11. Channel Summed Indicators: Under the cover of your LC8i are
jumpers that will allow you to sum selected channels into the main (#1)
channels. This is especially useful for factory-installed systems with
actively crossed over speaker systems. These indicator LED’s let you
know which channels are being summed into the main inputs.
12. Auxiliary Input: This RCA connection can accept any two-chan-
nel audio signal that comes from secondary source devices like an iPod,
MP3 player, or Satellite radio. We are told that products like this are get-
ting popular. To activate this input, you need to tap the remote mounted
dash control and the LC8i will switch between the main inputs and this
auxiliary input. An LED indicator on the LC8i chassis will identify
which source unit is being used.
Under the Covers - Internal Jumpers
Output Summing Jumpers: Allow you to select which input sig-
nals will be summed into the Main outputs. When the jumper is in the
Summed position, there will also be a corresponding green indicator light
on the front of the LC8i. The shipped-from-the-factory setting is in the
non-summed (Separate) position.
Ground Isolation Selector: Occasionally alternator noise may ap-
pear in a system because the source unit and amplier are using different
grounding schemes. To help in this situation, we have provided alter-
native grounding connections. Make sure your system is turned OFF
before you move these jumpers.
GTO™: Some cars can turn on the factory amplier even if the source
unit is off (Alarms, Cell phones, etc). 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 ter-
minal. Using the jumper may result in some factory features not working
fully.
