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
2.Connect the speaker wire to the speaker's positive and negative terminals.
NOTE: Most speaker terminals are either
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

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,
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
•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:
CAUTION:Never use a fuse with a higher rating.
