簡介

+ Usher R-1.5 Power Amplifier The R-1.5 amplifier is designed to drive all speakers to produce a warm-toned "vacuum tube" sound quality. The use of high-quality components, including metal film resistors and film capacitors, enhances Arthur's reputation in high-quality manufacturing. High-power bipolar transistors designed by Motorola can meet complex power and current requirements. Its large-scale AC power transformer can be used in conjunction with a high-capacitance filter system to obtain the purest sound. Other features include Burrow-Brown OPA2134P Sound Plus series arithmetic optimized amplifiers, bridge switches for mono function operation, banana plugs and direct-lock bare wire terminals, as well as additional optional balanced inputs and on the front and rear panels. Large handle. R-1.5 擴音器旨在驅動所有的揚聲器，產生溫暖音色的「真空管」音質。採用優質部件製造，包括金屬膜電阻和薄膜電容，提升雅瑟在高品質製造方面的聲譽。由摩托羅拉設計的高功率雙極晶體管可滿足複雜的功率和電流要求。其大規模交流電源變壓器可與高電容濾波系統配合使用，獲得最純淨的聲音。其他特性還包括Burrow-Brown OPA2134P Sound Plus系列運算優化擴大器、用於單聲道功效操作的橋接開關、可使用香蕉插頭和直接鎖裸線端子，以及額外可選的平衡輸入和前後面板上的大型把手。
