Signal Delay

Because of speaker placement limitations and the seating positions in a car, it is almost always

the case that the driver of the vehicle is in an incorrect acoustic alignment. This exists because

the sound from the left side arrives at the driver of the vehicle much sooner than the sound from

the right side. By delaying the appropriate speakers for just a few milliseconds, the AudioControl

DQDX is able to allow the signals from each speaker to arrive at the same time thus putting the

driver in perfect acoustical alignment.

Equalization for Maximum Control and Performance

Like all of AudioControl’s high performance signal processors, the DQDX is designed specifically

to offer maximum audio performance and control. All 6 output channels are equipped with

seven highly accurate graphic equalization filters. This equalization allows for the taming of

even the most demanding car acoustical challenges.

24 dB / octave Linkwitz-Riley crossover

The AudioControl DQDX uses a 24 dB / octave Linkwitz-Riley

alignment crossover to separate the bass frequencies from the

midrange and high frequencies. The crossover in the DQDX

gives you a flat response without any peak or dip around

the crossover frequency. In addition, the 24dB crossover

makes the transition without the phase irregularities you

get in most other configurations. Our crossover selector is

exact so it completely eliminates the guess work during the

installation.

High Voltage Line Driver

Our high voltage, low impedance outputs make a huge

difference in how your system’s amplifiers will perform.

First, our high voltage pre-out means your amplifier can reach

full power without having to turn up the amplifier‘s input gain controls. This

means you get more volume with less noise and less distortion. At AudioControl we are all

about ‘Making Good Sound Great’ and with the built in Line Driver in the DQDX you will be

sending the best possible quality signal into your amplifiers.

Why do you need Signal Delay (or an Equalizer for that matter) Putting the driver in perfect acoustical alignment definitely has its challenges in a vehicle. In home audio it is generally easy to just move a speaker forward or backward or to the left or to the right to help make sure you hear both speakers at the same time. In a vehicle, we are typically stuck with the speaker locations that the vehicle manufacturers has supplied us with.
