Rockford Fosgate Punch P400-1 400-Watt Mono Amplifier
The Punch P400-1 mono amplifier is specifically designed for medium to high-powered subwoofer applications. It's variable crossover and built-in Punch EQ allow for precise tuning of Bass frequencies, and its 2-Ohm mono stability is perfect for running up to four 4-Ohm DVC subwoofers. You can also add-on the PEQ Remote Punch Bass to control equalization from under the dash or center console. Sized to fit under any seat, you can hide this amplifier and have them guessing where the amp is.Rockford Fosgate Punch Series AmplificationFor over 25 years, Punch amplifiers have set the standard in the car audio amplifier industry and they continue to do so today. It's the reason that they have become the most popular amplifiers in the world. Each of the Punch family amplifiers reproduce sonic perfection along with impressive power in a compact chassis.Perfect for use as a dedicated subwoofer or center channel amplifier.Click to enlarge.Heavy duty, nickel-plated clamp wire connectors.Click to enlarge.P400-1 Features12dB/octave crossover4 Gauge power/ground terminalsAudiophile grade speaker connectionsMOSFET output stageMOSFET power supplyTop Mounted LED IndicatorsCEA-2006Power 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 InputsDifferential 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 MountDSM--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 ManagementHeat 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.MEHSA3MEHSA3(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.NOMADNOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.Punch EQ2In 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 100-275HzA steep roll-off of high frequencies from 2kHz up to 20kHzReduced bass response below 50HzThe 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 MOSFETsRockford 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•anaAn 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.P400-1 SpecificationsNumber of Channels:1Rated Power:200W x 1 @ 4-Ohms RMS400W x 1 @ 2-Ohms RMSTotal Power:400 WattsDynamic Power:314 Watts x 1 @ 4-Ohms 0 degrees Res515 Watts x 1 @ 2-Ohms 0 degrees ResBridgeable:NoEfficiency (average):70.5% @ 4-Ohm66.5% @ 2-OhmCrossover Controls:High-Pass (HP): 50Hz-500Hz 12dB/octave ButterworthLow-Pass (LP): 50-500Hz 12dB/octave ButterworthTone Controls:Punch EQ2 Bass: 0dB to +18dB @ 45Hz and/orPunch EQ2 Treble: 0dB to +12dB @ 12kHzFunction depends upon LP/AP/HP switch positionSignal Input:Low level: 1 RCA pairSignal Output:n/aPower Input Connector:BlockPower Wire Gauge:4 AWGSpeaker Output Connector:Screw terminal barrier stripSpeaker Wire Gauge:8 AWG to 18 AWGHeat Sink Type:Cast aluminumCooling:ConvectionRemote Controls:n/aVisual Indicators:PowerThermalProtectCircuit Topology Class:Class A/BFrequency Response:20Hz to 20kHz +/- 1dBShipping Weight:TBADimensions (HxWxL):2.25 x 7.625 x 9.0 (in)5.71 x 19.37 x 22.80 (cm)Thirty Years of Rockford FosgateRockford Fosgate products have been designed and engineered in Tempe, Arizona since the beginning. Rockford's 30 year reputation is grounded in engineering and manufacturing some of the finest audio products in the world.
