1. Fuses 40A – Replace these fuses only with the exact same style
and Ampere rating. Disconnect 12V power before changing or
inspecting the fuses.
2. Power Input Terminal +12V – The left screw terminal connects
to the +12V battery binding post of the vehicle. Use good quality
insulated wire, between 4 and 0 gauge.
Power Input Terminal Ground – The right screw terminal con-
nects to a good ground connection on the vehicle. Use good quality insulated wire, between 4 and 0 gauge.
Remote Power Input Terminal – The middle screw terminal
connects to the 12V remote trigger output of some head units.
When the head unit is turned on, then the D-6.1200 will turn on.
Alternatively, you can use the GTO™ feature of the D-6.1200 so it
will turn on when an audio signal is detected at the speaker-level
or line-level inputs of channels 1-2 (front).

3. RCA Analog Line-Level Inputs – The line-level output from the
head unit or factory-installed radios can connect here, so the
D-6.1200 will receive the line-level audio signals.
4. RCA Analog Line-Level Outputs – These line-level analog outputs from the D-6.1200 connect to the line-level inputs of your
power ampliers and other equipment. The matrix capabilities of
the D-6.1200 allow you to pick and choose the outputs from any
combination of inputs, add crossovers and EQ as required.
5. Speaker-Level Inputs – The speaker-level output from ampliers
and factory installed radios can connect here, so the D-6.1200 will
receive the audio signals this way and do its thing. Make sure that
you follow the plus and minus polarity markings on the D-6.1200
and match it to the polarity of the speaker wiring. Speaker-level
Inputs 1-2 have the GTO™ (great turn on) signal-sense circuit that
will awaken the D-6.1200 when an input signal is present.

6. USB Micro Connector – This connects to your computer’s USB A
port to congure the D-6.1200 with the control software.
7. Remote Control Connector – This connects to the optional ACR3 remote level control using a standard telephone cord.
8. Speaker-Level Output Terminals – These screw terminals
connect with speaker wire to your loudspeakers. Make sure that
the average combined speaker impedance does not dip below 2
Ohms, or 4 Ohms in Bridged mode. Outputs 1 and 2 can be combined in Bridge mode to power a single speaker. Use the 1+ and
2- terminals only. Outputs 3/4 and/or 5/6 can also be combined in
bridge mode, use the 3+/4- and/or 5+/6-terminals only.
9. Option Port – This port allows you to connect our optional
Bluetooth adapter, so you can stream audio into channels 7 and 8
from your Bluetooth-enabled devices. Or setup and control your
D-6.1200 with the DM Smart app. Further details will be available
when this accessory and others become available.
10. Power LED – If you have connected your battery power, vehicle
ground, and turn-on lead (or GTO™ signal sensing) correctly, then
this light should be GREEN to indicate the power is ON. An internal blue glow will also emanate from the heatsink area to indicate
that the power is ON. There are times when this blue glow will
ash, such as during power-up, and when the protection circuits
have detected a problem. See the table below.
11. Protection LED – The D-6.1200 amplier has built in diagnostic
codes to tell you exactly what is going wrong should the amplier
detect a problem. Below is a list of diagnostic codes to help you.
If the protection LED should come on, read the red codes quickly
before turning o the system and investigating. Note that the
blue power codes mentioned in the table are for the internal blue
glow from behind the heatsink area, and not the power LED which
is green. If there is problem with the unit, the sensing circuit will
shut down the unit to protect itself, and this protection LED will
come on. For example, this might happen if the temperature within the unit is too high. Check there is good ventilation around the
unit, and that the speaker wires are not short circuiting, and check
that you are not running too low of a speaker impedance.

12. Communications LED – This LED turns on when there is USB
activity between the D-6.1200 and your computer during set up.
13. GTO™ Signal Sense – In the ON position, the D-6.1200 amplier
will turn on gracefully when it detects an incoming audio signal
on inputs 1 and 2, and it will turn o after a period of time when
the audio signal fades away to silence. In some situations, factory
installed audio systems may turn on or “wake up” due to convenience features like door chimes, alarms, and cell phone signals
that trigger the source unit in the vehicle to come on. To prevent
these from turning your audio system on unexpectedly, you can
bypass the GTO™ circuit by moving the GTO™ switch to the OFF
position and use a switched 12-volt signal connected to the Remote In terminal instead.
14. MILC™ Source Clip LED – The MILC™ (Maximum Input Level
Control) patent-pending level-setting circuit (on inputs 1-2 only)
prevents clipping and damaging distortion. It calculates when the
waveform of an incoming audio signal is clipping, and if it is, this
LED will fulll its destiny and shine forth.
16
With this advanced feature, you are able to optimize the level of
the incoming audio signal until the Source Clip LED is just about
to come on. If the LED comes on during normal operation, you
should adjust the level of the audio signals before they reach the
D-6.1200.
15. Maximized Input LEDs – These LEDs illuminate when a maximum audio signal is present on any of the analog audio inputs.
During power-up, these LEDs and the output LEDs will turn on
momentarily, one after the other. Turn down the levels if these
LEDs are on a lot.
16. Maximized Output LEDs – These LEDs illuminate when there is
maximum signal present on any of the analog audio outputs. Turn
down the output levels if these LEDs are on a lot.
