现代现场扩声始于开发可靠的高功率PA放大器，能够实现良好的声音再现，可以大规模生产和销售，价格合理。早在1976年，英国一家的名为RSD的录音棚设计公司，就是最早设计和制造此类放大器的公司之一。此类放大器不但弥补了从美国进口设计的放大器——非常昂贵且极少数机器可用的性能，每通道只能输出不超过几百瓦的缺点，而且这类放大器非常实惠。RSD的目标是将录音室的纯净音质带到音乐会舞台上。他們开发了RSD 800B，这是一个每通道为800瓦的放大器。它们供不应求，被大量抢购，提供给很多大型团体的表演秀和巡回演出，如Pink Floyd摇滚乐队的巡回演出。随着1970年代后期朋克音乐的爆炸式增长，随之而来的是大量演出，PA放大器的使用成就了录音行业，所有公司都使用RSD 800B放大器。重要的是，这些放大器非常实惠，这意味着即使是很小的乐队开始他们的明星之路，也可以使用一個很棒音质的PA系统演出，该系统甚至可以安装在旅游车的后部。 

Modern live sound production began with the development of reliable, high power PA amplification, capable of good sound reproduction that could be mass produced and marketed affordably. Back in 1976 a company called RSD (Recording Studio Design) based in England, was among the first to design and build such amplifiers. Not only did they challenge the engineering and performance specifications of the very few available, hugely expensive, imported US designs that could put out no more than a few hundred watts per channel, they were indeed affordable – very affordable. RSD’s goal was to bring the pure sound quality of the recording studio to the concert stage. They developed the RSD 800B, an 800 watts per channel amplifier that they could not build enough of. They were snapped up in huge numbers to power extravagant concept shows and arena tours for mega groups such as Pink Floyd. Then came the explosion of Punk music in the late 1970’s, bringing with it, the gigging revolution, PA hire grew into an industry and all the companies used the RSD 800B. Just as importantly these amplifiers were extremely affordable, meaning that even the smallest bands setting out on their road to stardom could gig with a great sounding PA system that would easily fit in the back of the tour van.

RSD 继续开发突破性的产品，推出第一個紧凑型调音台和首批8路总线家庭录音混音台，专为使用新型八轨磁带机而设计。正是这台混音台“ Studiomaster 16 - 8 ”，见证了公司名称从RSD到录音大师Studiomaster ，并搬迁到位于英国卢顿的新工厂。在整個 80 年代和 90 年代，RSD公司新的研發部門进行了一系列的创新产品的开发，不断向各个级别的乐队和词曲作者提供能保留以前大型录音室保留的功能和技术并且实惠的产品。在这些开发的产品中，最早的四个总线混音器被设计为新型键盘乐队的子混音器，带有合成器、音序器和鼓机的机架，并作为许多家庭录音师的主混音器。

RSD continued to develop ground breaking products, introducing the first compact monitor console and one of the first 8-bus home recording mixing desks, designed to operate with the new breed of eight-track tape machines. It was this mixing desk, the ‘Studiomaster 16-8’ that heralded the change of company name from RSD to Studiomaster and the move to a new factory based in the town of Luton, UK where it remained for many years. Throughout the 80’s and 90’s, the new R&D department produced a string of innovative product developments, continually making available, features and technologies previously preserved by the big recording studios, to bands and songwriters of all levels. Among these developments were the first four bus mixers, designed as sub mixers for the new breed of keyboard bands, with their racks of synths, sequencers and drum machines and as a main mixer for many home recordists.

自带功放调音台的发明是下一個巨大的成功产品,成为了录音大师（Studiomaster）公司"标志性" 产品。“ Studiomaster 8 - 2 ”调音台融合了公司最擅长的性能，创造了一个紧凑、便携、帶有功率放大器的专业调音台。事实上，调音台中的 PA 系统，具有单独的左、右通道和监听通道。由于它的尺寸、功能和经济实惠性，这台调音台是世界各地演出音乐家、小型场地和排练室的礼物。随着更多产品的成功成为行业第一，例如，MIDI 自动化家庭录音台和预置可操作的数字效果处理器，该公司在音乐技术行业和大众市场继续占领主导地位。

The invention of the powered mixer was the next big success story that became the ‘signature’ Studiomaster product class. The ‘Studiomaster 8-2’ merged the two things the company did best, creating a compact, portable, professional mixing desk with integrated power amplification. Effectively a PA system in just one box, with separate left, right and monitor channel amplification. The powered mixer was a gift to gigging musicians, small venues and rehearsal studios the world over, due to its size, functionality and affordability. This, along with more industry firsts such as MIDI automation home recording desks and preset operable digital effects processors, the company continued its growth and mass market domination of the music technology industry.

今天，录音大师（Studiomaster）不仅是公认的音响行业传奇，他仍然是一家英国专业音频工程公司。现在归音王集团所有，位于中国宁波，是中国最大的音乐设备和专业音响制造商之一。他拥有全球分销、投资和量产设施，同时将产品开发、工程、战略管理、市场营销、分销和服务部门全部保留在英国米尔顿凯恩斯的新总部。

Today, Studiomaster is not only a recognised sound industry legend, it also still remains a UK based pro-audio engineering company. Now under the ownership of the Soundking group, among the largest musical equipment and professional audio manufacturers in China, it has access to worldwide distribution, investment and mass production facilities in Ningbo, whilst retaining its product development, engineering, strategic management, marketing, distribution and service departments all at its new headquarters in Milton Keynes, UK.

早在 1976 年, 录音大师（Studiomaster）在现代音乐设备行业中独树一帜是创新和以最具竞争力的价格提供优质产品。

Just as it was back in 1976, what sets Studiomaster apart in the modern musical equipment industry is innovation and the drive to offer premium quality products at the most competitive affordable prices.
