Frequently Asked Questions about DQDX

What inputs and outputs does the DQDX Audiocontrol DSP offer?

The DQDX Audiocontrol DSP features three preamplifier inputs covering six channels, with an input impedance of 20kΩ. On the output side, it also provides three preamplifier outputs for six channels, capable of producing a maximum output level of 7.5 Vrms. The output impedance is 150Ω. This configuration allows for connecting and controlling a variety of audio systems, which is particularly beneficial for complex vehicle installations. Additionally, you can work with the output gain of ±12dB to adjust the signal for different amplifier configurations.

How does the signal delay work in the DQDX Audiocontrol DSP?

The DQDX Audiocontrol DSP is equipped with a user-friendly signal delay that controls the acoustic alignment between left and right channels as well as between front and subwoofer channels. The maximum signal delay between left and right channels is 10ms, while the delay between front and subwoofer channels can be set up to 35ms. These delay functions allow for compensating time differences in complex audio installations. Especially when you want to optimally place your speakers, this helps create the ideal listening environment.

What equalizer options does the DQDX Audiocontrol DSP offer?

The DQDX Audiocontrol DSP features individual equalizer controls for front, rear, and subwoofer channels to enable precise system tuning. The frequencies for the front and rear channels cover ranges from 125Hz to 8kHz, while the subwoofer can be adjusted between 31.5Hz and 125Hz. This allows for detailed adjustments to specific acoustic requirements and preferences. A perfectly tuned audio output is thus ensured. An integrated pink noise generator also assists with easy signal delay and equalizer settings.

What functions does the Crossover in the DQDX offer?

The electronic Crossover in the DQDX Audiocontrol is fully adjustable and is based on the Linkwitz-Riley type with 24 dB/octave. It offers a flexible crossover frequency of 50Hz to 500Hz, which can be tailored to the specific requirements of your audio setup. The PFM (Program Frequency Match) Subsonic Filter complements these features by filtering out unwanted low frequencies at either 20Hz or 30Hz. This helps to improve overall sound quality and protect the speakers by minimizing unwanted frequencies.

How does the DQDX Audiocontrol DSP work with the ACR-3 Dash Control Remote?

The DQDX Audiocontrol is complemented by the ACR-3 Dash Control Remote, which allows control of the Subwoofer level and bypassing the signal processing. This remote provides you with quick adjustments while driving, without needing to access the device directly. This is especially useful in situations where you want to change the bass level spontaneously. Additionally, the remote input offers a connection option for further control options that make your audio experience even more comfortable.

How should the DQDX Audiocontrol DSP be installed in the car?

The DQDX should be installed in a well-ventilated location with sufficient space for secure cable connections, due to its dimensions of 23.5 x 14.6 x 3.1cm. Ensure that the position is easily accessible for adjustments and protected from excessive heat or moisture. The electronic circuit is robust, but as with any technical installation, a flat, secure mounting without mechanical stress is essential. It is also important to correctly wire the RCA line-level inputs and outputs to optimally control the sound.

What power supply does the DQDX Audiocontrol require?

The DQDX Audiocontrol DSP is based on a high headroom PWM circuit and requires a current draw of 350mA. A recommended fuse of 2A ensures stable operation and avoids unwanted electrical spikes. These technical details are essential for integrating the DSP into existing vehicle wiring and ensuring its efficiency. Additionally, the 12VDC Remote Out provides a reliable connection, ensuring that the Amplifier is always correctly activated as soon as the device is turned on.

How does the total harmonic distortion of the DQDX affect the sound?

The DQDX Audiocontrol DSP has a total harmonic distortion of only 0.01%. This means that the original audio signal path remains virtually unchanged, ensuring the highest sound fidelity. This is crucial, especially at high volumes, to minimize distortion and unwanted background noise. The low distortion also helps maintain a clear, detailed sound across the entire frequency range, benefiting even the most demanding audio enthusiasts.

What app support does the DQDX Audiocontrol DSP offer?

The DQDX Audiocontrol offers support through the free iOS Mobile Tools app, which is compatible with the DQ-61 Delay module. This app allows you to conveniently make adjustments via a mobile device, which is particularly advantageous in complex setups or for quick adjustments. The intuitive user interface ensures that you have access to all important audio parameters. This way, you can comfortably adjust sound profiles and make real-time changes without the need for additional hardware.

What is the weight and dimensions of the DQDX Audiocontrol DSP?

The DQDX Audiocontrol DSP is relatively compact with dimensions of 23.5 x 14.6 x 3.1cm and weighs 1.4kg. These features make it versatile, as installation can be easier in various locations within the vehicle. The handy size contrasts pleasantly with the device's performance, ensuring that neither space constraints nor excessive strain on mounting points should be an issue. This is especially important when space in the car is limited and efficiency in installation is required.
