RTA is displaying a smooth or relatively 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).
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 have probably experienced
an improperly level-matched system. When a performance autosound
system is properly level matched, you should get the maximum output
from your source unit and ampliers without any clipping or that annoy-
ing 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 or fully counter-clockwise.
2. Disconnect the RCA cables between your LC8i and the amplier(s).
Otherwise get some earplugs.
3. Start playing some relatively dynamic music and set the volume on
your source unit to about 3/4 of maximum. You should not be hearing
anything at this point. 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
icker. If the Maximized LEDs do not come on as you adjust, fear not.
The signal level from your source unit is probably low so it is not trig-
gering the LEDs.
5. Set the input gains on the amplier(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 LC8i and the external amplier(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 nd yourself going back and adjusting the
Output Level controls on your LC8i to balance the front, rear, and sub-
woofer sections of your system to accommodate speaker placement and
efciency. Speakers on the rear deck of your car will probably sound
louder that the ones in your doors!
