Audio Control DQDX Digital signal processor

An automobile poses some unique challenges when it comes to getting well-tuned, perfectly aligned sound. Road noise and poor speaker placement create problems that require equalization, your subwoofer needs to be tuned to your vehicle, and the sound from the left speakers reaches the driver before sound from the right speakers, making it difficult to obtain a clear stereo image. AudioControl designed the DQDX processor to solve these problems and more.

Time alignment

The DQDX allows you to delay the signal from the appropriate speakers so the sound from all speakers reaches the driver at the same time, creating a clear stereo image. 10ms of delay is available for L/R alignment, and 35ms for front/sub alignment, allowing you to fine-tune the speaker response to the driver’s position.

Ins and outs

The DQDX includes six input and output channels, arranged in pairs for front, rear, and sub. Each input pair features a seven-band graphic EQ to help solve tonal problems. The outputs use a built-in line driver with a maximum output of 7.5Vrms to drive your amplifier to full power without having to crank the amp’s input gain control. The result? More volume with less noise and distortion.

Even more control

The AudioControl DQDX features a 24 dB/octave Linkwitz-Riley alignment crossover. This sophisticated crossover offers a flat response without any peak or dip around the crossover frequency and avoids the phase irregularities of lesser crossovers. You can select from six crossover frequencies ranging from 50 to 500 Hz, or a Defeat setting that turns the crossover off.
