TWO CHANNEL LINE OUTPUT CONVERTER &
LINE DRIVER WITH IMPEDANCE MATCHING
Power
As awesome as it is that the LC1i can be turned
on 3 dierent ways, you still very much need to
connect the LC1i 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 LC1i can sense when the head unit is on, not
necessarily when audio is being sent to the LC1i.
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 LC1i 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 LC1i will not turn on.
Remote Input
This is the traditional way to turn on the LC1i 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).
Quick Start
1. LC1i is active and REQUIRES CONSTANT +12V POWER
2. Pick a suitable mounting location that will provide access
to the controls and connections. Protect the LC1i from heat,
moisture, and dirt.
3. Use the integrated mounting brackets to mount the LC1i.
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
compromise vehicle safety.
5. When making connections, 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 output of your
factory head unit or amplier. Alternately, connect the Line
Level inputs to the output of your aftermarket source.
10. Adjust the input gain using the Output Level knob.
11. Connect the Output RCAs to your aftermarket amplier.
12. Enjoy the drive!
