Diseńo modular. 150 W por 7 canales. Entradas: XLR y RCA 150M Modular Multichannel Power Amplifier The market for multichannel power amplifiers is crowded, competitive and compromised. Most conventional designs have shortcomings in terms of size, heat, or, most importantly, sonic performance. Audio Research has waited to enter this market until the technology to break through these compromises was fully developed. That time has come. The 150M is unlike any previous amplifier design you have seen from Audio Research. First, it is based on a truly modular design, with a main chassis capable of housoing up to seven individual power amplification modules, each rated at 150 watts continuous into 8 ohms, 300 watts into 4 ohms. These power modules employ a unique switching amplifier that modulates its frequency with amplitude/power demand - yielding a highly efficient circuit that generates very little heat. It's called a "Class T" design, and it makes the 150M ideal for any imaginable custom-installation application. Further, the modules are a plug-in design that attach internally via multipin connectors, so modules can be added or replaced as needed by a qualified technician. Each module may be fed with either a balanced or single-ended signal (there are input jacks for both), and each module has a pair of gold-plated 5-way binding posts for outputs. Input impedance is 150k ohms single-ended and 300k ohms balanced, with identical overall gain in either mode. In addition, pairs of modules may be bridged at the factory for four times the output (600 watts into eight ohms, each pair). Like every other Audio Research power amplifier, the 150M was developed to meet the most challenging sonic criteria. Power supply design and individual module layout have been optimized to yield stunningly musical results whether running two channels or seven. We believe that 150M begs comparison with any solid state amplifier available, and in fact has the important hallmarks of our tube designs: a natural, spacious soundstage, great bass definition and impact, sweetly resolved highs and lifelike musical dynamics. Whether playing back an adventure-film soundtrack or a concert video, the 150M stays composed and natural-sounding like no other multichannel design we've heard. Used with your favorite a-v processor, the 150M produces more musical results with less listener fatigue. The 150M may be ordered with one to seven power modules installed.
