Channel Inputs - AudioControl LC7i PRO Quick Start Manual

Channel Inputs

4. Channel Inputs (1-2-3) – The LC7i PRO has six speaker-level inputs. This
is where you connect the speaker-level outputs of your factory-installed
source unit or amplifier.
If your source unit has front, rear, and subwoofer speaker-level outputs,
connect them to the three sets of inputs on the LC7i PRO. If the source
unit only has front and rear outputs, connect them to the Channel 1 and
2 Inputs and visit the Signal Bus section on page 8 if you want to route
audio to the Channel 3 outputs.
Be careful with the speaker wire polarity (+/-), so your new audio system
is not out-of-phase and sounding "wonky". If you're not sure which
speaker wires to use or the correct polarity, you have a few options: A)
find the wiring diagram for your vehicle, B) get an audio T-Harness that
is pre-wired and plugs into the factory harness, or C) have your LC7i PRO
professionally installed by an authorized AudioControl Dealer.
5. Load Select – The LC7i 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 Select 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 amplifier)
60 Ω - Best suited for late model Dodge/Chrysler/Jeep/Ram/Fiat vehicles
equipped with a separately amplified OEM "premium" sound system.
20 kΩ - Best suited for all other applications.

6. Signal Bus – The Signal Bus switch provides an easy way to combine
(sum), route or keep audio channels separate (see page 8 for more details).
Separate (Sep.) - Sep. is the default option. All audio Inputs and Outputs
are separate. For example, audio coming in on Channel 1 Inputs is only
routed to Channel 1 Outputs.
Sum/Bus - This setting allows you to combine (sum) two or three channels of
audio inputs into a single combined output (see page 8 for more details).
