VEHICLE SERVICING NOTE  
Prior to servicing  
that the alarm system is  
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  
your vehicle ensure  
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 reen-  
abling the anti-theft feature.

INSTALLATION GUIDELINES  
1. Please read this owner’s manual  
carefully before installing this ampli-  
fier.  
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.  
2. Disconnect the battery ground  
terminal prior to making any elec-  
trical connections.  
3. Check for any hazards or obstruc-  
tions such as gas tanks, fuel or  
brake lines, and wiring harnesses  
before mounting the amplifier.  
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  
4. Pick a mounting location that will  
provide adequate access and venti-  
lation 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.

guide. Minimum wire gauge recom-  
mendations for the individual ampli-  
fiers 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 neces-  
sary, upgrade it by adding an addi-  
tional 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.  
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 appro-  
priate size (surface area is what  
counts); soldering the terminals  
after crimping is also recom-  
mended.  
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.  
8. This amplifier is designed to drive a  
speaker load that measures from 1  
to 4 ohms. Keep in mind that heat  
is the long-term enemy of automo-  
tive electronics and the lower your  
speaker load, the more heat is  
generated. For low impedance  
speaker applications or restricted

the unit is armed, the unit is placed  
into a "stolen state". The ESP®  
Status indicator will blink rapidly,  
and the amplifier will not continue  
its power up sequence. Also when  
there is currently an ARM signal  
active on the bus, the amplifier  
cannot be written to by the

Note  
: Remember that the Directed ESP Engine incorporates a digital gain control with  
a finite number of adjustment steps (32). A very small adjustment may not cause  
any audible changes in output. In addition the range selected may further restrict the  
adjustment. Extremely quick, large changes may result in audible artifacts, particu-  
larly on low frequency material as the gain is changing more rapidly than the source  
electrical wave.

diagrams.)  
NOTE:  
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.  
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.  
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.)  
WARNING: 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  
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 ampli-  
fier to control gain, filter, and sub-level  
on both amplifiers.  
This combination allows the amplifiers to  
drive their own separate subwoofer(s)  
while being synced together via an in-  
phase 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  
NOTE:  
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.

NOTE:  
You MUST set the Subsonic, EQ, and other filter  
settings on the master amplifier to the same posi-

speaker terminals to any combina-  
tion of one or more subwoofers that  
results in a nominal impedance  
between 2 and 4 ohms. DO NOT  
connect loads of less than 2 ohms  
when connecting to amplifiers in  
the External Synced Bridged combi-  
nation.  
Set the slave/master switch  
on the slave amplifier to the SLAVE  
position.  
Setting the slave/master  
switch on both amplifiers will auto-  
matically set the I/O RCA jack  
configuration according to each  
amplifiers slave or master designa-  
tion.

systems subwoofer section. To use  
multiples of amplifier combinations the  
following directions must be adhered to  
for best results.  
each master/slave amplifier combi-  
nation as described for the combi-  
nation type being used. (Refer to  
the Parallel Synced Gain or the  
External Synced Bridged section of  
this guide for amplifier and speaker  
connection descriptions.)  
Audio signal  
- 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.

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 mate-  
rial, 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.  
NOTE:  
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.  
Use the following cross reference chart to select the proper length VARAD LED tube for  
use with your Directed Audio amplifier.
