INSTALLATION GUIDELINES  
Stereo or Mono Inputs  
Bridge Mode Operation  
Using the power meter  
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.  
This amplifier can be operated in mono bridged output  
mode, if your speakers can handle the following power  
output levels:  
The meter LED dispaly position indicate the amplifier output  
power.  
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.  
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.  
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.  
CAUTION:It is possible to overdrive the amplifier by  
setting output level gain too high, which may cause  
damage or failure.  
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.

About the internal clip circuitry  
EQ OR MIXER  
Special clip circuitry incorporated into your amplifier's  
design protects the amplifier and speaker system from being  
damaged from overdriving power.

HOOKUP  
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.

Input connections  
Speaker 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.  
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:  
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.  
• Speakers which are connected to the same channel are  
part of a pair, and must be of the same impedance.  
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.  
Using the A/B Speaker Selector Switch  
You can listen to speakers on set A or set B individually or  
• Speakers connected to different channels are NOT part  
of a pair, and can be of different impedances.  
simultaneously. Simply push in or out the desired speaker  
set to make your selection.  
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.  
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.  
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  
use RCA jacks  
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.  
CD PLAYER, TAPE PLAYER  
OR TUNER  
impedance may be low enough to damage your amplifier.  
Please listen safely. Follow these recommendations:  
Caring for your Pyle Pro Amplifier  
Do not listen at extremely high volume levels. Extended,  
high-volume listening can lead to permanent hearing loss.  
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.  
2. Connect the speaker wire to the speaker's positive and  
negative terminals.  
Always start with the volume control set to a LOW level  
BEFORE you put the headphones on. Then gradually increase  
the voulume as necessary.  
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 (-).  
Connecting an equalizer or external signal processor  
Connect the processor's OUT to the amplifier's IN connector.  
Connecting to standard AC power  
Do not use harsh chemical, solvents or detergents!  
After making all other connections, set the POWER switch  
to OFF position. Then connect the power cord to a standard  
AC outlet.  
EQ OR MIXER  
3. Connect the speaker wires to the amplifier's left and  
right speaker terminals according to the terminal color  
polarity.  
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.  
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.  
use XLR/6.35mm combo jacks
