OWNER’S MANUAL A802 A1004 models D2205
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 High-speed MOSFET switching power supply and complimentary bi-polar outputs Stereo, mono, or simultaneous stereo/mono operation Thermal, DC offset, reverse polarity, short circuit and over/under voltage protection Programmable features controlled via ESP® serial databus and Directed's proprietary Bitwriter® tool (998T) * * The Bitwriter® unit must have version 1.906 or above to fully access the amplifier features menu.
NOTE Prior to servicing your vehicle ensure that the alarm system is disarmed. Due to the amplifier’s anti-theft feature (if enabled), amplifier operation is disabled when the main power to the amplifier is removed while the alarm is armed. The amplifier operation must then be reset. If the alarm is replaced with another ESP2 alarm system, ensure that the amplifier goes through a learn routine (using the Bitwriter®) prior to reenabling the anti-theft feature. INSTALLATION GUIDELINES 1.
page. Always use the same gauge wire for the amplifier ground that you use for the power wire. Be sure to examine the battery ground cable of the vehicle, and if necessary, upgrade it by adding an additional ground wire that is the same gauge as the amplifier's power wire. Remember, the amplifier can only deliver its rated output when it is not current limited by the power and ground supply wires. 8.
5. Line Out Switch (D2205) - three positions: sum L/R—left front and rear and right front and rear channels are summed. sub L+R—set the switch to this position when using an additional D1200 amplifier connected in Parallel mode. sub 180°—set the switch to this position when using an additional D1200 amplifier connected in External Bridge mode. 6. Gain - controls amplifier sensitivity and is used to match the input level of the amplifier to the output level of the signal source.

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 A802 uses 2-30A fuse, the A1004 uses 2-40A fuses, and the D2205 uses 3-40A 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.
FIGURE 2—AMPLIFIER CONNECTIONS REAR 1 3 2 A802 A1004 D2205 ESP ® FEATURES AND CONTROLS These amplifiers incorporate an on-board Directed ESP® Engine. In addition to allowing menu-driven parameter adjustment*, operate with security products from Directed Electronics to incorporate advanced ESP2 features. Your dealer can use a Bitwriter® with Firmware version 1.906 or later to access these parameters. 10 * Note: The ESP® features are obtained by using Bitwriter® and a 3 pin ESP® cable.
completed use a Y-cable to connect the Alarm signals to both amplifiers. Note: Prior to using the anti-theft or valet features it is recommended that the alarm be installed and its functionality verified. Please consult the install or operations guide for the appropriate alarm. For the Bitwriter® to Amp connection, the cable must have the same color sequence at both ends of the cable. For the Alarm to Amplifier, the Transmit and Receive wires must cross from one end to the other.
Default mode is UNLOCKED. 6. Valet - Selecting ENABLE allows the amplifier to monitor valet signals from the alarm system. The amplifier will not power up once remote power is removed when the Valet monitoring mode is ENABLED and the alarm system has been set into Valet mode. Note: To make use of the Anti-theft or Valet features, the amplifier must "learn" which transmitters are associated with the currently used alarm system. See item 8 below.
2. Press the up arrow 3 times, or the down arrow 7 times to reach the Learn TX IDs menu. Press 'Select' until the ON appears. 3. Press the write key twice. The ESP® status indicator should begin blinking. Note: The following should be accomplished within 20 seconds or the learn session will time out. If this occurs, the LED will stop blinking. Reconnect the Bitwriter® and press WRITE twice to re-enter the TX ID Learn mode. 4. Disconnect the Bitwriter® and connect the Amp to the alarm cable. 5.

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 FULL. If the amplifier is driving your subwoofers, set the switch to LOW, and for mid-bass/midrange output, set to HIGH.
LED TUBE INSTALLATION (OPTIONAL) This Directed Audio amplifier has been designed with a custom heat sink that can accommodate two (optional—not supplied) VARAD LED tubes. 1. Before installing the LED tubes, remove and discard the mounting feet from the VARAD LED tubes. 2. Slide each LED tube assembly into your Directed Audio amplifier heat sink. Ensure that the LEDs are facing out for optimal visibility. The wires from the LED tube assembly should be on the signal input end of the amplifier.
SUBSONIC FILTER ADJUSTMENT (D2205 ONLY) This amplifier incorporates a subsonic filter to maximize the performance of a subwoofer. The subsonic filter is a high pass filter that removes unwanted bass output at very low frequencies from the woofer. This increases the output of a subwoofer by as much as 3 dB by increasing the mechanical power handling of the subwoofer.
