For over two decades, AudioControl has been designing and manufacturing award-winning autosound products at our factory located in the rainforests of the Pacific Northwest. During this period, countless sound-off winning contestants have chosen AudioControl products to give them the competitive edge. "Can you really win without AudioControl", was part of an article written commenting on competition winning systems. Nothing sounds better than an awesome recording played back on a kickbutt system. Unfortunately, the acoustics of your vehicle can take away from your systems performance. While AudioControl products do not change the laws of physics (although they act like they do), autosound enthusiasts have long known that AudioControl products "make good stereo sound better"
Putting the driver in perfect acoustical alignment definitely has its challenges in a vehicle. In home audio it is generally pretty 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 manufactures has supplied us with. This usually creates a whole slew if issues when you add amplifier power, new speakers, and subwoofers. This is why signal delay and equalization are so critical. Equalization helps match all your new components together so they sound great and signal delay helps all that great sound arrive at you, the driver at the same time!
Designed for maximum sound quality and enhanced audio performance, the DQDX is the latest AudioControl processor to incorporate Signal Delay. This process corrects for the varying speaker locations in the vehicle.
The AudioControl DQDX lets music enthusiasts truly "take control" of their sound and receive an amazing experience.
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 driver is close to the left side speakers and further away from the right side speakers. Thus, the sound from the left side arrives much sooner than the right side. By delaying the appropriate speakers for just a few milliseconds, the DQ-61 is able to allow the signal to arrive at the same time putting the driver in perfect acoustical alignment.
Like all of AudioControl's high performance signal processors, the DQ-61 is designed to offer maximum audio performance and control. All six output channels are equipped with highly accurate graphic equalization filters. This equalization allows for the taming of the most demanding car acoustical challenges or correction of factory radio response curves.
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. The crossover selector is exact so it completely eliminates the guess work during the installation.
The high voltage, low impedance outputs make a huge difference in how your system's amplifiers will perform. First, the 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 they 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.

Nice line driver, eq, crossover
I added this to a mid-range system with a below-par head-unit. The overall impact on sound quality was remarkable, and this product allowed me to achieve a much smoother frequency curve (using android based RTA) than I was able to achieve with my 3-eq-band head unit. Installation was relatively simple, as was setup. The maximiuzation lights are helpful, and the time-alignment knob is very nice. Cross-over seems excellent in my opinion. My one complaint is that the unit seems lacking in high frequency eq. I still have a slight peak at 4k and 12k that I have struggled to effectively flatten out. I wish I could at least move the subwoofer 125k eq band to 4-6k.

Blew after only three days of use
I loved this thing when I first hooked it up! The setup was easy. Moving the sub to the front made a huge impact. Setting up the L to R delay really made the soundstage centered in the car. The equalizer settings are amazing too: you can even equalize the various bass frequencies on the subwoofer channel. The clip protection lights are a mega convenience too. I had this for three nights and when I came out to my car in the morning: it was toast. I drove and listened to music I thought was flat only to discover the subwoofer output wasn't working. AudioControl didn't respond to my request for support for two days so I returned it and am now waiting for a (double the price) Helix DSP come in.
