海外ニュース速報 [World]

Pass Laboratories will be introducing the Xs Preamplifier, which is Pass Labs’ new flagship of its preamplifier line, at the Venetian Tower suite 34-209 during CES 2013. The Xs Preamp is entirely new and designed to complement the ultimate performance standards of Pass Labs’ Xs-300 and Xs-150 amplifiers. The Xs Preamp is quieter than the XP-30 and has an improved power supply. In appearance, it resembles the Xs Amplifiers and features two large chassis built with a true dual-monaural topology. Pass Lab’s Xs preamplifier has several circuit boards fabricated from materials sourced in many cases from the military and high-speed computer sectors for their superior performance. Pass Labs has optimized each circuit board through an arduous trial-and-error process for top performance in each of the functional areas for which a board is employed. Circuit boards for power supply circuits have different requirements than ones for gain stages. In the Xs Preamp, each board is optimized for its specific use. Each of the two channels has its own power supply board, each with a refined circuit design and layout. Their 100,000-microfarad (uF) capacitors are optimized for low noise and high performance through the use of a variety of materials, from highly reliable electrolytics to a custom polypropylene. Newly available silicon carbide semiconductors further heighten performance by dropping noise below the level of Pass Lab’s XP-30 preamplifier. The circuit boards for the gain stages have been completely redesigned for maximum sonic impact. They employ a direct-coupled (DC), ultra-symmetric gain path with high-bias Class A circuitry, and feature auto bias and DC-compensation to maintain peak performance. An extra large, high-definition display addresses listeners� desire to know a music system痴 status even from across a brightly lit room. The 20-character display is easy to read and dimmable. The Xs Preamp comes supplied with a remote control. Its rear panel includes 6 inputs, a tape loop, dual-power input connections, dual balanced outputs, and variable outputs for bi-amping and use with multi-room systems.
