■Product Introduction
The JS-2 and JS-3 are simple, handy devices that split microphone signals and supply them to sound systems like PA systems. The transformers, which are crucial for sound quality, are world-class JENSEN transformers, ensuring microphone signals are sent to the system without distortion or other degradation.

In large-scale PA systems that use multiple cables, junction boxes with splitting functions are commonly used between the FOH (venue) main console and monitor console. In recent years, with the development of DAWs, opportunities for multi-track recording of live performances in small clubs and other venues have increased, and many engineers have begun to demand splitters that meet high standards, even on a smaller scale.

The JS-2 and JS-3 are ideal for such applications. They employ the highest-quality JENSEN transformers for splitting, eliminating issues like hum and degradation of sound quality. Like other Radial JDI and J48 models, they feature durable bodies and parts that withstand long-term use with minimal deterioration, making them ideal for a variety of applications, including live performances, broadcasting, recording, and installations.
