Six Channel Line Output Converter: The AudioControl LC7i is a six
channel active line converter which allows you to keep your factory installed
source unit in your vehicle and still dramatically improve your car audio system
performance. The LC7i accepts up to six channels of speaker-level signal from factory installed amplifiers or a source unit and
converts it to a high quality, after market low-noise, pre-amp level signal that
can be fed to amplifiers and speakers.
AccuBASS: The LC7i fixes one of the biggest letdowns of today's
factory systems, weak bass. Designed for maximum sound quality and enhanced
audio performance, the LC7i incorporates AccuBASS. This patent pending process automatically corrects for the bass roll-off that is common with many factory-installed audio systems and AudioControl's unique and exclusive
AccuBASS patent pending circuitry maintains and restores the Bass as the volume is turned up, improving the audio
Speaker Input: The speaker level inputs are compatible with
nearly any factory stereo system, even most Bose systems. There are 3 pair of
inputs that will accommodate up to 400 watts.
Channel Summing: The LC7i has the ability to sum together
multiple input channels (4 or 6) from the factory source unit into 2 channels.
This is handy when the factory system has multiple, actively crossed-over
signals sent from the OEM source unit or amplifier(s). For example, in some
vehicles there is an actively crossed-over tweeter, midrange, and woofer all in
the front of the vehicle. The LC7i lets you take all of those signals and sum
them together to get a high-quality, full-range, pre-amp signal without the use
of any additional cables or hardware.
AutoMode Inputs: When there is no signal present at the
channel 3 input, the channel 2 input automatically feeds the channel 2 and
channel 3 outputs.
Output Level: The +/- 12 dB output level allows you to
adjust the head unit's voltage to the top of your amp's input range; up to 8.5
volts RMS. Each of the three pair of RCA outputs has its own level adjustment.
Auto Turn-on: The main speaker level input has a signal
sensing circuit; the unit turns on when there's a speaker level input signal and
turns off when the signal disappears.
Ground Isolation: The power supply ground is switchable, in
case of ground loop noise. The factory position is fully isolated (typically the
best choice), but can be changed to Ground or 200Ω.
Remote Output: The +12 volt DC remote output will trigger an
amp to turn on whenever the LC7i is on. The remote's maximum current output is 1
Terminal Blocks: The power/ground/remote in/remote out
terminal and the speaker level input terminals are removable; the wiring is
attached to the block, then the block is plugged into the LC7. The terminal
blocks will accommodate wire up to 12 gauge.
Optional Remote Control: Using the optional ACR-1 wired remote (161ACR1,
sold separately) you can easily adjust the output level of channel 3 of the
AudioControl LC7i, often used for a subwoofer. The remote is designed to be dash
mounted, within reach of the driver; it can be mounted under the dash with the
supplied bracket, or the bracket can be removed and the knob and LED can be
custom mounted through the dash
