congratulations…
On your purchase of a Pyramid Arctic Series amplifier. This amplifier extends the pyramid tradition into a new series of amps, designed from the ground up to deliver the power, performance, and flexibility the modern car audio enthusiast demands. When you check the list of features offered by the PB317X, PB417X, PB617X, PB717X, PB1217X, and PB1617X, you’ll know you made the right choice with a Pyramid Power amplifier.

precautions

  • Do not operate the amplifier when it is unmounted, Attach all audio system components securely within the automobile to prevent damage, especially in an accident.
  • Do not mount this amplifier so that the wire connections are unprotected, in a pinched condition, or likely to be damaged by nearby objects.
  • Before making or breaking power connections in your system, disconnect the vehicle battery. Confirm that your head unit or other equipment is turned off while connecting the input jacks and speaker terminals.
  • If you need to replace the power fuse, do so only with a fuse identical to that supplied with the amplifier. Using a fuse of a different type or rating may result in damage that isn’t covered in the manufacturer’s warranty.

Protection circuitry

  • The built-in protection circuitry in the pyramid Arctic amplifiers will disable the amplifier if it senses an input overload, a speaker short circuit, or extreme temperature conditions.
  • When the protection circuit is activated by any of these conditions, the Protection LED will be illuminated.
  • If this occurs, carefully inspect the system to determine the source of the problem.
  • If the shutdown was a result of a thermal overload condition, allow the amplifier to cool down before attempting to restart it.
  • If the shutdown was a result of an input overload or speaker short circuit, be sure to correct the condition before restarting.
  • The amplifier can be restarted by turning the remote power OFF and then ON again.

troubleshooting

No output.

  • Confirm that all terminal strip connections are secure and tight.
  • Check both in-line and built-in fuses. Both the +12V and the Remote terminals must have +12V referenced to the chassis ground.
  • Confirm that the audio signal source(car radio, equalizer, etc.) Is connected and is supplying an output signal. To check if the amp is supplying a signal, unplug the cables from the signal source(but leave them plugged into the amp).
  • Briefly tap the center pin of each disconnected RCA plug with your finger. This should produce a noise)feedback) in your speakers.

Only one channel works.                                                                               

  • Confirm that all terminal strip connections are secure and tight. Check the Balance control on the head unit(or other source) to verify that it is set to its midpoint.
  • If you are using the Low-Level RCA input, reverse the input plugs at the amplifier(i.e., switch the L with the R). If the channels that are silent switch to the other side, the problem is either in the head unit/other source or the connecting cables.

Weak output.

  • Readjust the Input Level Control(s) to better suit the input signal.

Noise in the audio.

  • If the noise is a “whine” whose pitch follows the engine speed, confirm that the amplifier and any other signal sources(heart unit, etc.) Are properly ground. If the noise is a “clicking” or “popping” noise whose rate follows the engine speed, this usually means that the vehicle is equipped with resistor spark plugs and wires, or that the ignition needs service.
  • Check the routing of the speaker and input wires to make sure they are not adjacent to wires that interconnect lights and other accessories.
  • If the above steps fail to improve or clear noise interference, the system should be checked by a professional mobile audio installer.

mounting and installation

When Your newly determined PYRAMID Arctic is a suitable Series location amplifier in your vehicle complete for the amp, required please remember to mount that hardware. it is a high-power electronic device capable of generating high heat.

For this reason, always choose a location in your vehicle that has low vibration, adequate ventilation, a minimum of dust, and no moisture. Be sure to mount the amp in such a manner as to allow reasonable airflow over the cooling fins.

Mark the location for the mounting screw holes by positioning the amp where you wish to install it and use a scribe (or one of the mounting screws) inserted in each of the mounting holes to mark the mounting surface for the mounting surface. If the mounting surface is carpeted, measure the hole centers and mark them with a felt tip pen.

Before attempting to drill the mounting holes, take note of any wires, lines, or other devices in your vehicle surface that may mounting be located screws behind and insert the mounting them. Tighten surface! the screws Then drill securely. pilot holes in the mounting

 When making electrical connections  to your amplifier, please observe  the following:
Use at least 8 gauge wire for power and ground connections. Wire the amplifier directly to the car battery. For the ground connection, use the shortest possible wire to a good chassis ground point. Wire the Remote connection to the auto start lead of your head unit, equalizer, or power antenna.

About power fuses: Pyramid Arctic  Series amplifiers feature built-in fuse systems. These fuses protect both the amplifier and the electrical system in your vehicle from fault conditions. If you ever need to replace the fuse in your Pyramid Arctic Series amp, use a fuse of the same type and rating. A different type or rating of fuse may result in damage or fire.
