Punch PBR300x2 by Rockford Fosgate

The Rockford Fosgate Punch PBR300X2 2-channel amplifier uses Rockford Fosgate's patented BRT (Boosted Rail Technology) for an extremely efficient design that does not require a switching power supply to generate the rated power. This allows the housing to be much smaller than that of conventional amplifiers. The BRT also features a variable high-level DC offset turn-on circuit for easy installation in any OEM system. It is ideal for smaller stealth installations as well as for motorcycles and RVs.

Frequent questions about Punch PBR300x2

Was zeichnet den Rockford Fosgate Punch PBR300x2 in Bezug auf seine Energieeffizienz aus?

The Punch PBR300x2 relies on Rockford Fosgate's patented Boosted Rail Technology (BRT) to achieve high energy efficiency. The omission of a traditional switching power supply not only allows for a more compact design—the amplifier's housing is significantly smaller than that of conventional models—but also enables efficient operation. The average efficiency is around 68%, which is remarkable for a product of this type. Thus, this 2-channel amplifier is ideal for applications where space is limited, such as in motorcycles or RVs.

Wie hoch ist die Leistung des Punch PBR300x2 im Stereo- und Brückbetrieb?

The Punch PBR300x2 from Rockford Fosgate delivers an RMS power of 100 watts per channel at 4 ohms and 150 watts per channel at 2 ohms in 2-channel mode. When the amplifier is used in bridged mode, it reaches a power of 300 watts at 4 ohms. The dynamic power is 114 watts per channel at 4 ohms, 160 watts at 2 ohms, and in bridged mode, it is 387 watts. These power spectra allow for versatile applications and adaptation to different requirement profiles in audio installations.

Welche Frequenzweichenfunktionen bietet der Punch PBR300x2?

The Punch PBR300x2 is equipped with a comprehensive crossover control. The integrated 12dB/octave Butterworth crossover offers both high-pass and low-pass filters that can be adjusted in the range of 50Hz to 500Hz. This flexible frequency adjustment allows the amplifier to be optimally tuned to the speakers used and their specific requirements. This way, the sound can be precisely controlled and the performance accurately adjusted to ensure the best possible audio quality.

Welche Eingangssignale kann der Punch PBR300x2 verarbeiten?

The Rockford Fosgate Punch PBR300x2 can process both high-level and low-level input signals. Thanks to the variable input sensitivity between 150 mV and 11 V and the use of a 4-pin wiring harness for signal input, high flexibility in integrating into various audio systems is ensured. This facilitates integration into existing systems, including those based on OEM technology, without the need for additional adapters or complex installation methods.

Wie gestaltet sich die Installation des Punch PBR300x2 aufgrund seiner Abmessungen?

The compact design of the Punch PBR300x2, with dimensions of 3.90 x 10.8 x 17.2 cm, makes installation extremely flexible even in limited spaces. These features make the amplifier ideal for stealth installations, where it can be discreetly and space-savingly accommodated. Additionally, it is perfectly suited for applications in motorcycles or RVs, as there is often little space for extensive audio systems. With its small size, it can be hidden behind panels or under seats and integrates seamlessly into many installation scenarios.

Welche Schutzvorrichtungen besitzt der Punch PBR300x2?

The Punch PBR300x2 from Rockford Fosgate features visual indicators for power and protection, allowing for a quick and reliable check of the operational status. These indicators provide assurance that the amplifier is functioning correctly or signal appropriate warnings in the event of malfunctions or overloads. The built-in protection circuit ensures a safe operating environment, protecting the amplifier from overheating or malfunctions, which is especially important when used in demanding or frequently changing conditions.

Wie wird die Einschaltung des Verstärkers beim Punch PBR300x2 gesteuert?

The Rockford Fosgate Punch PBR300x2 features a state-of-the-art turn-on method through a variable high-level DC offset turn-on. This technology allows for seamless and efficient integration into any OEM system by activating the amplifier as soon as an audio signal is detected. The DC offset threshold can be set in the range of 4 to 6 volts. This automation significantly reduces installation effort, as no additional control cables or triggers are needed to activate the amplifier.

Welche Kühlmechanismen nutzt der Punch PBR300x2?

The Punch PBR300x2 relies on a convection-based cooling system that operates without active fans. This passive cooling design utilizes natural air currents for heat dissipation, which not only reduces the size of the amplifier but also lowers the risk of mechanical failures due to fan damage. Combined with energy-efficient BRT technology, the cooling concept ensures that the amplifier operates reliably even under heavy load without overheating. This feature is particularly advantageous in tight installation situations.

Wie beeinflusst die Klasse-BR-Topologie die Leistung des Punch PBR300x2?

The Punch PBR300x2 uses Class-BR topology, an evolution of the classic amplifier classes, to provide premium audio quality with high efficiency and low space consumption. This special circuit topology optimizes the amplifier's power consumption and allows for more power to be gained from a smaller enclosure. In conjunction with Boosted Rail Technology, outstanding clarity and dynamics in audio output are achieved while keeping heat generation low. This is ideal for users who do not want to compromise on powerful sound despite smaller installations.

Wie wirkt sich die Nutzung des optionalen Remote Punch EQ auf den Klang aus?

With the optional Remote Punch EQ, available for the Punch PBR300x2, you have the ability to boost the bass range at 45 Hz from 0 dB to +18 dB. This feature allows for personalized sound tuning that is tailored to individual taste and specific audio environments. The remote EQ gives you the flexibility to modify the bass playback at any time and make adjustments, for example, if you have a preference for bass-heavy music styles or want to adapt the sound profile to different rooms and acoustics. This enables an even more dynamic and detailed audio playback.

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!
