Under the Hood - Internal Jumpers
Here are the internal jumpers that allow you to customize the LC7i
for your particular installation.
1. Output Summing Jumpers: Many of today's better factory
stereo systems include separately-amplified and crossed-over tweet-
ers, mid-ranges, and subs. If you are going to add your own amps
and speakers to the car you will need to combine (or sum) these
separate signals into a single full-range signal for the new system.
With the LC7i, summing is a snap. The LC7i has internal jumpers
that allow you to select which input signals will be summed to the
Main outputs. When the jumper is moved to the "summed" position,
there will also be a corresponding green indicator light on the top
front of the LC7i. The shipped-from-the-factory setting is the non-
summed (separate) position.
2. Ground Isolation Selector: Occasionally alternator noise may
appear in a system because the source unit and amplifier are us-
ing different grounding schemes. To help in this situation, we have
provided alternative grounding connections. Make sure your system
is turned OFF before you move these jumpers. We ship them in the
Isolated position, which usually gives the best results.
3. GTO™: The GTO™ jumper enables/disables the Great Turn-
On (GTO™) automatic turn-on circuit. Some cars have a network
of connected systems (integrated mobile phone, assistance services,
etc) that can turn the factory amplifier on at a time when the audio
system is actually off. To prevent this from turning your system
on unexpectedly, you can bypass the GTO™ circuit by moving
the GTO™ jumper, and using an applied 12-volts at the Remote
In terminal. However, defeating the GTO™ circuit may result in
some factory features not working fully. Specifically, if the original
factory system communicated via the factory amp and speakers, it
cannot do so if the amplifier is off. We ship the LC7i with GTO™
in the "On" position.
4. AutoMode: Some cars have unusual signals on their speaker
leads and will not be easily read by the AutoMode circuit. When this
occurs you can manually bypass the AutoMode function. This is ac-
complished by moving the internal AutoMode jumper to
