DESCRIPTION
The D3 Series Amplifiers provide a wide range of power and features that make them an excellent choice for a variety of car audio sound system configurations.
D3 Amplifiers use an unregulated power supply for good control of output power. This power supply design helps yield maximum power transfer with a minimum of heat loss.
On board noise filtration is used to keep unwanted noise from leaking into the system from the amplifier. Each D3 amplifier comes complete with thermal, short, and load protection circuits as well.
All connections and controls for the D3 Amplifiers are located on the end panels.
Plated connections ensure excellent conductivity and good looks. Easy to understand controls make setting the amplifier up correctly an easy task.

Gain Control Allows the nominal operating level of the amplifier to be set in conjunction with the level of input voltage from the source unit. The D3 amplifiers will accommodate low level (RCA) input ranging from 500 mV~5 V.
Bass Boost Acts like an equalizer with an adjustable gain fixed at 45 Hz. This adjustment gives you up to 18 dB of boost at that frequency. This can be used to compensate for lack of low-frequency response in the car audio environment.
Crossover Frequency Selection The crossover frequency is fully adjustable between
55 Hz and 550 Hz.
Crossover Mode Switch Switches crossover between off, low-pass, or high-pass.
When in the LP or HP position, a 12 dB per octave slope is implemented at the frequency selected on the Frequency Knob.
Input Mode Switch Sets the input mode of the amplifier, depending on its purpose in the system. Can be set to Stereo Mode, Bridged Mode, or Mono Mode.
Rear Channel Input Select (4 channel only) Allows channels 3 & 4 to use either set of inputs (front or rear) for signal.

SETTING THE GAIN
The best way to set the gains on any amplifier is with an oscilloscope and test tone. Using the scope will ensure the amplifier is not clipping and protect your system from being damaged from being overdriven. If you have an oscilloscope and need help using it, feel free to call DAT
Technical Support for help.
Another way is with a multi-meter and test tone. Set the multi-meter to DC voltage, play the test tone at 75% volume. Tune gains up until DC voltage is present, then back the gains back down a little.
If an oscilloscope, multi-meter, or test tone is not available, find out the output signal voltage of the head unit. Match the gain knob with that amount of voltage. It should be between 500 mV and 5 V. If it is above 5 V, the head unit has too much signal and the amp will clip even with the gain set at minimum. Turn system on and volume to 75%, if there is noticeable distortion, gains should be tuned down some.
SETTING THE CROSSOVER
Select LP or HP using the Crossover Mode Switch, select desired frequency by turning the
Frequency Knob.
SETTING THE BASS BOOST
If there is a noticeable lack of low end frequency, the bass boost can be used to raise the level of bass in the system. Turn the system on to normal listening levels and raise the bass boost until the level of bass is satisfactory.
Caution: If "popping" , "crackling" ,or any other unusual noise is heard from the system when using the bass boost, immediately turn the boost down to avoid damaging components in the system. Also, if the bass sounds "muddy" or distorted, turn the bass boost down.
TROUBLESHOOTING
Problem
No Audio Output
Solution
Low or no turn-on voltage. Check remote connections at amp and head unit.
Check remote voltage at amp with multi-meter, there should be around 12 volts when
head unit is on.
Blown Fuse. Check both main system fuse and amplifier fuse. If blown, replace with
fuse of same type and rating.
Loose Connections. Check all power and signal wires to make sure they have solid connection.
Speaker lead shorted. Check all speaker wire to make sure they are not shorted out somewhere.
Blown speakers. Check speaker impedance with multi-meter, if the woofer is blown, it will read a dead short.
Problem
Amplifier cycles on and off.
Solution
Thermal protection circuits are shutting the amplifier off. Check location of amplifier
for adequate ventilation. Check impedance at amplifier for correct load. Check
voltage at amplifier for low voltage.

Problem
Distorted audio.
Solution
Check that gains are set correctly. Inspect speakers for damaged cones or bad
voice coils.
Problem
Amplifier fuse keeps blowing.
Solution:
Check all power and signal wires for a short. Make sure power and ground wires are
correctly connected to the amp.
Problem
Whining, ticking, or any other unwanted noise present in system when engine is
running.
Solution
Amplifier may be picking up alternator or radiated noise. Make sure all signal wires
are separated from power wires. Check all signal and power wires for a sold
connection. Check all ground wires to make sure they have a solid ground.
Check alternator and/or voltage regulator for solid connections. Check battery for
adequate voltage and connection.
