CAUTION! Do not use balanced and unbalanced inputs simultaneously!!

Bridged Mode Operation

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

PPA 200: 2000 watts

PPA 300: 3000 watts

PPA 450: 4500 watts

As shown in the diagram below, connect the speaker's positive

(+)to the amplifier's red speakers left (1/2) terminals and negative (-) to red speakers right (1/2) terminals.

The speaker right (+) on the amplifier is used as a negative (-) terminal for a bridged connection.

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 1 and Channel 2 output level gain controls to the minimum level settings.

3.Push in the power switch to turn the amplifier on.

Using the power LED meters

The meter pointer position indicates the amplifier output power. For ease of reading in dark environments, the meter is illuminated.

Using the Channel 1 and Channel 2 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 protect circuitry

Special clip circuitry incorporated into your PYLE PPA 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 protect 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.

CAUTION! Do not use balanced and unbalanced inputs simultaneously!!
