material. It can be used for live bands,
office paging systems, public
announcements, or a variety of other
installations.

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.

Protection Circuit and Indicator

The indicator will be illuminated when
the amplifier is powered on and at turn­on delay status; the indicator will be
turned off after internal outputs are
connected. The indicator will also be
illuminated when the amplifier has
abnormal problems, such as overload
or excessive heat.

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.

Input connections

These amplifiers accept a broad range of input sources,
including Compact Disc (CD) players; DVD, Cassette, Reel­to-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.

use RCA jacks

Connecting an equalizer or external signal processor

Connect the processor’s OUT to the amplifier’s INPUT

Stereo or Mono Inputs

Your PYRAMID XPA 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. 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 to25
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.
