Frequent questions about D4.75

Welche Leistung bietet der DD Audio D4.75 Verstärker im 4-Ohm-Brückenmodus?

The DD Audio D4.75 amplifier offers an impressive continuous power of 2 x 180 watts RMS in 4-ohm bridged mode, making it a powerful companion for compact audio applications. These power characteristics are ideal for applications where high audio output is required, such as in motorsport or boat audio installations. Despite its small size, the amplifier impresses with high power output and versatility to support sonically demanding applications.

Wie ist die Wasserschutzbeschichtung des D4.75 umgesetzt?

The DD Audio D4.75 amplifier features a water-protected circuit board that has been specifically designed for use in harsh environments. This protection makes the amplifier exceptionally robust, as it is effectively resistant to moisture and dust. As a result, it is not only suitable for use in motor vehicles but also perfect for motorcycles, UTVs, and marine applications, where it withstands extreme conditions and ensures long-term reliability.

Über welche Filtermöglichkeiten verfügt der DD Audio D4.75?

The DD Audio D4.75 amplifier is equipped with variable 12dB/octave filters that include both sub-sonic and low-pass filters. The sub-sonic filters cover a frequency range from 50Hz to 5kHz, while the low-pass filters also range from 50Hz to 5kHz. These adjustable parameters allow for precise frequency control to eliminate unwanted frequencies and optimally adjust the displacement desired for the speakers.

Wie hoch ist die maximale Stromaufnahme des D4.75 Verstärkers?

The DD Audio D4.75 amplifier has a maximum current draw of 40 amperes. This specified current draw is an indicator of its performance, as it ensures the need for sufficient power supply for optimal operation under full load. Especially in high-performance applications at low impedance, this current draw is crucial. The choice of power cables with a cross-section of 2 x 1.5mm² is essential for a stable and loss-free power supply.

Welche Kanal-Konfigurationen sind beim D4.75 möglich?

The DD Audio D4.75 is designed as a 4-channel amplifier that allows for different power outputs. In 4-ohm mode, it delivers 75 watts per channel, while in 2-ohm mode, it provides 90 watts per channel. The amplifier can also be bridged to output 2 x 180 watts RMS. This flexible configuration option is excellent for making individual speaker adjustments, whether in complex multi-channel sound systems or in power-driven stereo applications.

Welche Bedeutung hat der RCA-Eingang beim DD Audio D4.75?

The DD Audio D4.75 is equipped with RCA inputs that accept an input voltage of 6V to 0.2V. This wide voltage range allows for connection to various signal sources with different signal outputs. The RCA input also has a signal-to-noise ratio (S/N) of over 90dB, contributing to clear and distortion-free signal transmission. These features make the amplifier extremely adaptable to various audio sources and installations.

Welche Empfindlichkeit und Verzerrung weist der D4.75 Verstärker auf?

The DD Audio D4.75 offers an RCA input sensitivity of 0.2V to 6V, which means it can efficiently process both quiet and strong signals to transmit them to speakers. At the same time, the distortion factor is very low at less than 0.2%, ensuring remarkably clear and undistorted audio signal output. This combination provides an ideal foundation for integration into high-quality HiFi systems, where precision and purity of sound are essential.

Welche Abmessungen hat der DD Audio D4.75 und wie beeinflusst das die Installation?

With dimensions of 160 x 100 x 45 mm, the DD Audio D4.75 is designed to be extremely compact. This small size significantly facilitates installation, especially in tight spaces, such as in motorcycles or compact vehicles. Thanks to its size, it can be easily installed under seats, in glove compartments, or even in cramped boats. This flexibility in placement allows the user to integrate the unit almost invisibly without compromising performance.

Ist der DD Audio D4.75 Verstärker für den maritimen Einsatz geeignet?

The DD Audio D4.75 is ideally suited for marine applications due to its water-protected circuit board. This protective feature allows for use in environments with high humidity and potential water exposure, such as in boats or other marine vehicles. In addition to protection against moisture, the excellent workmanship ensures resistance to corrosion and environmental stressors, highlighting its usability in various environments.

Welche Bedeutung hat das MOSFET-Netzteil im D4.75 Verstärker?

The DD Audio D4.75 is equipped with a MOSFET power supply amplifier that ensures efficient power supply and low heat generation. MOSFETs are known for their ability to perform fast switching operations, making them particularly suitable for use in high-performance amplifiers. This technology also ensures that maximum power is reliably and efficiently achieved without overloading the components. The MOSFET design provides stable voltage delivery, which helps to reduce distortion.

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!
