Rockford is one of the oldest and most respected brands in car audio history, and has been pumping out high quality, great-sounding gear since 1973. By pioneering ideas like the Punch EQ (boosting frequencies below 45Hz and above 20Khz for improved in-car music response) and using MOSFET circuitry to power in-car amplifiers, Rockford Fosgate paved the way for modern in-car electronics and hasn't slowed down since. The P400-4 features an ultra-small small footprint, and a clean, simple design that looks great no matter where it's installed. Dynamic Thermal Management ensures even heat dissipation across the entire heatsink for maximum efficiency and cooling. Rockford Fosgate amplifiers combine raw, clean power, with sleek, smart designs that are easy to install and look great in any car. All Rockford amps are CES-2006 compliant, which means the power listed is the actual power delivered, and each amp includes a birth certificate to prove it. But don't let the small size fool you; this petite powerhouse, which can easily fit under any seat, packs quite a punch! The P400-4 is the perfect companion for two pairs of coaxial or component speakers, or a pair of speakers and a simple subwoofer system. The P400-4 delivers 50 watts of clean power to for channels in stereo mode, or 200 watts per channel when bridged down to a two channel amp. But what exactly sets a Rockford Fosgate amplifier apart from the competition? Plenty. Keeping Things Clean and Cool The amplifier's job is to produce power, and lots of it. But a side effect of creating power is heat, and that is an electronic component's worst enemy. Rockford tackles this problem by incorporating a cast aluminum heat sink, Dynamic Thermal Management, and MEHSA³ technology to every amplifier, resulting in a significant reduction of the amplifier's operating temperature. The cast aluminum heat sink surrounds three of the four sides of the amplifier's circuit board, which maximizes the cooling surface area, and since the heat sink is cast it offers 30% better cooling ability over extruded designs. When combined with Rockford's patented Dynamic Thermal Management (DTM), cooling efficiency is taken one step further. DTM distributes heat evenly across the heat sink where other heat sink designs can create dangerous hot spots in the amplifier. Rockford also developed MEHSA³ technology for the MOSFET (metal–oxide–semiconductor field-effect transistor ) power transistors. MEHSA³ (Maximum Efficiency Heat Sink Application- Third Generation) maximizes heat transfer from the MOSFETs to the heat sink for up to five times better heat transfer. By keeping the internal components cool, the amplifier maximizes efficiency, produces more power, and reduces distortion for increased sound quality. Not only does the P400-4 produce lots of clean power, it also delivers exceptional sound quality. Differential input circuitry measures the positive and negative input signal as it enters the amp and subtracts the voltage common to both conductors (noise), resulting in a crisp, clean signal for maximum sound quality. The use of TRANS-ana circuitry, borrowed from pro-audio company, Hafler, also adds to the sound quality recipe. The TRANS-ana circuit simplifies the audio signal and allows it to travel through the amplifier as a low voltage signal before it reaches the amplification stage. This improves the sound quality of the signal, delivers cleaner performance, and improved reliability. The P400-4's TO-247 MOSFET power transistors offer 60% more metal tab area than the industry standard TO-220 MOSFETs, which means more power, better cooling, and improved sound quality. Once the signal reaches the amplification stage, it's greeted by much beefier MOSFETs than what is traditionally used in most amplifiers. Rockford uses TO-247 MOSFETs compared to the somewhat standard and less efficient TO-220 MOSFETs. TO-247s offer 60% more metal tab area, which means more power capacity, better heat dissipation, and lower impedance capability. In other words, these things produce some serious power with very little effort. Sound Shaping and Equalization Upgrading speakers and adding subwoofers will always improve your sound system, but in order to maximize how well the speaker performs requires a bit of equalization and sound shaping. Door and dash speakers can play a pretty broad range of frequencies, but realistically cannot produce the ultra-low frequencies that a subwoofer is designed to produce. Just the opposite is true for a subwoofer. It cannot produce mid or high frequencies well; its job is to pump out gut-punching bass. To make sure your speakers are working at their maximum efficiency, Rockford incorporated a fully variable 12db high-pass and low-pass crossover into the 400-4. With a twist of the dial, the high-pass crossover can be adjusted to eliminate any frequencies below a certain point between 50Hz and 500Hz. If using the 400-4 for a subwoofer system, switch on the low-pass crossover and adjust the crossover to eliminate higher frequencies, adjustable between 50HZ and 500Hz. The Punch EQ can be tweaked to deliver up to an 18dB increase at 45Hz for subwoofers, or up to a 12dB increase at 12kHz for speakers. This improves overall sound quality and overcomes audio response problems common to the automotive environment. Rockford Fosgate built a reputation around the Punch EQ, which is incorporated into their Punch amplifiers, and allows the amp to better shape the sound quality of your speaker or subwoofer system. When using the high-pass crossover, the Punch EQ can boost high frequencies above 12kHz anywhere from 0-12dB. This frequency range is often lost to road noise and other factors, and the Punch EQ allows you to dial up that range for perfect sound. If the low-pass filter is on, the Punch EQ can add a bit of boost (up to 18dB) to the 45Hz frequency range. This gives you the ability to dial in a little extra rib-rattling bass to your music that can be lost due to the compact size of most car interiors. Making the Connection All controls and connections are located on one edge of the amplifier, making it easy to access all controls and guaranteeing an easy, clutter-free installation. The P400-4 will accept up to 4-gauge power and ground wire, and all connections are neatly housed in c-clamp type connectors that terminate inside the amp's chassis. This adds a cleaner appearance to your install and ensures no fly-away wires can stray to other terminals causing possible shorts. All connections are recessed into the amplifier's chassis and located on the bottom edge of the P400-4, for a clean, uncluttered install that looks great in any car. Speaker connections also use a similar clean audiophile design, and will accept up to 12-gauge wire for maximum signal transfer to your speakers or subs. The amp features a single RCA connection flush with the amp's chassis, further enhancing the overall clean appearance. An RJ-45 jack is for connecting an optional remote-mounted Punch EQ control and is located next to the crossover and Punch EQ controls. The remote PEQ controller can be installed up front and within easy reach to give you on-the-fly control of your Punch EQ settings. Pushing Power The P400-4 is a flexible amplifier and is stable at two-ohms. This amp is perfect for powering front and rear speakers in four-channel mode, delivering 50 watts of clean power to each speaker. Or you can mix things up a bit and use the P400-4 to drive two front coaxial or component speakers at 50 watts RMS and bridge the rear channel to deliver 200 watts to a subwoofer.

Product Description Yamaha A-S1000BL Natural Sound Integrated Stereo Amplifier In Black From the Manufacturer The Yamaha A-S1000 Integrated Amplifier: An Affordable Sound Luxury The brilliantly expressive capabilities of Yamaha's floating and balanced design is now available to a wider range of music lovers. The power amp, power supply, and phono EQ circuits that contribute to the A-S1000's high sound quality are identical to that of the more expensive Yamaha A-S2000, while the line amp section and volume and tone circuits are nearly the same. Designed to take full advantage of the excellent sonic qualities of the matching Yamaha CD-S1000 Super Audio CD Player, the A-S1000 will also bring out the best of other high performance components. Heat sink Huge power transformer Custom-made block capacitors Preamp board Yamaha's All-New Approach to Achieving Superior Performance The development of the modern audio amplifier began in the 1960s with the introduction of full-transistor amplifiers. In the 1970s, pure complementary configured power amps appeared, made possible by high output PNP-NPN transistors, and became the dominant type of analogue amplifier. Now digital amps have become popular for their high conversion efficiency and superior operating precision, as well as for their lower weight, size, and heat production as compared to analogue amps. Some manufacturers of audiophile-quality amps are working to improve the traditional pure complementary analogue amplifier, while others are seeking to achieve higher sound quality from digital amplifiers. But Yamaha has developed a third, superior approach. The Floating Balanced Power Amplifier uses patented technologies featuring power transistors with the same polarity at the output stage to achieve completely symmetrical operation. This method, used in the A-S1000, combines a floating balanced power amp section with a high quality preamp section. Simpler in configuration yet with many of the same sound quality features as the ultra high-end A-S2000, it will deliver excellent performance with the CD-S1000 Super Audio CD player and other high quality components. How Does the Floating Balanced Amplifier Design Work? Completely symmetrical left-right construction View back panel Floating Balanced Power Amplifier With the A-S1000, Yamaha has taken the bold step of using a floating balanced configuration to update the power amplifier for serious music fans. This method, which is completely different from the pure complementary circuit that has been the main type for the past four decades, features identical polarity on the plus and minus side of the output stage. By completely isolating the plus and minus sides of the left and right channels of both the NFB and power supplies, it achieves perfectly symmetrical operation in the output stage. The use of four sets of floating power supply units (not connected to earth), provides further operating precision. The result is very low levels of noise and distortion for exceptionally pure and transparent sound quality. Triple Parallel Electronic Volume and Tone Controls Conventional audio amps have the volume and tone control circuits arranged in a series (in line); when the tone controls are used, the signal route becomes more complicated, which can lower sound quality. Many high quality amps therefore have a default circuit that can be selected to bypass the tone controls, but this forces you to choose between tone control and optimum quality. The A-S1000 is one of the first amplifiers to avoid this problem by employing triple parallel electronic volume and tone controls, providing maximum sound quality even when the tone controls are used, because the signal goes through fewer ICs, so there is less noise. When the tone controls are set to the center position, the passive element used for tone control is bypassed, so the three volume elements connected in parallel operate solely to drive and control the volume for more efficient use of the power output. Each volume element is an ultra-high quality device and an analogue potentiometer is used to provide a very smooth operating feel. Fully Discrete Phono Equalizer and MC Head Amp The A-S1000 uses a fully discrete phono equalizer circuit, whose quality is comparable to those in high-end control amps. And with its high priority on maximizing musical response, it is also equipped with a discrete head amp for MC cartridges. If you enjoy listening to records via high performance cartridges, the A-S1000 is an ideal choice. Power Supply That Cleans Itself Power is provided by four large-capacity power supplies that are completely isolated from earth. In the preamp stage, the combination of a low-current circuit that prevents the occurrence of noise due to current fluctuation and 12 shunt regulators supply all stages with clean and stable power, so you won't get distortion from a dirty power source. The extra-large power transformer, the carbon sheath block capacitors and other parts that directly affect sound quality were chosen only after extensive testing. Symmetrical Construction Mimics the Benefits of Having Separate Amps Although it is an integrated amplifier, the A-S1000 has a completely left-right symmetrical construction that makes it virtually the equal of separate amps. A central reinforcing bar ensures that the chassis is totally rigid. Specially Designed Feet Dampen Vibration to Reduce Jitter The base is equipped with height-adjustable, solid steel feet that maximize stability and thoroughly dampen any external vibration.
