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.

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

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.

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

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.

Protection Circuit and Indicator

The indicator will be illuminated when the amplifier is powered on and at turn- on 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.
