VEHICLE SERVICING 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.
guide. Minimum wire gauge recommendations for the individual amplifiers are listed on the specification 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.
FRONT PANEL CONNECTIONS/CONTROLS 1. RCA Input Jacks - Accepts line level outputs from head units or signal processors at voltages between 150mV and 7.5 volts. 2. RCA Line Output Jacks - These pass through RCA jacks can be used to send the input signal to a second amplifier. 3. Slave/Master Switch - Controls whether the amplifier is a slave or master when connected in combined amplifier configurations. (Refer to the Combined Amplifiers section of this guide.) 4.

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 D1200 uses 2-30A fuses, and the D2400 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 D1200 D2400 FUSE 40A x 3 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 2.0 or later to access these parameters. * Note: The ESP® features are obtained by using Bitwriter® and a 3 pin ESP® cable.
to the other. Status indicator will not flash. Bitwriter® commands can control parameters such as Turn on Delay, Fan Control, Input Gain adjustment, and also place the amplifier into a monitoring state for commands from an ESP2 equipped alarm. - RESERVED - no function, reserved for future use. 1. Turn-On Delay - 0.75, 1.00, 1.25, 1.75, 2.25, 2.75, or 3.25 seconds. 1.75 seconds is the factory default setting. 2.
If selected while the remote power is on, the amplifier will continue playing until the remote power is turned off. To Clear Valet Mode, Disable Valet mode on the alarm, then cycle the remote power line off then on again. The amplifier will power up normally after the Turn On Delay time has expired. 7. Anti-theft - Selecting ON, allows the amplifier to monitor Arm and Disarm signals from the alarm, rendering the amp in-operable if stolen. When OFF, these signals are ignored.
unlit, but still indicates service codes or faults using the top light. 9. Learn TX IDs Default Off. Before the unit will respond to Arm/Disarm/Valet Commands from the alarm system, it needs to establish communications with this alarm system. This is established using the learn routine procedure described below. Once this procedure is performed, the unit will store this information permanently in memory.
The ESP® Status indicator flashes to indicate the current operational mode. This can be used in conjunc- Power/Protection LED tion with the Power LED to help determine the source of the problem.
SPEAKER WIRING DIAGRAMS Single subwoofer connection (top view) Two subwoofer connection (top view) NOTE: The dual + and -- sub-out terminals of the D600/D800/D1200/D2400 are paralleled internally and the combined load impedance should be taken into consideration when connecting multiple subwoofers. © 2005 Directed Electronics, Inc.
COMBINING AMPLIFIERS N OTE : Remember that the Directed ESP® amplifiers use a digital gain control with a finite number of adjustment steps. A very small adjustment may not cause any audible change in level. The Directed D1200/D2400 subwoofer amplifiers have the capability of connecting two or more amplifiers of the same power rating together in a master/slave combination for increased power with accurate level matching. They are the Parallel Synced Gain and External Synced Bridged combinations.
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.

EXTERNAL SYNCED BRIDGED CONNECTIONS/SETTINGS 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. Setting the slave/master switch on both amplifiers will automatically set the I/O RCA jack configuration according to each amplifiers slave or master designation.

MULTIPLE AMPLIFIER COMBINATIONS The Directed D1200/D2400 subwoofer amplifiers can also be used in multiples of the master/slave combinations allowing for unlimited expansion to a systems subwoofer section. To use multiples of amplifier combinations the following directions must be adhered to for best results. Amplifier configuration - Set up each master/slave amplifier combination as described for the combination type being used.
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. 22 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.
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.
