150 watts x 7 channels Designed AND Built in the UK, compares with amps costing $6000 to $8000. Pretty amazing sounding. This amp has an amazing sound, rich, dynamic, transparent and natural. This is an incredible opportunity to gain amazing British voicing and performance along with meticulous manufacturing quality, This power amp is worth every penny of the asking price, however reasonable offers will be considered.
A high-powered multichannel power amplifier is an unusual product for a British company, but Arcam has evidently decided that they needed to crack the American home theater market. They chose to enter with a 150Wx7 (into 8ohms; 230Wx7 into 4ohms), modular design. Each amp module—one per channel—includes rectification and 20,000F of storage capacitance, all fed by two 1500VA toroidal power transformers. According to Arcam, this ensures that each module can deliver full output at all times. The ARCAM P7 Multichannel Power Amplifier will deliver equally breathtaking results from both music and home cinema sources. It will enthrall even the most experienced and discerning listener.
ARCAM FMJ P7 A completely modular design, with 7 identical and fully isolated power amplifiers, these may be daisy chained for bi-amping or tri-amping suitable loudspeakers. Each amplifier module has its own bridge rectifiers and 20,000 micro-farads of storage capacitance, fed from a total of 14 individual windings on the p7`s two massive 1500va toroidal power transformers. This arrangement ensures near perfect isolation between the channels for the avoidance of hum loops. It also means that each channel can always deliver its full rated continuous output power of 150 Watts into 8 ohms or 230 Watts into 4 ohms, irrespective of what the other channels are doing. The advanced current feedback circuit topology used in the p7 is a further development of that used in Arcam`s award-winning a85 and a32 amplifiers and has ultra low distortion together with exceptional dynamic range and transient response.
The p7 is a thx specified, 7 channel power amplifier which has been designed to deliver reference standard amplification in high performance audio-video installations. It is the perfect partner to the av8 processor, but will also complement the performance of any other high-quality preamp processor. As well as being technically superb, great attention has been paid to the aesthetic design of the p7 to ensure it will look stunning in your home installation. The p7 represents a tour-de-force in amplifier design. Certain to enrich your listening experience, its abundant power and finesse firmly positions Arcam in a small, select group of world-class producers.
As the p7 amplifier is capable of delivering over 1.6 kilowatts of continuous undistorted audio power, there were a number of engineering challenges that have had to be overcome to ensure both short and long-term reliable operation. Each channel uses four Sanken heavy duty bipolar output transistors firmly bolted to a large custom designed aluminum heat sink. These heat sinks are thermally very efficient so that, under normal conditions, the amplifier needs only convection cooling and is thus silent in use. With so much power on tap the p7 is equipped with a heavy duty mains cable and socket, coupled to a microprocessor controlled "soft-start" sequencer which, to minimize mains inrush currents, turns on the channels one by one. This system is powered from its own small toroidal power transformer, permitting the p7 to be remotely switched in and out of standby via a 12-volt trigger input.
ARCAM FMJ P7 The microprocessor continuously monitors the condition of each channel, including temperature, output current and dc offset, to ensure correct operation or instant shut-down under fault conditions. It also controls a variable-speed cooling fan, for those rare occasions when convection cooling is not enough. The p7 features a beautifully contoured front panel and integral air intake slot, with 7 multicoloured LEDs to show the operating status of each channel. The whole case is made of heavy gauge aluminum, which helps the overall sound quality due to its excellent thermal and non-magnetic properties. Because it weighs over 30 kg, even the p7`s feet are made from machined aluminum, complete with easy slide plastic inserts to help with installation.
