TASSO Audio's "Horse Treading on Flying Swallow" (referred to as Fade-in) system is an ultra-compact plug-and-play line array system, focusing on three core needs: flexible deployment, high-power output and modular array configuration. It can fully adapt to various sound reinforcement application scenarios, balancing practicality and professionalism. The Fade-in system seamlessly integrates cutting-edge sound reinforcement technology concepts into the overall design, consisting of two core components — Fade-in array speakers and Fade-in active subwoofers. Its functions cover a wide range from small events to large-scale professional scenarios. It can not only be used as a suspended line array system for professional live concerts and music festivals, but also flexibly match ground-mounted or suspended subwoofers according to actual needs, adapting to multi-scenario application requirements. In addition to the excellent system flexibility, the Fade-in system stands out with its advanced functional design and core technologies, aiming to simplify the operation process of installers, rental companies and bands, and improve work efficiency.

The Fade-in full-range array speaker is a precision-designed ultra-compact coaxial line array product. It is equipped with an optimal combination of an 8-inch low-frequency unit and a 2-inch high-frequency unit, paired with a simulation-optimized acoustic lens waveguide, which can achieve clear, transparent and layered sound quality output. When multiple speakers are vertically combined, they can form excellent line sound source characteristics, further improving the uniformity of sound field coverage. At the same time, the product adopts a miniaturized and lightweight design, which can be moved and installed by a single person. In high-end application scenarios, it can minimize the visual footprint, achieving a dual improvement in sound quality and visual effect.

The Fade-in active subwoofer adopts a unique 6th-order band-pass acoustic structure, which can simultaneously achieve deep low-frequency extension and abundant dynamics, making up for the low-frequency shortage of full-range speakers and creating a full and three-dimensional sound field effect.

The product has a built-in three-channel power amplifier module, which can not only efficiently drive its own 18-inch speaker unit, but also directly drive 2 Fade-in full-range speakers through active frequency division, simplifying the system connection process. The power amplifier has 4 preset scene modes, which can be quickly called according to different usage scenarios, truly realizing plug-and-play without complicated debugging, and greatly reducing the operation threshold.

It is worth mentioning that TASSO Audio named the "Horse Treading on Flying Swallow" system "Fade-in" in English, which means "from nothing to something, gradually reaching perfection". It appropriately interprets the core characteristics of the product — whether it is the compact and unobtrusive visual presentation, or the flexible and layered auditory experience, the Fade-in system has reached the first-class level in the industry, perfectly practicing the design concept of "From Nothing, into Infinity".
