Outline (欧浪) GTO的理念是生产一种灵活、适应性强、易于操作的大型线性声源扬声器系统,能够提供满足最挑剔的工程师、租赁公司和项目承包商的音频性能。

GTO是Grand Touring Outline的首字母缩写, 体现了我们专门为大型扩声应用设计的系统理念。 2002年,我们推出了Butterfly系统,包含了许多独特的Outline (欧浪) 工程理念,给我们带来了很多来自世界各地的新朋友和客户。

GTO得益于自然发展的过程,保留了Butterfly工程项目所证实的基本设计原则,将其延伸到一个新的系统,该系统在远距离投射提供更高的声压级、更多的控制、更高的分辨率、更快的瞬态响应和无与伦比的一致性。

从Butterfly中保留的基本设计元件之一是2002年Outline (欧浪) 获国际外观设计专利的V形前挡板,我们称之为“V-Power理念”。 这个突破性的设计可使单独的声源耦合成一个阵列时,比传统的线性声源系统更紧密地结合在一起。这有利于高频模块之间良好的声音耦合,产生平滑且延伸的高频响应。它还通过一个阵列创建了理想的“不间断挡板”形状,最大限度地减少了中高频的衍射和恶化,有助于系统的远场性能。

GTO紧凑型箱体,使用10个传感器,容积仅为340升(74.79 加仑)。 使用4个3寸振膜压缩驱动器,每个都配备我们的专利D.P.R.W.G. 双抛物面反射波导管(其波导管首次应用于Butterfly系统中),均通过单个插槽通道同步传输。 4个8寸中频单元,中频和高频均通过水平散波导管通道同步传输。 2个15寸锥形传感器低频单元,提供了出色的清晰重低音和快速的瞬态响应。

尽管GTO箱体单个传感器的含量非常高,但我们仍然设法将重量降至仅96 kg (212 lb)。

该设计使用了许多省重的元件, 这一成功的最大贡献是使用航空和航天工业的太空时代铝合金,这是我们用于集成的吊挂硬件,其优于钢材。这一创新技术将每个箱体的硬件重量减少66%,仍然足够坚固可搭载总重达2.4吨多达24只GTO音箱组。 GTO箱体之间的斜角可以在0°和5°之间以0.5°的增量进行调节,并增加了一个0.25°的位置用于阵列中最顶部的箱体,以提供额外的远场性能控制。由于箱体之间的斜角会影响驱动单元之间的物理距离,因此线性声源系统的整体性能需要对这些参数进行精确的控制。与箱体吊挂硬件集成的测角仪(斜角指示器)可精确调节各个箱体之间的角度,然后通过插入钢制插销将其锁定。

我们专门设计了GTO-DF音箱用作下区补声。 这个模块化音箱在垂直平面上可提供25° 的声场覆盖,并与GTO共用吊装硬件。 如果需要上区声场覆盖,可以使用Butterfly和Mantas音箱搭载在主吊挂框架上方。 需要垂直声场覆盖的大型场馆项目,这两种解决方案均可提供足够的声场覆盖。

Outline’s concept for GTO is to produce a large format line-source loudspeaker system that is flexible, adaptable, easy to use and which provides audio performance that meets the demands of the most discerning engineers, rental companies and production managers.

GTO is an acronym for Grand Touring Outline, which describes our concept of a system engineered specifically for large-scale sound reinforcement applications. In 2002 we launched the Butterfly system which contained a number of unique Outline engineering concepts, and which has brought us many new friends and customers around the world.

GTO benefits from a process of natural evolution which retains the basic design principles, proven within the Butterfly project, and expands them into a new system which provides greater SPL, more control, improved resolution, faster transient response and unrivaled uniformity in long-distance projection.

One of the essential design elements retained from Butterfly is the V-shaped front baffle, for which Outline was awarded an international design patent in 2002, and to which we refer as the ‘V-Power Concept’. This ground-breaking design allows individual sound sources to be positioned, when coupled in an array, much closer together than in conventional line-source systems. This facilitates superior acoustical coupling between high-frequency modules thus producing a smooth yet extended HF response. It also creates the ideal ‘unbroken baffle’ shape through an array which minimises diffraction and deterioration of the mid-high frequencies, thus contributing to the far-field performance of the system.

GTO cabinets contain ten transducers in a compact cabinet with an internal volume of just 340 litres (74.79 gals). It features four 3-inch diaphragm compression drivers, each loaded with our patented D.P.R.W.G. (first used in Butterfly), and whose combined output is channelled through a single output slot. Four 8-inch drivers produce the midrange frequencies, which are output via the same horizontal dispersion waveguide as the HF. Two 15-inch cone transducers generate the low frequency range, providing tremendous depth, articulation and fast transient response.

Despite the very high concentration of individual transducers within a GTO cabinet, we have managed to keep the weight down to just 96 kg (212 lb). The design contains a number of weight-saving components, but the greatest contribution to this success is the use of a space-age aluminium alloy from the aerospace industry, which we have used for the integrated flying hardware in preference to steel. This innovation reduces the per cabinet weight of the hardware by 66%, yet is strong enough to fly up to 24 GTO cabinets with a total weight of 2.4 tons. The splay angle between GTO cabinets is adjustable between 0° and 5° in 0.5° increments, with the addition of a 0.25° position intended for the uppermost cabinets in an array to provide additional control in far-field performance. Since the splay angle between cabinets affects the physical distance between drive units, the overall performance of a line-source system demands precise control over these parameters. A goniometer (a splay angle indicator), which is integral to the cabinet flying hardware, allows precise adjustment of the angle between individual cabinets which is then locked by insertion of a captive steel pin.

For Downfill applications, we have specifically designed the GTO-DF. This modular cabinet gives 25 degrees of coverage in the vertical plane and attaches by using the same rigging hardware. If upward system coverage is required, it is possible to mount Butterfly and Mantas cabinets above the main flying frame. Both these solutions provide adequate coverage in venues where a very large vertical dispersion is required.
