Punch PBR300x4 by Rockford Fosgate

The Rockford Fosgate Punch PBR300X4 4-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 PBR300x4

Wie funktioniert die Boosted Rail Technology im Punch PBR300x4?

The Boosted Rail Technology (BRT) in the Rockford Fosgate Punch PBR300x4 amplifier enables an extremely efficient design that operates without a switching power supply. This technology increases operational efficiency by dynamically adjusting the required voltage to provide the amplifier's rated power. This allows for smaller dimensions, which is particularly useful for applications in limited space conditions. BRT, along with a highly efficient MOSFET output stage, ensures increased power output while minimizing the overall size of the enclosure, which proves advantageous in stealth installations.

Was sind die Leistungsdaten des Rockford Fosgate Punch PBR300x4?

The Rockford Fosgate Punch PBR300x4 is a 4-channel amplifier that provides an RMS power of 75 watts per channel at an impedance of 4 ohms. The dynamic power output is 84 watts per channel, also at 4 ohms. It is a non-bridgable amplifier designed exclusively for use with 4-ohm speakers. The frequency response ranges from 20Hz to 20kHz with a deviation of +/-1dB, and the total harmonic distortion is less than 1%.

Welche Eingangsmöglichkeiten bietet der Punch PBR300x4?

The Rockford Fosgate Punch PBR300x4 features various input options. A 2-/4-channel input switch allows for different configurations. There are high-level inputs with variable DC offset sensitivity for easy adjustment of the preamp level. Additionally, two low-level RCA inputs are available. The input sensitivity is variably adjustable, ranging from 150 mV to 11 V, allowing for flexible integration into different audio systems. The BRT technology enables efficient operation and ensures optimal power matching.

Wie ist der Frequenzbereich des Punch PBR300x4 geregelt?

The frequency range of the Punch PBR300x4 amplifier extends from 20Hz to 20kHz, covering a full sound spectrum. The integrated 12dB/octave Butterworth crossover provides both high-pass and low-pass filters, each selectable at 80Hz. These filter systems help to define frequencies sharply and direct them into the appropriate range for speakers and subwoofers. This ensures optimal sound performance when playing music, while the high flexibility of the frequency setting allows for adjustments to specific needs.

Wie sicher ist die Installation des Punch PBR300x4?

The installation of the Rockford Fosgate Punch PBR300x4 requires secure electrical connections, as it operates with a supply voltage of 9 to 16 VDC and requires a recommended fuse of 50 A. The amplifier is wired via 4-pin harnesses for both front and rear channels, ensuring a secure connection of the speaker cables of 1.5mm² and the main cables of 6mm². The compact dimensions of 3.88 x 10.79 x 17.14 cm should be noted to allow for space-saving and discreet installation at the desired location.

Welche technischen Besonderheiten bietet der Punch PBR300x4 zur Klangoptimierung?

The Punch PBR300x4 offers special technical features for outstanding sound optimization. This includes the MOSFET output stage, which provides clear and powerful amplification. The variable DC offset voltage regulation in the high-level range helps to minimize interference and achieve a clean sound. Furthermore, an average efficiency of 55% is achieved, which improves energy efficiency. Optical indicators for power, protection, and amplification provide visual feedback, while the advanced Class BR circuit topology ensures a stable and reliable audio experience.

Wie inkludiere ich den Punch PBR300x4 in bestehende Audiosysteme?

The integration of the Punch PBR300x4 into an existing audio system is flexible due to the variable high-level inputs and the 2/4-channel input switch. The variable DC offset voltage regulation facilitates integration into OEM systems by adjusting the necessary voltage to minimize distortion. Due to its compact design, the amplifier fits easily into tight spaces and can be used effortlessly in motorcycles, RVs, or smaller vehicles without requiring a large installation space.

Welche Abmessungen hat der Rockford Fosgate Punch PBR300x4?

The Rockford Fosgate Punch PBR300x4 amplifier has compact dimensions of 3.88 cm in height, 10.79 cm in width, and 17.14 cm in depth. This compact design allows for a variety of installation options, especially in vehicles with limited space. Nevertheless, the optimized construction does not affect the performance or functionality of the amplifier. This format is particularly suitable for hidden and discreet installations, meeting the desire of many users for minimal visibility.

Welche Betriebsbedingungen gelten für den Punch PBR300x4?

The Punch PBR300x4 amplifier operates at a supply voltage of 9 to 16 VDC, making it compatible with most vehicle batteries. A maximum current draw of 40 A is recorded in sine wave operation, while the average current draw during music use is about 20 A at 13.8 V. The recommended fuse is 50 A, ensuring proper protection. The convection cooling ensures that the amplifier remains thermally efficient and provides consistent performance even under demanding conditions.

Warum ist der Punch PBR300x4 nicht überbrückbar?

The Punch PBR300x4 is not bridgeable, as it is specifically designed to operate with a 4-ohm load. The non-bridgeable configuration helps reduce overall complexity and increases reliability in operation. This design ensures that each of the four channels is precisely tailored to the desired power, thereby avoiding efficiency losses. The fixed 4-channel configuration provides stable output performance without the risks of potential mismatches when bridging circuits, preserving the integrity of the amplifier audio.

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!
