By further pursuing the concept of Air Circuit™, we have eliminated filters, strengthened the power supply (securing approximately 1.5 times the necessary capacity), and reviewed the pattern. (S stands for "Straight.") As a result, while achieving a 30% reduction in size compared to R-208, we have realized a powerful and pure sound quality. We have embodied BEWITH's sound creation, which amplifies and transmits even the finest musical signals straight, in this size.
