High-powered car audio

sound pressure levels that  
exceed the threshold at which hearing  
loss may result.  
They may also impair a driver’s ability to

scraped body sheet metal. Do not  
use factory grounded locations,  
seat bolts, or brackets that are  
spotwelded.  
2. Disconnect the battery ground  
terminal prior to making any elec-  
trical connections.  
7. Always fuse your power connection  
within in 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 the 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 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  
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 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.  
6. The amplifier should be grounded  
with a short, heavy gauge wire  
connected directly to the car at a  
bare metal surface, preferably

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.  
crimped ring terminals of the appro-  
priate 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.  
8. This amplifier is designed to drive a  
speaker load that measures from 1  
to 8 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  
ventilation installations, an external  
cooling fan may be advisable.

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.  
The crossover frequency control needs  
to be adjusted to suit your particular  
system. For subwoofer applications,  
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.  
For mid-bass/midrange settings, try to  
keep the setting low enough to keep  
your sound stage in front of you,  
without overdriving the speaker. 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  
amplifier operation. For full-range and  
simultaneous stereo/mono bass appli-  
cations, 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 ampli-  
fier 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 distor-  
tion, slowly raise the gain of the ampli-  
fier 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.  
Note:Remember that the 1200t uses a digital gain control with a  
finite number of adjustment steps. A very small adjustment  
may not cause any audible change in level.  
The same procedure should be used for  
adjusting the amplifier when the on  
board crossover is set to LOW or HIGH,  
but you will also have to take into  
consideration the effect that gain  
adjustment has on system frequency  
response and imaging. 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!

SUBSONIC FILTER ADJUSTMENT  
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 mechan-  
ical power handling of the subwoofer.  
Depending on the type of enclosure the  
subsonic filter can increase the useable low  
frequency output by an additional 10 dB!  
Acceptable boost levels are determined by  
the type of enclosure used, wattage of the  
amplifier, and the woofer’s excursion capa-  
bility.  
To adjust this filter, place the Subsonic Filter  
switch to the IN position and turn the  
Subsonic Frequency adjustment to the  
desired frequency (15–50 Hz).  
The following guidelines should be used  
for proper set-up of the subsonic filter to  
provide optimum performance and relia-  
bility from your system.
