Connection Panel Features 1 2 3 4 5 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.

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. 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. 11. Protection LED – The amplifier has built-in diagnostic codes to tell you exactly what is going wrong should the amplifier detect a problem.
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. 31. Crossover Frequency – Selects the LP or HP crossover point to match your speakers and system. The channel 5/6 outputs will receive the frequency range above or below the frequency selected, depending on the setting of the crossover type switch (30).
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 effect 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.
Quick Start Here are a few general steps to get your LC-6.1200 amplifier up and running: 1. Undo the +12V and Ground connections to the car battery before making any connections to the amplifier. 2. Pick a mounting location that will provide access to the controls and connections, provide adequate ventilation, and also protect the amplifier from heat, moisture, and dirt. Make sure the ventilation slots on the sides are not blocked, and that the heatsink fins are not covered. 3. The LC-6.

ACR-1 Dash Control Installation Top Lid Removal The AudioControl ACR-1 dash control is a remote level for your LC-6.1200 amplifier. 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.
