Level Matching

If you have ever listened to a friend's "killer" car audio system and

heard lots of hiss, clicks or pops, then you may have experienced an im-

properly level-matched system. When a performance autosound system

is properly level matched, you should get the maximum output from your

source unit and ampliﬁers without any clipping or that annoying hiss!

The following steps will help you through the process, although at the

end of the day, your ears will be your guides!

1. Set your source unit's fader and balance controls to their center posi-

tions. If your source unit has subwoofer output (and you are using it), set

the output level at minimum.

2. Disconnect the RCA cables between your LC6i and the ampliﬁer(s).

Otherwise get some earplugs.

3. Start playing some dynamic music and set the volume on your

source unit to about 3/4 of maximum. You should not be hearing any-

thing at this point as the ampliﬁers are unplugged. If you are hearing

music, go back to step #2; if you are hearing voices go see a doctor!

4. Adjust the output level controls until the "Maximized" light starts

to ﬂicker. If the Maximized LED does not come on but you are hearing

music, fear not. The signal level from your source unit is probably not

sufﬁcient enough to trigger the LED. Do not worry, proceed on.

5. Set the input gains on the ampliﬁer(s) at minimum! This is known

as turning down your gains.

6. Double check that you performed Step #5!

7. Decrease the volume control on your source unit and re-connect the

RCA's between the LC6i and the external ampliﬁer(s).

8. Now increase the volume on your source unit to your normal listen-

ing level. For some of you, this may be louder than others!

9. At this point you may ﬁnd yourself going back and adjusting the

Output Level controls on your LC6i to balance the front, rear, and sub-

woofer sections of your system to accommodate speaker placement and

efﬁciency. Speakers on the rear deck of your car will probably sound

louder that the ones in your doors!

Dash Control (available separately)

Placement And Mounting

The dash control may be mounted under the dash using its own bracket

or through a custom hole in the dash. It should be within reach of the

driver and in a spot where the LED is plainly visible.
