Caring for your Pyle Pro Amplifier
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:
• 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!
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.
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.

Using the Left and Right 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.
CAUTION: It is possible to overdrive the amplifier by
setting output level gain too high, which may cause
damage or failure.
About the internal clip circuitry
Special clip circuitry incorporated into your Pyle Pro
amplifier’s design protects the amplifier and speaker system
from being damaged from overdriving power.
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.
Using the A/B Speaker Selector Switch
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.
CAUTION: If the impedance of your speakers is 4 ohms,
do not use both the speaker A and speaker B terminal at
the same time as the net impedance may be low enough
to damage your amplifier!
Using headphones
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.
Please listen safely. Follow these recommendations:
Do not listen at extremely high volume levels. Extended,
high-volume listening can lead to permanent hearing loss.
Always start with the volume control set to a LOW level
BEFORE you put the headphones on. Then gradually increase
the volume as necessary.
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.
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.
Mounting the amplifier
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.
Tightly secure four mounting screws (not supplied) through
these fours slots and into your standard electronics equipment
rack.
Turning the amplifier on
1. Turn on the audio input source equipment which is
connected to the amplifier INPUT jacks.
2. Set the amplifier’s left and right output level gain controls
to the minimum level settings.
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.
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.
Bridged Mode Operation
This amplifier can operate in a mono bridged output mode,
if your speakers can handle the following power output
levels:
PT-2000: 350 watts
PT-1600: 280 watts
PT-1200: 200 watts
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.
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.
