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.

Input connections
These amplifiers accept a board 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.
use RCA jacks

Connecting an equalizer or external signal processor
Connect the processor's OUT to the amplifier's IN connector.

Stereo or Mono Inputs
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 amplifier). Then slide the
STEREO/MONO selector switch to MONO and the signal will
be routed through both channels.
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 speaker wire you intend to
connect to the amplifier. Then twist the exposed wire to
secure all the wire strands.
NOTE: Use 18-gauge speaker wire for lengths up to 25
feet; 16-gauge wire for lengths over 25 feet. It is
recommended that you use the shortest length of wire
possible.
2. Connect the speaker wire to the speaker's positive and
negative terminals.
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.

Bridge Mode Operation
This amplifier can be operated in mono bridged output
mode, if your speakers can handle the following power
output levels:
PT2800: 370 watts
PT2400: 230 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 righr (+) on the amplifier is used a negative
(-) terminal for a bridged connection.
NOTE: IT IS SUGGESTED TO USE A 8-OHM SPEAKER FOR
THE ONE CHANNEL BRIDGE HOOKUP. IF YOU CONNECT
TWO CHANNELS' BRIDGE HOOKUP, PLEASE MAKE SURE
THE SPEAKER IMPEDANCE MUST BE 8-OHM MINIMUM.

Using headphones
To listen privately, or to monitor sound sources, connect
a pair of low impedance stereo headphones (not supplied)
with 6.35mm 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 voulume as necessary.
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 four 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 jack.
2.Set the amplifier's left and right output level gain controls
to the minimum level settings.
3.Press the power switch to turn the amplifier on.
Using the power meter
The meter LED dispaly position indicate the amplifier output
power.
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 leaset sound distortion, always
adjust the output level gain so the meter's level indication
does not continuously exceed to the extreme right.
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 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, altering 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.
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 away from dust and dirt.
• Wipe occasionally with a damp cloth to keep it looking
new.
Do not use harsh chemical, 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 properly blown.
Remove the old fuse and replace it with an identical,
serviceable fuse:
PT-2800 = 7A (110-120V) OR 3.5A (220-240V)
PT-2400 = 5A (110-120V) OR 2.5A (220-240V)
CAUTION:Never use a fuse with a higher rating.
