planning out your system and even sketching it
out on paper. The following diagrams are just a
few of the system options:
D. 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 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 processors and amplifiers without any
clipping or that annoying hiss! The following
steps will help guide you through the process,
although at the end of the day, your ears will be
your guides!
1) Set your source units fader and balance controls
to their center positions.
2) Disconnect the output RCA connections be-
tween your DQT and the amplifier(s). . . or next
processor in line.
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) Starting with the DQT “Input Level” control,
increase or decrease the control knob until the
“Input Maximized” LED begins to flicker
steadily with the music.
5) Now adjust the output level control until the “2
volt” or “5 volt” light starts to flicker. You will
want the output voltage to match up your
amplifiers input gain levels. If you don’t know
how much this is, ASK the amplifier manufac-
turer or read the owners manual of the ampli-
fier.
6) Very Important - Set the input gains on the
amplifier(s) at minimum!
7) Double check that you performed Step #6
8) Decrease the volume control on your source
unit and re-connect the RCA’s between the DQT
and the amplifier(s).
9) Now increase the volume on your source unit
to your normal listening level. For some of you,
this may be louder than others!
10) At this point you may find yourself going back
and adjusting the “Output Level” controls on
your DQT to accommodate for the speaker
placement and efficiency.
Note After making your equalization
settings you may need to readjust your output
levels.
