LIMITED TWO-YEAR CONSUMER WARRANTY Directed Electronics, Inc. promises to the original purchaser, to replace this product should it prove to be defective in workmanship or material under normal use, for a period of two years from the date of purchase by the dealer as indicated by the date code marking of the product PROVIDED the product was installed by an authorized Directed dealer.
FEATURES Five-band graphic equalizer with 18dB boost/cut. Switched input selector for two signal sources. Dual-function volume/fader control knob. Built-in remote output with turn-on delay for switching on amplifiers. Dedicated subwoofer output with adjustable low-pass crossover. 30 volts MOSFET switching power supply. Master volume control drives 4V RMS (front/rear) and 6V RMS (sub out). Gold-plated RCA input/output jacks. Half-din chassis for ease of installation.
INSTALLATION GUIDELINES 1. Read this manual carefully and in its entirety before installing this equalizer. ground and moving parts that can tangle the wires such as heater controls or wiper motors. 2. Always disconnect the battery or remove the fuses for circuits you will be working on. 6. Route all power and signal cables as far as possible from other vehicle wiring harnesses. Loom when appropriate. 3.
REAR PANEL FEATURES Power Connector 1. Remote Turn On Output - This output is intended to be the remote turn on for the system amplifiers and has a built in delay. Two to three seconds after the 2500 receives a (+)12V turn on signal, it will send a (+)12V turn on signal to the amplifiers. This feature is designed into the 2500 to eliminate system turn on pops that can occur when several components turn on at the same time. 2.

Make sure the main Source 1 unit is connected to the Source 1 inputs, then adjust the main source units volume to just below maximum. 2. Adjust the Source (top of unit) to setting and the volume control to setting. NOTE: 1 input gains the minimum 2500 master the maximum If connecting more than one input source to the 2500, use the Source 1 gain controls to match the input level of both sources. 3.
CROSSOVER AND FILTER ADJUSTMENTS The crossover and filter gain adjustments can be performed two different ways, by using a piece of audio test equipment called an RTA (Real Time Analyzer) or by listening to a familiar piece of music. The RTA is most commonly used to achieve the flattest possible system response in preparation for a sound off competition. Although an RTA may help in setting a flat system response it does not ensure the unit is tuned for your personal listening preferences.
volume of the system and affects all line level outputs to the amplifiers. Fader - To set the master volume/ fader control knob to the fader position, pull gently on it until a notched position is reached. It will then control the front-to-rear balance of the front and rear RCA output jacks. WARING! DO NOT use excessive force when using this knob or damage to its release mechanism may result. 2. Power On/Off LED - This LED will be illuminated when the 2500 is on. 3.
