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 – This screw terminal connects to
the +12V battery binding post of the vehicle. Use quality insulated
wire, 4 to 0 AWG.
3. Remote Power Input Terminal – This screw terminal connects to
the 12V remote trigger output of some head units. When the head
unit is turned on, then the LC-6.1200 will turn on. Alternatively,
this terminal will output +12V if the LC-6.1200 turns on using GTO
signal sensing. This can be used to remotely turn-on power ampli-
ers when the LC-6.1200 is awoken by the GTO.
4. Power Input Terminal Ground – This screw terminal connects to
a good ground connection on the vehicle. Use quality insulated
wire, gauge 4 to 0 AWG.
5. RCA Analog Line-Level Inputs – The line-level output from the
head unit or factory-installed radios can connect here, so the
LC-6.1200 amplier will receive the line-level audio signals. Do
not use these inputs if you are using the speaker-level inputs.
6. RCA Analog Line-Level Outputs – The line-level output can
connect to external ampliers or subwoofer ampliers.
7. Speaker-Level Inputs – The speaker-level output from ampliers
and factory installed radios can connect here. Do not use these
inputs if you are using the RCA line-level inputs.
8. Remote Control Connector – This connects to the ACR-1 remote
level control.
9. 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 mono mode.

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.
11. Protection LED – The amplier has built-in diagnostic codes to
tell you exactly what is going wrong should the amplier detect a
problem. See page 15 for a list of diagnostic codes.
12. GTO Signal Sense – In the ON position, the LC-6.1200 amplier
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. Turn this OFF if using the
remote power terminal (see item 3 above) turn on method.
13. Front High Level – Adjusts the Front High speaker-level input
levels, to achieve a nice balance in levels.
14. AccuBASS®/ACR-1 – Enables/disables the AccuBASS® circuit and
the ACR-1 remote level control for outputs 1 and 2. If enabled, the
ACR-1 controls the level of the level of the 1 and 2 outputs and
line outputs. If disabled, then it just controls the line outputs (to
a subwoofer for example). The AccuBASS® has its own controls to
work wonders on the lower bass and line outputs.
15. HP Crossover Frequency – Selects the HP crossover point to
match your speakers and system. Channel 1 and 2 outputs will
receive the frequency range above the frequency selected. Use
the crossover range switch (16) to select the range from 30 to 300
Hz, or from 500 Hz to 5 kHz. The crossover for channels 1/2 is high-
pass only.
16. Crossover Range – Use this switch to select the range of the HP
crossover frequency control (15) from 30 to 300 Hz, or from 500 Hz
to 5 kHz.
17. Mono/Stereo – Ampliers 1 and 2 can be joined in mono to pow-
er a single more powerful speaker (4 Ohm minimum).
18. Gain Control – Adjusts the overall 1 and 2 output levels.
19. AccuBASS® Threshold – Selects the level at which the AccuBASS®
will begin to work.
20. AccuBASS® Level – Adjusts the level of the AccuBASS®.
21. 1/2 and 3/4 Bus Sum – This sums the 1/2 and 3/4 inputs together.
So two inputs (L/R) can feed four outputs (2L/2R).
22. AccuBASS®/ACR-1 – Enables/disables the AccuBASS® circuit and
the ACR-1 remote level control for outputs 3 and 4. If enabled,
ACR-1 controls the level of the level of the 3 and 4 outputs and
line outputs. If disabled, then it just controls the line outputs (to
a subwoofer for example). The AccuBASS® has its own controls to
work wonders on the lower bass of the outputs and line outputs.
23. HP Crossover Frequency – Selects the HP crossover point to
match your speakers and system (if the crossover switch (24) is set
to HP). The channel 3/4 outputs will receive the frequency range
above the frequency selected. If the crossover switch is set to
bandpass, then this selects the top frequency of the band.
6
Quick Start Guide
24. Crossover Type HP/Bandpass – The crossover of channels 3/4
can be selected as a high-pass or bandpass type. For example,
bandpass is super for bi-amping your speakers, with channels 1/2
high pass for tweeters, and channels 3/4 bandpass for mid-range.
25. LP Crossover Frequency – Selects the lower frequency of the
band to match your speakers and system (only if the crossover
type switch (24) is set to bandpass). The channel 3/4 outputs will
receive the frequency range selected by the HP and LP controls.
26. Mono/Stereo – Ampliers 3 and 4 can be joined in mono to pow-
er a single more powerful speaker (4 Ohm minimum).
27. Gain Control – Adjusts the overall 3 and 4 output levels.
28. 3/4 and 5/6 Bus Sum – This sums the 3/4 and 5/6 inputs together.
So two inputs (L/R) can feed four outputs (2L/2R).
29. AccuBASS®/ACR-1 – Enables/disables the AccuBASS® circuit and
the ACR-1 remote level control for outputs 5 and 6. If enabled, the
ACR-1 controls the level of the level of the 5 and 6 outputs and
line outputs. If disabled, then it just controls the line outputs (to
a subwoofer for example). The AccuBASS® has its own controls to
work wonders on the lower bass of the outputs and line outputs.
30. Crossover Type LP/HP – The crossover of channels 5/6 can be
selected as a high-pass or low-pass type.
31. Crossover Frequency – Selects the LP or HP crossover point to
match your speakers and system. The channel 5/6 outputs will re-
ceive the frequency range above or below the frequency selected,
depending on the setting of the crossover type switch (30).
32. Mono/Stereo – Ampliers 5 and 6 can be joined in mono to pow-
er a single more powerful speaker (4 Ohm minimum).
33. Gain Control – Adjusts the overall 5 and 6 output levels.
34. LEDs:
MILC™ Source Clip LED – The MILC™ (Maximum Input Level
Control) patent-pending level-setting circuit prevents clipping
and damaging distortion. It calculates when the waveform of an
incoming audio signal on input 1 and 2 is clipping, and if it is, this
LED will fulll its prime objective and shine forth.
With this advanced feature, you are able to optimize the level of
the incoming audio signals until the Source Clip LED is just-prior
to lighting. If the LED comes on during normal operation, you
should adjust the level of the audio signals before they reach the
LC-6.1200.
Gain Maximized LEDs – These LEDs indicate when the LC-6.1200
amplier gain for channels 1/2, 3/4, and 5/6 has been maximized
for optimum performance.

AccuBASS® and ACR-1 Notes
AccuBASS®switches
The AccuBASS switches 1/2, 3/4, and 5/6, allow you to add the
AccuBASS circuit into any speaker-level output pair: 1/2, 3/4, and
5/6 respectively. So each output can have the AccuBASS active,
and its eect controlled by the settings of the AccuBASS level and
threshold controls.
The AccuBASS gets its input signal from the 1/2 inputs, via the 1/2
bus. If the bus switches are set to SUM, then the AccuBASS will
also receive signals from inputs 3/4 and/or inputs 5/6.
ACR-1 remote
The ACR-1 remote level control aects the level of the signal after
the AccuBASS circuit, and the ACR-1 only aects those channels
that have the AccuBASS switch engaged.
Line-level outputs
The 2 RCA line-level outputs always have the AccuBASS engaged,
and the level can be adjusted by the ACR-1, without setting any
switches. In this way, the line-level outputs can be directed to
an external subwoofer amplier for example, and have its level ad-
justed by the ACR-1, and the AccuBASS working its magic on the
subwoofer tones.
The long-awaited moment when “plethora” is used in a manual
The plethora of LC-6.1200 controls allows for a wide variety of in-
stallation possibilities. This quick start guide gives a few examples
of system diagrams, and includes a few notes about the control
settings for each one.
Note: The technical writer reserves the right to be wrong about things, due to the
cold medicine being the night-time sleepy stu, and not the usual day-time strength.

Quick Start Guide
Quick Start
Here are a few general steps to get your LC-6.1200 amplier up and
running:
1. Undo the +12V and Ground connections to the car battery
before making any connections to the amplier.
2. Pick a mounting location that will provide access to the controls
and connections, provide adequate ventilation, and also protect
the amplier from heat, moisture, and dirt. Make sure the ven-
tilation slots on the sides are not blocked, and that the heatsink
ns are not covered.
3. The LC-6.1200 amplier needs to be securely mounted using the
four mounting holes located in each corner.
4. Before drilling any holes, take every precaution to prevent
any damage to fuel lines, power and other electrical wir-
ing, hydraulic brake lines, and other systems, that might compro-
mise vehicle safety.
5. When making connections, designate red RCA plugs as right,
and designate white, black, or grey plugs as left. This is a good
idea for consistency.
6. Use quality interconnect cables.
7. Connect the +12V input terminal of the unit to the +12V termi-
nal of the vehicle battery, using 4 to 0 AWG.
8. Connect the Ground terminal of the unit to the chassis of the
vehicle, using the same wire gauge as the +12V power wire.
9. Connect the remote power terminal of the unit to the remote
turn-on switch of your source unit. Alternatively, you can skip
this connection and use the GTO Signal sensing.
10. Connect your audio inputs to the unit – either speaker-level or
line-level RCA… not both.
11. Run the ACR-1 remote to the front of the vehicle to adjust the
level on the y.
12. Connect your loudspeakers (2 Ohm stereo, 4 Ohm Bridged mini-
mum load).
13. When all connections are made, reconnect the vehicle battery.
14. Adjust your input source gain using the MILC Source Clip LED.
This will indicate if the incoming audio signals are clipping.
15. Set the LC-6.1200 crossovers to the frequency recommended by
the loudspeaker manufacturer.
16. Adjust the LC-6.1200 AccuBass controls to suit. The ACR-1 adjusts
the overall output level.
17. Enjoy the drive!

Power Connections
In this example, the head unit has a +12V trigger output that is
connected to the LC-6.1200’s remote input terminal. When the head
unit is turned on, it will turn on the LC-6.1200 amplier.
Use 4 to 0 AWG insulated wire for the +12V and Ground connec-
tions.
In this example, the GTO signal sense feature can be used to gently
turn on the LC-6.1200 amplier when an audio input signal is de-
tected on inputs 1 and 2. In this case, the LC-6.1200’s remote input
terminal becomes a +12V trigger out to remotely turn on a power
amplier for example.

Quick Start Guide
ACR-1 Dash Control Installation
The AudioControl ACR-1 dash control is a remote level for your
LC-6.1200 amplier. It may be mounted under the dash using its own
enclosure, or through a custom hole in the dash. The knob should
be within reach of the driver, and in a spot where the LED is plainly
visible. Disconnect the vehicle battery +12V and Ground connections
before installation.
Dash Bracket Installation: The dash control mounts with four
screws, which attach to the underside of the dashboard. Slide
under the dash and place the dash control in its mounting po-
sition, mark the best mounting holes, carefully drill pilot holes,
and secure with screws.
Custom Installation: For that custom, nished look, the dash control
can be ush-mounted directly on the dashboard (or anywhere
else). Disassemble the ACR-1 from its enclosure.
Top Lid Removal
The top lid must be removed to gain access to the controls, and then
put back on again to protect the controls from dust bunnies.
Removal Procedure
1. Locate the two screws that hold the straight edge of the lid onto
the connector side of the amplier.
2. Use the supplied hex key to loosen both screws just enough
until this edge of the lid can lift freely up just a little. (There is no
need to remove the screws all the way, in case you lose them.)
3. Slide the lid toward the heatsink ns just a tad, before further
lifting the straight edge of the lid about 2”, then disengage the
remaining two points of contact (under the wavy edge).
4. Place the lid in a safe and handy place, ready for the time when
you have nished adjusting the controls to your immense satis-
faction, and just before Chivers brings tea and sandwiches.
