AudioControl LC6i Owner's Manual

 Pre-Amp Outputs

Connect good quality RCA connectors from these outputs to the inputs 

of your ampliers.  While we won’t get into the discussion as to whether 
plutonium cables sound better than un-obtainium cables we will tell you 
that well-constructed cables are less problematic in rugged environment 
like your car system.

Summing The Outputs

Under the cover are connection jumpers that allow the Main outputs 

of the LC6i to receive signals from the inputs of Channel pairs 2 and 3. 
These jumpers allow you to select which input signals will be summed 
into the Main output.  When one of the jumpers is in the Summed posi-
tion, the corresponding green indicator light on the front of the LC6i 
will be lighted. The shipped-from-the-factory setting is in the Separate 
position. 

When you have summed several channels together, you will want to 

make sure the output levels are providing a balanced frequency response.  
A simple technique involves using a pink noise cd and a real time audio 
analyzer (AudioControl happens to make a great one!)

1) Perform all of the steps necessary to install your LC6i.
2) Connect the Main Outputs from your LC6i to the audio input on 

your real time analyzer. “Yes”, your ampliers will be disconnected from 
the LC6i at this time.

3) Start playing pink noise on your cd player and raise the volume level 

until signal is displayed on your real time audio analyzer (RTA).

4) Adjust the LC6i input level controls for each pair of channels until 

your RTA is displaying a smooth or at response curve.

5)  If you wish to make any additional frequency response adjustments 

you may want consider adding an equalizer to your system (we happen to 
know someone who makes some really good ones - www.audiocontrol.
com).
