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 Dual high-speed MOSFET switching power supplies and complimentary bipolar outputs. Stereo, mono, or simultaneous stereo/mono operation. Thermal, DC offset, reverse polarity and short circuit protection. Top-mounted controls easily accessed for system tuning. Continuously variable 12 dB/ octave two-way active crossover. Switchable 8 dB bass EQ function. Buffered stereo full-range RCA output jacks.
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.
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.
REAR PANEL CONNECTIONS 1. Speaker Out Terminals - Connect the speakers to these terminals. (Refer to the Speaker Connection section of this guide.) 2. Power 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. 3.
TOP PANEL CONTROLS 1. Input Gain Adjustment - Controls amplifier sensitivity and is used to match the input level of the amplifier to the output level of the signal source. is used for mid-range speakers and tweeters. LPF attenuates high frequencies and is used for subwoofers speakers. 3. Crossover Frequency Adjustment Adjusts the crossover point for the on board active crossover. 2. Crossover Selection Switch Controls the type of filter for the onboard active crossover.

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 fine-tuning the amplifier. For full-range and simultaneous stereo/mono bass applications, the crossover selection switch should be set to FLAT. If the amplifier is driving your subwoofers, set the switch to LPF, and for mid-bass/midrange output, set to HPF.
