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.

Input connections
These amplifiers accept a broad range of input sources,
including Compact Disc (CD) players; Cassette, Reel-to-Reel
or other tape players; Radio Tuners; Equalizers; Signal
Processors.
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.

Stereo or Mono Inputs
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.
Speaker connections
You can connect 4 Ohm, 8 Ohm or 16 Ohm speakers to
Channel A and/or Channel B 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.
• 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.
2. Connect the speaker wires to the speaker's positive and
negative terminals.

Bridged Mode Operation
This amplifier can operate in a mono bridged output mode, if
your speakers can handle the following power output levels:

CHANNEL A
INPUT ONLY
CAUTION! Do not use
balanced and unbalanced
inputs simultaneously!!
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 Channel A and Channel B output level
gain controls to the minimum level settings.
3. Push in the power switch to turn the amplifier on.
Using the power meters
The meter pointer position indicates the amplifier output
power. For ease of reading in dark environments, the meter
is illuminated.
use RCA jacks

NOTE: Most speaker terminals are either color-coded
or have a mark that indicates the terminal's polarity.
Usually positive terminals are red or have a plus symbol
(+), and negative terminals are black or have a minus
symbol (-).
3. Connect the speaker wires to the amplifier's left and
right speaker terminals according to the terminal color
polarity.

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.

Using the Left and Right Output Level controls
Rotate output level gain clockwise to increase, or counterclockwise 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.

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!
Resetting the circuit breaker
This amplifier employs a circuit breaker for protection from
power surges and short circuits. If the amplifier suddenly
turns off or will not turn on, check the circuit breaker. If
it is tripped, check and correct for a short or overload
condition. Wait for the amplifier to cool, then press the
circuit breaker RESET button on the back of the amplifier.
