Great Features of the DQDX
Signal Delay Operation
Because of speaker placement limitations and seating positions in a
car, the driver of the vehicle is in an incorrect acoustic alignment with the
speakers. The following steps will guide you in delaying the appropriate
speakers for just a few milliseconds, so the DQDX is able to allow the
different signals to arrive at the same time putting the driver in perfect
acoustical alignment.
1 For best performance and ease of set-up, go to our website at
www.audiocontrol.com and download the Signal Delay Set-Up App for
your Apple iPhone or iPad. It's FREE and will help take all the guess-
work out of setting up the delay. However, if you do not have access to
an iPhone or iPad, don't worry, you can easily set up the delay just by
using your own two ears.
2 After you have made all your power and ground connections, select
your crossover point on the DQDX and set your input and output levels
correctly. Turn the Signal Delay knob on the chassis all the way to the
right to go into Set-Up Mode. You will notice that when you are in Set-
Up mode the Orange light on the chassis turns on and the blue light will
blink on the ACR-3 dash remote.
3 You will need to make sure that all your delay settings are at zero.
Start with the Left to Right setting (the Red light on the remote will be
solid) and turn the knob completely CLOCKWISE until you no longer
hear any Mute Clicks. Once you have verified your Left to Right is set to
zero you want to now set your Sub to Front delay at zero. Simply push
the dash remote to switch from Left to Right to Sub to Front. At this time
the blue light will continue to blink and the red light will turn off. Again,
turn the knob CLOCKWISE until you no longer hear any Mute Clicks.
You have now set all of the delay in the DQDX to zero.
4 Now you are going to want to choose your source material to listen
to while setting the delay. Choose a song that has very strong vocals
and limited instruments (we are thinking more Adele than 9 Inch Nails
on this one). This will make it much easier to "move" the image from
down at your left knee where it currently exists, up to the center of the
dash where it needs to be. Don't laugh here but talk radio is also a great
source to set the delay because you really are able to 'visualize' the per-
son's voice moving as you adjust the delay.
