Quick Installation Information
If you are a seasoned audio enthusiast and are chomping at the bit
to begin your experience with the DQDX, we oer some Quick Install
Guidelines below to help maximize your experience. Please also refer
to the system diagram examples on page 14, 15, and 16.
1. Physically mount the DQDX in a locaon that keeps it away from
beverage spills, food crumbs, and curious ngers. You will want
to select a locaon that allows you access to the top panel con-
trols.
2. The DQDX needs to be installed in the signal path between
your source unit (or as some may call it, “Your Radio”) and an
aer-market amplier(s)..
Note: If your source unit has front, rear, and subwoofer RCA Line
Level outputs, connect them to the corresponding inputs on your
DQDX. If your source unit has only front and rear inputs fear not!
Just connect these to the front and rear inputs on the DQDX and
switch the “Sub to Front” jumper to the ON posion. There is a
more detailed descripon of the jumpers located under the cov-
er in the secon tled “Under The Cover”. Changing this jumper
to ON will route the low pass signal (as dened by your crossover
selecon) to the Sub outputs of the DQDX.
3. Use RCA connecng cables to connect the RCA outputs of the
DQDX to your aer market amplier(s). If this is not obvious to
you, quickly pack up your DQDX and run to your nearest autho-
rized AudioControl dealer to have them perform the installaon.
You will thank us later.
4. Connect +12 volt power, ground and turn-on wires as needed.
Don’t forget the fuse!
----------------------------------------------- 6 -----------------------------------------------
5. Connect your amplier trigger input to the 12-volt trigger output
of the DQDX.
6. VERY IMPORTANT! Make sure the input gain control on your
aermarket amplier(s) are all the way down (usually counter
clockwise).
7. Turn on the system and level match your DQDX to your source
unit and ampliers.
8. Select the correct crossover point on your DQDX to create a Hi-
Pass for the front and rear outputs and a Low-Pass for your sub-
woofer output, if you are not using the crossover on your source
unit. We would always recommend turning the crossovers OFF
on your source unit and using the sweet crossover in the DQDX.
9. On the chassis of the DQDX, set Signal Delay Mode to Set-Up.
10. Using the ACR-3 Dash Control, adjust the signal delay between
the Le and Right channels for opmum sound.
11. Tap the ACR-3 Dash Control and adjust the signal delay between
the front and subwoofer outputs.
12. On the chassis, change Signal Delay Mode back to Normal.
13. Set the equalizaon controls for the front, rear, and subwoofer
channels. While your ears are a good reference point, we recom-
mend using an audio analyzer whenever possible. To engage the
pink noise output of the DQDX for help seng up the equalizer,
press and hold the ACR-3 remote knob down for about four
seconds. This will switch the outputs of the DQDX from music
to Pink Noise. When you are done seng up the Equalizer, you
can just press and hold the remote again for 4 seconds and it will
turn the Pink Noise output o.
14. Sit back and enjoy the sound

If you have made it to this point and you don’t have any quesons,
then “Congratulaons”! With that said we certainly encourage you to
set aside some me to grab a beverage or two and read through this
enre manual, since there is a tremendous amount of useful informa-
on. Plus we took the me to write it so it would make us feel a whole
lot beer.
We now interrupt your reading of this manual to highlight a very
important feature of all AudioControl Autosound products…
Our Bulletproof Warranty
AudioControl Autosound products
are designed and assembled at our
factory in the Pacic Northwest,
just outside of a lile town called
Seale, Washington. By nature,
our products are rather sophis-
cated so we spend a good deal of
me training our dealers and their
installaon team. We do this so you will get the best possible results
from your AudioControl components.
To reinforce this point, if you have an Authorized AudioControl
dealer install your DQDX, we will extend the normal one-year war-
ranty to a full FIVE years parts and labor. Complete details of this
warranty are listed at the end of this manual and on our website at
www.audiocontrol.com.
We now return you to your regularly scheduled reading.

A Guided Tour of the DQDX
1. RCA Line-Level Inputs: The DQDX has six RCA line-level inputs.
These inputs get their signals from the RCA outputs of your
source unit. If your source unit has front, rear, and subwoofer
RCA line-level outputs, connect them to the three sets of corre-
sponding inputs on your DQDX. If the source unit only has one
output, the Front to Sub circuitry in your DQDX selecvely routes
the Front input channels to the subwoofer channels when you
have the jumper in the appropriate posion. (See “Under The
Cover” on page 12, regarding the internal jumper posions.)
2. Input and Output Level Controls: These will allow you to adjust
the signal level from your stereo or source unit to match the
input of your aer-market ampliers. Please refer to the secon
on Level Matching on page 24 for a more detailed descripon on
how to set these correctly.
3. EqualizaonControls:To custom tune your system, the DQDX
gives you dedicated equalizaon controls for the Front, Rear, and
Subwoofer outputs. See the secon on Equalizaon Opmizaon
on page 20 for a more detailed descripon on how to set these
adjustments for opmum performance.
4. 24dB/Octave Linkwitz Riley Crossover: What is the benet of
ne tuning your system if you cannot accurately route the proper
frequencies to the proper amplier channels? The programmable
audiophile crossover in the DQDX is the same crossover as in
many other award winning AudioControl components. Know who
else gives you a 24dB Linkwitz-Riley in their EQ? Nobody! This is
also a far cry from the wimpy crossovers that nd their way into
some ampliers these days.
-----------------------------------------------10 ----------------------------------------------
5. Signal Delay Mode: This allows the user to put the DQDX into
Set-Up mode and adjust the signal delay sengs using the dash
control. See page 25 for details on seng this up.
6. Ground: Connect to a good, veried chassis ground (the baery
is the best possible locaon.) Since factory ground wires typically
have mulple devices connected to them and could cause ‘Noise’
in the audio system, we would recommend to NOT use factory
ground wires or locaons.
7. +12V Power: Connect to a good source of 12-Volt power. Be sure
to use a fused connecon that does not exceed 2 Amp. Doing so
may damage your DQDX.
8. Remote In: This is the ‘on’ and ‘o’ selector for your DQDX. Con-
nect this wire directly to your source unit 12Volt trigger wire. If
your source unit is not equipped with a 12 Volt trigger wire then
nd a reliable source in the vehicle that comes on when the key
is in the ‘On’ posion and turns o when the key is in the ‘O’
posion.
9. Remote Out: Connect the 12 Volt turn on lead for your aermar-
ket ampliers directly to this connecon and not to any other.
This is crical to eliminate any ‘clicks’ or ‘pops’ during power up
and power down cycles.
10. Maximized Indicators: These brightly colored LEDs indicate when
the signal level coming into and going out of your new DQDX
is just below clipping. When properly level matched with your
source unit these LEDs should just barely ‘icker’ occasionally
when your system is playing at its maximum volume level. Please
refer to the secon on Level Matching, page 24 for a more de-
tailed step by step process (trust us…. this one is important!)
11. Power: If you have connected all of your power wires correctly,
this LED should be bright red when your system is on and ready
to go!
