K4-1400 and K4-1700 are two digital power amplifiers of Sinbosen. Recently Sinbosen updated and upgraded the panels of these two power amplifiers.

     The upgraded digital amplifier panel has enhanced visual appeal. Sinbosen designs panels with careful attention to detail, incorporating a sleek and contemporary aesthetic. The panel's refined look adds a touch of elegance to the amplifier, making it visually appealing in a variety of professional settings, including live performances, studios, and installations.

     This time the panel was upgraded with high-quality materials. Thicker and stronger construction enhances the overall durability of the amplifier enclosure. This provides better protection for internal components, reduces the risk of damage from external impacts and is durable.

These improvements make it easier for users to operate and adjust the amplifier's settings, ensuring a more convenient and hassle-free experience. Whether adjusting volume, selecting an input source or controlling EQ settings, the upgraded panel provides a user-friendly interface.
