Load Selection Switch
The LC2i PRO is designed to present NO load to the
output of the factory amp, which can make some factory
amps upset and stop passing audio. The Load Selection
feature tricks the factory amp in to detecting a speaker
load so it will continue to pass audio.
20 Ω - Best suited for late model Dodge/Chrysler/Jeep/Ram/Fiat vehicles
equipped with OEM base sound system. (no separate factory amplier)
60 Ω - Best suited for late model Dodge/Chrysler/Jeep/Ram/Fiat vehicles
equipped with a separately amplied OEM “premium” sound system.
20 kΩ - Best suited for all other applications.
Setting Levels
Main Output - Fixed full range output suitable for
connecting to multi-channel ampliers for door speakers.
Use the Main Output Level knob to adjust level for this
output.
Bass Output - Variable low passed output (1000 Hz low
pass) and is suitable for connecting to a subwoofer amplier. Use the
Bass Output Level knob to adjust level for this output. Once the Bass
Output level is set for optimum signal, level can be adjusted on the y
using the included ACR-1 level control.
Maximized Light
The Maximized Light can be used to help achieve
optimal output level and will let you know if you are
getting close to clipping the output of the LC2i PRO.
With the factory system set to its maximum
undistorted volume, match the output level of the
LC2i PRO to the input maximum of your after market amplier. If the
Maximized Light turns on, the LC2i PRO output is distorting. Turn
the output level down until the Maximized Light turns o. IF THE
MAXIMIZED LIGHT NEVER TURNS ON, don’t panic. This just means the
output of the LC2i PRO is not clipping/distorting.
ACR-1 Level Control
The ACR-1 is a great way to control the Bass Output level being sent to
your subwoofer amplier. The ACR-1 ONLY controls the level of the Bass
Output and is strictly an attenuator knob. The ACR-1 will NEVER increase
the Bass Output level past where Bass Output Level knob is set.
Setting AccuBASS®
AccuBASS is a feature that restores bass
frequencies on factory systems that roll
o the bass as you increase volume.
If you can hear that the bass does not
increase as you continue to turn up the
volume on the head unit, then your
factory system is most likely rolling o bass.
There are two AccuBASS controls and a status LED used during initial
setup: AccuBASS Threshold determines when AccuBASS turns on, and
AccuBASS Level adjusts how much bass is restored. The status LED will
illuminate when AccuBASS is active.
1. Turn AccuBASS Threshold all the way down (counterclockwise)
2. Set AccuBASS Level at the 12 o’clock position
3. Play some bass-heavy music you are familiar with
4. Slowly turn up head unit volume until you start to hear bass
dropping out (roll o). Stop turning up the head unit volume.
5. Slowly turn AccuBASS Threshold to the right (clockwise) until the
status LED illuminates and you hear hear bass being restored. Stop
adjusting AccuBASS Threshold.
6. With AccuBASS Threshold set you can now adjust AccuBASS Level
to your liking.
If the sound system in your vehicle does not reduce bass output at
higher volumes, AccuBASS may be defeated, or used without the
threshold setting (on all of the time). To defeat (turn o) AccuBASS, turn
AccuBASS Threshold all the way down (counterclockwise), and turn
AccuBASS Level all the way down (counterclockwise).
To keep AccuBASS on all of the time so it does not turn on/o at a set
threshold, turn AccuBASS Threshold all the way up (clockwise). Now,
regardless of the head unit volume, AccuBASS will always be on. Adjust
AccuBASS Level to your liking.
Remote Output
Use the Remote Output (Rmt Out) to trigger on your aftermarket
amplier. When the LC2i PRO turns on (regardless of method) the
Remote Output will always be active. Do not connect more than two
ampliers to the LC2i PRO Remote Output. Connecting more than two
ampliers may damage the LC2i PRO.
