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 obstruc-

tions 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. Avoid sharp metal areas when

routing cables to the amplifier, and run RCA cables away from the power cables and other potentially noisy car harnesses.

6. The amplifier should be grounded

with a short, heavy gauge wire connected directly to the car at a bare metal surface, preferably scraped body sheet metal. Do not use factory ground locations, seat bolts, or brackets that are spot welded.

7. Always fuse your power connection

within 8 to 10 inches of the battery

terminal. Use a fuse or circuit breaker rated slightly more than the on-board fuse(s) of the amplifier(s). The gauge of power wire used should take into account the total current draw of the system, and the length of wire used. IASCA and other auto sound competition organizations have charts available for this; you can also find a chart in the MECP study 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. This amplifier is designed to drive a speaker load that measures from 1 to 4 ohms (D600 2 to 4 ohms). Keep in mind that heat is the longterm enemy of automotive elec-

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. Due to the high-frequency MOSFET switching power supply, filtering the power cable is not generally required (remember that the amp can’t deliver full output if the power supply is restricted). Proper grounding of the signal source is mandatory for the amplifier to reach its performance peak. If the RCA inputs are not grounded adequately via the signal source, electrical noise from the vehicle may be picked up in the system.

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.

WWAARRNNIINNGG::

DO NOT attempt to combine amplifiers of different power ratings. These amplifier combinations work correctly only if the Master and Slave amplifiers are identical models.

Parallel Synced Gain

This combination allows the amplifiers to drive their own separate subwoofer(s) while being synced together via an inphase audio pre-amp signal from the master amplifier. Wiring connections to the amplifier subwoofer outputs in this combination should be standard in-phase configurations, creating a parallel speaker connection. (Refer to

Parallel

Synced Gain

section of this guide for amplifier and speaker connection diagrams.)

NNOOTTEE::

One master amplifier can control up to three slave amplifiers in this combination. Multiple identical master/slave combinations can be added to any given system.

External Synced Bridged

In this master/slave combination the master amplifier pre-amp controls remain active and the slave amplifier pre-amp is bypassed. This allows the master amplifier to control gain, filter, and sub-level on both amplifiers. This combination allows the amplifiers to drive common subwoofer loads while being synced together via an out-of-phase audio pre-amp signal from the master amplifier. In this subwoofer wiring configuration the master amplifier sends the positive signal to the subwoofer while the slave amplifier sends the negative signal, making an externally bridged speaker connection. (Refer to

External Synced

Bridged

section of this guide for amplifier

and speaker connection diagrams.)

NNOOTTEE::

Amplifiers in this combination can only be connected in matched pairs. Multiple matched pairs may be added to drive separate subwoofer loads in a given system.

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.



AAuuddiioo ssiiggnnaall

- Divide the head unit or processor audio signal to the master amplifiers by using RCA Y adapters. Be sure to divide them an even number of times to ensure the input level at each master amplifier is matched.



AAmmpplliiffiieerr ccoonnffiigguurraattiioonn

- Set up each master/slave amplifier combination as described for the combination type being used. (Refer to the

Parallel Synced Gain

or the

External Synced Bridged

section of this guide for amplifier and speaker connection descriptions.)

1188

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.

 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.

 Try and keep the setting low enough to prevent image smearing (you should not

be able to hear male voices from the subwoofer) but not so low as to create a gap between the subwoofer and the mid-bass/midrange speakers. It will be to your advantage to spend some extra time with this adjustment, listening to familiar music or system set-up discs to achieve the kind of musical reproduction that you prefer.

 The gain adjustment allows you to set proper signal match for clean, quiet ampli-

fier operation. Start by playing some music you are familiar with. With the gain adjustment on the amplifier in the middle of its rotation, bring up the volume on your head unit to the 3/4 volume setting or until you start to hear distortion or clipping. If you hear distortion before you reach the 3/4 volume setting of your head unit, reduce the gain setting on the amplifier and start to raise the head unit volume again. When you can listen to the music at or slightly above 3/4 on your head unit without audible distortion, slowly raise the gain of the amplifier until distortion is heard, then back off the gain until the distortion is not audible. This setting will allow you to reach full output with all but the quietest of source material, while avoiding excessive noise in the system.

 For systems using the Remote Sub Level Adjustment, increase the subwoofer gain

on the amplifier by 25% and set the Remote Sub Level knob to the center position after making all system gain and filter adjustments. This will give the Remote Sub Level Control a wider range of adjustment to the subwoofer output.

 You should take into consideration the effect that gain adjustment has on system

frequency response and staging. Again, plan on spending some time with music that you know getting the gain and 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) 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. The Black wire from the LED tube is ground and the Black/White wire from the LED tube is power.

4. Run the two wires from the tube assembly and connect them to the 4-pin LED/FAN input connector. Refer to the LED/FAN harness diagram given earlier in this manual.

NNOOTTEE::

If the optional fan IS NOT being used, it is recommended that the second LED tube be wired to this circuit. If the optional fan is being used, it is recommended that the second LED tube be wired in parallel with the first LED tube.
