OWNER’S MANUAL
INTRODUCTION |
PYRAMID SERIES |
Thank you for purchasing a Pyramid car audio amplifier.
Rest assured you have purchased a quality product designed and engineered to give you many years of uncompromised musical service.
This amplifier has been designed using the latest in electronic technology available today and will provide you with years and years of high quality sound level amplification and reproduction.
This amplifier have been designed with a fully regulated 100% MOSFET Power supplies assuring extremely quick switching response and self protection with soft starting power turn on.
A FEW WORDS ABOUT PROTECTION CIRCUITRY.
Advanced protection circuits have been designed into all Pyramid amplifiers. The protection circuitry will disable the amplifier if it senses an input overload, speaker short circuit short or extreme high temperature conditions.
When the protection circuit is in operation the LED indicator on the unit will light indicating that the amplifier has gone into a self preservation mode.
At this time please check your system to see what is causing the protection circuit to fire. The amplifier can be reset by turning the remote power off and then on again. If the system shuts down because of a thermal overload condition, allow the amplifier to cool down before restarting. If the amplifier shutdown because of an input overload or speaker short circuit please be sure to correct these conditions before restarting the amplifier.

2-OHM OPERATION |
PYRAMID SERIES |
This unit was designed to operate efficiently at loads down to 2 ohms. What this means is that you can do an installation of FOUR-8 ohm speak-
ers per channel using parallel wiring or TWO-4 ohm speakers per channel in parallel.
When operating at 2 ohms, the amplifier to increase their power output by approximately 50 percent. The current draw of the amplifiers will also increase by about the same as amount. Be sure that you have enough current to run the amplifier into a 2 ohm load otherwise distorted music will be reproduced.
Do not use a 2 ohm load in the bridged mode.
The amplifier accepts 4-8 ohms only in the bridged mode.
