OWNER’S MANUAL models D600 D800
CONGRATULATIONS Congratulations for choosing a Directed Audio power amplifier from Directed Electronics, the industry leader in high quality automotive security and audio equipment since 1990. Directed Audio power amplifiers continue to set new standards of performance, reliability, and affordability in the mobile electronics industry.
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 Super-efficient Class D PWM design runs much cooler than conventional amps. High-speed MOSFET switching power supply. High-current complimentary Class D MOSFET outputs stable into one ohm loads. (D600 stable into two ohm load.) Thermal, DC offset, reverse polarity, and short circuit protection with status LED. Continuously variable 12dB/ octave low-pass crossover. Switchable subsonic filter, 24dB/octave . Switchable 8 dB bass EQ function.
INSTALLATION GUIDELINES 1. Please read this owner’s manual carefully before installing this amplifier. 2. Disconnect the battery ground terminal prior to making any electrical connections. 3. Check for any hazards or obstructions such as gas tanks, fuel or brake lines, and wiring harnesses before mounting the amplifier. 4. Pick a mounting location that will provide adequate access and ventilation and protect the amplifier from heat, moisture, and dirt. 5.
tronics and the lower your speaker load, the more heat is generated. For low impedance speaker applications or restricted ventilation installations, an external cooling fan may be advisable. 9. Battery and ground connections to the vehicle should be made with crimped ring terminals of the appropriate size (surface area is what counts); soldering the terminals after crimping is also recommended. 10.
9. LED/FAN Connector - Allows connection of an optional LED light bar or optional cooling fan for the amplifier. operating normally, and will be illuminated RED if the amplifier shuts down due to short circuit, DC offset, or overheating detected by onboard protection circuitry. 10.
REAR PANEL CONNECTIONS 1. Fuses - These fuses protect the amplifier against internal electrical damage and are meant to protect the amplifier only. All other power connections should be fused at the source. The D600 uses 1-40A fuse, the D800 uses 2-25A fuses. 2. (+) 12 Volt Power - Connect this terminal through a FUSE or CIRCUIT BREAKER to the positive terminal of the vehicle battery or the positive terminal of an isolated audio system battery.

PARALLEL SYNCED GAIN CONNECTIONS/SETTINGS Refer to figure 5 for wiring details. 1. Input Signal - Connect these RCA jacks as described in the Front Panel Connection section of this guide. 2. Slave/Master Switch Set the slave/master switch on the master amplifier to the MASTER position. Set the slave/master switch on the slave amplifier to the SLAVE position.
CROSSOVER SETTINGS AND GAIN ADJUSTMENT Your Directed Audio power amplifier needs to be adjusted carefully to achieve maximum performance. These are some guidelines to follow when finetuning the amplifier. Because this amplifier is only designed for subwoofer applications, the low-pass crossover is active at all times. The crossover point is adjustable to allow more precise system operation.
crossover settings the way you like. Test discs and analyzers may help with this process, but in the end it's your ears that count --listen to the music! LED TUBE INSTALLATION (OPTIONAL) This Directed Audio amplifier has been designed with a custom heat sink that can accommodate two (optional—not supplied) LED tubes. Follow the installation instructions provided with the LED tubes. Use the following cross reference chart to select the proper length LED tube for use with your Directed Audio amplifier.
