INSTALLATION GUIDELINES
FEATURES AND CONTROLS
Phone Jack
Lets you connect a pair of stereo
headphones for private listening
or cueing (monitoring) sound prior
to “airing” it.
Left and Right Output Level Controls
Lets you adjust the sound levels for each channel
Clip Circuit and Indicator
This special circuitry protects
the amplifier and speaker
system from being damaged
by overdriving power levels.
Indicator lights remind the
user to reduce the volume
when amplifier output is
excessive.
Speaker A/B Selector Switches
Permits you to select speakers
attached to terminal set A, set B or
both.

Input connections
These amplifiers accept a broad 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
Connecting an equalizer or external signal processor
Connect the processor’s OUT to the amplifier’s IN connector.

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.

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 the 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 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 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 the amplifier). Then slide
the Stereo/Mono selector switch to MONO and the signal
will be routed through both channels.

CONNECTIONS USING
6.35 MM PHONE JACKS
(PT2000/1600 only)
AC Outlet
This switched outlet allows
the electrical hookup of
other units, with maximum
load of 300W.
Stereo/Mono Selector
Lets you select bridged mono input
mode in combination with a mono
signal source plugged into the Left
channel, or conventional stereo
operation with a stereo input signal.
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.
Input Jacks
Lets you connect a variety of audio input sources
via the balanced (XLR/6.35mm phone jack
combinations) or unbalanced (RCA) inputs.
Speaker terminals
Permits hookup of two
stereo pairs of speakers
via the wire terminals.
