The setup

This GUI is designed to take you smoothly through a system set-up, and we made some
major improvements in both control and features.

Each of the 10 memory presets will store the current input source and all current parameters,
so the first step is to choose the input (

1

) you want to use for the setup. All inputs except

MAIN are 2-Ch inputs. The

Main input

can be 2-Ch, 4-Ch, or 6-Ch. (

2

), and either an aftermarket

head unit or a factory OEM stereo. If the Main input is from a factory stereo with active
crossovers you can click MIX to sum the left channels together and the right channels together
to form a single full range 2-Channel input. The 

Channel map

(

3

) for the main input will be

in default mode after you choose the input type. If you need to change the input for any
channel you can do that here, by clicking on the input you want to use for each channel and
clicking off any you do not want to use. Once your channel map is fixed you measure the
distance from where your head will be while listening, to each of the speakers (in cm) and
enter those distances in the 

Car Speakers diagram

(

4

). After the distances are entered you

can click DelayCalc and the system will calculate enter the delay for each speaker in the delay
section. After you measure the speaker locations for delays for each channel, you need to tell
the system what each speaker location is doing.
