TWO CHANNEL LINE OUTPUT CONVERTER
WITH ACCUBASS
®
AND IMPEDENCE MATCHING
Power
As awesome as it is that the LC2i PRO can be turned on
3 dierent ways, you still very much need to connect the
LC2i PRO to constant +12V power and ground.
Maybe one day science will invent a way to electrically
power devices via the sweet guitar solo of Jimi Hendrix,
but until then, we need +12V power and ground.
GTO Signal Sense
DC oset is a high falutin technical term that means
the LC2i PRO can sense when the head unit is on, not
necessarily when audio is being sent to the LC2i PRO. Use
GTO Signal Sense mode when your factory sound system
outputs a DC oset when it is on.
Audio Sense
When this mode is selected, the LC2i PRO will ONLY
turn on when you start playing a source from the head
unit. Whether it be the radio, CD player or streaming via
Bluetooth from a mobile device. If you turn the head unit
on, but DON’T play audio, the LC2i PRO will not turn on.
Remote Input
This is the traditional way to turn on the LC2i PRO and
gives you more control of exactly when the unit will turn
on. Most common places to connect the remote input
are from the ignition of the vehicle, fuse box, or some
other 12V source (such as a cigarette lighter).
Ground Isolation Switch
This handy switch allows the user to change how the
LC2i PRO is grounded. Sometimes when installing car
audio equipment, “ground buzz” or “alternator whine”
will creep into the audio path, wreaking havoc on your
listening experience. There are 3 positions. GND, ISO,
and 200 ohms. The unit ships from the factory in the ISO position.
GND - Power ground and audio ground are tied together.
ISO - Power ground and audio ground are separate.
200Ω - There is 200 ohms of resistance between power ground and
audio ground.
Quick Start
1. LC2i PRO is active and REQUIRES CONSTANT +12V POWER
2. Pick a suitable mounting location that will provide access to the
controls and connections. Protect the LC2i PRO from heat, moisture,
and dirt.
3. Use the integrated mounting brackets to mount the LC2i PRO.
4. Before drilling holes, take every precaution to prevent damage to
fuel lines, power and other electrical wiring, hydraulic brake lines,
and other systems that might comprimise vehicle safety.
5. When making conections, designate red RCA plugs as right, and
designate white, black, or gray plugs as left.
6. Connect the +12V input terminal of the unit to the +12V terminal on
the vehicle battery (or distribution block) using 16 to 14 AWG.
7. Connect the Ground terminal of the unit to the Ground/Negative
terminal of the battery (or distribution block) using the same gauge
wire as the +12V power wire.
8. For +12V remote turn on the Trigger Mode switch must be set to
“Rmt In”. Connect the Remote In (Rmt In) terminal of the unit to a
remote turn-on switch. Alternately, use GTO™ Signal Sense or Audio
Sense to trigger the unit on without a remote wire.
9. Connect the Speaker Level Inputs to the left and right output of
your factory head unit or amplier.
10. Run the ACR-1 remote wire to the front of your vehicle.
11. Adjust the input gain using the Main and Bass Output Level knobs.
12. Connect the Main and/or Bass Output RCAs to your aftermarket
amplier.
13. Adjust AccuBASS using the AccuBASS Threshold and Level knobs.
14. Enjoy the drive!
