to follow these guidelines:  
Connecting a CD or tape player or tuner  
In a normal installation, one would use the RCA JACKS for  
connecting a CD player, tape player or tuner

Bridged Mode Operation  
Using headphones  
Using the Left and Right Output Level controls  
This amplifier can operate in a mono bridged output mode,  
if your speakers can handle the following power output  
levels:  
To listen privately, or to monitor sound sources, connect  
a pair of low impedance stereo headphones (not supplied)  
with a 6.35 mm plug into the PHONES jack on the amplifier  
front panel.  
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.  
PT-2000: 350 watts  
PT-1600: 280 watts  
PT-1200: 200 watts  
Please listen safely. Follow these recommendations:  
CAUTION: It is possible to overdrive the amplifier by  
setting output level gain too high, which may cause  
damage or failure.  
Do not listen at extremely high volume levels. Extended,  
high-volume listening can lead to permanent hearing loss.  
As shown in the diagram below, connect the speaker's  
positive (+) to the amplifier's red speakers left (A/B) terminals  
and negative (-) to red speakers right (A/B) terminals.  
Always start with the volume control set to a LOW level  
BEFORE you put the headphones on. Then gradually increase  
the volume as necessary.  
About the internal clip circuitry  
The speaker right (+) on the amplifier is used as a negative  
(-) terminal for a bridged connection.  
Special clip circuitry incorporated into your Pyle Pro  
amplifier’s design protects the amplifier and speaker system  
from being damaged from overdriving power.  
Once you set the volume, do not increase it. Over a period  
of time, your ears adapt to the volume level, so a volume  
level which does not cause immediate discomfort may still  
be actually damaging your hearing.  
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.  
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 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.  
Connecting to standard AC power  
After making all other connections, set the POWER switch  
to OFF position. Then connect the power cord to a standard  
AC outlet.

HOOKUP  
Using the A/B Speaker Selector Switch  
Mounting the amplifier  
You can listen to speakers on set A or set B individually or  
simultaneously. Simply push in or out the desired speaker  
set to make your selection.  
This amplifier is designed to accept standard rack mounting  
installations. Two slots on each end of the front panel make  
it suitable for such an installation.

CAUTION: If the impedance of your speakers is 4 ohms,  
do not use both the speaker A and speaker B terminal at

to damage your amplifier!  
Tightly secure four mounting screws (not supplied) through  
these fours slots and into your standard electronics equipment  
rack.

Caring for your Pyle Pro Amplifier  
Turning the amplifier on  
1. Turn on the audio input source equipment which is  
connected to the amplifier INPUT jacks.  
Your Pyle Pro Amplifier is an example of superior design  
and craftsmanship. The following suggestions will help you  
care for your amplifier so you can enjoy years of use:  
2. Set the amplifier’s left and right output level gain controls  
to the minimum level settings.  
• Keep the amplifier dry. If it gets wet, wipe immediately.  
• Use the amplifier only in well-ventilated installations.  
• Handle the amplifier gently and carefully - do not drop!  
• Keep the amplifier away from dust and dirt.  
• Wipe occasionally with a damp cloth to keep it looking  
new. Do not use harsh chemicals, solvents or  
detergents!  
3. Push in the power switch to turn the amplifier on.  
Using the power meter (PT2000 and PT1600 only)  
The meter pointer position indicates the amplifier output  
power. For ease of reading in dark environments, the meter  
is illuminated.  
Replacing a fuse  
This amplifier requires a fuse with the proper rating for  
protection from power surges and short circuits. If the  
amplifier suddenly turns off or will not turn on, the fuse is  
probably blown.  
Using the meter range selector (PT2000 and PT1600 only)  
When output power is too strong, the meter's pointer might  
continuously swing to the extreme right and damage or  
reduce the accuracy of the meter. To protect the meter,  
you can use the meter range selector to control the amplifier's  
sensitivity to the input power signal. Leave the meter range  
switch in the OUT position to maintain a O dB gain for the  
meter. When output power is not strong, leave the meter  
range switch in the IN position to allow a +20dB gain.  
To replace the fuse:  
1. Unscrew the fuse compartment cap on the back of the  
amplifier.  
2. Remove the old fuse and replace it with an identical,  
serviceable fuse:  
PT-2000 = 7A/250V  
PT-1600 = 6A/250V  
PT-1200 = 5A/250V  
CAUTION: Never use a fuse with a higher rating.  
3. Replace the fuse compartment cap.
