Limited warranty
Please read this manual throughly before you attempt to set up and use the amplifier. It contains a
range of installation suggestions as well as instructions to ensure safe usage. Installed properly, you
can expect years of trouble-free service from this product.
FEATURES AND CONTROLS
Channel 1 and Channel 2 Power LED Display
Indicate the output signal level for each channel.

Output Level Controls
Lets you adjust the sound levels
for each channel.
These indicator illuminates when the
associated channel has been overloaded.
Fan Cooling
Cooling system is automatically activated
whenever amplifier is turned on. This forced
air cooling system rapidly exhausts interior
heat, reducing operating temperature and
aiding performance.

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 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.
LOW CAPACITANCE SHIELOEO WIRE
Input connections
These amplifiers accept a broad range of input sources,
including Compact Disc (CD) players; DVD, Cassette, Reel­
to-Reel or other tape players; Radio Tuners; Equalizers;
Signal Processors.
Connecting a CD or DVD or tape player or tuner
In a normal installation, one would use the RCA JACKS for
connecting a CD player, DVD, tape player or tuner.

Stereo or Mono Inputs
Your PYLE PPA 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 1 and/or Channel 2 of the amplifier, total speaker
impedance must not be lower than 4 Ohms per channel for
Stereo and Parallel Mono modes, and 8 Ohm for Mono Bridge
mode. 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 t025
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.
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.
STEREO OPERATION
SWITCH IN "STEREO" POSITION
NOTE: The total speaker load
must be at least 4 Ohms per
channel in this mode.

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