The PBR300X4 is a full-range 4-channel amplifier designed for stereo front/rear systems that requires little space. Great for motorcycles and recreational vehicles. Rockford's Boosted Rail Technology provides an ultra efficient-design generating 300 Watts of power, along using the amplifier also boasts a variable hi-level DC offset turn-on circuit for easy installation into any OEM system. Rockford Fosgate Punch Series Amplification
For over 25 years, Punch amplifiers have set the normal in the vehicle audio amplifier industry and they continue to total so today. It's the reason that they have turn out to be the most popular amplifiers in the world. Each and every from the Punch family amplifiers reproduce sonic perfection along with impressive energy in a compact chassis.
Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. Discrete Surface Mount These recommendations mean your amplifier's output energy ratings are REAL POWER numbers, not inflated marketing ratings.
DSM--An industry-leading manufacturing process, DSM utilizes high-speed robotics, high-quality 1% tight-tolerance parts and big board traces. Dynamic Thermal Management These superior components are used by aerospace, automotive, and cellular manufacturers. This lower tolerance improves the effectiveness of the circuit, decreases cross-talk from other discrete components and lowers operating temperature. The discrete components are laser etched to meet a certain value and an incredibly low tolerance.
Heat is usually inefficiently dissipated across a heatsink causing"hot spots ". Reducing distortion for better sound quality. Maximizing potential of all components. Rising efficiency to create more power. This impacts crucial design goals, which are:Keeping internal components cool.
Rockford Fosgate engineers have developed an award winning cooling design called DTM. MEHSA3 This patent pending design seamlessly manages the output of power supply temperatures, while evenly distributing the excess heat across the entire amplifier.
MEHSA3 (Maximum Efficiency Heat Sink Application--gen. This strategy combined with our optimized heatsink designs, DSM (Discrete Surface Mount) technology and MOSFET devices, allows Rockford Fosgate to squeeze more watts per cubic inch from every output device too as provide consistent thermal stability. A multi-layer insulated metal substrate operating with minimal thermal resistance spreads heat both downward and outward to speedily dissipate heat from each device across the heatsink. 3) is really a proprietary process that yields up to five times better heat transfer than traditional FET mounting techniques, utilizing the exact really same components. The higher energy handling outcomes in a 20% reduction in thermal impedance. The 3rd generation creates a dielectric layer amongst the ceramic topside and also the aluminum base that retains all of the electrical isolation and capacitive coupling of the original MEHSA material increasing it's thermal conductivity.
In the early 70's, Jim Fosgate studied the acoustical properties of automobiles. Utilizing a real-time analyzer and pink noise, he would graph out the acoustical characteristics of each vehicle he tested. Jim discovered three difficulties that had been typical to all cars:A midbass hump between 100-275HzA steep roll-off of high frequencies from 2k Hz up to 20k HzReduced bass response beneath 50Hz
The Punch EQ on-board equalization circuit helps correct for these acoustical deficiencies within the listening environment. When set to All Pass (AP) operation, both Bass and Treble frequencies are boosted. When set to High-Pass (HP) operation, it acts as a variable Mid-Bass and Treble Boost. When set to Low-Pass (LP) operation, it becomes a variable Bass Boost. About Rockford Fosgate
