INTRODUCTION SAFETY PRECAUTIONS Congratulations on your purchase of a QUANTUM AUDIO state-of-the-art power amplifier. Your selection of a QUANTUM AUDIO car audio product indicates a true appreciation of fine musical reproduction. Whether adding to an existing system or including your DB Drive amplifier in a new system, you are certain to notice immediate performance benefits. KEEP YOUR SALES RECEIPT A power amplifier’s performance is only as good as its installation.

FEATURES AND BENEFITS Line out DC Offset Protection Full range line outputs have been provided for convenient connection to additional amplifiers in the system. The outputs are buffered to reduce signal loss. Please note that the amplifier’s input level adjusts these level outputs. This circuit protects the output of the amplifier against DC voltage. If for some reason DC voltage is detected at the output stage, the amplifier will shut down protecting the speakers from direct current.

MOUNTING LOCATION Before you start the installation, it will be necessary to find a mounting location for the amplifier. Find a location in which the amplifier will receive adequate ventilation in order to dissipate the heat it develops during operation. Two popular mounting locations are in the trunk or under the seat. Select the location in which you wish to mount the amplifier.

SIGNAL CONNECTIONS SPEAKER CONNECTIONS Connect the RCA output of the head unit (AM/FM cassette player, CD, or DAT) to the RCA input terminals of the amplifier. IMPORTANT! The following speaker connection are for the amplifier in normal mono configuration.Make the speaker connections using speaker wire that is at least 16 gauge or heavier. To make these connections, we recommend high quality RCA cables, which are available at your local car audio retailer.

SPEAKER CONNECTIONS (QCA4400) REMOTE BASS CONTROL MODULE (OPTIONAL) Make the speaker connections using speaker wire that is at least 16 gauge or heavier. As with any audio component, proper phasing of the amplifier and speakers is essential for strong bass response. When connecting, make sure that positive (+) from the amplifier is connected to the positive (+) of the speaker, and the same for negative (-).

FINE TUNE THE SYSTEM ADJUSTMENTS AND SETTINGS The “Cozmik Series” amplifiers are equipped with built-in variable crossover networks allowing you to select the crossover mode (i.e. Low-Pass/Full/High-Pass or On/Off) and the desired crossover point. For example if you wish to drive a pair of subwoofers, you can select the “Low Pass” setting on the amplifier to filter out high frequencies. This will send only low frequencies to your subwoofers (see example settings below).

TROUBLE SHOOTING THE SYSTEM We have put together this trouble-shooting guide if you experience problems after installing the amplifier. Please keep in mind that the majority of problems incurred are caused by improper installation and not the equipment itself. In addition, there are many components in the system that could cause various signal problems such as inducted electrical noise and engine noise.
