CEA-2006
Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.
Differential Inputs
Differential input circuitry measures the voltage of both the (+) and (-) input signal. The circuitry subtracts the voltage common to both conductors (noise) resulting in only the clean signal. This allows only clean signal to enter the amplifier.
Discrete Surface Mount
DSM--An industry-leading manufacturing process, DSM utilizes high-speed robotics, high-quality 1% tight-tolerance parts and large board traces. The discrete components are laser etched to meet a particular value and a very low tolerance. This lower tolerance improves the efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature. These superior components are used by aerospace, automotive, and cellular manufacturers.
Dynamic Thermal Management
Heat is often inefficiently dissipated across a heatsink causing "hot spots". This impacts important design goals which are:
- Keeping internal components cool.
- Maximizing potential of all components.
- Reducing distortion for better sound quality.
- Increasing efficiency to produce more power.
Rockford Fosgate engineers have developed an award winning cooling design called DTM. This patent pending design seamlessly manages the output of power supply temperatures, while evenly distributing the excess heat across the entire amplifier.
MEHSA3
MEHSA3 (Maximum Efficiency Heat Sink Application - gen. 3) is a proprietary process that yields up to five times better heat transfer than traditional FET mounting techniques, using the exact same components. A multi-layer insulated metal substrate operating with minimal thermal resistance spreads heat both downward & outward to quickly dissipate heat from each device across the heatsink. This process 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 as well as provide consistent thermal stability. The 3rd generation creates a dielectric layer between the ceramic topside and the aluminum base that retains all of the electrical isolation and capacitive coupling of the original MEHSA material increasing it's thermal conductivity. The higher power handling results in a 20% reduction in thermal impedance.
NOMAD
NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.
Punch EQ2
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 car he tested. Jim discovered three problems that were common to all cars:
- A midbass hump between 100-275Hz
- A steep roll-off of high frequencies from 2kHz up to 20kHz
- Reduced bass response below 50Hz
The Punch EQ on-board equalization circuit helps correct for these acoustical deficiencies in the listening environment. When set to Low-Pass(LP) operation, it becomes a variable Bass Boost. When set to High-Pass (HP) operation, it acts as a variable Mid-Bass and Treble Boost. When set to All Pass (AP) operation, both Bass and Treble frequencies are boosted.
TO-247 MOSFETs
Rockford Fosgate amps use custom TO-247 MOSFETs. These have 60% more metal tab area for more power capacity, lower impedance and improved heat dissipation over traditional TO-220 MOSFETs found in competitor amps.
TRANS•ana
An award winning studio quality circuit borrowed from the pro audio company Hafler. TRANS-ana is a sound quality circuit that is a standard in the recording industry that simplifies the signal path of the amplifier, allowing the signal to travel through the amplifier at a low voltage. The result: Greater reliability, cleaner performance and exceptional musicality, speed, and durability.
