Frequent questions about Radioactive GZRA 4HD

Welche Ausgangsleistung bietet der Radioactive GZRA 4HD bei verschiedenen Widerständen?

The Radioactive GZRA 4HD amplifier from Ground Zero achieves an RMS output power of 4x 175 watts at 4 ohms. When the resistance is lowered to 2 ohms, the power increases to 4x 275 watts RMS. To achieve even more power, the amplifier can be bridged, allowing for an output power of 2x 550 watts at 4 ohms. The amplifier is also capable of delivering a maximum power of 2x 700 watts, according to the CEA-2006A standard at a distortion of 10% THD+N.

Was sind die besonderen Merkmale der SMD-Technologie im GZRA 4HD Verstärker?

The use of SMD technology in the Radioactive GZRA 4HD amplifier enables a compact and reliable circuit. SMD, or Surface-Mount Device, means that the components are mounted directly on the surface of the printed circuit board. This leads to better heat dissipation and higher shock resistance, which is particularly advantageous in mobile applications such as vehicles. The dense arrangement of the SMD components also allows for a reduction of interference in the signal path, thereby contributing to an improvement in sound quality.

Wie beeinflusst die Class D Technologie die Effizienz des Radioactive GZRA 4HD?

The Radioactive GZRA 4HD utilizes Class D technology, known for its high energy efficiency. While traditional amplifier classes A/B convert up to 50% of energy into heat, Class D achieves an efficiency of over 90%, resulting in less waste heat and power consumption. This is achieved through the rapid switching of the output stage transistors, minimizing power loss. For the user, this means cooler operation and longer battery life in the vehicle, ideal for longer listening sessions.

Was bedeutet variabler Aktivweiche mit weitem Regelbereich im Radioactive GZRA 4HD?

The Radioactive GZRA 4HD is equipped with a variable active crossover that covers a wide adjustment range. This feature allows you to optimally adapt the frequency response of the amplifier to different speaker configurations. By adjusting high-pass (HPF), low-pass (LPF), and band-pass filters (BPF), you can specifically boost or attenuate certain frequencies to create a precise and clear sound. This is especially useful when using different speaker sets or when you want to fine-tune the sound individually.

Welche Vorteile bietet der hoch effiziente Kühlkörper des Radioactive GZRA 4HD?

The highly efficient heat sink of the Radioactive GZRA 4HD is crucial for the continuous, safe operation of the amplifier. Especially under high loads, the heat sink prevents the internal components from overheating. This is achieved through a large surface area that effectively dissipates heat to the outside. Such a heat sink is particularly important in environments where it is already hot, such as in a vehicle. Through effective heat dissipation, the heat sink ensures longevity and consistent performance.

Wie unterstützt der Hochpegel-Eingang mit Auto-On Funktion die Nutzerfreundlichkeit?

The high-level input with auto-on function in the Radioactive GZRA 4HD significantly simplifies integration into existing audio systems. You can easily connect the amplifier to the speaker outputs of the factory radio without the need for an additional converter. The auto-on function offers the advantage that the amplifier is automatically activated upon signal reception. This means less manual intervention and seamless use, as you do not have to manually turn on the amplifier every time you want to start the audio system.

Ist der Radioactive GZRA 4HD kompatibel mit meinem Auto?

The compatibility of the Radioactive GZRA 4HD can be assessed particularly by considering its dimensions: With a width of 186 mm, a length of 268 mm, and a height of 52 mm, the amplifier is compact enough to be integrated into most vehicles. It is important to check the available installation space in your vehicle to ensure that the amplifier can be installed without any issues. Due to the usual dimensions of car interiors, a high level of compatibility is given.

Welche Frequenzbereiche deckt der Radioactive GZRA 4HD ab?

The Radioactive GZRA 4HD amplifier is capable of covering a wide frequency range from 10 Hz to 250 Hz. This range is ideal for audiophiles, as it encompasses both the low bass range and the mid-frequency range. The amplifier supports this with high-pass, low-pass, and band-pass filters that allow for precise frequency tuning. Whether you prefer bass-heavy music or balanced sounds, this frequency range allows you to shape the sound according to your preferences.

Welche Merkmale unterstützen die Klangqualität des Radioactive GZRA 4HD?

The sound quality of the Radioactive GZRA 4HD amplifier is supported by several technical features. This includes SMD technology, which ensures stable and noise-free signal transmission. The Class D power amplifier efficiently converts power into audio energy. Additionally, the variable active crossovers allow adjustments in the frequency response to tailor the sound to individual preferences. Together with the highly durable heat sink and generous connection options, the amplifier promotes clear and powerful audio playback.

Wie erfolgen Montage und Anschluss des Radioactive GZRA 4HD?

The installation of the Radioactive GZRA 4HD primarily requires consideration of the dimensions of 186 x 268 x 52 mm and the available space in the vehicle. The generous connection options simplify the connection to both low and high-level outputs. Be sure to choose a secure installation location that provides adequate ventilation to support heat dissipation. The connection of the connection cables should be done carefully to ensure optimal signal flow and a secure power supply, maximizing sound quality and ensuring system stability.

Super guter Subwoofer

Super Subwoofer mit extrem tiefem Bass. Die Kabel sind dick und hochwertig verarbeitet. Es gibt nichts zu beanstanden. Absolut empfehlenswert.

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 .

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!
