Frequent questions about GZPA 2SQ

Was zeichnet den GZPA 2SQ High-End Verstärker aus?

The GZPA 2SQ from Ground Zero is a 2-channel high-end amplifier that meets audiophile standards. It uses MOSFET technology, which stands for high efficiency and precise sound. A special feature is the variable active crossover with bypass function, allowing for flexible sound adjustments. The variable BIAS setting provides individual sound control, while the phase adjustment allows for additional fine-tuning. The heat sink is not only functionally efficient but also aesthetically pleasing with a illuminated Ground Zero logo. It supports high resolution audio and is specifically designed for SQ Class AB amplifiers.

Wie hoch ist die Leistung des Ground Zero GZPA 2SQ?

The performance of the GZPA 2SQ from Ground Zero is impressively flexible and suitable for various applications. At a load of 4 ohms, the amplifier delivers a power of 2 x 175 WRMS, which is ideal for many speaker configurations. If you reduce the impedance to 2 ohms, the power increases to 2 x 315 WRMS, enough to drive even demanding speakers. At 1 ohm, the amplifier provides 2 x 500 WRMS, which offers the optimum for extreme scenarios and maximum power utilization.

Welche Frequenzbereiche deckt der GZPA 2SQ ab?

The frequency response of the Ground Zero GZPA 2SQ is wide-ranging, spanning from 10 Hz to 50 kHz. This range allows for very precise reproduction of deep bass to the finest highs, which is particularly important for high-quality audio sources. The ability to cover such a wide frequency range gives this amplifier an advantage, as it is suitable for both high-resolution audio and conventional audio formats. Thus, it ensures that you do not miss any sonic details.

Was ist das Besondere an der MOSFET Technologie des GZPA 2SQ?

The integrated MOSFET technology in the GZPA 2SQ stands for Metal-Oxide-Semiconductor Field-Effect Transistor and is characterized by high efficiency and sound accuracy. MOSFET amplifiers offer the advantage of lower distortion and better thermal stability, which ensures clean and clear sound. This technology allows the amplifier to provide high power reserves while minimizing power loss. In a high-end device like the GZPA 2SQ, this is crucial for achieving a pure, audiophile sound.

Welche Funktion hat die Aktivweiche im GZPA 2SQ?

The active crossover in the GZPA 2SQ allows for precise separation and assignment of frequency ranges to different types of speakers. With the variable crossover, you can influence the transmission path of the audio signals in several parameters, which is optimally tailored to your individual listening preferences. A bypass function is also available, leaving the original signal path unaffected. This is particularly useful when you want to use external processors or crossovers and ensures maximum flexibility in sound design.

Wie beeinflusst die BIAS-Einstellung den Klang des GZPA 2SQ?

The BIAS setting in an amplifier like the GZPA 2SQ determines the quiescent current of the transistors and thus influences the dynamic properties of the sound. By adjusting the BIAS, the sound character can be changed from cool and analytical to warm and musical. Experienced users take advantage of this adjustment option to tailor the sound precisely to the desired playback environment and personal preferences. By varying the BIAS settings, different sound facets can be highlighted, making the GZPA 2SQ an extremely flexible amplifier.

Welche Maße hat der Ground Zero GZPA 2SQ Verstärker?

The dimensions of the GZPA 2SQ amplifier from Ground Zero are 222 mm in width, 420 mm in length, and 60.5 mm in height. These compact measurements allow the amplifier to be integrated into a variety of vehicles without taking up much space. When installing, you should ensure that sufficient air circulation for cooling is possible, although the built-in efficient heat sink already handles a large part of the heat dissipation. The solid construction and modern aesthetics also facilitate the harmonious integration into your vehicle.

Wie integriert sich der GZPA 2SQ in bestehende Car-Audio Systeme?

The GZPA 2SQ from Ground Zero can be easily integrated into existing car audio systems thanks to its solid and versatile connection options. The use of high-quality connection terminals ensures stable signal transmission. The amplifier is also suitable for high-resolution audio, making it ideal for existing systems that also have high demands on audio quality. An advantage is the phase adjustment, which allows the GZPA 2SQ to be optimally adapted to different speaker positions within the car.

Wie wird der Ground Zero GZPA 2SQ im Auto installiert?

The installation of the GZPA 2SQ amplifier requires some considerations regarding placement and connections. Make sure to take into account the dimensions of 222 x 420 x 60.5 mm to securely accommodate the amplifier. The solid connection options allow for smooth integration into your existing audio system. It is important to make all connections correctly and possibly consider the support of a professional to fully utilize the sound potential. Ensure adequate ventilation to allow the efficient heat sink to work optimally.

Mit welchen Automarken kann der GZPA 2SQ Verstärker kombiniert werden?

The Ground Zero GZPA 2SQ amplifier is brand-independent and can basically be combined with any car brand, as long as the dimensions and connection options fit. It is important that there is enough space for installation to accommodate the dimensions of 222 x 420 x 60.5 mm. The amplifier can be used in cars, SUVs, and other types of vehicles, with the versatile application possibilities and high flexibility in sound adjustment ensuring that an appealing sound experience can be achieved regardless of the brand and model.

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 .

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!
