Frequent questions about BSI

Wie verbessert der DD Audio BSI den Bass in einem Audiosystem?

The DD Audio BSI is a bass signal interface specifically designed to optimize the bass range. It offers variable parametric bass processing, allowing for the restoration and enhancement of weak or lost bass in the audio system. With its variable 24dB/octave subsonic and low-pass filters, the frequency range can be precisely adjusted, resulting in clearer and more powerful bass reproduction. The digital frequency adjustment is another advantage, as it allows for fine-tuning to bring the bass to the desired level. These technical features make the BSI a powerful tool for bass enhancement.

Was sind die technischen Spezifikationen der RCA-Eingänge beim BSI?

The DD Audio BSI features differential symmetrical 2-channel RCA inputs that can provide an input voltage sensitivity of 0.5 to 5 volts and 1 to 10 volts. The RCA input impedance is at least 20k. These specifications are crucial for integration into audio systems, as they ensure high compatibility with various components. Additionally, the high signal-to-noise ratio of at least 105dBA ensures clean signal transmission, which is immensely important for sound quality. The total harmonic distortion is only 0.05%, minimizing distortion. In summary, the BSI offers a high-quality connection option for various audio applications.

Welche Funktionen bietet die mitgelieferte Fernbedienung des BSI?

The included multifunction remote control of the DD Audio BSI offers easy handling and allows for remote control of the bass processing. With the remote control, you can adjust the output level of the system and control the variable parametric bass processing. It also features an output clip indicator that visually shows when the system is reaching its power limits, helping to avoid distortion. The operation via a 12V power supply with an output current of more than 500 mA makes the remote control a practical and efficient tool for operating the audio interface.

Welche Frequenzbereiche können beim BSI angepasst werden?

The DD Audio BSI offers versatile adjustment options for different frequency ranges. The frequency response of the device extends from 15Hz to 20kHz. The subsonic filter can be adjusted in the range of 15Hz to 50Hz, while the low-pass filter can process frequencies in the range of 50Hz to 500Hz - each with a slope of 24dB/octave. This extensive adjustability of the frequency ranges allows for optimal sound adaptation to individual listening habits and the acoustic conditions of the vehicle, resulting in improved sound performance.

Wie wird der DD Audio BSI im Fahrzeug installiert?

The installation of the DD Audio BSI in the vehicle is done via the symmetrical differential RCA inputs and high-level inputs and can be quickly adjusted thanks to the selectable sensitivity of the input voltage range from 2 to 20 volts (high level) and 0.5 to 5 volts (RCA). The dimensions of 155mm x 87.4mm x 27mm allow for flexible placement, for example in the dashboard or in the trunk. Exact placement depends on the specific conditions of the vehicle, but due to the compact dimensions, it can be easily implemented in almost any car.

Welche Vorteile bietet der wählbare Eingangsspannungsbereich des BSI?

The selectable input voltage range of the BSI allows for flexible adaptation of the device to various audio systems. The RCA input voltage can be selected between 0.5 to 5 volts or 1 to 10 volts, while the high-level input voltage can vary from 2 to 20 volts or 4 to 40 volts. This allows for the integration of the BSI into both factory-installed and retrofitted audio systems, regardless of their output voltage. The adjustment improves compatibility and ensures optimal signal strength and sound quality without distortion or signal loss.

Welche Rolle spielt die Ausgangs-Clip-Anzeige beim BSI?

The output clip indicator of the DD Audio BSI is a crucial feature that provides the user with visual feedback to avoid clipping. When the audio interface approaches its power limit, the indicator signals this, allowing you to make timely adjustments to prevent distortion and potential damage to the speakers. This is especially useful for maintaining sound clarity and not overloading the amplifier. Particularly at high volumes, the clip indicator ensures that the bass remains clear and undistorted.

Wie funktionieren die variable Verstärkungsanpassung und die Masseisolierung beim BSI?

The variable gain adjustment of the BSI allows for fine-tuning of the output signal to achieve the desired volume and sound fidelity. This is done via the multifunctional remote control. The selectable ground isolation reduces potential ground loops that could lead to noise by providing an appropriate ground connection. Together, these features offer flexible sound control and help create a clear and distortion-free audio experience. Especially in complex audio systems, these characteristics are crucial for flawless performance.

Was sind die Unterschiede zwischen RCA- und Hochpegel-Ein- und Ausgängen am BSI?

The DD Audio BSI offers both RCA and high-level inputs to adapt to various system requirements. RCA inputs are typically suitable for devices with a lower voltage range, while high-level inputs are used for higher voltage levels, such as those found at speaker outputs. The RCA outputs can generate voltages of over 10 volts to ensure strong performance. The high input impedance of RCA (≥ 20k) and high-level (180) ensures efficient signal transfer without sound loss. This provides flexibility in application and improves integration into various audio systems.

Welche Eigenschaften hat das Gehäuse des DD Audio BSI?

The housing of the DD Audio BSI is made of aluminum, making it both stable and lightweight, and provides efficient heat dissipation, which is crucial for protecting the internal electronics. The compact dimensions of 155mm x 87.4mm x 27mm facilitate integration into various vehicle types without taking up much space. The robust material properties of the aluminum housing also provide a resilient barrier against external influences and noise, which protects the internal electronics and keeps the sound dynamics undisturbed.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

X-10 v3 d2

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
