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.
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 corresponding inputs on your DQDX. If the source unit only has one output, the Front to Sub circuitry in your DQDX selectively routes the Front input channels to the subwoofer channels when you have the jumper in the appropriate position.
When it comes to music, everyone has his or her own particular taste. Some people want pounding bass and crisp, blood curdling highs. Others may prefer a “flat” response (whatever the heck that is). At the end of the day, most people just want their system to sound balanced and “just like it did in the store” or similar to their buddy’s car. The following equalization guidelines should help you achieve your own personal audio nirvana.
What is the benefit of fine tuning your system if you cannot accurately route the proper frequencies to the proper amplifier 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 find their way into some amplifiers these days.
The PFM (Programmable Frequency Match) Filter controls the cutoff frequency of the subwoofer output. The PFM is the bottom limit for the low pass output and will help protect your speakers from a symptom commonly known as “Speaker Explodus”.
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.
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 and amplifiers without any clipping or annoying hiss. The following steps will help guide you through the process!
The DQDX is equipped with AudioControl’s unique Front to Sub circuit input that allows for the Front input signal to feed the Subwoofer outputs, when you do not have a Subwoofer input signal available. This allows your DQDX to accept front and rear inputs channels and give you Front, Rear, and Subwoofer output channels.
The ACR-3 is a multi-function remote that used for making the initial signal delay adjustments in the Set-Up mode and then providing level control over the Subwoofer output in the Normal mode. This allows you to balance the bass level with the rest of the system and then increase or decrease as needed. An additional feature of the ACR-3 dash remote is that it allows the signal processing of the DQDX (equalization and signal delay) to be switched in and out of the audio circuit. That means that you can hear the system with and without the processing to hear the difference that the tuning makes in the sound of your system.
