only when the apparatus is powered o.
16. Exposure to high sound pressure levels may lead to permanent hearing
loss. Take every precaution to protect your hearing.
The lightning ash with arrowhead symbol within an equilateral
triangle is intended to alert the user to the presence of uninsulated
“dangerous voltage” within the product’s enclosure, that may be of
sucient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to
alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the
appliance.
Caution: to reduce the risk of electric shock, do
not disassemble the apparatus, other than to
remove the top panel to access the controls.
There are no user-serviceable parts inside. Refer
servicing to qualied personnel.
Recycling notice: If the time comes and this apparatus has fullled
its destiny, do not throw it out into the trash. It has to be carefully
recycled for the good of mankind, by a facility specially equipped
for the safe recycling of electronic apparatii. Please contact your
local or state recycling leaders for assistance in locating a suitable
nearby recycling facility. Or, contact us and we might be able to

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 ampliers 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 amplier 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 ampliers or subwoofer ampliers.
7. Speaker-Level Inputs – The speaker-level output from ampliers
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.

Quick Start Guide
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 amplier has built-in diagnostic codes to
tell you exactly what is going wrong should the amplier detect a
problem. See page 15 for a list of diagnostic codes.
12. GTO Signal Sense – In the ON position, the LC-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. 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 highpass 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 – Ampliers 1 and 2 can be joined in mono to power 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.
