Owner’s Enjoyment Manual Digital Fusion™ Introduction Welcome to the world of Digital Fusion. The fusion of AudioControl’s lengthy experience in performance signal processing combined with state-of-the-art Digital Signal Processing (DSP) technology. Congratulations also on your purchase of the DQT, the world’s first thirty-band, one-third octave stereo and parametric, digital equalizer, utilizing AudioControl’s Digital Fusion technology. Whether you are a die-hard sound-off competitor or you just enjoy good music, you will definitely enjoy how great the DQT will make your performance autosound system sound. Now before you start salivating too much just thinking about the benefits of the DQT, take a few minutes to sit back, have a latte’, decaffeinated if necessary, and read through this manual. It contains lots of useful facts and information - - and besides, we spent a lot of time writing it! KEY FEATURES OF THE DQT Here are some of the cool features that are enclosed in this magical box: • 30 bands of constant-Q equalization • Dual, fully-adjustable parametric equalizers • Eight non-volatile memories • 24 bit digital signal processing • Digital Fusion technology • Balanced differential inputs FEATURES AND HIGHLIGHTS 24 bit Digital Signal Processing: AudioControl’s Digital Fusion signal processors use a special 24 bit DSP that was specially designed for equalization and other dynamics processing. In addition, matching 24 bit A/D - D/A converters are incorporated for maximum sound quality. Constant-Q equalization controls: Car interiors vary widely in size and acoustic makeup. In addition doors, kick-panels, and rear decks don’t make the best location for speaker placement causing your high performance speaker system to sound somewhat lackluster. The DQT offers thirty precise equalization controls, spread equally across the audio spectrum, at one-third Owner’s Enjoyment Manual AudioContro. octave increments for maximum control. In addition each equalization filter utilizes precise constant- Q topology, traditionally utilized only in the highest performing professional audio products. Parametric equalization controls: In addition to the thirty, one-third octave spaced controls, the DQT also offers two, fully-adjustable parametric equalization controls for each channel. With the DQT’s parametric controls, a user can select a center frequency, dial in the ideal bandwidth and apply the appropriate amount of boost or cut. The precise filtering of the DQT allows you to select bandwidths as narrow as 1/12 octave! Non-volatile memories: The DQT has the ability to allow the user to set and store eight different equalization settings in individual memory locations. Pre-Amp Line Driver: The DQT offers a high quality line driver that takes the low output voltage of a source unit and increases it up to 18dB. This allows you to drive your amplifiers to their maximum output without clipping. No hiss, clicks, or pops plus maximum sound quality. Bulletproof Warranty: The most important feature of all.
