Footnote 1: Solid-state amplifiers are much more prone to blow out loudspeakers than were tube-type amps because of their superior low-frequency power-output capability. A subsonic pulse that would simply saturate the core of an output transformer may pass through a solid-state amplifier at close...
Acoustic Research tried to blend in with the other manufacturers, such as Advent, who experienced great profits with their fresh, modern loudspeakers. The slogan “The first accurate speaker for rock music” shows very well, how Acoustic Research tried to be young and modern on the one hand,...
Starting inside, Acoustic Research has opted for some of the finest audio components around. The Burr-Brown PCM1794A digital-to-analogue-converter is touted as the flagship DAC, and the Class A amplifier AR has used inside the M2 is equally highly regarded.That amp is a perfect example of ...
AR-M2便携播放机到手之前,我已经接到要对它进行评论的任务.Acoustic Research这个品牌对我来说并不陌生,毕竟我曾是AR音箱的用家.但对于AR推出便携播放机,我既觉得惊讶,又觉得有点陌生.或许我是一个比较传统的人,对这些老品牌推出针对年轻人用的音响,我在思想上会存在一定的适应期.不过,我并不会抗拒AR-M2.毕竟...
Class-D amplifierDirectivity patternThrough studying how to affect acoustic directivity with MATLAB software, it show that selection of a relatively larger surface of the transducer and a relatively closer transducer interval will be more preferable for directivity. While an array which possess more ...
The results of a fan noise data analysis and prediction effort using experimental data obtained from tests on the QF-1B research fan are described. Surface... DB Bliss,KL Chandiramani,AG Piersol - 《Unknown》 被引量: 2发表: 1976年 Analysis and Design of High-Efficiency Parallel-Circuit Cl...
The US transducer was driven by a waveform generator (33220 A; Agilent, Santa Clara, CA) and a power amplifier (75A250; Amplifier Research, Souderton, PA) and was calibrated using a hydrophone (HNR-0500; Onda, Sunnyvale, CA). The transducer has a −6 dB beam width of 3.54 mm...
These RF front ends require many more analogue components to be integrated in a compact form factor, driving research in RF integration into traditional digital processes. Many high-performance technologies require integration using microelectromechanical systems (MEMS)-first or MEMS-last process schemes8...
